In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners will build the highest tower they can out of recycled materials.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

In this activity, learners build bridges using paper and explore how much weight each bridge design can support.

In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity learners will build a neighborhood out of blocks and cardboard.

In this activity, learners will build ramps and test how the laws of physics apply do different objects. Learners will explore physics and cause and effect through this activity.

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

In this activity, learners are invited to imagine the park of their dreams!

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

This guide features three related ramp explorations in which learners investigate the following science concepts: when placed on a ramp, some objects roll, others slide, and others stay put; the shape

In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

Learners explore soybeans, soak them in water to remove their coat, and then split them open to look inside. They also make a musical shaker out of paper cups, a cardboard tube, and soybeans.

In this activity, learners build magnetic towers to explore the forces and properties of magnets.
