• ### Activity and Exercise

Lesson

Students jump over a rope in different ways and measure their performance over time. They also predict their levels of “perceived exertion” during physical exercise.

• ### Body Strength

Lesson

Students learn that muscles need exercise to stay strong, repetition of exercises builds strength and endurance, and that different activities improve cardiovascular health, strength, flexibility and balance.

• ### Heart Rate and Exercise

Lesson

Students measure their prior to conducting a variety of physical activities. After conducting the activities, they measure and compare their post-exercise heart rates to their resting heart rates.

• ### Gravity and Muscles

Lesson

Students learn about the body’s center of gravity, and how the body adjusts to the force of gravity to remain balanced.

• ### Walk the Talk

Lesson

Students learn that physical and mental activities can be improved with practice by repeatedly walking while reciting a poem.

• ### Human Body Ratios

Lesson

Students practice estimating and measuring in metric units, and investigate the concepts of ratio and proportion as they relate to features of the human body.

• ### Body Mass Index (BMI)

Lesson

Students investigate how Body Mass Index (BMI) values are calculated, and how the information can be used in research.

• ### Water in Your Body

Lesson

Students learn how much water our bodies need each day, how it is lost, and that the water we lose must be replaced.

• ### Food: What Is a Calorie?

Lesson
