2. Peer Grading on Lab Activities
If I correct you for goggles or staying on task ONE time = 3.75
If I see you off task; wandering to other groups (no 4)
If you are on your phones (no 4)
The sheets are confidential and 4 should be hard to obtain
Make sure you are also keeping track of what everyone is accomplishing so you can justify your responses to the grading
I will not accept your sheet if you do not have your group member’s names on them.

3. Turkey Sandwich #1 Bread Turkey Swiss Avocado Mayo Salt Pepper
Oil/vinegar

4. Turkey Sandwich #2 Put mayo on bread
Put oil and vinegar and salt and pepper on bread
Add the turkey, avocado
Cut in half
Clean up
Put on plate

5. Turkey Sandwich #3 Combine Mayo, oil, and vinegar together
Dip turkey in mayo,oil, and vinegar
Place on a piece of bread
Put one slice of cheese on top
Dip butter knife into avocado and spread onto both sides
or cut it in half and put one half on top of turkey
Pour oil/vinegar on top
Slap the other bread on top and smush together

6. Turkey Sandwich #4

7. Remove two sliced of bread from bag
Lay two slices of bread on a clean surface
Open the mayo jar by twisting the lid c.c.w
Using a teaspoon measure out one tsp of mayo
Spread the 1 tsp of mayo on one flat side of one piece of bread
Place 3 slices of turkey on to the mayo bread
Add one slice of swiss onto the turkey
Carefully cut open the avocado, by using the knife to cut the avocado through the skin and around the pit
Then twist the two sides of the avocado in opposite directions and separate them
Remove the pit
Take one of the separated sides of the avocado and use the butter knife to cut it into approximately ¼ inch slices.
Use a spoon to scoop out the avocado slices
place 3 avocado slices on top of swiss (on sandwich)
Add 1 tsp of oil and vinegar to the flat side of the other piece of bread
Dash the avocado with a pinch of salt and pepper
Place the final piece of bread on top of your other slice
Cut in half
Eat
Clean up

8. Update your TOC Call Activity: Density Learning Target:
I can explain the concept of density

9. DENSITY
Lab safety
video-rap
Get into your groups at a table first
Lab Roles within the group
In your groups of four divide into pairs
One pair will see what sinks and floats with solid/liquid
One pair will see what sinks and floats with both liquids
Decide on roles
Create a table with your hypothesis

10. Materials Solids: Hex nut Chalk Lego Paper clip Pencil Cork Nail Rock
Liquids:
Corn oil
Corn Syrup
Baby Oil
Isopropyl Alcohol
DI Water

11. Create two tables: Liquid v Solid
Corn Oil
Corn syrup
Baby Oil
Iso Alcohol
DI Water
Nut
Chalk
Float
Lego
Paper clip
Sink
Pencil
Cork
Nail
Rock

12. Create two tables: Liquid V Liquid
Corn Oil
Corn syrup
Baby Oil
Iso Alcohol
DI Water
Corn Syrup
Syrup bottom?
Baby oil
Corn Syrup

13. With your lab group test your hypothesis
You need an identical tables from yesterday as you will be determining which solids and liquids sink and which will float
Once finished start planning out your density column
Begin testing and writing procedures for your successful column
no nasty turkey sandwich procedures as you will not be performing these procedures
RECORDER: once you have a successful set of procedures you must copy them down on a separate sheet of paper for the other group (and me)
be sure that everyone has it all recorded in their own NB

14. Your Goal
With the materials provided you will create a density column.
