Science @ Home: Coral Reefs (Ages 4-8)
Many of the ocean’s critters grow up on coral reefs, so it’s the perfect place for mini marine biologists ages 4–8 to get their fins wet.
Coral reefs are home to all the colors of the rainbow—and 25% of all fish species in the sea. From microscopic baby corals to mega-sized sea turtles, there’s room for everyone on the reef. Enjoy a week under the waves with science crafts, activities, coloring, and more.
Please note: While Science @ Home activities are designed to be conducted by kids, some little ones might need adult help with reading instructions and preparing crafts.
Day 1: Welcome to the reef!
Water you waiting for? The reef is ready to explore! Today you’ll get to know these incredible marine ecosystems through five hands-on activities. (30-45 minutes)

Coral up close (specimen)
Well, now you know why they call it “brain coral”! Take a closer look at this 3D coral specimen by zooming, spinning, and rotating it with your mouse or your fingers. The skeleton of a once-living coral, this specimen is now part of the Academy’s natural history collections, serving as a resource for scientists and students all over the world.
As you investigate the specimen, think about the four questions below. Share your answers with a friend or family member or just think in your head.
- What do you notice about the coral skeleton?
- How do you think the coral might look different if it were alive?
- Do you think coral is an animal, plant, rock, or something else?
- Below the specimen is information about it. Can you figure out where or when it was collected?

Day 2: Home on the reef
Home is where the anemone is…at least for a clownfish. Today you’ll visit a variety of ocean habitats and learn why there’s no place like home—especially for residents of coral reefs. (45-60 minutes)

Hide and sea-k anemone (craft)
Clownfish and sea anemones are coral reefs’ cutest roommates. They also help each other out: Anemones provide shelter to clownfish, and clownfish provide nutrients for anemones. Make your own dynamic undersea duo using paper tubes and coffee filters.

Diver’s-eye view (video)
At 25 feet deep and 212,000 gallons, the Academy’s Philippine Coral Reef habitat is the largest living indoor coral reef on Earth. In this video, see what our divers see as they glide through the warm, crystal-clear water to check up on the reef’s residents.
While you watch this video, think about the three questions below. Share your answers with a friend or family member or just think in your head.
- Do all fish look the same? What are some differences you can see?
- How many colors and patterns can you find?
- Think about the body of water nearest to you. Do you think you would see the same kinds of fish?

Divers on duty (video)
It’s hard work keeping our Phillipine Coral Reef in tip-top shape, but Academy divers rise to the challenge every day, completing important tasks like cleaning windows and introducing new fish into the habitat. (You’ll notice that the divers and fish are moving very fast in the beginning of the video—that’s because we sped the video up to show how long it takes to clean the habitat!)
While you watch this video, think about the three questions below. Share your answers with a friend or family member or just think in your head.
- What do you think it’s like to swim with the fish at the Academy?
- Can you guess how many fish are in the Philippine Coral Reef habitat?
- We sped up the cleaning because it took a really long time! What do you think it’s like to be underwater for a long time?

Relationships on the reef (video)
Dive beneath the ocean waves and explore the unique and diverse relationships found on a coral reef. Some of these relationships, like clownfish and sea anemones, are symbiotic, meaning both animals benefit from being together.
While you watch this video, think about the three questions below. Share your answers with a friend or family member or just think in your head.
- Do you ever cooperate with other humans? What about with a different kind of animal, like a pet?
- Think about someone who has helped you. Have you ever helped them in return?
- Have you ever encountered a parasite on land?
