These task cards are a little different than my usual format. I have information above every two task cards that the students must read to get the answer. I also have a station that has 8 boxes that fit one inside the other. Students must relate this to the Levels of Classification including Domain Kingdom Phylum Class Order Family Genus Species. I ordered my boxes from the Container Store Online. However, there is a picture of the different colored boxes, so if you don't want to order the boxes, you can just use the picture.
