Learning Goal(s):
1. Students will explore the role of series and parallel wiring as they pertain to voltage and amperage. 2. Students will explore the processes involved with charging batteries and relate these processes to voltage and amperage. 3. Students will test photovoltaic modules to identify voltage and amperage outputs. 4. Students will design a system of wiring 3 V, 1.5 A modules together as a means to charge a 12 V lead-acid battery 5. Students will predict and test the effectiveness of their designed solar charger.

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.
