What should the reader know or understand when he/she is finished reading the report?
The purpose of this lab is to observe the conservation of momentum and energy in one dimension in a real life setting. We will study this concept through the motion of carts colliding on a track. The velocity for one or two carts will be determined before and after their collision.

Statement of purpose (in intro) should be reflected in conclusion
Overall this lab was a success. The purpose was to observe the conservation of momentum and energy in one dimension in a real life setting. The study of this concept was accomplished through the motion of carts colliding on a track. In addition, the experiment determined the velocity for one or two carts before and after the collision. During the course of the experiment the conservation of both momentum and energy was noted, and the final velocities of the carts was accurately determined.

“The Debye-Sherrer method identified the sample material as nickel due to the measured crystal structure (fcc) and atomic radius (approximately 0.124nm).”

After adding the solution, the mixture in the test tube went a bright scarlet red, which we did not expect, as this was not the same as the washed out pink colour it was supposed to go according to the book. We shook the test tube up and left it for awhile in the test tube stand. When we came back, the mixture had settled to the bottom and dried out, which it was not supposed to have happened; this was a bit of a problem.
