Lesson 5: How Do We Evaluate Energy Sources?
Grades:
912

Lesson 5: Solar Mobile Design Challenge  Construction
Grades:
68
Learning Goal(s):
Students brainstorm ideas and share with their group.Students draw and label Solar Mobile designs in Engineering Notebooks. Students research an aircraft to trace (if this was not accomplished in the Center of Gravity lesson) and trace the aircraft outline onto foam board. Students construct a solar circuit to power motors and propellers on a foam board aircraft and test multiple times before adding to the solar mobile stand. Students construct solar mobile stand and add their aircraft to a dowel attached to the central hub. Students work with a partner to balance each aircraft onto the mobile. Students test the mobile speed outside (depending on weather) and compare to speed under indoor light stands. After initial testing, students redesign circuits or mobile construction to optimize design. Students use handheld devices to film their moving Mobiles to judge the machine’s speed. Students demonstrate how their Solar Mobile works and justify in writing why their mobile should be chosen for the Children’s Technology Museum.

Lessons 2: Exploring Circuits and Optimum Power
Grades:
68
Learning Goal(s):
Students build series circuits using “grain of wheat bulb” and LEDs powered by various low voltage solar panels. Students build parallel circuits using grain of wheat and LED bulbs powered by various low voltage solar panels. Students demonstrate and draw the energy transfer using solar energy. Students draw a circuit diagram of their final optimal circuit. Students design an optimal circuit model that will be used in their final project.

Learning Goal(s):
Students will apply Ohm’s Law. Students will use a multimeter to measure current, voltage, and resistance. Students will use a breadboard to set up a series circuit. Students will read circuit diagrams. Students will calculate times for an RC circuit to change state. Students will prove that resistors in series have an equivalent resistance equal to their individual sums. Students will program the Basic Stamp to measure voltage levels in a voltage divider and RC circuit.
