5 Way To Go Green This Holiday Season

Posted on by

Check out 5 ways you can go green (and save some green) this holiday season! 

'Tis the season of red and green, but how green are you actually being? Americans create 25% more waste from Thanksgiving to New Year’s than any other time of year. That’s an extra 1 million tons of trash per week! Here are a few ways you can go green this holiday season without looking like the Grinch!

That’s a wrap on wrapping paper!

It’s a common misconception that wrapping paper can be recycled simply because it’s paper. However, coated, glittery, and textured paper materials cannot.

When these unrecyclable materials get mixed in with recyclable products, it can result in the whole lot being thrown away. Instead, try using paper materials like newspapers, old maps, comics, or make your own!

Out with the old and in with the new

When you upgrade to new tech, don’t just toss out your old devices, recycle them! A United Nations study reported that 44.7 million tons of e-waste was discarded in 2016, and only 20% of it was disposed of properly. Here are some easy ways you can recycle, or donate and make a difference:

  • Call2Recycle is a nationwide organization that recycles old devices and batteries. You can simply mail in old tech without leaving your house, or enter your zip code to find a convenient location near you!
  • Does your old phone still function? The World Computer Exchange is a nonprofit organization that works to get developing countries into the digital age. They accept everything from computers to graphing calculators.   

Sew what else can I do?

Handmade gifts are a great way to show someone how you feel without creating excess waste. From bath bombs to jewelry making, you can’t go wrong with a personal touch.

Upcycling is another great way to save the planet and a little money. Old board games are a great way to customize a picture frame. Or grab some old clothing and embroider an embellishment.

Last but not leftovers

According to the WorldWatch Institute, Americans generate three times as much food waste between Thanksgiving and New Year’s as we do the rest of the year. Resolve to go green this year, by starting a compost! Are you a local? The City of Orlando will help you get started for free!

Composting is not as difficult or as disgusting as you might think! It can divert up 30% of food waste from a landfill and back into healing the Earth while offering a natural alternative to chemical fertilizers. Here is a simple step-by-step guide to creating your compost starting with the end of your Christmas tree!

Think outside the plastic box

Tired of giving gifts that will be outgrown or outdated in a few months? This holiday season, ditch the plastic packaging and gift an experience.

You can avoid creating excess waste by gifting tickets to movies or events, certificates for chores or date night, gift cards that can be reloaded and re-gifted, or gift a membership to a favorite theme park or science center!

Cool Reindeer Facts You Didn’t Know

Posted on by

Eenie meenie miney doe, how many reindeer facts do you know?

You know Dasher and Dancer and Prancer and Vixen, Comet and Cupid and Donner and Blitzen. But do you recall, the biology of them all? You’ve probably heard this song before, but have you heard the science behind Santa’s fluffy helpers?

A reindeer by any other name...

What exactly is a reindeer? These animals are part of the deer family, or Cervidae, which includes deer, elk, moose, and wapiti. Reindeer are also commonly known as caribou. This classification is primarily based on location, or habitat. Reindeer refers to the domesticated animal, while caribou refers to the wild animal.

Female reindeer are slaying it!

Scientists have observed that male reindeer shed their antlers in early December after mating season, while female reindeer keep their antlers all year. This means that if the reindeer spotted pulling Santa’s sleigh on December 24 have antlers, they must be females, as males would have already shed their antlers.

The real red-nosed reindeer

You may remember Rudolph the Red-Nosed Reindeer, and his shiny schnoz. Scientists say that having a rosy nose is not only possible but common in Santa’s furry friends. Reindeer have 25% more blood vessels in their nose than humans. This helps keep their noses warm, which allows them to warm up the frigid air before they breathe it in. Exposure to extreme cold, or exercise increases blood flow, and with so many extra blood vessels in their noses, they can turn a light rosy color.

Eye on the prize

Reindeer have also adapted to see ultraviolet light. While humans are no strangers to ultraviolet light, we are unable to see it. UV rays are commonly known to cause sunburn or snow blindness by reflecting brightly off of the white snow. Reindeer, however, have adapted the ability to see these wavelengths. This not only protects their eyes but allows them to better see food or other animals camouflaged in the snow.

The cold never bothered them anyway

Why does Santa have a reindeer-drawn sleigh instead of a horse-drawn carriage? Reindeer are native to cold climates like Alaska, Canada, and Scandinavia and have adapted to the cold. A reindeer’s fur is made up of hollow hairs that trap in air and keep them well-insulated. They are also the only animal to have hair completely cover their noses. This helps warm up the cold air they breathe before it reaches their lungs.

So next time you hear the pitter-patter of hooves on your roof, remember it’s no coincidence that Santa uses these gentle giants to pull his sleigh. Reindeer have adapted to weather their frosty environment and help deliver Christmas cheer all over the world!

How Native American Tribes Shaped Purple Martin Birds

Posted on by

 Learn how Native American tribes shaped Purple Martin birds and their nesting habits 

Did you know that Purple Martins famously don't build their own nests? You could almost call them people martins because they depend entirely on human-made nests to raise their chicks. 

It’s been documented that when indigenous peoples would hang out their gourds to dry, Purple Martins started nesting inside them. They left them hanging up in their villages for the birds to live in. To this day, Purple Martins are one of the only bird species to prefer human-made houses over natural ones. Using what we’ve learned about how Native American tribes shaped Purple Martin birds, we can better practice conservation efforts for migratory birds.

 

Disney’s Animals, Science, and Environment department built a specialized Purple Martin house for Orlando Science Center. Our high-rise, park-front condo features 22 different nests for new martin parents to raise their young (and it’s already furnished!) Our house is located in Loch Haven Park, just outside the 4Roots Cafe.

What Native tribes housed Purple Martins?

Martins are migratory birds. They spend the winter and fall in Brazil and make their way to Florida every spring! 

Florida is home to several tribes of Indigenous peoples. Each Native tribe is unique, and their people lived in different regions and spoke different languages.

Using the Native Land App on your Apple or Android device, you can find out what Native Land you currently live on. Orlando Science Center is located on Timucua land!

Learn about some of the most historically documented Native American tribes in Florida!

A map of florida showing Native American tribe territories
*It's important to note that this is not a complete list. Indigenous peoples lived in what is now known as Florida for more than 12,000 years before the time of first contact with Europeans.

The Seminole (Creek) tribes are well known for their beautiful woodcarvings, beadwork, and baskets.

The Choctaw tribes were known for their colorful clothing. The women typically wore multi-colored dresses or wrap-around skirts and the men wore colorful shirts made of woven fibers

The Timucua were known to have more permanent villages than the other tribes. Each family had their own home but the cooking took place in the village and meals were held daily in a central location

The Calusa are considered to be the first "shell collectors." Shells were discarded into large mounds. Unlike other Indian tribes, the Calusa did not make many pottery items

The Jeaga are hunter-gatherers who subsisted mostly on sea turtles and oysters, as well as conch, fish, deer, raccoon, manatee, alligator and shark. They also collected wild plants including coco palms, sea grapes and palmetto berries

The Tequesta used shells and sharks' teeth for a variety of tools. These included hammers, chisels, fishhooks, drinking cups, and spearheads. Sharks' teeth were used to carve out logs to make canoes

The Apalachees played a ball game that was a religious exercise as well as a sport. One village would challenge another to a match, and the two teams would have up to 100 players each. They used a hard clay ball about the size of a golf ball covered with buckskin. Players propelled the ball with their feet toward the goal post which was a pole topped with a stuffed eagle in a nest. They played the ball game in the spring and summer, and dedicated it to the gods of rain and thunder to ensure rain for their crops.

The Miccosukee historically are farming people. Miccosukee women did most of the farming, harvesting crops of corn, beans, and squash. Miccosukee men did most of the hunting and fishing, catching game such as deer, wild turkeys, rabbits, turtles, and alligators. Miccosukee included cornbread, soups, and stews in their meals

The Ais are one of many tribes, consisting of several hundred thousand people that lived in Florida prior to first contact with Ponce de Leon and the Spanish in 1513. The Ais tribes fished using hooks made from the toe bones of deer they had hunted, taking full advantage of the great catches available off the coast of Florida

How to Get Teens Interested in STEM at School

Posted on by

From hands-on experiences to museums and mentors, here are some tips on how to get interested in STEM in school

If you want to nurture your child’s interest in Science, Technology, Engineering, and Mathematics (STEM), it’s important to go beyond the four walls of their classrooms. A report by the National Academies of Sciences, Engineering, and Medicine revealed that only 22 percent of American high school graduates are knowledgeable in these particular subjects. In fact, the chair of the committee stated that students have limited learning experiences that are confined to reading textbooks, passive listening, and memorizing disconnected facts.

That said, the chances are that your teenager probably needs more opportunities if they are to become more interested STEM. So here are some tips that can encourage them to take most interest in STEM subjects:

Show how to apply STEM to real life

It’s hard for your child to gain an interest in STEM if they can’t see why it’s relevant to everyday life. STEM education can be pretty intensive, so the whole process can get a little overwhelming. Thus, it’s important that your child takes a step back and looks at how it is relevant to their day-to-day life.

Digital Learning emphasizes that students must also be given a chance to see the concepts come to life in a real, physical environment. Allowing them to see how robots or even statistical software are developed, which can boost their interest and their confidence in pursuing a career in STEM. The key here is to expose them to experiences that can help them understand its importance.

Provide hands-on learning experiences

Hands-on learning experiences are very important. STEM experiments and projects provide your child the opportunity to witness firsthand how cool STEM is as they get to deep dive into certain fields.

Education design consultant Karen Aronian looked at how chess incorporates math and logic, which allows kids to learn while also enjoying the challenge of playing board games. On the other hand, they can be introduced to electronics through online resources like Upverter, which is a free, web-based printed circuit board (PCB) design tool. Upverter is the educational and student-friendly version similar to the industry standard design platform Altium 365. Both platforms allow users to design, share, and manufacture electronics all in one place. Through these hands-on activities, your teen can gain first-hand experience in these academic fields.

Take them to exhibits and museums

Another great way to encourage an interest in STEM is by visiting exhibits and museums. These centers not only improve their knowledge regarding STEM subjects, but they can also pique their curiosity when it comes to certain subjects.

Orlando Science Center is a staunch advocate of STEM learning through museums and their exhibits. This is an avenue to introduce teens to new and exciting STEM concepts. For instance, the Flight Lab allows visitors to learn more about aviation through virtual reality simulators. 

Held annually at OSC, Otronicon Interactive Tech Convention has created a rich environment for active STEM learning through hands-on exhibits, tech demonstrations, industry-professional-led workshops and panels, gaming competitions, and much more, connecting Central Florida audiences to industry experts and innovative tech that is driving the future.

 

Connect your child to a mentor

The teachers in your teen’s school can be the key to igniting their interest in STEM. By connecting them to a mentor, it will enable them to receive career advice which will help them map out a career path in STEM. This is even more significant for girls who want to join male-dominated fields, such as engineering and computer science.

If your child has a good role model in their school, encourage your teen to interact and learn more from this specific teacher. STEM after school clubs are a great place to meet good mentors. They provide them with an opportunity to talk about their interests with like-minded students. This allows their ideas to flourish, further encouraging them to delve deeper with regard to STEM topics.

At the end of the day, your teen will be more interested in STEM if they have opportunities to learn more about the subjects they are interested in. As a parent, you provide support by broadening their exposure to professionals and real-life STEM applications.

3D Printing Assistive Technology • How the Maker Movement is Making A Difference

Posted on by

How open-source 3D printing is changing the world of assistive technology

The concept of 3D printing, or Fused Deposition Modeling (FDM) has actually been around since the early 80s thanks to Dr. Hideo Kodama, with the first 3D printer commercially available in 1986. 3D printing became a revolution in the STEM community with use by engineers, inventors, and even medical professionals when a 3D printed kidney was successfully transplanted to a patient in 1999!

As 3D printing technology became more diverse and affordable, it has continued to gain popularity among scientists, makers, and hobbyists alike. From a 3D printed car to a 3D bioprint of Vincent van Gogh’s ear, it seems creativity is the only limit.

 

3D printing also increases accessibility with much success in printing casts for broken bones, prosthetic limbs, even wheelchairs that can be customized and created for a fraction of the cost. These are a cost-effective way to keep up with a child as they grow, or damage their current one in the act of being a kid.

Limbitless Solutions, a UCF-based nonprofit organization, dedicated to empowering children through expressive bionic arms at no cost to their families surprises 7-year-old with 3D printed Iron Man prosthetic arm presented by Iron Man himself, a.k.a. Robert Downey Jr.

While it seems almost anything can be 3D printed, it must first be designed and modeled – a process which is often easier said than done. Even that skill is no match for the triumph of the human spirit. Open-source websites have become popular hubs for professionals and makers to freely share their designs.

Websites such as Thingiverse, e-NABLE, and NIH 3D Print Exchange - COVID-19 Supply Chain Response, not only allow designers to help each other improve their work, but makes affordable technology more accessible.

From 3D modeling to soldering a circuit board, The Hive: A Makerspace Presented by The Isaacs Family is one of OSC’s newer exhibits, that focuses on learning new maker skills, as well as new and creative ways to use them. Whether you’re a tech tycoon, or a happy hobbyist, it’s never a bad idea to add another skill to your metaphorical, or literal, toolbelt.

Can Service Dogs Help STEM Professionals?

Posted on by

Learn how service dogs can help people with disabilities breakdown barriers!

Have you ever seen a person using a service animal? Why do some people have animals that help them complete tasks? 

When most people think of service animals, what probably comes to mind is a person who is blind using a seeing-eye dog, but there are a wide variety of disabilities and medical conditions where a service animal can be used to help people.

People who have disabilities sometimes use service animals, like dogs, to help them complete day-to-day tasks easily. Service dogs are specifically trained to help their owners complete tasks they would not be able to do independently; like open a door, bring them their car keys, and even guide a person who is blind across a street. Some dogs can detect when a person’s heart rate lowers, or when they are showing signs of anxiety from previous trauma. The dogs can alert their owners, and they can then take medications they need, prevent an anxiety attack, or get to a safe space away from people.

Service dogs are “tasked trained” meaning there is a specific task or behavior they have been trained to perform to help their owner. This is what separates them from just your average pet dog. Not every person with a disability needs a service dog, but some people can’t imagine trying to live their life without one!

Sierra Middleton was an animal care intern at Orlando Science Center where she helped to clean enclosures, walk animals outdoors, provide a science learning experience for guests, performed water chemistry testing, and learned how to train exotic animals, accompanied by her loyal service dog, Duke. 

To me, Duke is more than just my service dog - he’s my lifeline in a lot of ways. He means an increased quality of life; helping me with things every day as simple as picking up my dropped phone to as great as alerting me to an impending medical episode.

The many ways I have trained him to help mitigate my disabilities have certainly helped me in more ways than I can count, but in all honesty it was the mere existence of his unconditional love that acted as a light at the end of a long, dark tunnel.

The Americans with Disabilities Act (ADA) was signed into law on July 26, 1990, by President George H.W. Bush. The ADA is one of America's most comprehensive pieces of civil rights legislation that prohibits discrimination and guarantees that people with disabilities have the same opportunities as everyone else to participate in the mainstream of American life -- to enjoy employment opportunities, to purchase goods and services, and to participate in State and local government programs and services.

Soil Science Experiment • How to Demonstrate Soil Erosion

Posted on by

Learn about erosion with this soil science experiment!

Forces of nature like wind and rain shape and reshape Earth’s surface by gradually wearing away, or eroding rocks and soil.

When it rains, water that is not used by plants or dried up by the sun slowly flows through the topsoil downhill into nearby water basins like lakes, rivers, streams, and aquifers. Natural areas like Mangroves, Cypress Swamps, Coral Reefs, and Pinewood Flats act like buffer zones which lessens the harmful effects of natural disasters like tropical storms and hurricanes have on Florida.

In this soil science experiment, you will see how different environments can affect water runoff and soil erosion. 

Materials:

  • 3 plastic bottles
  • 6 cups of soil
  • 1 cup of mulch with some leaf litter
  • 1 square of grass taken from outside. Not the grass pulled out, but a small section removed with a garden spade to be placed inside one of the bottles
  • 1 watering can which will simulate rainfall
  • 3 clear disposable cups
  • 3 pieces of twine that are 12 inches long
  • Scissors or a box cutter
  • Hole puncher (optional)

 

Let's get started! 

  1. Begin by cutting off one side of all 3 of the plastic bottles. (Cut the bottles vertically in half from top to bottom.)
  2. Place the bottles on their sides and fill each one with two cups of soil.
  3. In one bottle, add the 1 cup of mulch and leaf litter and pack it down.
  4. In the second bottle, add the grass that was collected and pack it down.
  5. Lay the bottles horizontally with the mouth of the bottle hanging over the edge of a table.
  6. Make 2 holes at the top on each side of the “catch-cups” using the hole puncher or you can use the scissors or box cutter.
  7. Pull the twine through the holes and tie them to make handles for the cups.
  8. Attach one cup with twine to each one of the bottles so that each one has a cup hanging from the mouth over the end of the table (see photo).
  9. Now the fun part! Use your watering can to simulate a rainstorm by watering each of the soil science bottles
  10. Make observations and record your findings about which model held the most rainwater, and what the water looks like in the catch cups.
