Activity 2: Maximizing Power Output in a MudWatt
In this investigation you are trying to nd ways to modify the MudWatt so that it
will produce the greatest amount of power. Your team will have two MudWatts.
Both MudWatts should be identical except you will change one thing in one of the
MudWatts.
What can you think of to change? Use your imagination. Create a competition with
another group to see which group can produce the highest amount of power!
