I require that all of my students read the lab as homework the night before we actually do the lab experiment. Students must complete this worksheet as they read the lab. By answering a few simple questions, students will be well prepared to do the lab experiment. They will identify the purpose of the lab, they will identify safety precautions, and they will make predictions as to the outcome of the lab. The lab always runs much smoother and is much more meaningful to the students when they are well prepared before hand.
This handout can be used with any grade level old enough to complete lab work, and it can be used with any type of science class.
