Egg Demonstration of Diffusion and Osmosis

After Leaving It Out Overnight

After leaving the egg out overnight, they began to shrivel up and decreased in size. The outer membrane became lose on the inner substances.

Conclusion

Procedure

In this extra credit experiment, I discorved the different ways the eggs can react in other liquids. It helped me understand the effcts of different types of solutions: isotonic, hypotonic, and hypertonic. It really showed ways the cell membrane works.

Luandy Detergent

1. I chose my two liquids to soak my eggs in after the eggs are soaked in vinigear to get ride of the shell.

2. After placing the eggs in vingear taking the measurements before, 500 ml of vinigear, and after leaving them out for 24 hours. Making observations and taking pictures.

3. Next I measured 500 ml of olive oil and placed the eggs in. Then I left it over night. Then I removed the eggs making observations and recording results of the left over liquid after the eggs were removed.

4. Lastly I placed the eggs in detergent over night after measuring exactly 500 ml. Then after recording observations and measurements, I removed the eggs.

5. I placed them on the counter overnight and made observations.

Hypothesis

Before

-I measured 500 ml of detergent.

After

-I was left with a little over 500 ml of detergnet.

Observations/Results

-The eggs decreased slightly in size. The detergent also seemed to break down some of the remaining protien.

-I decided to test my two eggs inside of olive oil and laundry detergent after soaking it in vinigear.

-I predicted that the olive oil will cause the eggs to expand. I predicted the detergent would cause the eggs to shrivel up.

Olive Oil

Before

-I measured the 500 ml of olive oil .

After

-I was left with 500 ml in the end.

Observations/Results

-The eggs stayed the samed cuasing it to seem like an isotonic solution.

Vinegar

Before

-Measured 500 ml of vinigear.

After

-450 ml of vinigear were left.

Observations/Results

-The eggs swelled and their sheels brokedown.
