In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

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 team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this team design challenge (page 2-10 of PDF), learners design and build a model of a Lunar Transport Rover that will carry equipment and people on the surface of the Moon.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this team design challenge (page 11-18 of PDF), learners design and build a Landing Pod for a model Lunar Rover (previously built in activity on page 1-10 of PDF).

In this activity (page 1 of the PDF under SciGirls Activity: Double Dutch), learners will stand twelve feet apart swinging a rope at the slowest tempo possible while someone uses a stopwatch to record

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

In this math lesson (on Page 13), learners predict and simulate the likelihood of an event occurring.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this environmental health activity, learners investigate their own vital lung capacities.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.
