Below are sample questions representative of the exercises included on this worksheet and related 3.9 Friction as a Contact Force (Extension) skill assessments:

Problem 1Difficulty: Mastery

Sofia reviews a circle investigation note at the weather station.A student says, 'Friction is a contact force that can slow moving objects.'Data:Surface or setup | Observation----------------+------------smooth board | slid farfelt board | slowed quicklyWhich evidence best supports the student's idea?

AThe plastic puck moved farther on felt board, so friction made it faster.

BThe object changed weight during the test.

CFriction acted without any surfaces touching.

DThe plastic puck slowed or stopped sooner on felt board, where there was more rubbing.

Solution & Explanation:Friction happens when touching surfaces rub. The evidence shows more rubbing on felt board, so the object slowed or stopped sooner.

Problem 2Difficulty: Mastery

During a Grade 3 science activity at the library makerspace, Mateo uses a red data card.A student says, 'Friction is a contact force that can slow moving objects.'Data:Surface or setup | Observation----------------+------------smooth ramp | 22 cmrough ramp | 9 cmWhich evidence best supports the student's idea?

AThe toy bus moved farther on rough ramp, so friction made it faster.

BThe object changed weight during the test.

CThe toy bus slowed or stopped sooner on rough ramp, where there was more rubbing.

DFriction acted without any surfaces touching.

Solution & Explanation:Friction happens when touching surfaces rub. The evidence shows more rubbing on rough ramp, so the object slowed or stopped sooner.

Problem 3Difficulty: Mastery

Nora's group at the schoolyard records observations on a river chart.A student says, 'Friction is a contact force that can slow moving objects.'Data:Surface or setup | Observation----------------+------------waxed paper | 8 inchespaper towel | 3 inchesWhich evidence best supports the student's idea?

AThe small box moved farther on paper towel, so friction made it faster.

BThe small box slowed or stopped sooner on paper towel, where there was more rubbing.

CThe object changed weight during the test.

DFriction acted without any surfaces touching.

Solution & Explanation:Friction happens when touching surfaces rub. The evidence shows more rubbing on paper towel, so the object slowed or stopped sooner.
