Science Fair Project Idea
thumbnail There is evidence to be gathered at every crime scene. The hard part is making sense of it all. That's where crime scene investigators and forensic scientists come in. In this science fair project, you will investigate blood spatter using fake blood. Your job, as an impartial scientist, is to deliver facts so that justice can be served. Are you up to the challenge?

thumbnail Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… Read more

thumbnail Why do so many people use cell phone cases? Do cell phones really need the extra protection, or is it just because cases look fancy? In this engineering science project, you will test the durability of calculators instead of cell phones, find out if cases increase the durability of the device, and build some of your own cases that do!

When you open up your presents on your birthday, you probably don't spend a lot of time admiring the wrapping—you'd much rather see what's inside. It can be the same way with the packaging that products come in, but packaging is important for protecting the things we buy as they make their way from the factory to our homes. How much shock force is produced when a box gets dropped accidentally? What kinds of materials work best to protect products from damage? This project can show you… Read more

thumbnail Watch out! It's Eddy Vortex, Superhero! He swirls, he tumbles, he churns up air and water! OK, maybe eddies and vortices aren't exactly superheroes, but they are powerful regions of air and water flow that you have to watch out for in some surprising places. Try out this science fair project to discover why, as well as where and how to find them. Read more

Science Fair Project Idea
thumbnail Have you ever looked at two girls and thought they looked so similar that they must be sisters? What about a father and his son — have you ever seen a boy who looked just like how his father did when he was younger? We can often tell that two people are related because they appear to have several similar physical traits. This is because children receive half of their DNA — their genetic blueprints — from each parent. What about fingerprints — are they an inherited trait?… Read more

Time Required Short (2-5 days)
Prerequisites Basic understanding of genetic inheritance

Consent forms must be signed for each person participating in this experiment. You should inform people that although fingerprints can be used as forms of identification, you will assign their fingerprints a code and not use their name so that the fingerprints remain anonymous. For children under the age of 18, parents must grant consent. In addition, the fair's Scientific Review Committee (SRC) must approve the experimental design (including consent forms).

Science Fair Project Idea
Standing on a balcony near the top of the Tower of Pisa in Italy, a young scientist dropped two balls into the crowd below. The scientist, young Galileo, was not trying to knock his fellow professors on the head, but was trying to prove his theory that all objects fall to earth at the same rate, regardless of their mass. Was Galileo's theory correct? In this science project, you will get to test it out for yourself! Look out below! Read more

thumbnail Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment.In this geology science project, you… Read more
