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

In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

In this activity, learners will train to increase bone strength and to improve heart and other muscle endurance by performing jump training with a rope, both while stationary and moving.

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this activity about living things and gravity (page 5 of PDF), learners design and build an exoskeleton or an endoskeleton for an animal of their own invention.

In this activity (page 32 of PDF), learners investigate the nutritional needs of healthy bones and muscles.

In this activity about human anatomy (page 20 of PDF), learners investigate the structure of muscles by comparing yarn and cooked meat.

In this activity, learners will train to improve lung, heart, and other muscle endurance as they walk a progressive, measured distance.

In this activity, learners train to increase muscular strength and improve upper and lower body coordination by performing the “bear crawl” and the "crab walk.” Learners perform the exercises over tim

In this activity, learners explore cooked chicken wings and identify the various parts including: bones (radius, ulna, humerus, shoulder joint, elbow joint), tendons, and cartilage.

In this activity, learners will train to develop upper and lower body strength in their muscles and bones by performing body-weight squats and push-ups.

In this activity about human anatomy (page 16 of PDF), learners construct a model arm and discover how muscles and bones work together to achieve efficient movement.

In this activity, learners explore the importance of active play.

In this activity about center of gravity (page 23 of PDF), learners investigate how the body adjusts to the force of gravity to remain balanced.

In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.

In this activity and game, learners will train to improve balance and spatial awareness by performing throwing and catching techniques on one foot.

In this activity about physical stress (page 28 of PDF), learners discover that muscles and bones need to work to stay strong.

In this activity about heart health (on page 27 of the PDF), learners measure their heart rates after a variety of physical activities and compare the results with their resting heart rates, and with
