We discussed gravity in our February class. Here is a great video from Minute Physics. He explains complex physics, well, in just a few minutes!
Hi all thanks for participating in PEMDAS 2013 fundraising. We sold 9 worm boxes!
The worm boses do need moisture. Be sure to add some water at least once a week to keep them happy. If the grass gets very moldy, you can empty out the box and fill in with regular dirt if you like. Or ad fressh grass and leaves if you want.
Thank you Lindsay for teaching in October with states of matter!
Discussing solids, liquids, and gases. With a repeate guess of carbon dioxide with dry ice again!
