This activity is designed to introduce students to planetary geologic features and processes. First, students will use NASA satellite images to identify geologic surface features on the "Blue Marble" (Earth), and will explore the connection between... (View More) those features and the geologic processes that created them. Using that information, students will then compare and discuss similar features on images from other planets. Included are the following materials: teacher's guide (with reference and resource information), student's guide (with activity sheets), and multiple cards of planetary images. Note that the range of targeted grade levels is quite broad; however, explicit adaptations for younger students are highlighted throughout the teacher's guide. (View Less)

Students will time the flow of water through soils with different properties and measure the amount of water held in these soils. They will also experiment with the filtering ability of soils by testing the pH of the water before and after it passes... (View More) through the soil and observing changes to the clarity of the water and to the characteristics of the soil. Students build an experimental apparatus using a two-liter beverage bottle, observe the movement of water through the simulated soil column, and replicate the same experiment using different soil types. This is a learning activity associated with the GLOBE soil investigations and is supported by the Soils chapter of the GLOBE Teacher's Guide. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)

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) the potential evapotranspiration, average monthly temperatures and precipitation for their model. This is a learning activity associated with the GLOBE hydrology investigations and is supported by the Hydrology chapter of the GLOBE Teacher's Guide. (View Less)

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) for the lessons include clipboards, thermometers, graph paper, and flashlights. This investigation is from "Everyday Classroom Tools," a series of lessons focusing on the changing seasons and other aspects of our everyday existence. Each lesson contains information on cognitive development, an introductory inquiry activity, and an inquiry investigation. An introduction to inquiry in education and related educational resources (especially connections to folklore) are provided for educators. Differentiation is provided for K-2, grades 2-4 and grades 4-6. (View Less)
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 investigation is from...

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) making activity supports this investigation.
