Casting the pyramid

Good news - the lesson plan went pretty well! I'm proud of how we did, considering how stressed I was about it. Unfortunately, I haven't been able to get the plaster for the pyramid yet, but I'm planning on doing it today. I'll just stop by Home Depot, and get some plaster, concrete and little foam peanuts so the finished concrete pyramid won't weigh too much. I've already taken home the tank and have made sure that the pyramid fits. When I'm done making it, I will be sure to put up pictures.
