Science Fair Project Idea
Plants have evolved many clever mechanisms to ensure that their seeds will wait for appropriate conditions before sprouting. Some may only germinate after a fire, others only after going through a cold spell. This project explores one important variable among many that determine the ideal conditions for seed germination.

Science Fair Project Idea
Do people treat someone differently based on his or her appearance? Specifically, how are their behaviors affected by the clothes a person wears? For instance, if somebody wears a formal suit, do you think others behave differently when interacting with that person compared to if he or she were wearing casual clothes, like blue jeans? In this science project, you will get to try and find out! Read more

This project shows how mathematical probability sometimes contradicts our intuition. Despite the fact that there are 365 days in a year, if you survey a random group of just 23 people there is a 50:50 chance that two of them will have the same birthday. Don't believe it? Try this project and see for yourself. Read more

Science Fair Project Idea
Mysteries and detective stories have been popular since the time of Sherlock Holmes. The solutions to these fictional cases often involve untangling seemingly contradictory evidence from eyewitnesses. This project studies one procedure used in the real-world process of eyewitness identification of criminal suspects: the lineup. How accurate are eyewitness identifications using various lineup methods? Read more

Science Fair Project Idea
Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether the kid standing next to you is your sister or your cousin? The biologist might be able to make some good guesses this way, but by using samples of your family's DNA, s/he could construct your whole family tree. In this project, you'll use Web-based computer… Read more

Science Fair Project Idea
There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please! Read more
