What’s items make up a classroom pendulum
String binder clip penny pencil and tape
Why do we do repeated trials
To balance out human errors and check accuracy
How long is the standard pendulum what is the standard mass and where is the standard release position
38cm one penny and parallel to the table
What does it mean to control variables or have a controlled experiment
Change one variable at a time
What are the variables we experimented with
Length of string release position mass
What was the only variable that changed are results
Length of string
How to get good grade
Be able to read a graph with experiment results and make predictions about how many swings will occur with different lengths of strings
What is the relationship between the length of the string and the number of swings
The shorter the string that more swings the longer the string less swings
