| Number of Sessions to teach the topic |
1 - 2 sessions
|
| Educational standards to be addressed |
- MS-LS1-3
Construct an explanation supported by evidence for how the body is composed of interacting systems consisting of cells, tissues, and organs working together to maintain homeostasis.
- SL.8.5
Integrate multimedia and visual displays into presentations to clarify information, strengthen claims and evidence, and add interest.
- RST.6-8.9
Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from reading a text or prepared information on the same topic.

| COSMOS concepts to be used for the lab |
Detecting, recording and converting natural impulses into electronic data and displaying such data in a usable format.
|
| K12 Educational Goals (How the educational goals are achieved through teaching using the experiment, how the topic is connected to the COSMOS concepts used) |
The pulse rate before and after physical activity is different and students will observe, in real time, the recording of their actual pulse rates on the COSMOS Educational Toolkit and compare how they feel before and after physical activity.
|
| Short Description and Walk-through of the experiment |
Students will be introduced to the lesson with a short slide show on the heart as a pump and how the heartbeat creates the pulse rate. Students will work in groups of 2 take each other’s pulse rate as recorded on the COSMOS Educational Toolkit. One student will take their pulse rate first and the other will record the readings in a table. Afterwards the second student will have his turn to do the activity. When both students have completed the activity they will answer questions at the end of the handout relating to the activity they just did.
|
| Testbed mapping of the experiment |
This experiment can also be done on the WITEST, ORBIT, and COSMOS testbeds to give real time observations.
|
| Virtual Reality mapping of the experiment |
This experiment would be very interesting if done using Virtual Reality mapping as students could visualize their own pulse rate changes before and after physical activity in a virtual environment.
