Quiz; brightness followup;
Grade the quiz in-class and turn in papers to the teacher.
Next activity is the inverse square law for light. If you can write out proper procedures and accurately predict the outcome of the lab, you don't have to do the lab.
Given:
A light source (small)
A light sensor (digital)
A meterstick
Design an experiment to determine the relationship between distance and and brightness. Include:
Independent
Dependent
Interfering variables
Planned procedure
Discuss each variable and tell how it is controlled
Predict the kind of data you will get if you did the lab for real
Expected Result should include a prediction about the graph.
The abstract should contain the variables, possibly the hypothesis, and the results.
