IB Physics Skills: Validity Part 1

The video tutorial covers the concept of validity in IB physics experiments, focusing on independent, dependent, and controlled variables. It uses examples like an archery competition and a slingshot experiment to illustrate how these variables affect the validity of an experiment. The tutorial emphasizes the importance of controlling variables to draw meaningful conclusions and provides guidance on selecting appropriate variables for experiments.

What conclusions can be drawn if multiple independent variables are changed in an experiment?

What is the significance of measuring the correct dependent variable in an experiment?

In the archery competition example, what role does the type of bow play in the validity of the experiment?

How can the results of an experiment be affected by environmental conditions?
