This is a simple and effective way to either demonstrate a controlled experiment, or to assign your students a safe, meaningful lab. All you need is a few simple materials. I have also included a quiz at the end with an answer key.
This lab covers topics and terms such as scientific method, controlled experiment hypothesis, independent and dependent variables, constants, etc. This presentation works best if you can alter it as you go. You can also change it to suit your needs or your specific vocabulary.
