The classroom activities are explained throughout the unit; however, a set of activity sheets immediately follow this section. In these activity sheets, the students go through a microcosmic example of the whole unit: they complete pre- and post-surveys, fill out data tables, create a double-bar graph, analyze the data, and do so in a scientific method process.
How do our heart rates change from resting to jogging?

Your carotid artery is the artery that brings blood from your heart to your brain. It pulses each time your heart beats. To feel your pulse, put your index and middle fingers together, place the fingertips directly under your ear, and then slide them down until they’re right under your jawbone. If you press lightly, you’ll feel the pulse. Make that you don’t press too hard; you should push just enough to feel the pulse. If you don’t find it, try a different spot.
1. Count the number of heart beats in one minute while you are sitting at your desk
2. Write the number on line 1 of the
Resting Data Table
3. Find the results of four other students and write them in on lines 2-5
4. Tell a partner what you think will happen to your heart rate when you start jogging -- hypothesis
5. Begin jogging in place
6. When your teacher tells you, begin taking your pulse again
7. Write the number on line 1 of the
Jogging Data Table
8. Find the results of four other students and write them in on lines 2-5
