When you work with school children, teaching about immunity and illness prevention is a priority! This approach includes a discussion, kid-friendly online articles, a creative writing assignment, and a quiz on the role of leukocytes and the immune system. Though the teacher's guide was published in 2006, the home website has been updated since that time. A video, quiz, and other activities have been added, but the titles on this document may not exactly match the titles on the website. You might want to bookmark the links prior to sending learners to the computer lab in order to maximize time.
