DIY Pinhole Viewer

Try this at Home - Eclipse Pinhole Viewer 

This DIY pinhole viewer can be used to observe the sun any time, but it will be especially useful for the solar eclipse on April 8th! For more information about how to experience the eclipse at the Science Center, visit www.osc.org/eclipse.


What is an annular solar eclipse? 

A solar eclipse happens when the Moon passes between Earth and the Sun, casting a shadow on the planet. However, there are different types of solar eclipses. A total solar eclipse happens when the Moon completely blocks the face of the Sun, causing a brief period of darkness during the day. A partial solar eclipse happens when the Moon, Sun, and Earth are not perfectly aligned, causing only a part of the Sun to be covered and giving it a crescent shape. An annular solar eclipse happens when the Moon is at its farthest point from Earth, making it appear smaller than the Sun in our sky. This creates a ring effect around the Moon. The term "annular" refers to this ring effect.

What is going to happen?

The April solar eclipse will begin at 1:46 pm, peak at 3:03 pm, and end at 4:17 pm giving viewers an adequate amount of time to see this celestial event as it happens. ⚠️ IT IS NEVER SAFE TO LOOK DIRECTLY AT THE SUN DURING A PARTIAL ECLIPSE WITHOUT SPECIALIZED EYE PROTECTION! This can cause severe retina damage. Our staff will be on hand to highlight how to correctly use solar eclipse glasses.


 

You can use this DIY pinhole viewer to safely experience the eclipse from anywhere!

Materials:

  • Cardboard box (like a cereal box, skinny delivery box, etc.) 
  • Aluminum foil 
  • Paper
  • Tape
  • Scissors
  • Pointy thing 

 

How to make your DIY pinhole viewer! 

  • Figure out where your pinhole will be! You want sunlight to shine through the hole and travel as long as possible inside the box before hitting the other side. 
  • Trace the bottom of the box on a piece of paper. Cut out the paper and tape it to the inside of the box. This is your projection screen! 
  • Carefully cut two holes in the top of the box. One will be your viewing window, and the other the pinhole.  
  • Cover one of the holes with tin foil and poke a tiny hole to make your pinhole. 
  • Now just head outside! Hold the box so you are looking down through the viewing window and position yourself so that the sun shines onto the projection screen.

Make a model that shows how water flows over different land shapes! 

A topographic map shows different land features, like mountains, ravines, and plains, using curved lines or colors to show altitude. It’s an easy way to show a 3D view of something on a flat surface. Topo maps are commonly used by hikers, surveyors, government workers, and engineers, among other people.  

Our model won’t be flat so it isn’t exactly like a topo map, but it will show the same type of information! 

Ready to make your own? Follow the written steps below! 


Materials you will need: 

  • Half sheet of paper 
  • Washable marker 
  • Dropper bottle (your adult can also make one by using a thumb tack to poke a whole in a water bottle cap) 
  • Tray or towel to catch any water spills 

 

Directions: 

Step 1: Crumple up a piece of paper and gently open it most of the way. It should still show ridges (high points) and valleys (low points.)

Step 2: Choose one of the ridges and color the whole ridgeline with a washable marker. Use lots of ink! (It’s easier if you use the flat side of the marker.)

 

Step 3: Place the paper on the towel or tray

Step 4: Use the dropper to pour water onto the peak, simulating a rainstorm.

Step 5: Repeat this experiment with more ridges on your crumpled paper.

The colored water is following the path of the watershed! 


 

The Science of Paper Mountains 

    • Watersheds are parts of land, like mountains, that drain rain water and snow melt into rivers and lakes. This water can carry particles from the land into big bodies of water. 
    • Marker ink moves with the water similarly to surface particles that are carried through a watershed. 
    • Surface waste like trash on streets, exposed soil from landslides or construction, or pollution from mines or farms, is picked up by rainwater and carried to the closest body of water. ​ 
    • What happens upstream always influences the water quality and processes downstream. 
    • Does your mountain have a dry side? A rain shadow is a dry area of a mountain that is caused by rain falling before the wind can carry it to the other side of the mountain. 

 

Expand on This Activity: 

Ask Your Scientist the Following Questions: 

  • Which direction is the water flowing? 
  • Does height make a difference? 
  • Which parts of the paper stayed dry? 

Keep Experimenting: 

  • If you have one at home, try putting a Monopoly house or similar small object on different parts of the mountain. See how its location affects the house during heavy rain. 
  • Test different heights for your mountain. When you keep the paper more crinkled you have higher peaks, does the water flow differently than if you flatten the paper more?

The Science of AI Art

A picture is worth LESS than a thousand words, and we can prove it! 

Our brand-new OSC Flight Lab workshop, Painting with Pixels, will teach you how to get the most out of image generators that use Artificial Intelligence! 

The Science of AI Generated Art 

What is AI? 

According to IBM, AI, or Artificial Intelligence, “leverages computers and machines to mimic the problem solving and decision-making capabilities of the human mind.” This definition provides a good understanding of the purpose of AI, but it doesn’t really provide a good perspective on just how ubiquitous AI has become in modern society. You likely use AI in one form or another every single day 

  • Nearly every aspect of your smartphones uses AI to give you the best possible user experience, from improvements to your photo quality and filters on your selfie camera, to autogenerated text-message responses.  
  • Navigation systems like Google Maps and Apple maps use AI to optimize routes based on real-time traffic data.  
  • Online shopping and video streaming platforms use AI to make recommendations based on your browsing and purchase history.  
  • Even your modern smart-home appliances use AI to learn user behavior and make automatic adjustments. 
  • And more! 

As it turns out, every AI that has ever existed falls into only one category, called Narrow AI (aka Weak AI). Narrow AI systems are designed to excel at one particular task or set of tasks. 

How does AI generate Art? 

The AI starts with an image that is just pure noise – literal random pixels of random colors. When a prompt gets submitted to the program, it is first sent through an encoder – essentially a translator to make sure the input you give the AI is in a format it can understand. Then, using this translated prompt, it does something called diffusion, a process in which the pixels of the random noise are manipulated to create recognizable shapes over time. 

There has never been an artist on Earth that has made good art without doing a lot of bad practice art first, and the same applies to AI. Every AI needs to go through training to be able to perform the task it’s built for! This concept is the basis of Machine Learning. We train AI that is designed to generate art by progressively feeding the AI noisier and noisier images of different types of objects with the goal of having the AI successfully denoise those images into something that is recognizable as the original image. The images that it successfully creates get fed back into the data it’s trained on, the images that it fails on get thrown out, and this process is repeated thousands of times until the AI is sufficiently trained.

You can make AI art of your own at home! 

Things you’ll need: 

  • A computer or smartphone with internet access 
  • Adult supervision 

Directions: 

Step 1: Open an internet browser, navigate to the Bing Image Creator, and log in. 

Step 2:Next, think about the image you want to create and come up with a prompt using the Perfect Prompt Formula found below. 

Step 3:Type your prompt into the Bing Image Creator and submit.  

Step 4:Wait while the image generates and enjoy! 

The Perfect Prompt Formula: 

Coming up with a creative prompt for your image generator can be hard, but using the following four ideas in your prompt can help you take advantage of the AI’s capabilities and make better art! 

The best prompts on average have about 40 words and follow this structure: 

“A __[Perspective]__ view of a _ [Description of Subject]__ in the style of __ [Stylization]__, background is __ [Description of Background]__, feelings of __ [Emotion]__.” 

We always want our art to evoke some sort of emotion in the viewer. If you look at a piece of art and feel neutral, that is likely an ineffective piece of art. You can subtly inject colors, shapes, themes, and emotion into your art by putting the keywords "feelings of” in your prompt. Sticking to the standard emotions (i.e., sad, happy, angry) often leads makes the AI just giving everything faces, which may or may not be what you want, so feel free to get abstract with this.

Popsicle Catapult

Use a simple machine to turn potential energy into kinetic energy. 

A simple machine is a device that allows people to do more work with less energy. It specifically applies to making things move and works by using physics to its advantage. 

When an object is moving, it has kinetic energy. ​​For example, as a ball rolls down a hill, its kinetic energy increases. Potential energy is energy that results from your position. ​If you start from the bottom of the mountain and climb up, the potential energy at the bottom of the mountain will be zero, while it will be a lot at the top of the mountain. ​As you climb the mountain, you gain potential energy. 

A catapult combines these two concepts to launch heavy objects long distances. The catapult you’ll be making today is much smaller than a real one but works exactly the same way.

Materials you will need: 

  • Popsicle sticks 
  • Rubber bands 
  • A bottle cap 
  • Glue (hot glue works best) 
  • Pompom balls 

 

Directions: 

Step 1: Glue the bottle cap onto one end of one of the popsicle sticks, leaving a bit of space above the cap. Let the glue dry.

Step 2: Stack 5 popsicle sticks on top of each other. ​

Step 3: Put the popsicle stick with the bottle cap on it perpendicularly – i.e., so it makes a cross – between first and second stick and another one between last and second to last. Leave ¾ of the stick on the other side of the stack.​

 

Step 4: Tie rubber bands on both sides of the stack of sticks to hold it together.

Step 5: Tie the two perpendicular sticks together with a rubber band.

Step 6: Put the pompom ball into the bottle cap.​

Step 7: Push down on the part of the stick behind the bottle cap and releaseWatch the pompom ball fly!


 

The Science of Popsicle Stick Catapult 

  • When you push the stick with the ball down, you are putting potential energy into the ball. ​ 
  • When you release the stick, the potential energy in the ball turns into kinetic energy. ​ 
  • The ball doesn’t go forever because it eventually loses kinetic energy due to the force of gravity. 

Baking Soda Eruption

What’s causing this chemical reaction? 

Try this experiment at home and learn what causes a chemical reaction! A chemical reaction is when one or more substances react to form an entirely new substance with different properties.  

There are 5 signs that a chemical reaction has occurred. These signs are easy to remember…just think about F.A.R.T.S. To identify whether a chemical reaction has occurred, at least one of these 5 changes: 

  • Fizzes: Did the reaction produce bubbles or gas?  
  • Aroma: Did the reaction produce a smell?  
  • Re-color: Did the reaction produce a new color? 
  • Temperature: Did the reaction produce a temperature change or release light?  
  • New Substance: Did the reaction produce a new substance like water or a solid? 

Ready to make your own? Follow the written steps below! 

Materials you will need:

  • Vinegar 
  • Baking soda 
  • Any container (an empty plastic water bottle or small bowl works best) 
  • A tray or something to catch the mess 

Directions:

Step 1:

Pour some baking soda into the container (you don't need a lot)

Step 2:

Carefully pour some vinegar onto the baking soda and watch it fizz. You can pour more vinegar to make it erupt again until all the baking soda has dissolved. 

 

Step 3:

Clean up, and if you want, try again.

The Science of Baking Soda and Vinegar

  • Mixing vinegar and baking soda causes an acid-base reaction that releases carbon dioxide. 
  • The chemical equation looks like this:  NaHCO3(s) + CH3COOH(l) → CO2(g) + H2O(l) + Na+(aq) + CH3COO(aq) 
  • This is an example of an acid-base neutralization reaction, where the reaction forms water and a salt as products. 

Expand on This Activity:

  • Ask Your Scientist the Following Questions: 
    • Which of the changes from F.A.R.T.S. did you notice in the reaction? 
    • What else produces carbon dioxide (CO2)? 
  • Keep Experimenting: 
    • If you have food coloring, you can add a few drops to your baking soda before you pour the vinegar to get a colorful eruption. 
    • You often see this reaction used to demonstrate a volcano erupting. Can you make a volcano out of things you have at home? You could use clay, papier mache, you can even make one outside out of dirt (just watch out for ants!)

Mummy Sock Puppets

BOO! It's Spooky Season, and we're celebrating with DIY mummy sock puppets!

Mummies aren't just a great costume for Halloween night. Mummification was a 70-day process of preserving the bodies of pharaohs, members of nobility, and even animals. This process has allowed us to know what these great individuals looked like 3,000 years ago and to understand the preservation of human bodies.

Research shows that Egyptians began the processes of mummification around 2600 BCE. This practice endured for well over 2,000 years, continuing into the Roman Period. However, the quality of mummification someone received was dependent upon the price paid. Pharaohs such as Tutankhamen and others were prepared with the utmost attention to detail, laid to rest with treasured items.

Chromatography Experiment for Kids

What pigments are in different types of black markers? 

Try this Chromatography experiment and watch as ink breaks down into different colors! 

Chromatography is a really useful technique for chemists, helpful in everything from identifying biological materials to finding clues at crime scenes. Chromatography separates the parts of a mixture based on whether they like to stick to the paper, or if they like to travel with the liquid. 

Ready to try it out? Follow the written steps below! 


Materials you will need: 

  • Black Sharpie marker 
  • Black Crayola marker 
  • Black Expo marker 
  • Isopropyl (rubbing) alcohol 
  • Shallow bowl (this will get marker on it) 

 

Directions: 

Step 1: Rip your coffee filter into three pieces. 

Step 2: At the top of each piece label them. S for Sharpie, E for Expo, and C for Crayola. 

Step 3:Use the marker that matches the letter to make a thick dark mark at the bottom of each piece. 

Step 4:Pour a little bit of alcohol into the bottom of the bowl. 

Step 5:Place the tips of each of the three filter pieces in the bowl so that they are touching the alcohol. It will take a little time, but you should start to see the ink move up the filters. 

The Science of Chromatography 

  • Alcohol acts as a solvent and dissolves the chemicals that make color in markers. The chemicals that dissolve best will move further up the filter. 
  • Sharpies are alcohol based, Crayola washable markers are water based, and Expo markers are alcohol based if they’re dry erase and water based if they’re wet erase.  
  • The alcohol based markers will dissolve better in the rubbing alcohol because it is the main ingredient in the ink.

Can You Hear Me Now? Learn to Make a DIY Cup Phone

Can you hear me now? Learn how to make a DIY Cup Phone!

How do phones allow us to talk to people who are so far away? We can find out by making a DIY cup phone using things you might have around the house. 

Telephones turn sound waves into electricity that can be sent using cables. Once the sound electricity reaches you, magnets are used to convert the electrical signals back into sound waves. The sound vibrates the air around it, so you can hear what the person on the other end of the line is saying. 

Ready to make your own? Follow the written steps below!

Materials you will need: 

  • 2 Styrofoam or paper cups
  • Twine or other string
  • Scissors
  • Markers (these are optional!)

Directions

Step 1: Use the scissors to poke a hole in the bottom of each cup.

Step 2: String a piece of twine between the cups by pushing each end of the string inside the holes you just made. Use a long piece of string to help the sound travel farther.

Step 3: Tie a knot in the end of the string inside the cups to keep the cups from falling off.

Step 4: Feel free to decorate your cups with markers if you want, but there's nothing wrong with keeping them plain!

Step 5: To use the phone, all you have to do is talk into the cup while someone else holds the other cup to their ear. Make sure to keep the string tight; if the string is sagging, the sound won't travel effectively!

The Science of Cup & String Phones

  • You may have heard that sound travels - but how?
  • Sound is made up of waves that we can hear. These sound waves are formed by objects vibrating, or shaking back and forth very quickly. 
  • Sound travels through air, water, and solid objects as vibration. 
  • The sound of your voice vibrates the cup, which cases the string to vibrate, too, as sound travels down it. 
  • Our ears collect the sound vibration, where nerves send them to our brain. 
  • Our brains process the signals, and then we hear the sound!

Civil Engineering Experiment for Kids

Build curiosity with a hands-on civil engineering experiment for kids

A civil engineer uses math, physics, and design to create large structures like buildings, roads, and bridges. Some shapes hold up better against different types of pressure than others. ​​For example, some stand very well against wind, while others hold up against the side-to-side shaking of an earthquake. ​​

In this civil engineering experiment, kids of all ages can put on their thinking caps and hard hats and see if they can design a structure to withstand the forces of nature.

Can YOU figure out which shape works best for which situation? 


 

Materials:

  • Dominoes 
  • Tray or other platform to build on 
  • Desk fan 
  • Weights or something small and heavy
materials needed for civil engineering experiment for kids

 

Step 1:

Build 3 shapes: Start by constructing 3 of the most common architectural shapes, an arch, a pyramid, and a cube. 

  • The arch should include an opening in a structure that is curved on top and designed to distribute weight. 
  • In architecture, a pyramid is a monumental structure having a rectangular base and four sloping triangular (or sometimes trapezoidal) sides meeting at an apex or truncated to form a platform.
  • Your cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges. 
example of popular shapes used in cicil engineering made out of dominos

Step 2:

Test your shapes!

Now we’ll test each structure against different conditions! 

  1. Test each structure – the arch, the pyramid, and the cube – by placing a weight on top of it.  Do they all hold up under the weight? 
  2. Remove the weights from the structures.  Test each structure by using the fan to force wind against the sides of them.  Do they stand up against the wind? 
  3. Make sure all three structures are on the tray. Using your hands, gently shake the tray side-to-side on the table.  Do the structures stay together and pass the test? 
Testing civil engineering experiment #1 with weight
Testing civil engineering experiment #2 with wind
Testing civil engineering experiment #3 with motion

Step 3:

Analyze the results and create some more or stronger shapes! 

Let's take a look at the science behind these shapes and the forces behind them. 

Gravity is the force that pulls things towards the center of the Earth. In doing so, it holds us down on the ground. Certain areas around the world get a lot of wind.  Wind exerts a lateral force on the sides of buildings, pushing against them. One of the hardest places to build cities is in areas with earthquakes. Earthquakes cause the buildings to move side-to-side. ​ 

Now that you've gone through your first round of testing, here are some fun questions to ask your kids about their civil engineering experiments:

  • Which shape worked best against each natural condition? 
  • Where in the world would you find these structures? 
  • Where would you build these structures? 

As you head back to the drawing board, what have you learned, and what can you improve?

  • Does the size of the structure matter? If you have enough dominoes, try scaling them up by making each one 2 or 3 times bigger. 
  • How about the intensity of the conditions? Try putting more weights, increasing wind speed, and shaking the tray more.

The Science of Pancakes

The science of Flipping Pancakes

Pancakes are a common staple at the breakfast table, whether you’re at home in your PJs or drinking coffee at a diner, and it’s not hard to see why: they’re fluffy, light yet filling, and typically covered in delicious syrup. It’s designed to be comforting cuisine! They might be simple and quick to make, but there’s a lot of chemical science at work that’s easy to miss with your standard sleepy-morning eyes, so we’re going to examine the major steps along the way, from batter consistency to the right color. Let’s dive in to the science of flipping pancakes!

Naturally, the first step when making pancakes is to prepare your batter.

You can create it by either combining dry and wet ingredients like flour and eggs, or by using a pancake mix from your local store, which we’ll be looking at today. Pancake mix will take less time overall than measuring and combining all the other materials since they’re blended already, and contains dehydrated fats like powdered butter, egg powder, and buttermilk. Dehydrating fats, or drying as much moisture out as possible, prevents bacteria, yeast, and mold from growing and ensures the mix stays fresh for long periods. When we add a liquid like water or milk to it, it rehydrates the fats and produces the batter substance we’re looking for.

Before adding the liquid, your bowl contains plenty of dry ingredients and each one has its own role to play. The first ingredient is commonly used in the kitchen: flour. Flour is a powder ground from types of grains. One of these flours, wheat flour, contains two types of proteins that link together and make gluten. 

So what's happening? 

The natural chemical leavening agent we’ll be using is baking soda. This helps pancakes rise up while being fluffy and soft. Baking soda is a base with a high alkaline. When it mixes with an acid or in this case, the buttermilk, it creates bubbles that release a lot of gas.

If you’ve ever combined baking soda and vinegar before then you’ve seen the chemical reaction!

Pancake batter ready for pancakes

Now it’s time to add our liquid to help rehydrate the fats. Box mixes usually call for water, but today we’re going to add milk. Milk will up the fat content of our combination, leading to tender flapjacks with more richness and flavor. Now, you might be wondering what kind of milk to use. 

The liquid helps to activate the baking soda and buttermilk, creating the reaction we just covered. These bubbles will rise as you stir. As this is happening, the CO2 bubbles will be trapped by the gluten in the batter when your pancake solidifies, leading to fluffiness! Avoid mixing the ingredients too much though. This can overwork the gluten formation and leave you with tough pancakes. You’re looking for a mixture that’s still lumpy yet blended.

Now that we’ve added our milk, it’s going to rehydrate it so the fat properties can take effect!

When you mix flour with eggs and liquid, the gluten molecules get more flexible and bind to each other to form networks, or nets. These nets trap the air from the carbon dioxide gas, causing the pancake to lift and have a chewable texture.

You can think of it like a hot air balloon, with the gluten as the balloon and CO2 as the warm air. As the CO2 rises up, it expands out the gluten netting giving it lift.

Pancake Batter Bubbling

Let's get cookin'! 

Now that we have our dry and liquid ingredients together, it’s time to get started! There’s a huge variety of ways to cook these cakes, but for this post we’ll be using a nonstick griddle pan. A nonstick surface is useful so we can flip our cakes without too much adhesion, and a griddle pan evenly distributes heat across the cooking surface so the entire cake is done at the same time. To start, you’ll want to heat the pan on medium heat, but avoid settings higher than this. Too hot would burn our breakfast and too low takes longer to finish! Once the pan is hot enough after a few minutes, take a scoop of batter and pour it in!

Do you see or hear anything when the mix hits the hot pan? You may hear a little bit of a sizzle. This sizzle helps indicate our next step taking place: the Maillard Reaction! This step creates the aroma and golden-brown color on the pancake.

the science of the Maillard Reaction

The Maillard Reaction is a chemical reaction between amino acids in the proteins and the carbon and oxygen atoms from sugars. They all bond together on the molecular level and result in a rich palette of distinct and varied flavors. Basically, the proteins and sugars in the mix transform into new flavors, aromas, and colors from the intense heat of the pan. This reaction is how we get coffee roasts, the crust on a steak, or the color and smell of baked bread!

After about a minute, you’ll see the pancake start to firm up and bubbles appear on top. The pancakes turn from liquid to solid through gelatinization. This is when the molecular bonds of starch molecules start to break down when heat and water are introduced. The starch granules absorb the water, swell up, and burst, which causes the batter to thicken and form. The bubbles on top let you know when it’s time to flip the pancake to the other side. This is the gas being forced out of the pancake batter. Cooking raises the temperature and increases the pressure of dissolved carbon dioxide. Bubbles form and rise as the volume of CO2 increases and the capacity of the batter firms up. Once the bubbles pop and release gas, you’re good to flip!

Browning Pancakes

You’ll let it cook for about a minute on the other side. It’ll take less time since there’s already heat in the pancake. Once you get the golden-brown crust you want, take it off the heat and onto your plate! Since you’ll have plenty of remaining batter, you might as well make more. Even as you get low on batter, you can still eat delicious tiny flapjacks! When it’s all ready, serve it up and add your favorite topping. Maple syrup, whipped cream, loose berries, chocolate chips…whatever your heart desires! As we can see, there’s a lot of science that can go into serving up the simple flapjack.
