This is the second in a 3 part lab series dealing with Friction, but it can be used as a standalone activity. Students will be using spring scales to measure the force of friction created when dragging wooden blocks across the tabletop.
From the PowerPoint, students will be guided through the steps of the scientific method (another great review) as they move from questions, to creating a hypothesis, to copying a procedure, collecting data, drawing a graph, and finally writing a well thought out conclusion.
Doing this activity makes it easy to incorporate a writing activity into your science lesson.
The supplies used in this lab are the same ones as in the previous lab in this series; just more wooden blocks will be needed.
