Tuesday 3-17-20
By Friday 3-20-20 email me a picture of your Animal Cell Coloring Sheet and a picture of your Plant Cell Coloring Sheet (just the side that you colored).  Use the questions to help you review for the upcoming test (Test will be Tuesday). 

Also by Friday, complete your scientific write up for the Grape Activity and email it to me. 

If you are unable to email me photos of the coloring sheets and the grape activity write up then leave me a message at the school and we will arrange an alternative delivery technique.

If you are able to and still want to work with all or some of your Grape Activity group members then you can.  You should include the following in your Grape Activity Write Up (fill in any missing parts and create and complete the indicated data table):

Question:  What will happen to the mass of three grapes if one is placed in water, one in sugar water, and one in grape juice for 96 hours?

Hypothesis:  If one grape is placed in water, one in sugar water and one in grape juice for 96 hours then the mass of the grape in water will ___________, the mass of the grape in sugar water will _______________ and the mass of the grape in grape juice will _______________.  

(I was uncertain of the data for some of the groups so I would like everyone to use my data)

Create a Data Table for the following information:  

Initial Mass of Grapes:  Grape in Water  - 13.92g, Grape in Sugar Water  - 15.89g, Grape in Grape Juice  - 16.26g

Final Mass of Grapes:  Grape in Water - 16.05g, Grape in Sugar Water - 12.86g, Grape in Grape Juice - 16.26g

Analyze Data and Answer the Following Questions:

What kind of solution was each grape in (hypertonic, isotonic, or hypotonic)? 

Did each grape's mass increase, decrease, or stay the same? 

If the mass increased or decreased then by how much? 

Explain why the mass of each grape increased, decreased or stayed the same, by describing what happened with the movement of water into and out of the grape's cells.

One observation you might want to include is the final appearance of the grapes.  The grape in water was so swollen it burst in a few places, the grape in sugar water looked shriveled, and the grape in grape juice basically looked the same.

Conclusion:

When one grape was placed in water, one in sugar water and one in grape juice for 96 hours the mass of the grape in water  ___________, the mass of the grape in sugar water _______________ and the mass of the grape in grape juice _______________.  Therefore, the hypothesis was _______________.
