Questions:
4. How did your final mass compare to your initial mass?
5. What happened to the atoms in the baking soda when you mixed it with the vinegar?
6. Were atoms created or destroyed during the reaction? Use evidence from the investigation to support

A.
B.
C.
D.
There are multiple ways to arrange the finite set of elements.
New elements are created as new materials are needed.
There are many electrons in each element.
Different molecular masses determine chemical combinations.
8. Connection to living things: How does your body get the atoms needed to build your growing muscles
and bones?
9. Squirrels eat acorns for energy and to grow and repair tissues. How is an acorn used to build squirrel
muscle?
A.
B.
C.
D.
The elements in the acorn can be rearranged to make the molecules the squirrel’s body needs.
The energy from the acorn warms any damaged muscle cells and allows them to heal.
The proteins found in acorns are the same as squirrel muscle proteins, so they attach to muscle cells.
Once the acorn has been digested by the squirrel, the carbohydrates are converted to muscle tissue.
