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
Huddle & Cuddle: How Puppies Keep Warm
Science Fair Project Idea
Scientific Method
What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss. Read more
It's Crowded in Here! A Study of Plant Population Density
Science Fair Project Idea
Scientific Method
Like humans, plants can be negatively affected by overcrowding. Unlike humans, plants cannot get up and move to a new environment or explore how to utilize new resources. This experiment will explore the effects of crowding (population density) on the growth and health of plants. Read more
Ladybug Spots and Breeding
Science Fair Project Idea
Scientific Method
Ladybugs are common insects in North American gardens that prey upon aphids, making them all the rage in biological pest control. Ladybugs can be bred in captivity making them a good insect to study. Just chop off an aphid infested plant stem for food, make a water soaked cotton ball for water, and add to a small plastic container with a lid to make a breeding box. You can use ladybugs collected from the wild, or buy ladybugs from your local nursery. The most common species is the 12-spotted… Read more
Making Species Maps
Science Fair Project Idea
Scientific Method
How do conservation biologists know which places are important to protect? How do nature guides know which animals can be found in which places? In this experiment you can discover how maps can be used to show how different animals are distributed in a local environment. Read 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
Moss is Boss: Using Plants to Determine Direction
Science Fair Project Idea
Scientific Method
Have you ever gone camping, looked up at the stars, and found the Big Dipper? Two stars in the dipper part of this constellation point to Polaris, the north star, which people have used for thousands of years to help them find their way. In this plant biology science fair project, you'll investigate whether plants, like moss, can help you find your way, too. Read more
Plants Are On The Move! A Study of Gravitropism
Science Fair Project Idea
Scientific Method
As we humans zip from place to place, we often forget to stop and smell the roses. Compared to our fast-paced lifestyle, plants seem rooted to the spot. Don't be deceived by appearances however, plants are on the move! This experiment will investigate the stimulus/response relationship in plants and prove that plants can move up and down in response to gravity. Read more
