The purpose of this kinesthetic activity is for students to learn the relative motions of the Earth, Sun and Moon. Awareness of these different motions is needed to develop an understanding of the causes of the day/night cycle, the seasons and the cycle of lunar phases. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers ... Full description.

This lesson attempts to correct the common misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere. Proceeding from student preconceptions, small groups participate in an exploration of the cause of the seasons using a basketball, small globes and a lamp.

Comment on this resource
This lesson addresses the common student misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere. This lesson encourages students to voice this misconception at the beginning of the lesson and then attempts to correct it-first, by exploring the reason for it, and then by presenting an alternate explanation. Materials needed for the demonstration include a small ... Full description.

This activity, effective outdoors or indoors, demonstrates how insolation is affected by latitude by using a pair of thermometers, each taped to some cardboard, placed outside on a sunny day. A globe can also be used, outdoors or indoors. Students learn that seasonal variations in temperature are the result of the heating of the Sun as a function of its peak angle and length of the day. A template ... Full description.

This is an activity about seasons. Learners begin by brainstorming a list of activities and events that occur in each season. Next, learners perform an experiment by comparing the temperature on thermometers left under a lamp for different lengths of time to illustrate that Earth heats more when the Sun is in the sky longer.

In this kinesthetic activity, learners act out the rotation and revolution motions of Earth around the Sun over the course of one year. Learners also physically model the tilt of the Earth and will identify the summer and winter solstice and vernal and autumnal equinox locations in relation to Earth's orbit around the Sun.

This is an activity about the measurement of time. Learners model the rotation of Earth over one day by holding a flashlight for the Sun and a blow up globe, and record their observations. Then, they use those observations to create devices that will track time and test their devices outside. This final part of this activity requires access to a sunny outdoor location for an extended period of time ... Full description.
