Unit Study: Stars

This was actually from a couple of weeks ago, but I forgot to post it…

We spent one week on learning a little bit more about stars. I kept it pretty light and pretty much only did the things in the MFW manual, only adding in some more books and I think one activity (that didn’t turn out).

Books we Read

Discussion, Experiments & Journaling

We talked about the distance that light travels. We talked about how it takes 2 seconds for light to get to earth from the moon. It takes 8 minutes for light to reach earth from the sun. And it takes 4 years for light to reach us from our closest star (Proxima Centauri something). I explained to Treyton that that meant that the light that came from Proxima on the day that Lexie was born has not even gotten to earth – we haven’t even seen it yet! Treyton thought that this was pretty amazing.

We tried to illustrate this in Treyton’s science journal.

Next we talked about the biggest star we could see from earth (with a telescope) called Betelgeuse. This star is 600 times bigger than the sun. We cut out a 1 inch circle which represented the sun and had Lexie hold it on one side of our yard

IMG_0196we then measured out 600 inches (16 3/4 yards) and had Treyton stand there. This was a humbling illustration showing just how small the sun (and in essence we really are)!!

Completed Lapjournal Pages

We took our handouts from our MFW Co-op: Stars and added them to our science journal.
