Egg lab again (pgs 72-74) & argumentation session

Summaries for this week go on pg 75


You should have the mass of the egg recorded on pg 72 (in a table) as well as observations of the egg before and after it is placed into the vinegar, and observations (including mass and volume) of egg after vinegar and before syrup


Day 6 of egg lab –

1. Observe the egg. Record your observations.

2. Carefully remove the egg from the beaker. Be EXTREMELY careful. The egg is very, very fragile now.

3. GENTLY rinse the egg and find its mass. Record.

4. Using a beaker, calculate the mass of the syrup left in the cup.  Record.  Also, record what they syrup looks and smells like.

5. Rinse the cup

6. Pour water into the cup up to the 90mL mark (the one from the vinegar)

7. GENTLY place the egg into the water
