Mastering Independent and Dependent Variables in Science Experiments

The video tutorial introduces the concepts of independent and dependent variables in scientific experiments. It explains how independent variables are manipulated to observe changes in dependent variables. The tutorial provides examples and practice questions to reinforce understanding. Viewers are encouraged to download a PDF for further practice and to believe in their ability to master the concepts.
