In the Exercise project Norbert and Zot are on their Galactic Fitness 9000 treadmills. Their NASA doctor and trainer has asked them to exercise 60 minutes a day and maintain an average heart rate of 100 beats per minute. She has divided their 60 minutes into six 10 minute periods with a constant heart rate during each period. Your first job is to pick heart rate targets for each segment to make their average come out to 100 beats per minute. Then you become the trainer and pick a good exercise plan for them and estimate their average heart rate for your plan. Finally, to you need to take data on your own heart rate and plot the data and analyze it. Plot your data using the Squeak HeartPlot project. Then you will see how heart rate changes as you exercise.

We would like to see the heart rate data you take and the plots you make. You can save the HeartRate project with your data and plot using the publish button on the navigator flap. Everyone is different so comparing data from many different people is very instructive. Go to the NASA CONNECT web site to submit your results and we will post them.

After you are familiar with the Squeak Exercise project, try these challenges. Explore, create, and have fun learning.
