How can we use tools to investigate physical properties?

Explore Activity: Investigate Physical Properties

During this experiment called, Investigate Physical Properties, students answered the question, How can you use tools to investigate physical properties?  The students made and compared observations using tools like a microscope, and a hand lens. They observed materials like: burlap, silk, felt, paper towel and sandpaper. Predictions were made on whether or not observations would change if the shape of the material changed when they cut it.
