Investigate the 'Death' of an Orange: How is Rate of Heat Loss Based on the Surrounding Temperature?

Science Fair Project Idea

Scientific Method

Imagine that you are a detective investigating a murder. You have a body that was found in a swimming pool, and someone reported hearing an argument near the pool at 10:00 PM the night before. Your first question might be "Was this person killed around 10:00 PM last night, or at some other time?" One way to answer this question is to measure the internal temperature of the body. The longer ago the killing occurred, the colder the body. But can you assign a specific time of death to a specific… Read more

Have you ever watched an old movie, and when a character asks what time it is the other characters all look at the sky, instead of checking their watches, or their cell phones? There’s no giant digital clock in the sky, those characters are using the position of the Sun in the sky to tell time, as people have done for generations. The oldest known instruments for telling time, the sundial, allow us to track the position of the sun more accurately. Up until the early 19th century, sundials… Read more

Have you ever played with a Slinky, used a pinball machine, written with a click pen, or ridden in a car? If so, then you have used a spring. Springs are in machines all around us and have many useful purposes. In this activity you will learn how a spring can be used to make a scale to weigh objects. Read more

Motion Mania: Applying Physics to Hula-Hooping

Science Fair Project Idea

Scientific Method

Practice makes you better at most things, and knowledge makes practice so much easier! Can you swirl a circular toy called a hula hoop around your waist or arm? Is it hard? What knowledge can you apply to find ways that make hula-hooping easier? Physics! Yes, physics will help you determine what makes one hula hoop a winner and another a flop. In this project, you will create your own hula hoops, spin them, and draw conclusions. The road will then be open to your becoming a hula hoop expert. If… Read more

Did you know that not all animals use their ears to ‘hear’ sounds? Snakes, for example, perceive sound waves through their jaw bones! And many insects perceive sound waves through their antennae. While these methods of detecting sound might be different, they all respond to the same thing that our ears do, which is sound waves in the environment. In this activity you will generate some impressive sound waves from very simple materials, and observe how these sound waves are… Read more

Pop Goes the Metal: How Temperature Affects Snap Time of a Jumping Disc

Science Fair Project Idea

Scientific Method

Jumping discs can be a fun toy to play with, and with their sudden POP!, they can even be a good way to startle people who have never heard them before. Jumping discs use a neat trick to jump. They are made of two different types of metal, and these metals expand when they heat up (or shrink when they cool down), but not by exactly the same amount. In this science project you will explore how temperature affects the reactions of your jumping discs— and how to get the timing right if you… Read more

Have you ever wondered how fast a heavy object falls compared to a lighter one? Imagine if you dropped both of them at the same time. Which would hit the ground first? Would it be the heavier one because it weighs more? Or would they hit the ground at the same time? In the late 1500s C.E. in Italy, Galileo was actually asking some of these same questions and did some tests to answer them. In this activity, you’ll do some of your own tests to determine… Read more
