On the first night, I saw 5 stars in the desert. On the second night, I saw 10… What do you think I saw on the third night? Combine arts and crafts, literacy, and math by making a counting book.

In this activity, learners construct three quick and simple mechanisms to start building a pop-up book. Learners fold, cut, and glue paper to make a bird beak, parallelogram, and V-fold.

In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

Put the math of measurement, numbers, and everyday life into improvisational skits.

In this activity, learners construct a home-made journal with simple, everyday materials.

In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

In this physics activity, learners will investigate the strength of egg shells.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.

In this math lesson, learners play two different games to help them understand coordinates. First, learners read the book, "The Fly on the Ceiling," by Julie Glass.

In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

This magic trick is based on how computers detect and correct data errors.

In this quick activity (page 1 of the PDF under SciGirls Activity: Tug O' War), learners will test how many pennies a flat paper index card bridging the gap between two stacks of books is able to supp

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

In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.
