So, okay, sidebar. If you have a slightly anxious four year old prone to worrying about things, don't go talking about solar storms unless you really know what you are talking about. Because if you don't you will end up backtracking, making stuff up, and finally, in response to your child's increasing panic, resort to declaring that the sun is a "shiny friend," and that a solar flare is, "the sun blowing us a kiss." So much for science! Don't even think of bringing up auroras! Where is the Magic School Bus story about the class visiting the sun when you need it?! We did look up some things on the internet and found a website that helped (a little), but there is probably a reason Kindergarten teachers don't go deep into nuclear fusion. Find a song for kids about the sun here.
There were lots of ideas included with the paper that would be fun to try; flowers, buttons, keys, lace, and even a film negative (if we could put our hands on one). We will definitely be experimenting more with this, just as soon as I can convince Jo it's safe to go outside again.
