I have made a quick whole group lab sheet that goes with the TEK 4.5A classifying matter. In this TEK you are supposed to test an objects ability to sink or float. I made a simple table that will allow students to name the objects the teacher has picked out, their prediction if they think the item will sink or float and then what did the item actually do. I hope this finds you to be very helpful and a quick and easy way to add in a lab to your class.
