If you are planning or are in the middle of an animal science homeschool curriculum you are going to get a lot of great questions. Also, you’ll love more ideas on my Oceans Unit Study and Lapbook.

 A fun way to answer them is by adding in some simple hands-on ideas.

My favorite part of any study is including lots of fun hands-on ideas that help a child easily understand a concept.

With that in mind, I have some of the best activities to answer animal science questions.

The first question we are going to answer that goes along with our experiment today is what are gills.

How do Fish Breathe Underwater Fun Activity & Animal Science Homeschool Curriculum

Just like we do, fish need to take in oxygen and expel carbon dioxide to survive.

But they do not have lungs, they have gills. 

Gills are branching organs that are located on both sides of the fish’s head that have a lot of small blood vessels called capillaries.

What Are Gills

Gills work as pumps to move the water while they absorb oxygen and move out carbon dioxide.

The part that you can see on the exterior of the fish is not the gills, rather they are a “gill cover” called opercula.

Watch How Do Fish Breathe Underwater on YouTube for a great video explanation of this process.

What Other Animals Use Gills To Breathe

Mostly fish crabs and mollusks also use their gills to breathe. Larvae like tadpoles and dragonfly larvae use gills in the water at first where they start.

There are many fantastic and inexpensive experiments out there that let your child get deeper involved in the learning process rather than just being read to.

How do Fish Breathe Underwater Fun Activity & Animal Science Homeschool Curriculum

They can help answer questions kids might not even have asked yet or ones you may not be quite sure how to answer yourself.

Animal Science Questions Asked And Answered

For example, look at these questions below.

  • Why do birds fly in a V?
  • How do penguins stay dry?
  • Why do Cat’s Eyes Glow?
  • How do sharks float?
  • What is the difference between warm-blooded vs. cold-blooded?
  • How does a duck stay dry in the water?
  • Why Don’t Frogs Freeze?
  • Why are birds’ beaks shaped differently?
  • Finally, how do fish breathe underwater. We will answer this one further down below with a hands-on experiment.

These are all fantastic ways to teach or learn as a supplement to your box curriculum or used as your very own DIY animal science homeschool curriculum.

Next, look at some of my very favorite books and resources for animal science that help children answer many questions.

The Science of Animals: From molluscs to mammals

DK's elegant new introduction to wild animals is packed with dramatic photography that celebrates their beauty. Crystal-clear diagrams then explain how animals work and describe how they are adapted to do different things and to survive in different environments. The unique nose-to-tail approach, with chapters on different body parts, allows you to focus in on the beauty of the antenna of a moth, the flight feathers of a parrot, or the feeding tentacles of a jellyfish. The Science of Animals also explores how we have depicted animals in art throughout the ages, from zoological drawings that recorded new discoveries to great
paintings inspired by a deep connection to the natural world. With fascinating stories, such as how animals communicate, defend their territories, and attract mates, The Science of Animals offers an engaging introduction to the extraordinary diversity of the animal kingdom.

Finally, how do fish and other animals with gills breath underwater.

How Do Fish and Other Animals with Gills Breathe Underwater Activity

This experiment helps children understand the process of how fish, crabs, and mollusks breathe with gills rather than with lungs underwater. 

Note: The coffee represents the oxygen in the water, the filter the gills, and the water is fresh or salt water the fish takes in.

You will need:

  • 2 glasses or bowls
  • Water
  • Ground Coffee or Dirt
  • Coffee filter
  • Rubber band
How do Fish Breathe Underwater Fun Activity & Animal Science Homeschool Curriculum

First, begin by explaining that the water is ocean water, the coffee is the oxygen in the water, and the filter is the fish’s gills.

Draw gills in the center of your coffee filter to help with the visual.

How do Fish Breathe Underwater Fun Activity & Animal Science Homeschool Curriculum

Place a cup or so of water into a container.

Stir in 1-2 Tablespoons of coffee/dirt allowing the color to absorb somewhat.

How do Fish Breathe Underwater Fun Activity & Animal Science Homeschool Curriculum

Place the coffee filter on top of the second clear container and secure it with a rubber band.

Press it down a bit in the middle so it has a dip in the center to hold the water as it is poured through.

How do Fish Breathe Underwater Fun Activity & Animal Science Homeschool Curriculum

Carefully pour coffee and water through the filter. 

How do Fish Breathe Underwater Fun Activity & Animal Science Homeschool Curriculum

Watch as the filter “gills” traps the coffee “oxygen” as the water passes through them but the grounds ”carbon dioxide” is filtered out.

How do Fish Breathe Underwater Fun Activity & Animal Science Homeschool Curriculum

Show your child how the filter/gills allowed what was needed through and the rest was filtered out (grounds/carbon dioxide).

It is easy to see in this demonstration because now the water has turned brown.
