Notes for teachers
I gave 10 minutes at the end of the model lesson to create a lab and then had a google survey to give me their ideas.
Then I made a lab sheet with their ideas of 5 different angles of the solar panel and measuring voltage to find the best angle to get the highest amount of voltage.
I made a Google survey for data collection for a class discussion

Science and Engineering Practices
Objective(s):
Today the students will have a group discussion and then design an investigation to increase the efficiency of the solar panel. Using a solar panel, protractor and multimeter.
Conduct an investigation of the efficiency of 5 different angles of the solar panel by measuring voltage.
Agenda (55-75 minutes)
Pre-Investigation & Video 10 minutes
Investigation 30-40 minutes
Intro/Driving Question/Opening
How can we increase the voltage production of a solar panel using a protractor and mulitmenter?

Assessment
Looking at their data, were they able to come up with 1 angle that would be the best.
Differentiation
Walk around and help students setup and angles to make sure they are getting good data.
If cloudy that day or if you have students that are sun sensitive have a heat lamp setup in the classroom so they can still complete the lab.
Remediation
Extension/Enrichment
Have the students analyze and explain the different hours data collection in the Google survey.
Make a prediction about different seasons and amount of voltage.
