For this Lab we used different materials like ruler, colorful filters, a lighter, and a NXT with a light sensor. The purpose of this lab was to observe the relationship between the light and the voltage. Fist we measured the voltage with no filter at a 20 cm distance, then at 23 and 30. the computer run the process 10 times. Then i did the same thing with the color filters, for this process i measured the voltage with 3 different colors those being Red, Blu, Magenta at the same distance (20 cm). 
After finishing this process i graphed the data, the first graph was voltage and distance, and the second graph was voltage vs Color filters.
From the results the red color had the highest intensity. To perform this project we used Data lab view in our classroom computers.
Solar Panels are a good source of energy because the produce energy by observing sun light, also is a non-pollution power, it can be build in remote areas.
Even though Solar panels can be very helpful the environment they are very expensive to be build, and also can work well when is sunny and day time, which doesn’t apply to the Massachusetts New England Weather.
