The Particle Theory of Matter
Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...
Curated OER
Properties of Matter
Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Creating the Ideal Cargo Boat
Students build boats out of clay to test the buoyancy of the boat in water. Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.
Curated OER
Sink or Swim
Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.

The Law of Conservation of Matter
The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

Electrical Resistivity
Young scholars examine how materials oppose the flow of an electrical current. For this resistivity lesson students complete several experiments on the differences between resistance and resistivity.
