3. Day 2: Scientific Method Practice: Writing an Introduction
You’re the Chemist!
The following small-scale activities allow you to develop your own procedures and analyze the results.
Design It! Design an experiment that will determine the number of atoms of calcium, carbon, and oxygen it takes to write your name on the chalkboard with a piece of chalk. Assume chalk is 100 percent calcium carbonate, CaCO3.
