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

When discussing material properties, most of us usually think of solid materials and material properties such as hardness, flexibility, or strength. However, liquids are characterized by distinct properties, too. Some of these properties overlap with those of solids, like density or transparency, but others are more specific to liquids. Viscosity—the resistance of a fluid to flow—and surface tension, are two examples of properties that are specifically used to characterize liquids.… Read more

How do trees suck water all the way up to their leaves? How do paper towels soak up a spill? Are these things related? Try this project to learn about capillary action, and repeat a classic demonstration from over 100 years ago! Read more

Mixing Mystery: Why Does Tumbling Sometimes Separate Mixtures?

Science Fair Project Idea

Scientific Method

What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container Read more

Have you ever spent time spinning a hula hoop around your waist or arm? Could you easily do it, or was it difficult? Have you ever wondered how hula hoops work, or, in other words, what makes them be able to spin around a person's waist or arm? It comes down to the physics that is involved. Physics can help you determine what makes one hula hoop a winner and another a flop. In this activity you will get to create your own hula hoops and investigate how their masses affect how they spin. … 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

Pulley'ing Your Own Weight

Lesson Plan Grade: 3rd-5th

Using common materials (spools, string, soap), students learn how a pulley can be used to easily change the direction of a force, making the moving of large objects easier. They see the difference between fixed and movable pulleys, and the mechanical advantage gained with multiple/combined pulleys. They also learn the many ways engineers use pulleys for everyday purposes.Engineering Connection Thousands of years ago as well as today, engineers used pulleys to make everyday… Read more
