In this activity, learners use simple tools to build a bookshelf with a built-in bookend.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.

In this story time program, young learners listen to the Dr.

This activity introduces the idea of "divide and conquer" using a fictitious but serious problem--a pair of dirty socks has accidentally been wrapped in one of the presents that Santa is about to deli

In this engineering activity, young learners investigate multi-level buildings.

This magic trick is based on how computers detect and correct data errors.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

In this activity, learners design, build, test and redesign a display tower that will meet a specific set of criteria and constraints.

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 engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

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