Learners will determine their respiratory rate and explore the factors that affect breathing rate by filling out and using the Respiratory Chart provided in the lesson.

In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.

In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this outdoor, sensory activity, learners role play as animals trying to identify their "family's" scent and locate their "territory." Learners mark their territories and sniff out other territories

In this activity, learners use microarray technology to determine which genes are turned on and off at various points in the differentiation of pluripotent stem cells on their way to becoming pancreat

In this activity, learners explore what is and is not active play and how it contributes to a healthy body and mind. Making active play a routine part of every day is a key concept of the experience.

In this activity, learners explore the work of paleontologists.

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

In this outdoor activity, learners work in pairs using their senses—especially touch—to learn more about individual trees.

In this design challenge activity, learners build a four-stringed instrument that can play a tune.

Learners will build a homemade pump using a balloon, a mason jar, and some straws.

In this activity, learners compare plant and animal life in different habitats including a sidewalk crack and lawn. Learners sort human-made materials and natural materials found in each habitat.

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 about the heart (on page 22 of the PDF), learners examine sheep or chicken hearts to learn about the heart's structure and the flow of blood through the heart.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

Learners develop an understanding of air pressure in two different activities.

In this activity, learners use household materials to investigate and explore their ability to smell an odor.
