Make sure to rinse the egg shells before using them in the science experiment. 2 Fill one glass with water, one glass with soda pop and one glass with vinegar. Take a picture of the three glasses to show what the egg shells looked like at the beginning of the experiment. 3 Allow the glasses to sit for one week. Record what you see each day. Use a composition notebook to record your findings or use an observation form. On an observation form, describe the procedure, make a prediction and record any observations. 4 At the end of one week, take another picture. Record any final observations.
