Inquiry Pendulum Lab with CER
During this lab students will change three variables on the pendulum- length of string, angle of release, and mass of the bob. They will test and understand the relationship between the variable being tested and the period.
Materials needed for each group: Ring stand (or some way to hang the pendulum), string, hanging masses (or a cup full of pennies, marbles, etc), stopwatch, and a protractor.
Included are 2 versions of this lab:
This inquiry version in class takes 2 class periods. Day 1 is spent understanding the variables and figuring out relationships, and day 2 is spent collecting data. At the end of day 2 they will either write a conclusion based on their findings or fill out a CER chart.
In this distance-learning version, students will make their own pendulum and collect data. If you are worried about students not having needed materials, a youtube video is included that students can watch and record data from.
Both versions are completely editable!
This is great for a high school physics class or can also be used in any science class to reinforce the scientific method, variables, and understanding why we only change one variable at a time.
