2 class periods of 60 minutes each
Students will choose an organ or organ system and design an experiment to test it.
These will vary depending on what you have. Ideally:
- blood pressure cuff
- lung volume bags
- breath control analyzer (measures how long you can blow steadily into a tube)
- grip meters
- oral thermometer and alcohol cleaning solution
- meter stick
- clock with second hand or stopwatches
- Measurements of Body Systems sheet (attached)
- student sheet (attached)
Background for Teachers
30-50 minutes for student to choose activity and set up their experiment. 30 minutes to collect data, 30 minutest to report results
- Gather the materials available. Your health teacher may have things you never dreamed of in a closet. Barbara Gentry at JSD can also lend you items. Many grocery store pharmacies have blood pressure machines and occasionally a bone scan is performed there also.
- Show your students the materials and describe their use. You might call a health professional to come and talk to the class about the measurements and what they mean. Make an overhead of the list printed below to guide the discussion.
- Place students in groups of 3 or 4 and hand out the student sheets.
- Read over the sheets with students and make sure they understand their assignment.
- Have students pick their system or instrument they will use. Two groups may do the same measurement if you have enough equipment. Make sure they test a different variable.
- Check student-designed experiments. Check for groups that attempt to test two variables, a common mistake. They should repeat the experiment enough times to trust their results.
