Strength of Glues

Science Fair Project Idea

Scientific Method

Try gluing wood together with different types of glue, e.g.: regular white glue, yellow wood glue, cyanoacrylate (super glue), and Liquid Nails. Glue a short piece (5-8 cm) to the center of a longer piece (15-30 cm). After the glue has dried for the recommended time, drill a small hole through the center of the joint, big enough to pass through a piece of coat-hanger wire. Cut a length of coat hanger wire, pass it through the hole, and twist the ends together to form a loop. Place the ends… Read more

Study Bottle Rocket Performance with Electronic Sensors

Science Fair Project Idea

Scientific Method

Rocket design and operation is a fascinating field and analyzing the flight path provides insight into the rocket's performance. In this project, you will take measurements of the flight path to evaluate how a change in the rocket design or launch procedure impacts the rocket's performance. Initially, while the bottle rocket expels water (or the rocket expels exhaust), the rocket gets a boost. This push is referred to as thrust and projects the rocket forward. Earth's gravity pulls the rocket… Read more

Tee Time: How Does Tee Height Affect Driving Distance?

Science Fair Project Idea

Scientific Method

If you're an avid golfer, this might be a fun project for you. When you're setting up to tee off out on the course, how much attention do you pay to putting the tee in the ground? The height of the tee can affect both where in the swing the club makes contact and where on the clubface the ball makes contact. Are you placing your tees at the right height to get the most distance from your swing? Read more

Test and Change the Air Quality of Your Environment

Science Fair Project Idea

Scientific Method

Do you ever wonder if the air inside is cleaner or dirtier than the air you breathe outside? In this science experiment, you will test it using an air quality monitor. Have you ever wondered how lighting a candle in your room impacts your air quality? Did you cook and not turn on the fan? How did it affect your breathing, and how did it impact the air quality? In this project, you can see how these environmental factors can improve or worsen the air you breathe every day. Read more

The Case of Mistaken Identity

Science Fair Project Idea

Scientific Method

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

It's probably difficult to imagine a time with no television, no movies, and no cartoons. But believe it or not, those times weren't so long ago! What did those kids do when they couldn't watch movies? One of the most popular toys during that time was a great-grandfather of the modern cartoon. This toy was called a "thaumatrope," and in this activity you're going to make (and test) your own thaumatrope to learn about how vision works! Read more

The Importance of Making Sure a Drug's Aim Is True

Science Fair Project Idea

Scientific Method

Scientists recently found that some small drugs can stop infection by the deadly Ebola virus in its tracks. Lab researchers found that these drugs bind to a protein that the Ebola virus uses to enter our cells, and this is how infection is prevented. However, this also means that the bound protein no longer functions in our cells. How might these drugs accidentally disrupt important biological processes in our bodies? What other proteins might these drugs bind to? In this science project,… Read more

The Paper Plate Hovercraft

Science Fair Project Idea

Scientific Method

You can make a very simple hovercraft with a stiff, disposable plate-a pie plate should work well-and a balloon. Glue a square of cardboard in the center of the bottom of the plate. Make a small hole through the center of both of these layers. Enlarge the hole slightly with a pencil. Push a balloon through the hole so that the opening is on the front side of the plate, and rest of the balloon sticks out from the back. Blow up the balloon, then set the plate down (balloon side up). What… Read more

Have you ever seen a game-winning “Hail Mary” pass in a football game, a baseball player throw in a ball from way out in the outfield, or a soccer goalie punt a ball all the way down the field? All of these actions involve a player trying to throw or kick a ball as far as possible. There is some sports science behind these throws and kicks – how do you know what angle to throw or kick the ball so it will go the farthest? Should you make a shallow throw (straight out, parallel to the ground), a… Read more
