This activity (on pages 16-23) lets learners measure each other's vital signs—the signs that help doctors understand what's going on in a patient body.

Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.

During this lesson, learners will determine their blood pressure and learn about systolic and diastolic pressures.

This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.

In this activity, learners take their own pulse and explore how heart rate is affected by various activities.

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

This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

Learners will construct a model of a heart valve using a film canister, a piece of masking tape, and a piece of paper.

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

In this game (on pages 14-21), learners explore how each human being inherits genetic traits such as eye color.

In this activity (on pages 22-33), learners do the kind of work genetic scientists do, sorting and comparing (images of) genetic material strands called chromosomes.

This activity explores what it means for a computer to be intelligent and introduces the topic of what a computer program is and how everything computers do simply involves following instructions writ

By building a model of a lung and diaphragm, learners discover the function of various parts of the body's respiratory system.

In this activity, learners will investigate the sounds of the heart.

In this craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

In this activity, learners explore the great pump in their chests--the human heart!
