Make a paper airplane and experiment with adding winglets to it to test its performance. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms,...

Experiment with different sizes of parachutes to find out if size matters when slowing the descent of the parachute. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

This is a really fun project even if you don't like going on roller coasters yourself. You'll build a roller coaster track for marbles using foam pipe insulation and masking tape, and see how much of an initial drop is required to get...

Skyscrapers are impressive structures. What does it take to design a building so tall? Engineers use strong materials and innovative design to push the limits of gravity. In this experiment you will use LEGO components, rubber balls, and...

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...

You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of...

Lots of people enjoy roller coasters, but not many understand why they feel the strange excitement they do when riding them. In this science fair project, you will build and use an accelerometer to figure out and measure gravity-induced...

In this science fair project, investigate the effect of speed on the distance and height of the skateboard trick the "ollie". The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and...

Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back. What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing.
