Learning Goal(s):
Students will follow step-by-step instructions to build their solar boats. They will troubleshoot as necessary by making sure electricity flows into the motor to make the vehicles move by propeller or gears. Students will determine different data points that are useful in the determining the most effective design for a solar powered boat. Students will undergo the process of redesign, noting why they made changes to particular variables on their boat and noting how these changes played out.
