This document summarizes an experiment on osmosis using eggs in corn syrup and water. The student hypothesized that the corn syrup egg would gain weight and size and look shiny, while the water egg would lose weight and stay the same size. The observations showed the corn syrup egg lost weight and shrank while the water egg gained weight and increased in size. In conclusion, the hypotheses for the corn syrup egg were incorrect but correct for the water egg.

EGG OSMOSIS EXPERIMENT

2. • To observe osmosis in a cell.
1)Place eggs in vinegar to remove the cell.
2)Measure it’s weight.
3)Measure it’s width.
4)Place egg in water and corn syrup.
5)Weigh and measure it again.
PURPOSE

3. • Corn Syrup:
I think the egg is going to get
heavier for it’s weight.
I think that the egg will get a
little bit bigger for it’s size.
I think the egg will look shiny.
HYPOTHESIS

4. • Water:
I think that the egg will get
Lighter.
I think that the egg will stay
the same size.
I think the for the eggs look
will be the same.
HYPOTHESIS

5. • Corn Syrup
• Water Vinegar
• Balance
• String/Measuring

10. PAINT DRAWING

11. • My Corn Syrup hypothesis is wrong:
• The egg got lighter than heavier.
• The egg got smaller, not bigger.
• The corn syrup egg looked different because it looked all squishy and I
said it would look all shiney.
• My Water Egg hypothesis:
• The egg got heavier, not lighter.
• I thought the egg would stay the same size, but then it got larger.
• The water looked the same just like what I said.
