Do you think his evidence is strong? Why or why not?

"I (do/do not) think this is a strong source of evidence because ... "

Think: how similar are test 1 and 2?

How can you tell or predict whether two magnets will attract each other, repel each other, or both?

• Draw a pair of magnets that indicate attracting and repelling magnets

Evidence Card D

Evidence Card A

Evidence Card B

Evidence Card C

Do Strong magnets repel, and weak magnets attract?

•   Yes

•   No

Write: What evidence do you have to support your claim that, Yes- Strong magnets only repel, and weak magnets ony attract. Or No- Strong magnets do not always repel, and weak magnets do not always attract.

CFS:

• Accurately describes the relationship between magnetic strength and movement of magnets in a system

• Accurately identifies the strongest sources of evidence in a text

"I think:

- Strong magnets ony repel, and weak magnets only attract

OR

- Strong magnets do not always repel, and weak magnets do not always attract

I think this because according to evidence card (___) .... "

Goal: Create two models. In one model, show two magnets that will attract. In the other model, show two magnets that will repel. Use the symbols shown in the Key in your models.

Do:

      Write the definition of attraction and repulsion

      In the left panel, draw two motionless magnets positioned so that a magnetic force will cause motion.

      In the right panel, show what would happen to the magnets after you let them move freely.
