Quick summary: During this lesson students explore dichotomous keys as a means for identifying and classifying living things. They begin by observing living things in the school yard. Following an introduction to dichotomous keys, students will create a key for living things found in the school yard. Finally, students will use the CSIRO Key to Invertebrates to identify invertebrates in the school yard and then create a poster/booklet about school mini-beasts.
This lesson is designed to be taught outside. It contains all the tools required for students to reap the benefits of being outdoors while learning the outcomes of the Australian Curriculum. By spending time outdoors and connecting to nature, students are more likely to care for and conserve nature as adults.
- Students recognise different types of dichotomous keys and understand how we use these keys to identify organisms.
- Students understand how to use and create a dichotomous key.
- Students recognise how mini-beasts are an important part of our environment and identify actions we can take to conserve mini-beast habitats.
- Students recognise the mental, physical and academic benefits of completing classroom activities outside.
