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.
