By

2. Question
 Can an egg float in salt water?

3. Hypothesis
 We think the egg will float in
salt water with 2 table spoons
of salt added.

4. Materials
 egg
 salt
a container
 measuring spoons
 measuring cup
 ruler

5. Procedure
 First were going to get a see through
container.
 Then were going to fill it with 3 liters of
water.
 Next were going to put 2 table spoons of
salt each time it doesn’t float. Then were
going to put the egg inside the container 3
liters full of salt water. Then were going to
see if the egg floats after each addition of
salt. Finally , were going to graph our
results.

7. Observations
2 tbs of salt 6 tbs of salt 10 tbs of salt
14 tbs of salt 18 tbs of salt

8. Observations
 First we added 2 tbs of salt it didn’t float.
 Then we added 4 tbs of salt it didn’t float either.
 Next we added 6 tbs of salt still doesn't float.
 We added 8 tbs of salt didn’t float.
 We added 10 tbs of salt didn’t float.
 We added 12 tbs of salt it floated 1cm.
 We added 14 tbs of salt it floated 1cm.
 We added 16 tbs of salt it floated 2cm.
 Finally we added 18 tbs of salt and it floated 7cm.

9. Conclusion
 Our hypothesis was partially correct, the
egg did float in salt water but with 18
table spoons.

10. Research
 Objects sink in liquids when their density
is greater then the liquid they are in.
Water that has salt in it is denser. This
helps to keep less denser material
floating.
