In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

In this activity, learners investigate the formation of craters. Learners will examine how the size, angle and speed of a meteorite's impact affects the properties of craters.

In this activity (on pages 36-39), learners make a model of a watershed out of paper, then run water down the mountain to simulate how rainfall and pollution affect watersheds.

In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

Learners create a model of a wetland to observe how it absorbs and filters water from the environment.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this quick activity, learners explore how blubber protects animals from the cold by making a "blubber mitt." Using cooking shortening, two zip-top sandwich bags, and duct tape, learners simulate bl

In this activity (on pages 29-35), learners examine water pollution and filtration.

In this hands-on activity, learners simulate the crashing and smashing of a meteor impact using household cooking supplies.

In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.

Historically, sea floor mapping (bathymetry) was done by soundings.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners use simple materials to simulate the effect of X-rays in a safe way. Learners place a piece of window screen over a box and a cardboard pattern on top of the screen.

This activity (on pages 23-27) lets learners simulate the work of scientists who take core samples of Earth's rocky layers to determine geological history.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.
