Did you know that the world record for the greatest number of jumps in a minute is more than 340? That's more than five jumps a second! How close do you think you can get to that number? If you are going to try to break the record, it might be important to figure out how jump rope length affects your success. Try your hand at this skipping science fair project and jump-start your chances for a jump rope record. If you have a smartphone available, you can use its accelerometer and a sensor app…
Do you ever feel like you need to move your legs faster than your parents do just to keep up with them? This could be because of the difference in leg length between you and your parents. How many more steps do you need to take compared to your parents to walk down the block? Can you use a walking test to determine how tall a person is? This science project will help you find out! You can even use your phone and a sensor app to record the steps and determine the pace.
Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Will a hygrometer help you to predict bad hair days(!) or can you use it to help predict the weather?

Did you know that your heart beats at different rates depending on what you're doing? The more physically active you are, the faster your heart beats. You can measure the rate your heart is beating by taking your pulse. This science fair project will show you how to take your pulse and help you investigate which daily activities get your heart beating the fastest.
If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will…
You might like to play in the autumn leaves and winter snow, but have you noticed that many birds don't like to stick around for the cold weather? And instead of the birds you're used to seeing in the warm months, your new feathered friends might be Canada geese. Why is that? Various types of birds and other animals travel from one place to another either in search of food, warmer temperatures, or other things they need to survive. This type of traveling is called migration. Try starting your…
