How do the plus or minus symbols help you decide whether something attracts or repels? _____________________________________________________________________________ _____________________________________________________________________________ c. Talk about how your observations support, change or add to your ideas from Question 1 and about what affects whether things attract or repel. Then revise your ideas from Question 1. 1 3. Test your ideas about attraction and repulsion using the Electric Field Hockey simulation in the Practice mode. https://phet.colorado.edu/en/simulation/legacy/electric-hockey Play with the sim and think of ideas that help you SCORE! Now, develop strategies for the following challenges: Make a GOAL where puck takes the SHORTEST amount of time to get to the goal Make a GOAL where puck takes the LONGEST amount of time to get to the goal Draw your strategy for placing positives or negatives in the picture below. Draw your strategy for placing positive or negative pucks in the picture below What rules are you using to determine which direction the puck moves? _______________________________ _______________________________ _______________________________ _______________________________ What rules are you using to determine which direction the puck moves? _______________________________ _______________________________ _______________________________ _______________________________ What rules are you using to determine how fast the puck moves? _______________________________ _______________________________ _______________________________ _______________________________ _______________________________ What rules are you using to determine how fast the puck moves? _______________________________ _______________________________ _______________________________ _______________________________ _______________________________ 2 4. Draw where you might put pucks to get a goal with the fewest pucks. Explain why this works: ____________________ ____________________ ____________________ ____________________ ____________________ ____________________ 5. Reflect on your ideas from Questions 1&2 and your data from Questions 3&4. How do your observations support, change or add to your ideas about… …whether two objects will attract and repel? …how strongly they attract or repel? Revise your explanation from Question 1. 3

2. Let’s look at the Balloons and Static Electricity simulation below.
https://phet.colorado.edu/sims/html/energy-skate-park-basics/latest/energy-skate-parkbasics_en.html
a. Explore the simulation.
How can you make the balloon stick to the sweater?
Rubbing the balloon against the sweater
b. What makes it stick weakly versus strongly?
Number of rubbing time
c. How do the plus or minus symbols help you decide whether something attracts or repels?
If there are same symbol (plus or minus) then it repels. If there opposite symbols (plus and
minus) then it attracts.

d. Talk about how your observations support, change or add to your ideas from Question 1 and
about what affects whether thi...
