In this activity, students will piece together a food web under the premise that they are explorers of an alien planet who observe the feeding habits of 15 organisms. The students create the food web, then answer a series of questions based on this food web. Alien Food Web is great for visual and tactile learners and can be used as the closing activity in a lesson on food webs and ecology. Depending on the grade level, the activity can be completed in one or two class periods. It comes with an answer key, too, so you don't have to go through the activity yourself.
