Fourth graders investigate the principles and uses of gears, and examine how gears can be used to alter the direction of motion or the speed of an object. They observe two cars with different sized wheels roll down an inclined plane,...

Students identify how the tilt and position of the Earth causes the seasons. After a discussion of the seasons and when they begin. Using themselves as the objects in the universe, they role play how the rotational movement of the...

Students explore the migratory movements of animals as they monitor their own movements throughout the school day. Climatic and feeding conditions are examined as cues for the movement.
