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

Growth and Age

Science Fair Project Idea

Scientific Method

One thing that all living things have in common is that they grow through cell division. How is this growth regulated? Sometimes growth occurs when it is not supposed to, leading to cancer. Scientists are trying to discover how growth is regulated, hoping to find potential cures for cancer. One idea is that cells keep track of growth using special regions of the chromosome called "telomeres" that count how many divisions a cell has made. If this is true, then growth, cell division and age are… 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

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

How Sweet It Is! Explore the Roles of Color and Sugar Content in Hummingbirds' Food Preferences.

Science Fair Project Idea

Scientific Method

Do you like to watch hummingbirds? Have you ever wondered why there is specialty hummingbird food? What is it about the food that makes it so appealing? In this zoology science fair project, you will observe these remarkable creatures and learn how color and sugar concentration influence a hummingbird's selection of a food source. 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

Respiration and Gills: What Factors Affect Respiration in an Aquatic Environment?

Science Fair Project Idea

Scientific Method

During metabolism, organisms experience physical and chemical changes. All animals need some way to exchange chemical waste generated during metabolism for fresh nutrients. One way that these metabolic chemicals are exchanged is during respiration, the process by which used carbon dioxide gas is exchanged with fresh oxygen and circulated throughout the body. How do organisms living underwater respirate? They use gills, which filter oxygen from the water and pass the oxygen into the… Read more

Springtime Science: What’s Home Sweet Home to a Bug?

STEM Activity

Have you ever wondered how an animal chooses what type of environment to live in? With the arrival of spring, in many areas flowers will be blooming and animals will be emerging from their winter hiding places and searching for a place to live until next winter. One group of critters that can usually be found just about anywhere on land includes sowbugs and pillbugs. As they come out to enjoy the warmer weather, what type of environment do you think they’ll seek? In this science activity,… 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

Have you ever wondered how whales and other marine mammals survive and keep warm in the cold oceans? Warm-blooded mammals can live in these chilly conditions because their bodies have some cool warmth-saving adaptations, thanks to generations of natural selection. In other words, to pass on characteristics (via their genes), the predecessors of modern marine mammals had to overcome different challenges to reproduce, and their descendants received the genes that allowed for their survival.… Read more
