I've been learning so much from reading #NGSSblogs and from the Edutopia article from Eric Brunsell ( @Brunsell ), so again I want to give a big shoutout to these rock stars!!!! I'm trying to teach myself how to do this Claims, Evidence and Reasoning in an NGSS sort of way.

It seemed to me that if the PE was all about kinetic energy from MS PS3-1, that I should have some graphical data to display. I would use the Cross-cutting Concept (also known as CCC) of Proportions to help guide students in making a claim and making their analysis of the evidence. What a slick way to think about how to weave a mathematical idea into the science conversation.

I first tried to use Desmos to create my graphs. It was too much for me. Now I know I should have been able to figure it out but I fiddled and fiddled....finally was so frustrated I just pulled out a piece of graph paper and did it the old fashion way with a pencil and my brain doing computations. That really helped me and I realized that I should just use something like Create A Graph since I already had the table data all figured out.

Worked slicker than a whistle.

Now I'll go back and separate this into two separate graphs so the teaching will be easier. But I'm going to do the CER with the graph as suggest by Brunsell's article. Then I'm going to make sorting cards with the Create a Graph and also create corresponding table data.

I have to say this task had me going. It makes me wish I had a collaborative partner....I'm the only one teaching my course in the building so I'm a singleton. There would be so much less work if there was someone to throw ideas around....but I also like the fact that I struggled along until I figured it out.

If you're still reading and you want to be a Critical Friend, tell me what you think about this approach.
