In this craft activity, learners create a string of cut-out moons and stars.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

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.

This is an online simulation of how sound changes due to environment. How does place--like a cave, a pier, or a forest--affect certain sounds?

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

In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

In this activity, learners explore the web of connections among living and non-living things.

In this activity, young learners (2 years and up) explore turtle basic adaptations and biology. Turtle external anatomy is explored by "building" a turtle with a nature collage.

In this activity (located in the middle of the page), learners start a garden by planting their socks!

In this activity, learners investigate how some butterfly wings get their color.

In this activity, learn about the cultural stories behind constellations. Then recreate your favorite constellations using marshmallows and toothpicks.

This is an activity about turbidity, or the amount of sediment suspended in water.

In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.

In this activity, learners will engineer a roof using simple materials to protect a construction paper person from a rainstorm.

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

In this activity, learners will experiment to find how long it takes to compost paper. They will create their own compost container and test different variables.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

In this game, learners try to find nano-related objects on a game board. Learners investigate the different ways nano is in the world around us.

In this activity, learners will design a seed and test how it travels. Learners will use the Engineering Design Process to create a seed which can move from place to place.
