…What’s my angle? – We’ve used a little Solar geometry to analyze and estimate the proper angle for the tilt of my Solar panels. Should I tilt the panels on my roof to more accurately aim towards the Sun? If so, at what angle should I use? Should I be able to adjust the panels to better receive low winter Sun and high summer Sun? How do I figure all of this out? 7.G.B, 8.EE.B, HSG.CO, HSG.SRT, HS.TF, HS.C, MP2… 0, 11

## Total solar eclipse – apparent sizes

…seem to cover the sun completely? We’ve created a pretty extensive investigation about the geometry of a solar eclipse and the apparent size of both the moon and sun as seen from the earth. This activity can be done with or without trigonometry so it is appropriate for students 6th grade and higher. Get your students ready. Never look directly at the sun without ISO and CE certified solar eclipse glasses. The activity: 2017SolarEclipse.pdf CCSS: 6.RP.3, 7.G.1, 7.RP.2, HSG.SRT.C.6, HSG.SRT.C.8,… 0, 6

## HDTV Surprise!

…were your holidays? Your school vacation? Mine was good. I surprised my family with this HDTV, which I wrapped and hung on our wall. The size of an HDTV is determined by the length of its diagonal. What size HDTV could this be? Knowing that HDTV dimensions follow a 16:9 ratio (L & W), do you think this could be an HDTV? No scale is provided, how can you make your own? Note: This task can be solved with or without the use of the Pythagorean Theorem. CCSS: 7.G.1, 7.RP.3, 8.G.7, HSG.SRT.C.8… 0, 2
