Scientific Method
Everyone has experienced the warmth provided by a shaft of sunlight through a window. In this physics science fair project, you will determine how the color of an object affects the amount of radiant energy that is absorbed. You will then use the Stefan-Boltzmann equation to determine the amount of energy that is absorbed and re-emitted by the different colors. Read more

Have you ever driven across a bridge or seen a building that is under construction and noticed the large metal support beams? What about all the wooden beams in a house that is under construction? Did you notice how sometimes the beams formed different geometric shapes, like triangles or squares? In this project you will be a structural engineer and make your own “support” shapes out of popsicle sticks. What shape will be the strongest? Read more

Engineering Design Process
Can you build a volleyball machine? It will need one part to launch a ping pong ball over a net and another to return the ball. How many back-and-forth volleys can you get before the ball touches the ground? Looking for inspiration? You can see how other students have tackled this and other annual Science Buddies Engineering Challenges. Teachers, lesson plan versions of this challenge are available. Read more

Have you ever seen a rainbow after a rainfall, or drawn a rainbow for fun? They can be fun to make using colorful markers or other craft supplies. But did you know you can actually make a simple rainbow using milk, liquid detergent (i.e., soap), and food coloring? How the rainbow is created by this mixture might surprise you! In this science activity, you will make your own milk rainbow and explore how detergent and surface tension are involved in its creation. Read more

What's an easy way to move liquid from one place to another? A siphon! With just a little effort to get it started, you can then sit back and watch liquid flow from one container to another, as it seemingly defies gravity by going uphill. Try this activity to make your own simple siphon using straws. Read more

Have you ever played with your own shadow? It is fascinating how it follows your every move. But why do you not see your shadow every day? Why is your shadow very long sometimes, and other times very short? In this activity, you will make your own shadow puppet and explore how you can change the shape or size of its shadow. If you like, you can even create your own shadow play! Read more

Scientific Method
Did you know that you can use magnets to build a train that floats above its tracks? In this project, you will also use magnets to make the train stop, preventing it from crashing into the end of the track. Will adding more magnets help the train stop sooner? Read more
