This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

In this great hands-on activity, learners use patterns to make a teepee from newspaper that they sit inside.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners will explore coding by arranging words and phrases to create an order of operations in this low tech version of computer programming.

In this activity, learners build a nanorover model using styrofoam meat trays and a balloon.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

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

In this activity, learners will build the highest tower they can out of recycled materials.

In this activity, learners compare water pressure at different depths. Learners discover that water pressure increases with depth.

In this activity, learners explore motion, energy, and electricity by constructing bottle cars that run on motors.

This activity (page 2 of the PDF under SciGirls Activity: Microgravity) is a full inquiry investigation into how ordinary things behave in microgravity, similar to what astronauts experience.

Visitors observe three beakers. One beaker contains an egg immersed in vinegar. Visitors observe carbon dioxide gas escaping from the shell as the calcium carbonate reacts with the vinegar.
