Lesson title: Surface Area and the Solar Cell
Lesson Objectives:
1.The student will draw an illustration of a solar cell (PV CELL) and explain how energy is produced.
2.The student will draw an illustration of a solar cell (Dye Sensitized CELL) and explain how energy is produced.
3.Students will design a building that incorporates solar panels to produce energy.
a.The student will use graph paper to draw their Blue Print.
b.The student will use geometric shapes in the design of their building.
c.The student will give the total surface area of the design of their building.
d.The student will give the total surface area of the part of the building that is covered by the solar panels.
e.The student will give the ratio of the Total surface area of the building and the Total area covered by the solar panels. R = Total surface area of the building
Total area covered by the solar panels |
f.The student will give an itemized cost of the solar panels. This will be found by researching the internet. This information will be listed in a spread sheet. The spread sheet will include
Dimensions (area) of each solar panel, watts per solar panel, price per solar panel, state tax if any, total cost of all solar panels purchased.
