In this activity, learners explore how boats are engineered to achieve speed.

In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this activity, learners will discover how our universe is continuously expanding.

In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

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

In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.

In this activity, learners will explore engineering concepts to construct a blanket fort using materials sourced from home.

No glue is needed for learners of any age to become marshmallow architects or engineers.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

In this activity, learners will create their very own constellation.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

In this activity, learners build a scale model of the solar system using a roll of toilet paper.
