Learning Goal: To understand the relationship between work and energy, and use it to predict the motion of objects.
Today:

Find: The height from which a mass on a spring must be released in order to just touch the egg without breaking it. Cracking is acceptable, but leakage = fail.
You are not allowed to let any masses fall on the spring until your actual trial. Before you will be given your trial mass, you must your work for determining the spring constant, including any graphs. Before your actual trial, you must show the work behind your prediction, including LOL charts.
