Muscles and Sliding Filaments

 I don’t usually buy materials from TPT.  Yes I caved, broke down, and spent $4 on a model for sliding filaments.  Here and here are models we’ll use, too.  But, I didn’t find anything I really like.  The $4 purchase includes instructions, a slide deck, and a video link.  We’ll use the Amoeba Sisters’ video, too.  They have a worksheet to go along with their free video for $2.  What are we doing?  We’re building a model of ATP; our models use the Labaid kits.  I also bought an ATP/ ADP Energy Cycle, too.  We’re making clay, skeletal muscles, too.  Here’s hoping the models make a difference!
