Task 3: Set up page for tomorrow's lab (7 minutes)
1) Record the title (Lab: Static Electricity) and date (W1, D2) at the top of page 90
2) Record these notes at the top of the page: Notes: Protons have a positive (+) charge Electrons have a negative (-) charge. Atoms are usually neutral (no charge). Different charges attract (pull towards each other). Same or "like" charges repel (push away from each other).
3) Record the sentence starter for the hypothesis. Do NOT complete the sentence yet. Hypothesis: If I rub two objects together, then...
4) Make a chart for your observations. Leave several blank lines so that you can describe what you see at each station. Observations:

Task 1: Lab - Exploring Static Electricity
Here are the directions for the lab. Be sure to record observations at each station - Example: when we did [blah], then [blah blah blah] happened.
Procedure:
Station 1: Balloons and Hair
1) Rub the inflated balloon vigorously back and forth across one group member’s hair.
2) Record what happened to the group member’s hair.
3) Touch the balloon to one of the side walls and let go of it (try a few surfaces if you have time).
4) Record what happened when you placed the balloon to the wall.
Station 2: Charged Rod and Water
1) Turn on the faucet so that the water runs out in a small, steady stream.
2) Rub the rod with the piece of fabric to “charge” it.
3) Bring the rubbed end of the rod near the water (do NOT touch it) and observe how the water behaves.
4) Record what happened in your chart.
Station 3: Cereal and Charged Rod
1) Place some pieces of cereal on the lab desk.
2) Rub the rod with the piece of fabric to charge it.
3) Slowly bring the rubbed end of the rod near the cereal.
4) Record what happened in your chart.
Station 4: Charged Rod and Styrofoam
1) Place some Styrofoam pieces on the lab desk.
2) Rub the rod with the piece of fabric to charge it.
3) Slowly bring the rubbed end of the rod near the Styrofoam making sure not to touch it.
4) Record what happened.
Station 5: Balloons
1) Rub the balloon against a group member’s hair to charge it.
2) Move the charged balloon towards the other balloon.
3) See what happens to the other balloon. Record what happens in your chart.
4) Now charge both balloons. 5) Put them next to each other to see what happens. 6) Record what happens in your chart.
Station 6: Charged Rod and Paper

Task 2: Explaining Static Electricity 1) Title page 93: Explaining Static Electricity 2) Divide the whole page into 6 boxes 3) Label the boxes 1-6 4) Box 1: Copy the two definitions below Electricity happens because of the presence and movement of electric charges. Static electricity is the build up of these charges in an object. 5) Box 2: Record at least three examples of static electricity in everyday life and draw a picture for each. 6) Go through the following presentation to complete boxes 3, 4, 5, and 6 Box 3: Atoms vs. Ions Box 4: Electric Charges Box 5: Electric Fields Box 6: Law of Conservation of Charge
