Why did Vehicle 2 fall off the cliff in Claire’s test of the collision scene, but Vehicle 2 did not fall off the cliff in the film Iceworld Revenge?
Claim 1.
The vehicles in Iceworld Revenge had different masses; in Claire’s test, the vehicles had the same mass.
Question 1
1.
Which evidence cards can be used to support that claim 1?
need 3 because 1 card supports both
Evidence Card A
In the crash scene in Iceworld Revenge, Vehicle 1 slows somewhat before it collides with Vehicle 2. In her own test, Claire did not observe Vehicle 1 slowing down before the crash.
Evidence Card B
In Iceworld Revenge, Vehicle 2 moves slowly toward the cliff after the collision, stopping just before it goes over the edge. In Claire’s test, Vehicle 2 went over the cliff at full speed.
Evidence Card C
The surface (“road”) for the vehicles in Iceworld Revenge is clear and shiny. Claire’s film professor says the following materials might have been used. The friction of each substance is different. ice= low friction, plexiglass = medium friction, rubber= high friction
Evidence Card D
In Iceworld Revenge, Vehicle 1 appears to move in the opposite direction after the crash, but it is offscreen so you can’t see how far or how fast it is moving. In Claire’s test, Vehicle 1 came to a stop after the collision.
Evidence Card E
Claire’s film professor says these materials are commonly used for making miniature model vehicles. When painted, vehicles made from these materials all end up looking about the same. foam=low mass; plastic = medium mass; steel = high mass
Question 2
2.
Which of the following statements would support Claim 1?
Pick 2 from this list
The masses of the vehicles in
Iceworld Revenge
were different from each other, while in Claire’s test, the vehicles were the same mass.
A surface with more friction exerts a stronger force opposite the direction of motion, which would slow down that object even more
Friction is a force in the opposite direction of motion, which is what slows an object down.
Objects can only change their speed if they experience a force
This evidence shows that the objects experienced different changes in velocity from the collision.
Question 3
3.
Which of the following statements would support Claim 1?
Pick 3 from this list
It is possible to make the miniature cars look the same even if they are made out of materials with very different masses
Vehicle 2 stopped moving before it could fall off the cliff supports this piece.
A surface with more friction exerts a stronger force opposite the direction of motion, which would slow down that object even more
In a collision, both objects experience the same strength force, but in opposite directions.
Objects with less mass have a greater change in velocity from the same strength force
Claim 2
The friction of the surface that was used in Iceworld Revenge was different from the friction of the surface in Claire’s test.
Question 4
4.
Which evidence cards can be used to support that claim 2?
need 3 because 1 card supports both
Evidence Card A
In the crash scene in Iceworld Revenge, Vehicle 1 slows somewhat before it collides with Vehicle 2. In her own test, Claire did not observe Vehicle 1 slowing down before the crash.
Evidence Card B
In Iceworld Revenge, Vehicle 2 moves slowly toward the cliff after the collision, stopping just before it goes over the edge. In Claire’s test, Vehicle 2 went over the cliff at full speed.

Question 5
5.
Which of the following statements would support Claim 2?
Pick 3
The friction of the surface was different in
Iceworld Revenge
than in Claire’s test. Vehicle 1 slowed down before it collided with Vehicle 2
Objects with less mass have a greater change in velocity from the same strength force
Objects can only change their speed if they experience a force
The masses of the vehicles in
Iceworld Revenge
were different from each other, while in Claire’s test, the vehicles were the same mass.
Friction is a force in the opposite direction of motion, which is what slows an object down.
Question 6
6.
Which of the following statements would support Claim 2?
Pick 3
Objects with less mass have a greater change in velocity from the same strength force
This evidence shows that the objects experienced different changes in velocity from the collision.
A surface with more friction exerts a stronger force opposite the direction of motion, which would slow down that object even more
Plexiglass looks like glass in a video but it's friction is higher than glass, allowing objects to slow down even more
In a collision, both objects experience the same strength force, but in opposite directions.
The surface that looked like ice in
Iceworld Revenge
could have been something other than ice and that had higher friction than ice, such as plexiglass
Question 7
7.
Which Claim do you support?
Claim 1
The vehicles in Iceworld Revenge had different masses; in Claire’s test, the vehicles had the same mass.
Claim 2
The friction of the surface that was used in Iceworld Revenge was different from the friction of the surface in Claire’s test.
Combination of Both
Question 8
8.
WHY did you pick Claim 1, or Claim 2 or both?
Include 2 pieces of evidence
(it's ok to check your answers for questions 1-6 before picking your evidence)
