The experimenting has died down in a sense because everyone is getting ready to go on Winter Break. Currently, we are planning on doing further experiments relating to our sunlight angles. After break, we will more than likely redo the Clinometers experiments if we need better accuracy, or try another form of experiment if need [...]
After performing our sunlight angle experiment with the Clinometers (I found out the proper name for them), we found the average sunlight angles. The average angle that sunlight hits our school from the West is 20°. The average angle East of our school is 30°. Using this data, we will know effective angles to set [...]
We have come to an agreement in class on what type of experiment to perform. In order to find the sunlight angles, we will be doing an experiment based on our 9th grade Geometry projects. We will have a viewing tube attached to protractors with sting and weights. As we look up to see the [...]
Now, we are in the midst of finding where the sun strikes the school at different positions. We are discussing how to set up an experiment that will allow us to find the angles that sunlight hits SLA with relative accuracy. Since there are many other buildings around the school, many taller in fact, we [...]
We’ve done a lot since I’ve last spilled my brain leakage into the internet database to be processed around the globe by possibly millions of viewers, or maybe just one who gets bored enough to take a gander in this direction. As a class, last time I posted, we had decided to divvy ourselves into [...]
It’s about two months into the school year, and we’ve working on the same thing for about the whole of October. I can sense VanK’s frustration at our tiny little baby steps, as class is devoted more to doing the homework we didn’t do than actually analyzing the homework that was supposed to be completed. [...]
For our classwide engineering project this year, we are supposed to investigate a types of solar cells that we could use in our attempt to derive energy from the sun. Each of us did research, and three major types of solar cells were identified. Copper w/ H2O, Silicon, and Titanium Dioxide w/Rasberry. As a class [...]
During our engineering period, we experimented with small solar cells to see what we could accomplish. My group worked with reflecting the sun on to the cells to see if it could help with anything. However we did not have mirrors so we used aluminum foil. The group and I set the solar cell up [...]
On the 14th, we got solar cells! Exciting. They came attached to motors, and we got pull them apart. This day was mainly attempting to attach them in series and then in parallels to see if there is a difference in the energy output between the two ways to wire them. This did not go [...]
Students will find this article very entertaining & educational. (Al Gore has a “gotcha” moment). What do the Phillies, the Zoo and carbon offsets have in common, anyway? It was written by John Steele, in the online version of the Philadelphia Weekly. Bob Simon Digg this post Recommend on Facebook Share on Linkedin Share [...]
Solyndra – What’s really at stake
