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."
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.
