We Will: investigate the difference between mass and weight as it relates to Newton’s Laws of Motion
I Will: finish Tow Mater and gather data for this activity, finishing it in class today as time allows.
Question 1
1.

If you could travel to these places instantly... check all the places your weight would change.

Question 2
2.

Weight can increase without changing the mass of an object?

Question 3
3.

An objects mass can change without changing the amount of matter in the substance

Question 4
4.

Which of the following apply to the law of conservaiton of matter

Question 5
5.

Weight is...

Question 6
6.

Mass is...

Take a moment to think about your observations of weight you have experienced in the world. The first step of the scientific method is to observe the world around you.
Question for thought: What is the relationship between mass and weight?
Question 7
7.

Hypothesis. Read over your lab procedures for today. Design a testable hypothesis to the question above using an if/then format.

Question 8
8.

When you hook a mass to a spring scale what happens to the spring

Question 9
9.

What does the length of the spring indicate about the mass hanging from it?

Question 10
10.

What is the SI unit for mass?

Question 11
11.

What is the unit for Force?

Question 12
12.

What is the symbol for Force

Procedure: (12 minutes)
Watch the following virtual experiment and record the data for each 8 trials in the google sheets


Data Analysis: Using your gathered data, graph the Force acting on the spring scale on the y-axis vs the mass on the x-axis.
Use the following video and collect the following data Link to google sheet to create your data table and graph.
