Rocks are made of minerals, and minerals often have crystal shapes. In this fun activity about geometry in nature, learners create their own crystal shapes out of paper.

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

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 activity, learners build helicopters and launchers using wooden dowels and scrap paper. Use this activity to explore rotational motion and kinetic and potential energy.

In this activity, learners use information gathered from a variety of sources to design and make their own insect.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

Learners build a wind turbine and test it to see how much energy is created.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.

In this activity, learners separate the components of Gatorade using a home-made affinity column.

In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

Learners will build a homemade pump using a balloon, a mason jar, and some straws.

In this activity (Lesson 1), learners work in groups to create tide simulations.

In this activity (page 12), learners explore how molecules self-assemble and how molecules must fit together, like a lock and key, in order to identify each other and initiate a new function as a comb

In this activity, learners use an origami template to design eight amino acids. Learners configure the amino acids to form a protein. Use this activity to introduce proteins and amino acids.

In this activity (page 87 of the PDF), learners move their bodies to better understand the three axes of rotation: pitch, roll and yaw.

Using simple, inexpensive items, learners build and test submarine models.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.
