In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

In this weather activity which requires adult supervision, learners will get a chance to make a cloud right here on Earth!

In this activity (page 13 of the PDF), learners discover how weathering and erosion change the Earth’s surface.

In this activity, learners will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this chemistry activity (page 3 of the PDF), learners will learn about crystals by growing their very own.

In this geology activity (page 6 of the PDF), learners explore how carbonic acid can slowly dissolve limestone and form caves.

In this activity, learners create a "mini sky" in a glass of water in a dark room.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

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 construct a coastal landmass from sand and add features such as tidal creeks and barrier islands.

In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

In this activity, learners model, on a human-sized board game, how changes in water temperature may affect fish distributions and, ultimately, fisheries.

In this activity, learners examine photo images of Earth taken from space, and attempt to identify and explain some of our planet's geological features.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.

In this activity (located at the bottom of the page), learners investigate soil and explore the creatures that live in it.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.
