National Hummingbird Day

Happy National Hummingbird Day! 

Wildlife — Conservation — Awareness

National Hummingbird Day is celebrated each year on the first Saturday in September. Hummingbirds are incredibly adapted pollinators, which makes them very important to their ecosystems. Three quarters of the world's flowers depend on pollinators like hummingbirds, insects, and bats for pollination! Join us to learn more about these incredible, tiny birds, how we can support our fluttering friends, and even make your own Hummingbird Feeder!

Fun Facts About Hummingbirds

The most common hummingbird seen in Florida is the ruby-throated hummingbird, which weighs approximately 1/4 ounce. That's as light as a penny!

Hummingbirds belong to the avian family Trochilidae. Trochilines often have iridescent feathers of metallic red, orange, green and blue. They are the only birds that can truly hover!

Hummingbirds use wicking action to draw nectar into their mouths using their long, narrow bills and tongues.

  • Of the 338 known hummingbird species, all can be found exclusively in the Americas; 16 are found in the United States; and 3 occur in Florida!
  • Hummingbirds can beat their wings up to 200 times per second, creating the humming sound that gave them their name.
  • Hummingbirds can suspend their bodies in midair, fly backwards, upwards, and even upside-down, much like helicopters.
  • Most hummingbirds will pollinate and feed from a wide variety of flowers, but they are mostly attracted to plants that produce:
    • Large amounts of nectar with substantial sugar content to sustain their high-speed habits.
    • Red and orange flowers or bracts.
    • Flowers that are long and tubular and point downward.
    • Long stamen that deposit pollen on the hummingbird's forehead.

What We Can Do to Help Hummingbirds

  • More than half of the hummingbird species live in the tropics, so purchasing shade-grown coffee is an effective way to protect hummingbird habitats.
  • In Florida, hummingbirds nest spring through summer, so having lots of tubular flowering plants and hummingbird feeders is helpful!
  • When shopping for a hummingbird feeder, choose one with red fixtures, multiple feeding stations, and a means to monitor nectar levels. It’s best to clean your feeder once a week with hot water.
  • Petroleum jelly is an environmentally friendly way to deter pests such as ants from invading your feeder!
  • Hummingbird food sources can be implemented easily by providing sugar water in hummingbird feeders and planting flowers, such as:
    • Bottlebrush (Callistemon citrinus and Callistemon viminalis)
    • Cigar Flower (Russelia equisetiformis)
    • Columbine (Aquilegia canadensis)
    • Coral Bean (Erythrina herbacea)
    • Coral Honeysuckle (Lonicera sempervirens)
    • Firebush (Hamelia patens)
    • Firecracker plant (Russelia equisetiformis)
    • Firespike (Odontonema cuspidatum)
    • Horsemint (Monarda punctata)
    • Red Buckeye (Aesculus pavia)
    • Scarlet Salvia (Salvia coccinea)
    • Shrimp plant (Justicia brandegeana)
    • Soap aloe (Aloe maculata)
    • Starburst Clerodendrum (Clerodendrum quadriloculare)
    • Turk’s Cap Mallow (Malvaviscus penduliflorus and Malvaviscus arboreus)
    • Swamp mallow (Hibiscus coccineus)

Make Your Own Hummingbird Feeder

Supplies: 

  • 3 plastic bottles, empty with labels removed
  • 3 yellow drinking straws with a bend
  • 3 disposable plastic red plates
  • Electric drill
  • Hole punch
  • 12 gauge craft wire
  • Rubber band
  • White glue
  • Scissors

Step 1: Trace and cut out a flower shape on each red plate.

Step 2: Use the drill to create a hole in the top of each bottle cap that is just wide enough for a straw to fit through.

Step 3: Punch a hole in the center of each red plastic flower and thread each one onto the end of a straw. Insert the straw into the cap of a bottle and seal with white glue. Make sure the bend of the straw is just outside the cap opening so the straw bends at an angle as it comes out of the bottle. This is where the hummingbird will drink from!

Step 4: Arrange the flower so it is at the end of the staw's bend to attract the hummingbirds. Glue in place. (You'll need to remove the cap to add nectar to the bottles, so keep that in mind as you apply glue!). 

Step 5: Allow to dry overnight.

Step 6: Once set, wrap the wire around the neck of a bottle, then pull it up to create a hanger for the bottle.

Step 7: You can attach all three of your bottles together in a pyramid shape to create a larger feeding station! Use the rubber band to go around the top and hold the bottles together.

Make Your Own Hummingbird Nectar

During hot, dry weather, when hummingbirds risk dehydration, it's best to make your nectar mixture no stronger than a quarter cup of sugar per cut of water.

Recipe:

  • 1 cup hot water
  • 1/4 cup white table sugar

Steps:

  1. Mix sugar with hot water until completely dissolved.
  2. Let cool to room temperature.
  3. Add mixture to hummingbird feeder!

A Letter from an OSC Events Intern

A Letter From An Events Intern

In late 2021, I was searching for an internship position in Central Florida to gain more experience in the events industry. After contacting countless businesses and companies, the Orlando Science Center’s Meetings and Events Department reached out to me to offer an internship position with their team. Reflecting on all the events I helped facilitate and the in-depth knowledge I have gained as an events intern, I am confident when I say that interning at the Orlando Science Center is one of the greatest decisions I have made.

The events industry is vast. It ranges from corporate meetings to weddings to trade shows. Although the Orlando Science Center mostly hosts weddings, it does bring in many different types of events including fundraisers, meetings, and corporate galas, just to name a few. As a meetings and events intern, I have learned many tips and tricks as well as best practices that will undoubtedly prove to be beneficial in my professional endeavors, no matter what sector of the events industry I pursue.

This internship opportunity has not only been skillfully enriching, it has also been outright fun. All events and weddings are different, which is why I love them. Every time I come in for my shifts, there is always something new to do. For instance, I once found myself building a couple’s Harry Potter Lego set for their wedding day decorations! If you enjoy hands-on activities and inputting your own creative touch, you will love interning at the Orlando Science Center.

As part of the Meetings and Events Department, I have gained extensive event production abilities by creating contracts, submitting work orders, developing event production schedules, and so much more. This internship also pushes you to develop your interpersonal skills with all types of personnel including staff from other departments, your supervisors, and event vendors. Talking about vendors, this position has helped me become more familiar with our local Central Florida vendors and distinguish who are the top service providers in the City Beautiful.

Vendors are crucial in all sectors of the event industry so acquainting myself with experienced businesses and being able to distinguish quality service will definitely be fruitful in the long run. This image below shows MJ from Junction 88, one of the preferred entrainment providers at the Orlando Science Center. He dressed up in Jedi cosplay for a Star Wars-loving couple! As an intern, you truly will be able to differentiate those highly dedicated vendors, like MJ, who go above and beyond.

All in all, putting everything that the Orlando Science Center has taught me into words is simply not possible. You learn how to implement the right lighting for events, how to facilitate vendor load-in and load-out to minimize waiting, what a standard wedding timeline looks like, and overall, how to exceed a client’s expectations by creating the most phenomenal event for them. I would recommend interning with the Orlando Science Center’s Meeting and Events Department in a heartbeat because I am confident that you will love it as much as I did.

Interested in joining the OSC team?

We are looking for highly passionate and dedicated people to help support our mission of inspiring science learning for life. Orlando Science Center offers a variety of employment opportunities which vary from entry level positions to supervisory and management roles. 

Local Teen Scientists Compete to Save the World at Dr. Nelson Ying Science Competition

From fighting climate change to saving bees, local teen scientists are changing the world!

To compete in the prestigious Dr. Naleson Ying Science Competition, each entrant must be a Central Florida high school student and pursue a research project that has the ultimate goal of benefiting humanity. This year, each finalist’s research had an environmental focus, from cleaning up microplastics in the oceans to monitoring methane emissions to combat climate change to protecting and sustaining bee populations. In addition to the grand prize winner, each finalist received $500 to continue their research.

Ella Pilacek, a sophomore at Oviedo High School in Seminole County, has won the top prize in the prestigious Dr. Nelson Ying Science Competition at Orlando Science Center. Her research project, which was focused on proving that bees could be encouraged by Pavlovian conditioning to pollinate specific plant species, won a scholarship of $5,000, a $1,000 award for her science teacher, and an additional $1,000 for their school.

Pilacek was named winner during an awards ceremony at the Historic Dubsdread Ballroom on Sunday, April 24, following a day of presenting her findings to judges on Saturday, April 23, at the Science Center. This year, the competition and the awards ceremony were held in person for the first time since 2019. The previous two years, they had been conducted virtually due to the pandemic. Since 1999, Dr. Nelson Ying — local scientist, entrepreneur and philanthropist — has partnered with Orlando Science Center to celebrate outstanding student scientists through his creation and sponsorship of this competition.

Honeybees are extremely important to our natural ecosystem due to their role as an essential species of pollinator. This project involved creating a probiotic treatment mixture made from lactic acid bacteria and a type of machine learning technology to help honeybees fight off a harmful gut parasite.

Atreya Manaswi, Orlando Science High School, Orange County

Hive beetles are an invasive pest and a danger to bees, a very important pollinator species. This project built on his previous research that suggested beer was extremely effective for attracting and trapping small hive beetles. He investigated the attractiveness of a volatile oil blend that was fabricated by isolating key odor compounds found in beer. Trapping small hive beetles can ensure protection and survival of beehives.

Atreya Manaswi - OSC Ying Competition Finalist holding trophy

Pilacek’s winning research supported using Pavlovian conditioning with bees so they would follow specific scents to plants that aren’t their usual food sources. The next step in her research will be to test it in the field, using these scents to attract bees to endangered plant species, which would encourage pollination and combat habitat fragmentation. Previous winners of the Dr. Nelson Ying Science Competition have gone on to continue their research at top universities, compete in national science competitions and ultimately pursue exciting STEM careers, including positions at NASA’s Jet Propulsion Laboratory.

Ying is a longtime supporter of Orlando Science Center. After sponsoring numerous exhibits and serving on the Science Center’s board of trustees, he decided to invest in the long-term impact of our mission to inspire science learning for life. In 1999, he and volunteer Fred Curtis launched the Dr. Ying Science Competition with Orlando Science Center to celebrate and inspire exemplary science students to use their expertise to address real-world problems. Ying’s son, Nelson Jr., now oversees the competition with Curtis in collaboration with Orlando Science Center. They continue to engage and mentor young people to leverage their passion for science to make the world a better place.

Pilots & Patients • The Complicated History of the Tuskegee Institute

The Tuskegee Institute Study and its Health Impacts Today

Standing outside Orlando Science Center in Loch Haven Park stands the Red Tails Monument — a 12-foot bronze spire leading up to four P-51 Mustang aircrafts in the “missing man” formation. This monument to the “Red Tail Angels” of the Tuskegee Airmen pays tribute to a group of Black pilots who graduated from the Tuskegee Institute.

However, not everything about the Tuskegee Institute is a cause for celebration. In fact, for the 40-year span between 1932 and 1972, the university was home to a horrific experiment whose impacts are still felt even today.

The Tuskegee Experiment, as it is commonly known, sought to study the long-term effects of untreated syphilis, a disease caused by the bacterium Treponema pallidum. Over the course of the investigation, 399 African-American men with latent syphilis (that is to say, they were asymptomatic but had bacteria present in their bodies) were observed, along with 201 healthy men in a control group.

Signs stating “YOU MAY FEEL WELL AND STILL HAVE BAD BLOOD. COME AND BRING ALL YOUR FAMILY” were posted in Macon County, Alabama — the area around the Tuskegee Institute — in the fall of 1932. As you may recall from history class, this was deep in the middle of the Great Depression. Many folks in this part of the country were sharecroppers, tending farmland in exchange for a portion of the food that was grown. With the promise of a free medical exam and a meal to go with it, lots of people understandably took the signs up on their offer.

What the study designers neglected to do was tell participants that they had syphilis. That’s right—in a study of how a disease affects a human long-term, the human participants were never told they had the disease in the first place! Most egregiously, penicillin was a widely-accepted, widely-available standard treatment for syphilis by 1947. The study leaders did not allow the patients enrolled to receive this treatment, instead choosing to allow them to continue to be sick for almost 25 more years. Out of 600 initial participants, only 74 were alive at the time the study ended.

There was public outrage after the story of the Tuskegee experiment came out in 1972. Congress responded to the outcry and passed the National Research Act in 1974. This law mandated that study participants give “informed consent,” meaning they must know what they are being studied for, and that they be given accurate medical information of their diagnoses and test results.

The effect of this eroded trust in medicine persists even now. There are known racial gaps in access to healthcare and enrollment in medical school. Groups such as the Association of Black Cardiologists (ABC) are working to eliminate these differences in access, with the vision that all people—regardless of race, gender, or other characteristics—should equally benefit from known ways to reduce the occurrence of heart disease.

Unfortunately, public trust in health systems was severely shaken by this news, especially among Black Americans. Studies have shown that there was an over 20% reduction in preventive healthcare by older Black men in the area around Tuskegee.

It is important to remember why we honor February as both Black History Month and American Heart Month. Heart disease claims over 650,000 American lives every year. Due to disparities in our healthcare system, this includes a disproportionate number of people of color, including Black Americans.

The Science of Self-Care

January at the Orlando Science Center is Self-Care Aware Month!

But what does "self-care" mean anyway? We're here to tell you, it's more than just spa days and daily chocolates! 

When you think of self-care, chances are you think of taking daily walks, meditating, reading, playing music, or any other activity that makes you happy. These activities are external to you, meaning they’re things that happen outside of your body. But stress is an internal experience. You feel it inside your body, and it impacts each of us a little bit differently.

Some people might have trouble sleeping, while others might experience scattered thoughts when facing stressful situations. Some people may even have difficulty breathing! So how do we battle these internal feelings of stress?

The scientific answer is to regulate your nervous system. Your nervous system controls everything you do – walking, thinking, feeling, and even breathing. It’s important that any kind of self-care you practice cares for your entire nervous system – both your body and your brain. There are some activities that scientists recommend to help you do this, including mindful breathing, meditation, and progressive muscle relaxation, which involves intentionally relaxing one muscle at a time.

When you make self-care a routine part of your life, research suggests that you can reduce stress and avoid burnout, which is a feeling of emotional, mental, and even physical exhaustion that can be caused by prolonged stress. Tuning into yourself and enhancing your emotional self-awareness through regular self-care is a great way to create balance in your life.

Here's a list of science-based activities to help you practice self-care at home:

  1. Is reading your favorite way to unplug and spend time with yourself? Make yourself an Iridescent Bookmark to help keep your place.
  2. Take your meditation outside, and then tune into your body and your surroundings with this Outdoor Scavenger Hunt.
  3. Do you like to fidget? Give your fingers something to do while you take some mindful time for yourself with these Embroidery Techniques.
  4. In Japanese culture, origami cranes have come to symbolize a sense of peace. Find your inner peace with the Art of Paper Folding.
  5. Practice your progressive muscle relaxation in a warm bath using some Homemade Bath Fizzers.  
  6. Color psychologists study how different colors can impact your mood, creativity, and behavior. Surround yourself with colors that you associate with comfort or happy memories to promote stability and relaxation. Science suggests these might be blues or greens for the majority of people. You can do this with your clothes, your pens and pencils, your water bottle, and more!

Cool Reindeer Facts You Didn’t Know

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.

an imgae comparing the size of reindeer, deer, elk, and moose

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!
