• Different shoes

• Different surfaces

• Different scales

• different force

Investigations

LO: SWBAT investigate how forces of different
strengths affect the speed of objects.

DOL: Given scenarios, SW correctly identify
investigations that explore the forces on objects in at
least 4 of 5 questions.

SCI 5.6D Design a simple experimental investigation that tests the effect of force on an object.

SCI 5.2A Describe, plan, and implement simple experimental investigations testing one variable.

Multiple Choice

Which question is this experimental investigation most likely trying to answer?

• How does the type of shoe affect the amount of force required to pull it?

• How much do the different types of shoes weigh?

• How does a spring scale work?

• How much force is required to pull the high heel shoe?

Multiple Select

What are the variable(s) in the investigation?

• Different Cars

• Different height ramps

• Different ramps

• Differrent surfaces

Multiple Select

Students are designing an experimental investigation where they determine how the height of a ramp affects the speed of a toy car by measuring how long it takes for the toy car to travel down different-sized wood ramps. What can be done to improve the experiment?

• The ramps should all be the same height.

• The ramps should be made of different materials.

• The same car should be used on both ramps.

• The experimental design is correct the way it is

Multiple Choice

What is the variable in the experiment?

• different fan speeds

• boats of different heights

• boats of different matierals

• Boats of different masses

• Different surfaces

Multiple Choice

Which question is the students most likely trying to answer with this experimental investigation?

• How far does Boat 1 move when the fan is turned on?

• How does the size of a paper boat affect the distance it travels when a constant force is applied?

• Can a fan blow a paper boat across the table?

• How does the mass of a paper boat affect the distance it travels when a constant force is applied?

Multiple Choice

Which of the following statements regarding a simple experimental investigation is correct?

• Everything remains constant in a simple experimental investigation

• One variable is tested in a simple experimental investigation.

• Two variables can be tested in a simple experimental investigation.

Discussing Data

Evidence

List the evidence that supports your claim.

Reasoning

Justify why this evidence supports your

claim.

At 5 N, the train model traveled 100
cm in 0.85 seconds. At 3 N, the train
model traveled 100 cm in 1.76
seconds. Our observations show
that when we use a stronger force,
the train model travels faster.

The distance traveled does not
change. If the train takes less time
to travel the same distance, then
the train must be moving at a
faster speed.
