68 reviews
Different types of birds lay their eggs in different places. Some build tiny nests in bushes, some build enormous nests in tall trees. Some lay their eggs directly on the ground or on rocky ledges. Those that build nests use many different types of materials. In this project you will try to build your own bird nest using only natural materials that you can find outside. Can you do better than a bird? Read more
Ocean Bioluminescence: Investigate When and How Dinoflagellates Glow
Science Fair Project Idea
Scientific Method
Imagine the ocean water turning bright red or seeing ocean waves glowing a beautiful blue color. Sounds impossible—but it is not! Red tides and glowing waves are caused by microscopic organisms living in the ocean called dinoflagellates. Some dinoflagellates have the ability to produce light through a process called bioluminescence. When and how do these organisms glow? In this science project, you will investigate how changing the dinoflagellate's exposure to light and dark affects its… Read more
Caffeine and Heart Rate: A Pharmacological Study Using Daphnia magna
Science Fair Project Idea
Scientific Method
In this project, water fleas (Daphnia magna), a semi-transparent freshwater crustacean, are used to study the effects of caffeine on heart rate. Don't worry about having to learn how to take a crustacean's pulse: you can actually see the heart beating under a microscope. Many variations of this experiment are possible. Read more

If you could choose to be an animal, would you rather be a predator or prey? For prey animals, survival in the wild means a daily struggle to escape potential predators. Predators, on the other hand, have to work very hard to make a catch. Some prey animals have evolved clever strategies to protect or defend themselves against predators. One common strategy is camouflage. Camouflage allows animals to blend into their surroundings so predators can't see them. Will this strategy increase an… Read more

Earthworms are important for the soil and a lot of fun to study. Few people know there are over 2,000 types of earthworms. Some like to burrow deep in the soil, while others stay near the surface. Do you know what they eat, or what their eating and burrowing habits are? Fill a pot with moist dirt, add a few worms, and observe your worms to find out. Read more
Classify Animals with Machine Learning
Science Fair Project Idea
Engineering Design Process
How do you tell the difference between a bird and a fish? Birds tend to have feathers and can fly, while fish have no legs and can breathe underwater. In this project, you will explore how to create a decision tree using machine learning that can classify different animals based on multiple characteristics. This project is designed for beginners and requires little to no coding experience. Ready to give it a shot? 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
Maze-solving by an Amoeboid Organism
Science Fair Project Idea
Scientific Method
Can a simple organism that lives off of dead trees and that grows as a mass of protoplasm actually have intelligence? The goal of this science fair project is to test the ability of the slime mold Physarum polycephalum to solve the problem of finding the shortest path through a maze. Read more
Understanding Wolf Behavior from GPS Tracking Data
Science Fair Project Idea
Scientific Method
If you were leaving home for a long walk, how far would you go? One mile, 5 miles, 10 miles? How about 550 miles?! That's a long way, but some wolves have been known to travel that far when they are leaving their packs in search of a mate so they can form their own pack. But is that how far wolves normally travel? Try this wild wolf tracking science fair project to find out! Read more

Do you love to hear the pulsing chirp of crickets as you fall asleep? It is an unmistakable sound. Some people find the sound pleasing and peaceful, but other people find the sound loud and annoying, especially if a cricket happens to get inside a home to escape the cold. However you feel about crickets, their chirps hold a surprising message — they can be used to predict the temperature! In this science activity, you will investigate how the chirps of these tiny creatures can be used… Read more
