The document discusses how adding salt to water can change the density and allow normally non-buoyant objects to float. It describes an experiment where two eggs were placed in separate glasses, with one glass containing only water and the other glass containing water with added salt. As hypothesized, the egg floated in the saltwater glass due to the increased density from the dissolved salt.

1. Floating eggs

2. Question
•Does the salt make things float?
•We’ve heard that if you go to the Dead Sea you
float more than usual, but why does this happen?

3. Hypothesis
• We believe that because the Dead Sea
contains a lot of salt, it makes things float
and the density of water changes. So if
we add salt to a glass of water, it will
make things that are not supposed to
float, float.

4. Dead Sea
• In the dead sea there’s a lot of salt. There is such a big
amount of salt that there are no organisms living
there. The salt changes the density of water. It makes
it denser so you float. That’s the reason we’re doing
the experiment, to prove this.

5. Materials
•2 eggs
•2 glasses of water
•A pack of salt

6. Methods
We used:
-3 glasses
-Glass A 250ml of water
- Glass B 250ml of water
-Glass C 795 mg of salt

7. Results
-The one on the left has
salt, and the one on the
left hasn’t got anything
except water.

8. Conclusion
After doing the experiment,
we realized that is true, the
salt changes the density of
water. Our hypothesis was
correct.
