Use Google Slides.

Find out the following for your slides and create slides for each.


Slide 1: Title: Energy

Slide 2: Energy. Define it and find a representative image.

Slide 3: Potential Energy. Define it and find a representative image. Show the equation somewhere.

Slide 4: Kinetic Energy. Define it and find a representative image. Show the equation somewhere.

Slide 5: Conservation of Energy. What does it mean? Find a representative image.

Slide 6: What are the SI units energy?

Slides 7,8: Find 2 different examples of potential energy, find an image, and explain why each is a good example.

Slides 9,10: Find 2 examples of kinetic energy, find an image, and explain why each is a good example.

Slide 11: Find an example of potential energy being converted to kinetic energy and include an image of it.

Slide 12: Find and example of kinetic energy being converted to potential energy and find an image of it.

Solar Power Lightning Paper

posted Apr 15, 2016, 10:39 AM by Tony Farley   [ updated Apr 15, 2016, 2:02 PM ]



Lightning because it's fast

Write a lightning fast paper about ONE thing you learned about solar power.

Use whatever info, graphs, measurements, or calculations you have to write a short paper about some aspect of solar energy that we learned about. You can find info and a topic from your comic, your measurements using solar panels or your access to the school's solar data. Concentrate on ONE aspect, not the overall learning.


Think one or two sentences per section. Graphs or images are great as well.

Analyzing the School's Solar Energy System

posted Apr 11, 2016, 10:41 AM by Tony Farley   [ updated Apr 14, 2016, 12:44 PM ]

You will be looking at SLHS's solar energy systems today. Answer the questions on this document as you follow the directions.


Go to https://www.sunpowermonitor.com/partner/partner.aspx#

Login with Username tfarley@slusd.us
and Password: I'll tell you what it is.

You will see this when you login

1. You will see that we can monitor SLHS's solar system as well as John Muir's. How much energy was created today by each system?

2. Double-click San Leandro or click it and then click "Open in new window."  At the top right, you will see the Power coming from the system right now, today's total power, Temp, Wind speed, and Irradiance. 

What is your reading for all of these for when you logged on?

3. What does kW stand for? (don't just answer kilowatt-hour. Explain what a kilowatt-hour is.)
4. What does kWh stand for?
5. What does Irradiance mean?
6. What does W/m2 mean?

7. Reload the page. What has changed with date, time, Power, Today, This month, temp, wind, irradiance?

8. The next part of the screen shows you the power generation and energy production by each inverter. Find out what an inverter is and explain it.

9. The first column of data is Inverter SN. This stands for Inverter Serial Number. Each inverter has a serial number on it's side. The one pictured is 191212519 Here is a picture of one of the inverters along with a picture of its serial number.


Find the inverter pictured and list what it's Nameplate Capacity is, its peak power generation today, its energy production today, and its lifetime energy production is.

10. Next is the graph area.

The top right has tabs that will show one day of data (1d), 3 days (3d), all the way up to a year. Take a screenshot of the last seven days of data.


11. Placing the mouse pointer over a data point in the graph will show you the information being plotted. Find the date and time for the maximum power produced. What was the maximum power produced?
12. You can change what's graphed by using the drop down menus on the left. The colored text shows what is being graphed and if you select something and hit "graph now" it will be added to the graph. Look at today's (1d) Interval Energy Produced and delete everything else.


Screenshot the graph and describe what happened between 9am and noon. What could have caused this?

13. Find MET Station ACP2407 and select Avg POA Irradiance (W/m2) and add this to the graph. Find out what a MET station is and explain what this is showing.

14. Screenshot your graph and explain what is being shown and why it's happening.

15. Add Ambient Temperature to your graph, switch to viewing the last seven days, and take a screenshot of the graph.

16. You can also download the data to analyze yourself. Click the button on the right that says downloads and download the .CSV file.
What does .CSV stand for?

18. Open your .CSV with Sheets by opening a sheet and then File > Import. Be sure to check the box that says it is Comma Separated (.CSV remember?). Select all the data and create a graph. Take a screenshot of the graph and put it in your document.



Turn your document in by filling out this form.

Solar Panels in Different Light

posted Apr 10, 2016, 5:08 PM by Tony Farley   [ updated Apr 14, 2016, 2:05 PM ]


Today we will explore solar panels in different brightnesses of light. 
Find the voltage across all 3 panels in Covered, inside classroom light, outside shade, and direct sun.

Graph your results using Google Sheets. A bar chart is best because you don't have x axis data, just use the words darkness, room lighting, shade, and direct sun along the x-axis.



Put all of your data and graphs on a Google Doc. Don't turn it in, you are going to add to this document tomorrow. You may work in groups of no more than 3.

Next day



1. Find the voltage across 2 small panels connected in series in the sun (or cloudy like it is today) Connect the red wire of one to the black wire of the other like in the picture.

3. Find the voltage across 3 small panels connected in series.

4. How many small panels does it take to match the voltage of a medium panel in the same light?

5. Find the voltage across two medium panels in series.

6. How many medium panels does it take to match the voltage of a large panel?

7. Voltage is only part of the story, each panels is labeled with its voltage, amperage, and power in Watts at maximum output. Find the maximum Watts our school's panels have put out on a sunny day. You need to find Max AC Power Produced. Remember kW means 1000Watts.

Go to https://www.sunpowermonitor.com/partner/partner.aspx#

Login with Username tfarley@slusd.us
and Password:Sunpower123

What is the maximum you found?

8. What's the Wattage rating on the large panel?

9. How many large solar panels does it take to make that much power?

10. The power of a panel is found by multiplying the voltage by the Amperage. P = VxA Find the power of a small panel. Remember that mA is milliamp. 1/1000 Amp.  How many small panels would it take to equal the power of one of the large panels?











Data Science and BIG DATA

posted Apr 5, 2016, 2:25 PM by Tony Farley   [ updated Apr 8, 2016, 1:02 PM ]

What's Big Data? Watch this video.

YouTube Video


We will be studying data from the school's solar panels. But before we do, we need to learn how to use and visualize LOTS of data.
Here is a screenshot of our online monitoring system showing the power output over three days:

To deal with large amounts of data we must learn about Data Science.

Data Science is the next big thing in all industries as well as universities. Go through the two hour data science curriculum below to learn about it. When you are done you will be able to download and print a Certificate of Completion to impress your parents as well as use in job and college applications.

"According to an independent study, Data Scientist is predicted to be the Best Job in America for 2016 with an Average Base Salary of $105,395!"

Enter this Teacher Code so I can keep track of your progress: K5QXUJBR

When you are done, access your Certificate of Completion and post it to your Energy page along with a paragraph or two description of what you learned. If you want to print it, let me know and I can print it to Mrs. Farley's printer.

Don't forget to post your comic to your website.
