Today we learned a bit about light bulbs, as November 1 is the anniversary of the date Thomas Edison patented his design of the incandescent light bulb.
For a little craft I started with this image: http://www.edupic.net/Images/Science/light_bulb.gif
Cut out a frame from cereal box cardboard the same shape as the image.
Use a sharp cutter to trace around the black parts of the image and remove all the white.
Layer tissue paper under and over the cardboard, brushing it all with diluted white glue til it's all wet and stuck together. Add the cut-out of the light bulb and add more tissue on top if you want to. With the yellow bulb we did, with the purple one we didn't.
Let it all dry then trim to the shape of the bulb. Hang on a sunny window!
I gave the little ones this picture to color:
Meanwhile I went here:
to get a proper diagram of all the parts of a bulb and went through it with Cara.
For some interesting history, which may surprise you depending how thorough your own teachers were when teaching you about the light bulb and electricity, check these out:
