Quick summary: In this activity students explore the idea of food webs by undertaking a nature survey and identifying the role each organism plays in their schoolyard food web. Students are asked to record both indigenous and introduced species and how their presence affects the health and balance of the schoolyard food web. Parts of this lesson can be completed using a SMARTboard activity.
Following this lesson is an ideal way for students to participate in Planet Ark’s Schools Tree Day – the largest nature-care event in Australian schools. You and your students will join thousands of amazing teachers in making a difference, fostering a child’s love of nature and creating positive environmental change. So, get growing! It only takes a minute to register for Schools Tree Day.
