Students create a physical model illustrating soil water balance using drinking glasses to represent the soil column, and explain how the model can be used to interpret data and form predictions. Using data from the GLOBE Data Server, they calculate... (View More)

This is an online lesson which introduces the concept of astronomical filters and their connections to imaging different objects in space. Learners will explore perceptions of images as seen using different colors of light, construct a filter wheel,... (View More)

The effects of volcanoes on both the environment and people are the focus of this investigation. Students are introduced to the term "buffer" and are tasked with creating a possible buffer zone around Mount St. Helens. Students begin by assigning 32... (View More)

This is an activity about planetary sizes and distances. Learners will construct a scale model of the Earth, Earth’s Moon and Mars in relation to each other using balloons. They will use this model to predict distances and reflect on how... (View More)

This is an activity about size, distance, and perspective. Learners will observe two objects of the same size placed at different distances, and they will observe two objects of different size placed at varying distances. This concept is then... (View More)

This is an activity about gravity. Learners will design their own experiments to explore the fundamental force of gravity and then extend their thinking to how gravity acts to keep objects like moons and ring particles in orbit. They use the... (View More)

In this inquiry investigation, students study the motion and positions of the Earth and how they affect the path of sunlight we get in different places. They discover that the Earth must be curved to account for the different lengths of shadows at... (View More)

In this inquiry investigation, students discover that the Earth is tilted on its spin axis, and that the tilt is responsible for the seasons. Supplies required include a globe, flashlights, golf tees and blue-tak. This is the ninth of 10 inquiry... (View More)

In this inquiry investigation, students conclude that the motion of the Earth is linked to the changes we observe such as the length of the day. Students learn about the reason behind the Earth's time zones. An optional water clock and sand clock... (View More)

In this inquiry investigation, students discover how a given amount of light changes in intensity when the area it shines on changes, and that change in light and heat occurs when the Earth is tilted towards or away from the Sun. Supplies required... (View More)
