Local Heart Rates
- Grade Level: Upper Elementary - Middle School
- Subject Area: Science
Students will determine the type of data needed to test their inferences from lesson one. As homework, they will check and record heart rates of fellow students, teachers and family members. During their next class period, the students will enter all data into the database.
- Determine the type of data the students must gather to test the inferences from lesson one.
- Choose test subjects according to the data they need to gather.
- Check and record heart rates of fellow students, teachers and family members.
- Gather data.
- Enter the data into the database.
Materials and Resources
- Paper, pencil and a watch with a second hand.
In developing our lessons and activities, we made some assumptions about the hardware and software that would be available in the classroom for teachers who visit the LETSNet Website. We assume that teachers using our Internet-based lessons or activities have a computer (PC or Macintosh) with the necessary hardware components (mouse, keyboard, and monitor) as well as software (operating system, TCP/IP software, networking or dial-up software, e-mail and a World Wide Web client program, preferably Netscape, but perhaps Mosaic or Lynx). In the section below, we specify any "special" hardware or software requirements for a lesson or activity (in addition to those described above) and the level of Internet access required to do the activity.
- Special hardware requirements: none.
- Special software requirements: none.
- Internet access: none.
Optional- a prepared chart for recording data that includes check boxes for the categories your testing for (example: gender, lifestyle which could include activity level, diet, smoker vs non-smoker etc.) and a space to fill in the name and heart rate of the person tested.
- Discuss the types of data the students must gather to test the questions in lesson one. (Does gender, lifestyle, activity level or culture effect heart rate?)
- Decide which factors you will test for and determine the type of data you will need to gather.
- Depending on your inferences, direct each student to find and record the heart rates of at least five other people. Encourage them to choose test subjects according to the data they need to gather (example: activity level, age, gender and ethnic group, etc.). Students must also record the activity level, age, gender and ethnic group of each entry.
- Enter all data into a database for future analysis.
