This investigation looks at the effects of increasing the exercise on your heart rate. It is geared for 4th and 5th grade students. Please check out the k-1st and 2nd/3rd grade heart rate journals on my store.
Students will follow the scientific method to answer the question. Students will brainstorm their prior knowledge to write a hypothesis. They will learn how to take their pulse and calculate the beats per minute. Students will integrate their math skills to calculate the mean of each trial and create a bar graph. Students will summarize their data, come up with possible errors, and answer questions about the investigation. By the end of the investigation students should be able to:
* Identify the independent variable, dependent variable, constants, and control in the experiment
* Correctly write a hypothesis and summarize the results
* Understand the role of the heart in exercise
* Correctly calculate the mean and create bar graph
