Polar Opposites
Source Institutions
In this activity, learners make a 3-D model of magnetic fields by inserting a small, strong magnet into a sphere.
Exploring Fabrication: Self-Assembly
Source Institutions
In this activity, learners participate in several full-body interactive games to model the process of self-assembly in nature and nanotechnology.
Make a Lake
Source Institutions
Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?
Saguaro Nest Cavities
Source Institutions
This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.
Ice on Mars
Source Institutions
In this activity, learners use sand and ice cubes to create a model of permafrost and the effects of the ice melting through the surface.
Lupine and Butterflies
Source Institutions
In this two-part activity about the connection between the lupine plant and butterflies, learners first read "Miss Rumphius," a storybook about lupine by Barbara Cooney.
Water Bugs
Source Institutions
Some bugs can walk on the surface of a lake, stream, river, pond or ocean.
A Crayon Rock Cycle- Sedimentary
Source Institutions
This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.
Build a Tree
Source Institutions
This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Teen Moon: Moon Ooze
Source Institutions
In this activity, learners model how the Moon's volcanic period reshaped its earlier features.
Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.
Tidepool in the Classroom
Source Institutions
In this activity (page 4 of the pdf), learners build a model of a tide pool, using chicken wire, paper mache, and other craft materials.
Rain Forest in Your Room
Source Institutions
This activity (on pages 19-24) introduces learners to the rain forest's layers—emergent, canopy, understory, and forest floor—and has learners make paper lianas (vines that live attached to trees) and
Coral Spawning Globe
Source Institutions
This activity models the mass coral spawning event that takes place at Flower Garden Banks National Marine Sanctuary every August.
Rocking Changes
Source Institutions
In this earth science activity, learners conduct a series of short experiments to explore how rocks change.
Design and Build a Wind Vane
Source Institutions
In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.
What is a "Model"?
Source Institutions
In this activity, learners simulate the behavior of the atmosphere.
Crumple a Watershed
Source Institutions
Learners gain an intuitive knowledge of the physical aspects of watersheds by creating their own watershed models.
Web Weavers
Source Institutions
In this outdoor science/art activity, learners investigate spider webs by using string to create their own spider webs.
