Monday

A very strange thing happened last week. I had meetings after school on Thursday and didn't get this written. But I went straight home and typed it up. I am not sure why Thursday isn't on this blog, but it is not. So, on Thursday we learned about light and the electromagnetic spectrum. It is amazing the gifts we receive from this spectrum, visible light, radio waves, x-rays. We discussed frequency and wavelength, and that visible light is just a very tiny part of the spectrum. In fact we were told that if we took the old movie film and stretched it 2500 miles, from California to Alaska, visible light would only take up one frame! That is just amazing.

On Monday we learned about the sun. We learned how it causes seasons and the aurora borealis. We differentiated between the earth rotating and revolving. We discussed time zones and how we got them. Then we watched an interesting video that showed the sun in comparison with other planets and stars, now that is just fascinating!
