Using C.E.R to explain Newton’s 1st Law of Motion
In this activity you will solve two problems as a group. Every person in the group has to be able to solve
the problem independently. You will have to make sure that you and everybody else understand every
part of the solution to the problem. One person will be randomly selected to present the problem to the
class. Your individual grade will be based on the performance of that person on the board.
Part I. Assigned Group Problem to Explain using Claims, Evidence, and
Reasoning Format: Explain to the class on Monday how your use Newton’s 1st Law of
motion to solve the following question. In addition, you should use C.E.R. (Claims,
Evidence, Reasoning) format to complete the answer for each part of the question.
1) An astronaut, floating freely near the shuttle, is switching fuel tanks in a satellite. The
astronaut pulls out the empty fuel tank, then gets distracted and can’t remember
which tank is the full one and which is the empty one. The two tanks look just the
same.
a. Can the astronaut simply weigh the tanks to find the full tank? Why or why
not?
C
E
I claim….
This is where you answer the question
My evidence….
This is where you quote relevant information
My
reasoning….
This is where you show that you understand the science! To
do this well, state the physics concept(s) (law, equation, etc.)
and connect the claim and the evidence using the concept
you stated.
R
For Extra Credit: Put together a group demonstration (similar to Inertial Smorgasbord Stations, but
something totally different) for next class. Bring materials and be ready to present how this is an
example of Newton’s 1st Law of Motion.
b. Can the astronaut simply shake one tank and then the other to find the full
tank? Why or why not?
C
E
R
I claim….

and connect the claim and the evidence using the concept

Part II. Finding Examples of 1st Law: Your group is now responsible to
come up with an example of how Newton’s 1st Law applies and can help
explain a situation. Use picture/sketches, descriptions to demonstrate
how Newton’s 1st law is important and applies to this situation. (If you
have access to the Internet and like to use videos, and add annotations
to explain, what is fine as well)
Here is an example:

Explanation:
Claim: The pipe flying through the truck’s window demonstrates a
Newton’s 1st Law of Motion.
Evidence: The picture caption explains that the steel pipe was on the flatbed behind the
truck, and it shot through the front when the driver hit the brake suddenly.
Reasoning: This is an example of Newton’s 1st Law of Motion because the pipe was
moving with the truck. The steel pipe has a lot of inertia because it has a lot of mass
(made of steel). Since the pipe and the truck were both moving, object in motion will
stay in motion. The inertial of the steel pipe caused it to continue its motion because
there wasn’t enough friction to apply an unbalanced force when the truck suddenly
braked. This is why the steel pipe went through to the front of the truck window.
For Extra Credit: Put together a group demonstration (similar to Inertial Smorgasbord Stations, but
something totally different) for next class. Bring materials and be ready to present how this is an
example of Newton’s 1st Law of Motion.

2) I was grocery shopping for the month. At the beginning, when my cart was almost
empty, it was really easy to push (i). But by the end of my trip, when the shopping
cart was full of stuff, it became very difficult for me to move the cart (ii). I couldn’t fit
anything else so I decided to go to pay at the register. I had to make a ninetydegree turn to get in line, but the cart was so full that I couldn’t complete the turn. (iii)
