Too Hot to Handle

In a classic activity, emerging electricians test various objects for electrical conductivity in a circuit. Each group constructs a simple circuit by following a diagram. Predictions are made and objects are inserted into the circuit,...

Youngsters compare the heat-holding abilities of three different cans by insulating two with different materials and measuring the temperature change of hot water over a 20-minute period. 

Pupils test various materials to learn if the materials are conductors or insulators. They observe a small electric charge go through, or not go through, a material to light up a small bulb.

Here is a very important demonstration on why it's so important to wear helmets when doing any kind of high speed activity. A third grader's science fair project tested four different types of helmet: football, ski, skateboard, and...

Extend your class's observation skills with a video about additional properties of matter. The video covers the ways an item can be altered, including its hardness, malleability, conductivity, and magnetism as information you can use to...

Find the right science fair project. Steve Spangler shows how to use a demonstration and turn it into an experiment. Additionally, he talks about the importance of coming up with a hypothesis.

Why did the orchestra director use a copper baton? She heard it makes a great conductor. Scholars select six items to test in a circuit to determine if each is a conductor or an insulator. Clear instructions for using electricity allow...

Learn about the center of mass and projectiles by examining the movement of Olympic figure skaters! Physics and skating fans will be delighted as they watch super athletes perform unbelievable feats. Arrows and text appear to highlight...

Learn about germs without getting sick! An interactive resource prompts learners to identify the dirtiest surfaces on a city street. Class members then participate in a demonstration about washing dirty hands and how using soap can kill...

What is an insulator? What materials make the best insulator? Watch as Joanne and Steve conduct a simple experiment to see if a plastic cup insulates better than a styrofoam cup. Make a prediction: which do you think will be the better...
