Connections to ILS Goal 12 Gravity relates to goal 12.D.3b Gravity relates to goal 12.D.3b Explain the factors that affect the gravitational forces on objects Light relates to goal 12.C.2a Light relates to goal 12.C.2a Describe types of energy including light Moon relates to goal 12.F.2a Moon relates to goal 12.F.2a Explain natural cycles in the solar system

There is no gravity in Space Misconception (identify and confront) Misconception (identify and confront) Astronauts seem to float when in space (gravity acts on objects without being in contact) Resolve misconception Discuss weightless experiences students have had Discuss and model Newton’s 1 st and 2 nd law of motion Reinforce Computer simulation of an object orbiting the earth so that students can see the force of gravity keeping the object in orbit.

Light brightens objects More light brightens objects to make them more visible (identify and confront) More light brightens objects to make them more visible (identify and confront) Resolve Resolve Computer simulation demonstrating light source from electrons jumping to new orbits. Reinforce Reinforce Focus on the interception of light as it effects seeing using a pinhole Lab activity and exploring convex and concave lenses as they affect images.

The Moon The moon revolves around the earth in one day (identify and confront) The moon revolves around the earth in one day (identify and confront) Moon appears to travel once around in a day because of the earth’s rotation Resolve Resolve A computer simulation demonstrating the earth’s rotation in conjunction with the moon’s rotation Reinforce Reinforce Provide physical models of the earth, moon and sun to demonstrate the phases of the moon as it rotates around the earth
