# Day 3: CVPM packet

Lots to write about here, but I’m going to try to keep it short by promising to write later about the cart launch lab. I was inspired by my colleague Ben who put together an amazing packet for the regular physics classes at our school. I was planning, for my college level class, to jump right into problem solving in constant velocity. After looking at what Ben had done and cross referencing with Kelly, I decided I needed more conceptual materials before problem solving. Thus I put together a packet that draws largely from Kelly and the standard modeling materials. The main difference, however, is that class I teach, since it is articulated through the University of Minnesota, emphasizes algebraic problem solving more so than modeling instruction. Thus I wrote a new worksheet, practice 3 in the packet, to deploy the model. It emphasizes solving the problem algebraically but using graphical methods to guide and check the answer. Let me know what you think, here’s a view only copy of the packet.

1. What’s the setup for the Cart Launch lab?

I think the packet looks great! One of these days I’ll throw together awesome packets like this. For now I just mostly build off other awesome people’s work. 🙂

• I’m going to blog about it, but it’s basically doing the same lab but with launching dynamics carts and using video analysis instead. I like that it both introduces video and starts the process of breaking the model since the carts slow down a bit.

• And by launching I mean I have them launch using their spring plunger, but start tracking after that as they coast along a level track.

I’m ditching the ranking task in this packet this year. It’s trivial for them, so I don’t think it’s worth the time. (Later ranking tasks are not trivial, but this CVPM one seems to be each year.) Just FYI.

I’ve ‘borrowed’ from Kelly alot and it looks good. I think my kids could use the structure that the Practice 3 involves, so I’d love to ‘borrow’ from you as well.
