Science Fair Project Idea
If you have a multi-speed bike, you know that you can make it easier or harder to pedal just by shifting gears. Ever wonder how that works? You can investigate this a number of ways. A basic approach is to use a selection of spools of thread (with different diameters), a board with two nails, and a rubber band. Place a spool over each nail, and put the rubber band over them. Mark the 12:00 position on each spool so that you can count revolutions. Turn one spool through a full circle and… 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

You've probably observed from your own personal experiences that some actions are contagious. Yawning is a great example. When one person in a room yawns, several other people usually do, too. Coughing, clearing your throat, these are other actions that often seem contagious. But what about smiling? Have you ever walked down the street and had a random stranger smile at you? Did it make you happy? Did you smile back? In this science fair project, you'll investigate whether smiling is… Read more

All animals need to respond to changes in their immediate environment. The sensory structures of animals are each made to respond to distinct types of sensory stimuli: touch, taste, sound, light and smell. How are these stimuli received? Different animals have different strategies for receiving stimuli and develop specialized structures for doing so. Antennae, ears, noses, tongues, eyes, eye spots, hairs and bristles are all examples of sensory structures used by different animals to sense… Read more

If you've ever been on a long hike, you probably already know how hungry all that walking can make you. But if you're going a long distance, the last thing you want is a heavy pack of snacks on your back. So what can you bring along for a healthy, hunger-satisfying, lightweight snack? How about dried foods, like banana chips or beef jerky? Many foods have high water content. The drying process removes much of the water from the food, leaving behind a lighter, but equally nutritious snack. Just… Read more

Science Fair Project Idea
In our , we provided a template with four materials: two active materials that expand and contract in the physics sandbox mode, and two passive materials — one hard and one soft. The project mentioned material properties, but it did not go into much detail — you just used the default settings from the template. Changing the material properties can drastically change how your robots behave. Engineers must take material properties into account when designing robots and other machines.… Read more
