Hands-on activity demonstrating the digestive tract of ruminant animals. Allows students to really "see" what the digestive tract is without having the actual tract available. Also allows students to extrapolate information. The student hand-out that goes along with this is titled "Digestion Activity Student Copy."

I attempted it with a paper coffee filter with holes cut into it & I cut the Skittles in half. My suggestion is to do a dry run yourself before you do it with your students. I made this for my student teaching & didn't do a dry run. My kids still had LOTS of fun & still got the big concept, but the coffee filter step was the one step where we got caught up because the holes weren't big enough for the Skittles to fit through. If you know of a better candy/filter for it, go right ahead!
This sounds like a ton of fun! When you say "coffee filter", do you mean the paper kind? or the ones made of metal that act as a strainer? I'm asking because in Step 4e, I don't understand how the pasta will go through the coffee filter but the skittles won't. Are the students supposed to sort them out? Thanks! I'm hoping to do this activity very soon.
