In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

In this technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.

In this activity, learners investigate the properties of graphene and graphite.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this technology activity, learners build simple circuits, design soft circuits using conductive thread, and then sew switch-activated circuits.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.

In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
