In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

In this activity about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this activity, learners compete to be the first to win twenty counting pieces. First, learners draw patterns on only one side of four craft sticks.

In this math activity, learners experiment with the concept of symmetry.

In this math lesson, learners follow step-by-step directions for making tangram pieces out of folded and torn paper. First, learners read "Grandfather Tang's Story" by Ann Tompert.

In this activity, learners develop spatial reasoning skills as they blow bubbles and observe what happens when the bubbles connect.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the

In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.

In this activity, early learners combine pre-cut recognizable shapes and their own abstract ideas to make representational pictures (e.g. houses, trees, shoes).

This activity introduces learners to the structure and properties of carbon nanotubes.

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

In this math activity, learners sort patterns into similar "families" or groups that have the same pattern, but different symbols.

In this math activity, learners make toothpick designs by following simple patterns.
