2. What is the effect of solutions with different concentrations on the size of an egg yolk?

3. The Experiment

4. 5 cups of water
5 egg yolks
sugar
Materials

5. Instructions Take 5 beakers Add a cup of water to each
Add an egg yolk to each
Add 0-4 tablespoons of sugar to each
0 tbsp to the first beaker, 1 tbsp to the next, 2 tbsp to the next and so forth

6. Hypothesis

7. We think the egg yolks with sugar will shrivel up and decrease in size.

8. Hypothesis support
The sugar will absorb the egg yolk and make the egg yolk decrease in size and the egg yolk with no sugar and just water will increase in size.
We think this is what’s going to happen because…

10. This is the progress Day 2 Day 1 No sugar 3cm 1tb 3½cm 2tb 3cm 3tb 4cm

11. The progress
Day 4
Day 3
No sugar 4cm
1tb ½cm
2tb ½cm
3tb cm
4tb cm
No sugar 4cm
1tb ½cm
2tb cm
3tb cm
4tb cm

12. Conclusion
In the end, the egg yolk with the most amount of sugar got the smallest and the egg yolk with no sugar stayed the same. We now know that egg yolks will shrivel up with sugar.
