Weeks 3-5: Kaleidoscopes

3rd graders are are studying reflection. Is there a better way to master reflection than creating wonderful, whimsical kaleidoscopes? We watched a video on how kaleidoscopes are made and then each students made a list a materials they would need for their kaleidoscope. They also made a diagram to show how they are going to assemble their kaleidoscope.

Then they got to work assembling their kaleidoscopes. They did a great job understanding that the triangular prism of reflective paper was essential and they are learning why my repeated nagging about accurate measurements is important.

My classes are a very short 40 minutes. As such, I suspect we will need a couple more weeks to make our fabulous, finished kaleidoscopes. Ah well, 'tis time well spent.
