Our science curriculum map for the next two weeks focuses on gravity: "Students will investigate how objects are pulled toward the ground unless something holds them up (gravity)." I am required to teach 45 minutes of science a day, and I'm having a tough time finding enough material, that's appropriate for kindergarten, for two weeks. Our science curriculum has nothing on gravity (which is not uncommon, the curriculum rarely lines up with the kindergarten state standards :huh. Does anyone have any ideas for lessons or experiments involving gravity, or know of any free online resources for teaching about gravity? Thanks!
