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 science and language arts activity, learners study fish anatomy and make their very own 3D paper fish.

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

Learners take on the role of environmental engineers as they design water filters.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

Learners build simple catapults and use them to launch cotton balls.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

Learners construct and launch paper helicopters.

In this activity, learners make a model of a beehive using simple materials.

"Nature of Dye" allows participants to create their own dyes and art while exploring how chemicals interact and how these interactions can have real-world applications.

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this lesson, learners cut paper into very small pieces to explore the small size of quarks, the smallest thing we know of on Earth.

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.
