## Pulse Rates

### Objectives

• Students will know that the human body is made of systems with structures and functions that are related by studying the relationship between the pulmonary and cardiovascular systems.
• Student will use the scientific process by doing the pulse rate experiment.
• Students will analyze real-world data to recognize patterns and relationships by comparing data on graphs generated by a computer.
• Students will know that to compare and contrast observations and results is an essential skill in science by writing a conclusion connecting data and research.

### Procedure

• Generate a hypothesis.
• Research exercise and heart rates.
• During PE collect data and enter it into the worksheet.
• Generate a graph and write a results and conclusion statement based on the data collection and research.
