Learning Objective:

To describe friction and identify factors that determine the friction force between two objects

Learning Activities:

1. Do Now- Open your science notebook to the experiment on p.81 and get out “Shipping & Sliding” lab handout and your data table and Try the rotating staircase optical illusion.
2. Science Friday- Dawn of the Cyborg Bacteria
3. Experiment- Shipping and Sliding (Friction)
• As a full class, design a graph
• In your lab group, complete gathering data in your data table. Calculate the average and graph the average data on your graph.
