Animals have developed an amazing variety of body plans, behaviors, and strategies in order to succeed in the struggle for survival. Explore topics ranging from regeneration, camouflage, animal migration, how to attract hummingbirds, and more.

M&M Survival Challenge

Science Fair Project Idea

Scientific Method

In the wild there are two types of animals: the hunters and the hunted. A good predator is always on the prowl for fresh prey. What can an animal do to stay off of the menu? Some animals have evolved to use a variety of camouflage tactics so they can fool their predators and increase their chances of survival. In this science project, you will be the hungry predator hunting for M&M® prey. But it may not be as easy as it sounds — some of your prey will be camouflaged. Will they be… Read more

How Much Worm Is a Worm?

Science Fair Project Idea

Scientific Method

Worms are slimy, wiggly, and gross. But did you know that they have many unique abilities? One of the neatest things that worms can do is regenerate, or re-grow, parts of their body. After a piece of a worm is cut off, it can grow back with all of the necessary new parts. How much of a worm can you cut off and still get regeneration? Is one end of the worm better at regenerating than the other? See if you can make heads or tails of this wiggly problem! Read more

Bones and Calcium

Science Fair Project Idea

Scientific Method

Why is your grandmother always wondering if you are drinking enough milk? Our bones are made out of calcium, a mineral found in milk, and drinking milk can lead to strong healthy bones. What about other animals? What are their bones made of? What kind of bones do they have? Are there animals without bones? Are endoskeletons and exoskeletons made out of the same materials? Read more

Pedalism and Movement

Science Fair Project Idea

Scientific Method

Humans are bipedal, which means we walk using two legs. This gave humans an adaptive advantage during the evolution of humankind. Being bipedal gave humans additional speed, balance and flexibility used for walking, hunting or traveling long distances. However, we may have lost the ability to climb or swing in trees like other primates. How much faster can you go when you are bipedal? Have a race with your friends using two legs, and then four legs (use your arms as your 3rd and 4th legs).… Read more

How Much Do Different Pet Species Eat Compared to Each Other?

Science Fair Project Idea

Scientific Method

Are you in charge of feeding your family pet? How much food do you think your pet eats compared to other kinds of pets? After adjusting for your pet's body weight, you might be surprised how it will compare to other kinds of pets. What type of pet do you think will eat the most for its body weight? Read more

Attractants and Repellants

Science Fair Project Idea

Scientific Method

Animals respond to chemical cues in different ways. If an animal turns away from a chemical cue, then that chemical is a repellent. If an animal turns toward a chemical cue, then that chemical is an attractant. Attractants and repellents can be airborne chemicals, chemicals found in food, or chemicals that diffuse through water. One example of an airborne chemical is a pheromone, a chemical signal that is released by one individual to attract another. Moths release pheromones to attract… Read more

The Touch Response

Science Fair Project Idea

Scientific Method

All animals need to respond to changes in their immediate environment. The sensory structures of animals are each made to respond to distinct types of sensory stimuli: touch, taste, sound, light and smell. How are these stimuli received? Different animals have different strategies for receiving stimuli and develop specialized structures for doing so. Antennae, ears, noses, tongues, eyes, eye spots, hairs and bristles are all examples of sensory structures used by different animals to sense… Read more

How Does a Chick Breathe Inside Its Shell?

Science Fair Project Idea

Scientific Method

Have you ever wondered how a chick breathes inside its shell? Every animal needs oxygen to survive, so the chick must get air somehow! Try this science project to discover the answer. Read more

Finding Phyla

Science Fair Project Idea

Scientific Method

Have you ever wondered how many different types of animals live around your home, like in your backyard or a local park? Animals come in all shapes and sizes, each a small part of the amazing diversity of life. These differences can also help us to classify animals into different groups. One way people classify animals is by their phylum. Do you know which phylum you belong to? In this science project, you will investigate the diversity of the animal life around your home and try to figure out… Read more

Where Do Earthworms Hang Out When Food Is Around?

Science Fair Project Idea

Scientific Method

Earthworms are important for the soil and fun to study. In this science project, you will find where earthworms like to stay when food is around. Will they gather around the food, take food with them in their tunnels, or not be attracted to the food at all? You will fill four pots with dirt, add food and worms, and track their activity over one week to find out! Read more
