PROBLEM:
HYPOTHESIS:
DAY
1:
·
Observe
each egg
·
Find
the mass of each egg
·
Put
two eggs in a beaker
·
Add
enough vinegar (acetic acid) to the beaker so that you are completely covering
the eggs. Be sure to record the amount of vinegar that you use.
·
Make
detailed observations.
DAY
2:
·
Make
detailed observations.
·
Pour
out the vinegar and find the mass of each egg again.
·
Make
observations.
·
Put
Egg A in a beaker and completely cover with distilled water. Be sure to write
down the volume of the water. Make observations of both the egg and the
material it is submerged in.
·
Put
Egg B in another beaker and completely cover with corn syrup. Make observations of the egg and the material
that it is submerged in.
DAY
3:
·
Make
observations of what the eggs look like after sitting in the water and syrup
over night. Observe both the egg and the
substance that it is in.
·
Pour
off the water and the syrup and find the mass of each egg again. Handle the eggs carefully. Make more observations.
