What our Circulatory and Cardiovascular System STEM lesson plan includes

Lesson Objectives and Overview: Circulatory and Cardiovascular System STEM teaches students about the structure and functions of this body system. Students will be able to explain how and why to keep the circulatory system healthy. They will also discover how it works with other body systems to function properly. This lesson is for students in 4th grade, 5th grade, and 6th grade.

Classroom Procedure

Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the yellow box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand. For this lesson, you will need red and green markers, water, large containers, and measuring cups. You might also choose to get a timer for the activity.

Options for Lesson

In the “Options for Lesson” section of the classroom procedure page, you will see some suggestions for additional activities or ideas to add to the lesson if you want to. One idea is to have students calculate the mean, median, mode, and range of the heart rates of the students in the class. (You may benefit from pairing this lesson with a math lesson related to central tendency and graphing.) Students could change the amount of water or size of the measuring cup to reflect different stages in life—child versus adult—during the practice. Consider talking about different animals and their hearts and how they differ from those of humans. Another option is to have a veterinarian come to the class to talk about the different circulatory systems of animals and compare them to humans.

Teacher Notes

The teacher notes page provides an extra paragraph of information to help guide the lesson. You can use the blank lines to write down any other ideas or thoughts you have about the topic as you prepare.


The Circulatory and Cardiovascular System STEM lesson plan includes three worksheets: an activity worksheet, a practice worksheet, and a homework assignment. Each one will help students solidify their grasp of the material they learned throughout the lesson. You can refer to the classroom procedure guidelines to know when to hand out each worksheet.

Worksheet Answer Keys

If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.
