In this science fair project, use a globe and a heat lamp to investigate how the angle of the Sun affects global warming. This project includes the objective, background questions, a list of all the materials you'll need, and the...

Students graph data reflecting time of day and length of shadow, and then draw conclusions about Earth's seasons and position in relation to the Sun.

[Free Registration/Login Required] View how the axis of rotation causes Earth to have seasons on this site. Also test your knowledge on how the position of Earth and seasons relate with a short quiz.

In this activity, students' will explore how the tilt of the earth's axis results in different amounts of solar radiation at different times of the year, causing seasons. They will simulate the earth's warming using a light bulb that...
