Objective(s):

1. Students observe and explain the affect of solution concentrations on cell membranes. 

Today's lesson:

1. Students made shapes with black paper and we paper clipped them on to a geranium plant to do an exeriment with photosynthesis [we will follow up with this in a week.]
2. Students use spectrophotometer to take measurements with the purpose of determining relative concentrations of different sugar concentrations.

3. Student	Dish & sugar mass	dish mass	brown sugar
   Monica	11.558	2.331
   Eunji	10.139
   Rachel	ab	ab
   Yeana	8.388	2.178
   Jamie	4.381	(used Monica's?)
   Jamie	-	-	4.00
   Terry	ab	ab

• Record the data (measurements) you made so you can replicate or refer to this later.
• Place the solution into a thistle tube; cover mouth with membrane & elastic; mark height of fluid; place in beaker of filtered water - above bottom of beaker
