Great resource and interactive activities about friction.

Interactive on atomic structure.

Good resources for K-8

In this lesson, students use a variety of resources to explore the concepts of potential, kinetic, and total energy within different types of systems. Students watch a video that explains the transfer of energy in a trebuchet's release, use an interactive activity to determine the types of energy involved in different parts of a roller coaster ride, do an in-class investigation that demonstrates the effect of mass and gravity on energy systems, explore the difference between gravitational and elastic potential energy, and finally, use the formulas for kinetic and potential energy to examine the path of a projectile.

Students can adjust the angle and velocity of a projectile shot out of a cannon and draw conclusions about the projectile's motion.

Interactive temperature scale comparison activity.
