5th Grade Force STAAR Review

Students designed an investigation to determine how far a ball would travel when released at the top of two ramps of different heights. They set up the investigation shown below. What should the lab team do to improve their investigation?

• Use Ball A on both ramps.

• Use Ramp 2 for both balls.

• Use Ramp 1 for both balls.

• Place Ball B on Ramp 1 and Ball A on Ramp 2.

A spring scale is a tool that measures the strength of force needed to move an object. The force is measured in Newtons (N). A student sets up two spring scales pulling wooden boxes of different masses across a table. Which question is this investigation most likely designed to answer?

• How does mass affect the force needed to move an object?

• How does the surface affect the force needed to move an object?

• How do wooden blocks affect spring scales?

• How does the mass of one block affect the mass of another block?

Students pull a spring scale attached to a 100-gram block across four different surfaces. Why is the amount of force needed to move the block different in each trial?

• The mass of the block changes.

• The material of the block changes.

• The surface the block is pulled across changes.

• The mass of the spring scale changes.

A student investigated how mass affects force needed to move objects. A student pulled a spring scale attached to a book across a table and recorded the force needed to move the book. Then she placed another book on top of the first book. She pulled the two books across the table and recorded the force needed to move the book. Which of the following is a valid conclusion for this investigation?

• The less mass an object has, the more force required to move it.

• The mass of one book affects the mass of two books.

• The more mass an object has, the less force required to move it.

• The more mass an object has, the more force required to move it.

An engineer wants to test the ability of 3 materials to resist cracking. She drops a heavy metal ball from 1 meter above each test material. She can improve the investigation by—

• dropping a different size ball for each material.

• using materials that are the same thickness.

• testing only one material.

• using a feather instead of a metal ball.

The diagrams show two trials of an investigation in which the distance a ball

rolls when released on cardboard ramps is measured. This investigation can be used to determine—

• how a ball’s mass affects distance it rolls.

• how the material a ramp is made of affects the distance a ball rolls.

• how a ramp’s angle affects the distance a ball rolls.

• how a ball affects a ramp’s height.

Ball - ​ (b)  

Surface - ​ (c)  

Bounces - ​ (d)  

• constant
• independent
• dependent

A student is conducting an investigation using a spring scale to compare the force needed to move blocks with the same volume and different masses across the floor. Which statement is best supported by this investigation?

• Glass requires less force than wood to move.

• Wood moves without any force.

• The copper requires the most force to move.

• Wood requires the most force to move.
