The objective of the lesson is for students to learn about the relationship between distance and intensity of radiation, and also to consider the many sources of radiation in our environment and their effect on our health. Also, students will practice clearly communicating scientific results in the form of a lab report.
Students will perform some background research, and then remotely operate the equipment at the radiation lab at the University of Queensland in Australia to test their hypothesis. All of this is available for free for all high school students. Its a great resource!
Step 1: Background Research
Step 2: Designing and Completing the Experiment
The site uses flash player for several portions of the investigation, so make sure its updates on your classroom computers.
At this screen they have the choice of several different versions of the experiment depending on what they are studying including physics, ap physics, biology, chemistry, or mathematics. Each version of the experiment changes the context that is provided for the students. I included some screen shots of the different variations that are available for high school students.
The activity starts with a pre-lab, leads the students through the design of their investigation, has the students send their remote instructions to the lab, shows the students the execution of their instructions on a webcam, leads them through data analysis, and guides them in the preparation of their lab report. The authors of the activities do a great job with questioning the students during the process and relating the content to the scenario set up in the lesson.
Step 3: Simulation and Web Cam Screens
All of the data is stored within a student account, so all students have to do to view their data after it has been submitted to the equipment and recorded is log back into their account with ilab.
