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

Learners observe projectile motion by launching wooden balls off of a table top. They set up a rubber-band launcher so that each ball experiences a consistent amount of force.

In this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers.

In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

This lab activity has learners create a pendulum with a one-second period.

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

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 math lesson, learners identify, describe, and construct the five regular polyhedra.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

In this combination chemistry and physics activity, learners explore water absorption in dried beans or peas and learn how this affects their physical properties.

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.

Learners use a variety of beans to represent a variety of species, and scatter these beans over a large piece of paper representing the environment.

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

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 related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

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

In this math lesson, learners construct box-and-whisker plots to analyze and compare data sets. Learners investigate whether or not long-legged people run faster than short-legged people.

Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.
