Last Work Day

Learning Target: 

• I can demonstrate my understanding of force and motion

HOWLs Target:

• I keep working until the task is complete

Agenda

• Warm-up: REASONING VS EVIDENCE (2min)
• What is the difference between evidence and reasoning?
• Snowtubing Data Analysis worksheet
• Desmos graphing
• Desmos how-to video google classroom
• Compare and Contrast speeds at 20m, 120m, and graphed lines.
• example: At 20m the push start was faster by 2.5m/s than the sit start.
• Evidence sentences for 20m, 120m, and graphed lines
• example: The push start was faster at 20m which supports the claim that a push start is a faster tubing method.
• Free-Body Diagrams
• draw vectors for F(g), F(n), F(f), and if needed F(a) for both the control and your classes variable (double tube, running start, or spin start)
• Reasoning Section
• Compare the free body diagrams 
• What forces are the same in both diagrams?
• ex: The control and the push start are similar because both tubing methods have the same force of ...
• Do both diagrams have unbalanced forces?
• Contrast free body diagrams 
• How are the diagrams different? 
• ex. In contrast to the control, the push start has an applied force acting...
• Are the net forces the same or different?
• How does the difference or similarities between the free body diagrams cause what you state in the claim?

Homework:

• Snowtubing Project 3/23
