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.
This activity is meant to be used with the PowerPoint Lesson found here:
From the PowerPoint, students will also 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.
I have also included a grading rubric to make grading this lab simple and as quick as possible. Each section is worth a certain number of points, with more important sections worth more points.
The supplies used in this lab are the same ones as in the previous nad final labs in this series; just more wooden blocks will be needed.
