Hi everyone, I am new to this site so please forgive me if I'm in the wrong spot. I just started my first week of teaching. I was wondering if anyone had any advice on teaching independent variables and dependent variables. I wanted to start out with an easy lab (posing a question-9th grade level) for students to understand themselves what independent and dependent variable is, control, and constants. Does anyone have any ideas how to start out this topic? Thank you!
