Learning Goal(s):
Students will be able to describe, in basic terms, the way that electricity is generated from a solar cell. Students will be able to determine that energy from the sun is being converted directly into electricity. Students will understand that this electrical energy that is produced in this energy transfer is able to perform the work required within a small load.

Solar Updraft

Let's Build Our Wind and Solar Energy Toy

Grades:
3-8
Lesson Number:
4
Description:

Students will combine what they learned in previous lessons using their investigations of convection-related phenomena to design a device that will convert light energy from the sun into thermal energy and utilize the resulting convection currents. Their...

Learning Goal(s):
Students will determine that thermal energy resulting from the sun’s radiation can create an updraft that will power a turbine to spin.                                                Students will identify characteristics of turbine design that improve the success of their device.Students will utilize content from previous phenomena they investigated, such as the chimney stack effect and Norwegian candle toys, to determine how to best harness the energy transformed by their device from the sun.

Solar Mobile

Solar Mobile Design Challenge - Construction

Grades:
6-8

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 hand-held 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.
