How Light Intensity Affects Solar Cell Output
Students will expose solar cells to a light source from different distances and measure the output with a multimeter. They will compare and contrast the outputs that the different distances produce.

Through a series of exploration and inquiry activities, students will explain kinetic molecular theory, atomic, and molecular structures. Students will be challenged to gradually increase the precision of their explanation of molecular-level structures...
This lesson begins with basic chemistry with regards to atomic structure. The lesson then moves to understanding the special properties of silicon as a photoelectric semi- conductor. Building on this, the basic structure of photovoltaic solar cells is...
Students will design a science investigation to test solar car with a pulley or with a variety of gear sizes. In the previous lesson, they were introduced to the different types of systems that can be employed on their car. In this lesson they will use...
This lesson is designed for one 30-minute session. After reviewing the hot/cool playground spots from Lesson 1, Students will be asked, “On a hot day, which materials might keep the ground the coolest?”. Students will be given tissue paper, photocopy...
This lesson is designed to span 2 days with 80-minute sections. On the first day, the teachers will challenge the students to assemble circuits with solar panels that can power up 1) a motor with fan, 2) a music-playing circuit, and 3) an LED. Students...
During this lesson students will learn about how electricity originates at an atomic level and that electricity moves through conductors and can be directed using circuits. Students will used guided reading techniques to explore informational texts and...
In this lesson students will experiment with everyday household items to make batteries. Students will use lemons, potatoes, pennies, and cola to make batteries, and compare the amount of voltage produced. These lessons can be expanded to test a variety of...
In this lesson, students will begin to explore the potential and challenges related to using photovoltaics to supplement the power needed to charge batteries in BEVs. Students will test a variety of wiring options related to series and parallel wiring....
Students will learn how to program the Basic Stamp to use information from two photoresistors to point a servo at a light source. This will be the first degree of freedom for the flower head.
