This is one of my favorite finds – thanks Cheryl! Great for rainy days or about any days. If you only find one out of the bunch that you can use then it’s worth your time – – but my bet is you’ll find a dozen or so that fit your teaching methods and ages.
Mostly elementary through middle school, but adults like many of these too.
Each one has a short VIDEO and full instructions with color photos for building and use. From the nice folks at the Watsonville Environmental Science”Workshop.
