In this activity, learners will plot the distribution of various oozes using information from sediment maps.

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

In this activity (page 87 of the PDF), learners move their bodies to better understand the three axes of rotation: pitch, roll and yaw.

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

Learners investigate how drag affects the falling rate of objects.

In this activity, learners simulate whale echolocation. Learners experience echolocation by wearing blindfolds, while another learner makes snapping noises in front of, behind, or to the side of them.

This is an activity about discovering the colors and beauty of nature. Learners will spend time outdoors, matching paint chip samples, colored paper, or colors of clothing to those found in nature.

Learners work as a group to create a map of their community. They use pasta to represent people, and glue the pasta on their maps to show areas of large population.

In this activity, learners work in groups of four to explore light. Learners create new colors from the primary colors of light from flashlights covered in theatrical gels or cellophane.

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 observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.

This lesson introduces learners to the world of nematodes (roundworms).

In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

In this activity, learners explore how boats are engineered to achieve speed.

In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.

In this activity, learners explore how engineers design tire treads to increase safety and reliability.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

In this outdoor activity, learners play a game of Tag to discover how neurons attach themselves to each other to form a chain.

In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing
