In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

This activity focuses on interactions within Earth systems and the effects of human activities. In this activity learners build a biomass pyramid.

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

In this activity, learners manipulate film to create homemade movies. Scratch Film, also known as Direct Animation, is the process of drawing and scratching designs directly onto film.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

Learners design and create musical instruments from common objects; their challenge is to create an instrument that can make three different tones.

In this math lesson, learners apply the concepts of ratio and proportion to the capture-recapture statistical procedure.

This assortment of mathematical games can be played while traveling.

This lesson focuses on graphene and its electrical properties and applications.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

Water treatment on a large scale enables the supply of clean drinking water to communities.
