Objectives:
1. To apply basic knowledge regarding the measurement of mass, length, volume, temperature, and density
2. Learning to identify and use tools provided within the labpaq kit
3. Becoming familiar with common lab tools used in Chemistry
Observations:
While participating in experiment 1, I was able to become familiar with my new lab kit. I observed how to weigh and measure objects as well as record those findings in an organized graph. Throughout the lab I was able to measure using a ruler, all the way to measuring volume.
