This lab demonstrates Ohm's law as students set up simple circuits each composed of a battery, lamp and resistor. Students calculate the current flowing through the circuits they create by solving linear equations. After solving for the current, I, for each set resistance value, students plot the three points on a Cartesian plane and note the line that is formed. They also see the direct correlation between the amount of current flowing through the lamp and its brightness.

This lesson introduces students to the concept of air pressure. Students will explore how air pressure creates force on an object. They will study the relationship between air pressure and the velocity of moving air.

By using the discrepant event of dropping a burning candle in a jar, students will predict, experiment, and discuss why the candle goes out as soon as it is caught.

Have you ever poured sand out of a buckey, or poured cereal out of a box, and noticed it is a lot like pouring water? It is because sand and cereal are granular materials. This means they are made up of solid particles, but they can flow like liquids! Candies, like Skittles, M&M's, Nerds and many others, are also granular materials. In this science activity, you will investigate physics and how the size and shape of granular materials affect how they flow.
