This is an activity about seasons. Learners compare the seasons though identifying seasonal activities and drawing scenes in each season. Then, they compare the temperature on thermometers left under a lamp for different lengths of time to explore... (View More)

This is a book about seasons. Learners will read or listen to a story about two twins, Matt and Matilda, who are tasked with creating a model of the Earth-Sun system for a science fair project. Through some wild seasonal changes they experience... (View More)

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... (View More)

This is an activity about the concept of direct versus indirect sunlight. Learners construct and use a sun angle analyzer to investigate the effect of angle on area illuminated. The fraction of light on each square of the analyzer is then calculated... (View More)

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... (View More)

In this laboratory activity, learners explore the difference between heat and temperature, and explore the rate of heat transfer from one substance to another as it depends on the density of the substances being investigated. The activity can be... (View More)

This is an activity about understanding how the Earth’s axial tilt changes the angle at which sunlight hits the Earth, contributing to the variations in temperature throughout the seasons. Learners will create a sun angle analyzer in order to see... (View More)
