Keep the following questions in mind as you work.

• What happened as you moved the paper clip from 10 spaces away to five spaces away?
• What did you observe as you moved the paper clip closer to the magnet?
• What did you observe as you moved the paper clip farther away from the magnet?
• Was one magnet stronger than another?

Click Grade 3: Forces at Work to access the lesson for the Grade 3—Force and Motion strand.

Gather the materials necessary to do the Elaborate, Part 1 activity. Read through the Teacher Note, Content Builder, and Advance Preparation in the lesson. Follow the directions in Teacher Instruction to do the activity.

Keep the following questions in mind as you work.

• How much force was used to push the box without wheels and axles? With wheels and axles?
• Which method of pushing was easier?

The spring scale may read 0 newtons used to move the box with wheels and axles. This does not mean that no force is being used. It simply means that so little force is being used that the spring scale is not powerful enough to detect it. You could always add heavier objects to the box to see if that would affect the force measurement.

Why did you repeat the experiment with three trials? Repeating trials improves the reliability of the results. For example, by doing three trials, a scientist can look at his or her results to see if the measurements all look similar. If one measurement is different from the other two, something may have gone wrong.

Did you demonstrate work in this activity? Work was only accomplished if the box ended in a different position from where it began.

Gather the materials necessary to do the Elaborate, Part 2 activity. Read through the Advance Preparation and Content Builder in the lesson. Follow the directions in Teacher Instruction to do the activity.

Keep the following questions in mind as you work.

• How much force was used to raise the water bottle without the pulley? With the pulley?

The amount of force should be the same because you are only changing the direction of the force. If you are measuring a higher amount of force using the pulley, there may be friction in the system between the pulley and the rope.

• Does it feel easier to pull the bottle straight up or to pull the rope down using the pulley?

It should feel easier to pull down because you have gravity and the advantage of your body weight working in your favor.
