This is a hands-on lab activity about seawater density, specifically the relationship between density of fluid, weight of an object, and buoyancy. Learners will develop hypotheses and observe a demonstration of density to understand its role in... (View More)

This activity has two purposes: challenge the learner to develop a procedure for investigating a research question and to learn more about factors affecting the dynamics of air in motion. It demonstrates that warm air and cold air differ in weight... (View More)

This experimental activity is designed to develop an understanding that air has mass. Students conduct an investigation and observe the change in the position of a bar balancing a balloon inflated with air on one end and a uninflated balloon on the... (View More)

This learning activity engages students in measurement of pH in water and soil samples, plants and other natural materials. By mixing different substances, they observe how pH changes, and become familiar with the pH of common household products.... (View More)

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)

In this introductory classroom activity, students exercise their scientific skills of observation and deduction as they use their senses and simple laboratory assays, such as pH indicator paper, to identify mystery pollutants in water samples.... (View More)

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)

In this activity, students investigate the interacting parts of the Earth system by observing changes in evaporation rate in four small aquariums with different initial conditions. The demonstration requires 4 small aquariums, soil, plants, water,... (View More)

This is an activity about lava flows on the Moon. Learners will understand some of the geological processes and the structures that form as lava flows across planetary landscapes by using mud as an analog for lava. This activity is in Unit 2 of the... (View More)

This is an activity about lunar and terrestrial stratigraphy. Learners will study the patterns of lava flow by creating eruptions using soda-vinegar solutions and modeling with home-made playdough (stove-top and no-cook recipes are included). This... (View More)
