Physical and Chemical Change: (Static Electricity)

Launch: Yesterday we discussed static electricity and how there are different charged particles that are a part of static electricity. Can anyone tell me those particles? Positive and negative charged particles. Exactly. We are going to continue our investigation with static electricity. Today we are going to discuss how sometimes you can SEE that reaction occur when positive and negative charged particles are in contact with each other.
-Tap into background knowledge with balloon on hair demonstration. Aim to have students suggests that the hair is sticking up to the balloon because of static electricity. We can SEE that reaction happening.
Our focus question today is…
Focus Question: What happens when we rub a plastic spoon on cloth and hold it closely to the salt and pepper?
Turn and talk with your table group about your prediction of what you all think may happen with the salt and pepper when its put close to the rubbed spoon. Please have one person from your table group come write your prediction on the board.
Read If/Then predictions off of board.​

S & P: Static Electricity

Prediction: If we use static electricity, then we can separate the salt and paper.

Data Chart:

             Materials:                                                                                    What Happened:

Bowl

Salt

Pepper

Plastic spoon

Carpet

*What Happened: The salt and pepper stuck to the spoon. There was more pepper than salt that stayed on the plastic spoon. As we moved the plastic spoon closer to the salt and pepper more would stick. 

Claims/Evidence:

If we have salt and pepper mixed together, then we can use a plastic spoon rubbed against cloth to separate the two variables.

Conclusion:

Is there another item we could use to demonstrate static electricity?
