I am looking at getting my hands on the Force as Interactions Unit posted on the physical science curriculum website. The site refers me to Pat Burr who wrote the material and says we must contact Pat for the materials. I have attempted a few times with no response. Anyone else run into this issue?
I tried to contact Pat several weeks ago, too, and never got a response. Perhaps the email address is no longer one being checked.
I would imagine that the Unit 4 Physical Science materials are a modified version of the Free-Particle Model (Unit 4) of the Physics Mechanics materials and/or a modified version of some of the Chemistry units. You might look there for a start until someone can sort the email issue out and get Pat in touch with you.
While attending a recent chem workshop in New Orleans, I ran across Dennis Glass who was co-leading a phys sci workshop. He had his own materials for unit 4. I’m in the process of getting his contact info – when I do, I will share.
