Science Fair Project Idea
Think of a way to launch the puck with a reproducible force, and examine the effect of launching the puck in different orientations on the distance it travels. For more information on the physics, see Haché, 2002. Read more

Does the force of drag have an effect on the distance the puck will travel? Think of a way to launch the puck with a reproducible force, and examine the effect of launching the puck in different orientations on the distance it travels. For more information on the physics, see Haché, 2002. Read more

Science Fair Project Idea
You'll need: a puck, a hockey stick, a tape measure, at least one helper with a stopwatch and an empty rink. Have your friend start the watch just as you make contact with the puck, and stop it when the puck hits the boards. Measure the distance and divide by the time to get the speed of the puck. With two helpers and two stop watches, you can time the puck at center ice and at the far end. Are the speeds the same? How about if you don't follow through, but stop your stick as soon as it… Read more

Science Fair Project Idea
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

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

Here's a fun project idea to learn about compression forces. For this experiment you'll need some empty toilet paper tubes, masking tape, sand (or table salt), pebbles (or marbles), a funnel, a cardboard box, and a sturdy chair to help you balance while testing the column. Seal one end of the tube with masking tape. Use the funnel to fill the tube with sand (or salt). Seal the other end with tape. Place the tube on end inside the paper box. Place the chair with its back to the box and hold… Read more

Science Fair Project Idea
How much difference does the spiraling motion of a well-thrown football make on the distance of the throw (compared to wobbling, or end-over-end motion of the ball)? Think of a way to reproducibly produce the desired ball motion and launch it with a constant force to find out. (For more information on the physics, see Gay, 2004.) Read more

thumbnail While watching an ice hockey game, have you ever wondered what differentiates a good player from a great player? For sure, the great player is athletically superior to the good player. But maybe it is a combination of athleticism and equipment. Maybe a great player knows which hockey stick is best for him or her. Hockey players can choose to play with hockey sticks with different flexibilities or "flex." In this science fair project, investigate how stick flex affects shot accuracy and speed.… Read more

Science Fair Project Idea
Research the famous collapse of the Tacoma Narrows suspension bridge. What lessons were learned about the potentially damaging effects of wind on bridges? What structures stabilize a bridge against wind forces? Build models and use a wind tunnel to test your hypothesis. Read more

Time Required Very Long (1+ months)
Science Fair Project Idea
Think about mountain ranges, canyons, sand dunes, or any other interesting geological feature you may live near enough to visit. The surface of the Earth is always changing due to a balance of forces both above and below the surface. Below-surface forces cause the Earth's crust to be faulted, folded, tilted, and lifted. Above-surface forces are primarily due to the natural processes of weathering and erosion. Can you show the effects of these forces using scale models, demonstrations,… Read more
