In this geology activity (page 3 of the PDF), learners simulate an earthquake with little more than an elastic band and drinking straws.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

Based on color photographic images, learners compare geological features on Earth and Mars to understand similarities and differences between the two planets, and consider the forces that created land

In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.

In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

In this activity, young learners will model land and water on the Earth's surface to make a unique piece of "Earth Art." Activity includes materials list, step-by-step instructions, STEM connections a

Learners build a model of the planets in the solar system. In their model, the planets are spaced in their relative distance from the Sun.

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.

This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

In this activity, teams of learners study magnetic fields at four separate stations: examining magnetic fields generated by everyday items, mapping out a magnetic field using a compass, creating model

In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

In this online interactive challenge, learners choose items to represent the Earth or solar system, then determine other items to represent the Moon, or Milky Way based on their relative size.

In this activity, young learners will make their own flower seed nursery in an egg carton.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

In this activity, learners explore the relative sizes and distances of objects in the solar system.
