My Sci > Teacher ideas > Unit plan > Earthworms (lower primary) Part 1: Learning outcomes plan Main idea: Earthworms are living animals adapted for life in the soil. Science strand: Level: 1-2 Living World: Life processes Recognise that all living things have certain requirements so they can Year: 2-4 stay alive. Recognise that living things are suited to their particular habitat. Teacher: Angela Schipper Recognise that living things can be grouped in different ways. Overarching learning outcomes: In building understandings about earthworms, students will integrate: understanding what makes an earthworm a living animal (scientific knowledge) an investigation into the characteristics of living things and characteristics of an animal (scientific practice) extending their experiences and personal explanations of the natural world (nature of science). Conceptual learning outcomes Procedural learning outcomes Nature of science outcomes Technical learning outcomes Students will understand that: Students will be able to: Students will understand and Students will be able to: scientists group or classify living identify some of the appreciate that: use interactives from the Science things characteristics of living things, scientists group or classify Learning Hub to explore and earthworms are living, and all with reference to earthworms organisms to identify them and discuss the characteristics of living things share certain life identify some of the to see what species they are living things and the processes characteristics of animals, with most closely related to characteristics of animals earthworms are animals, and reference to earthworms scientists have specialist use hand lenses, cameras or animals share four key observe earthworms (either living vocabulary to help them other devices to observe characteristics specimens or in video clips) and communicate effectively. earthworm movement and earthworms have common identify and discuss differences physical characteristics. characteristics and adaptations between the species. that suit their life in the soil ecosystem earthworms’ characteristics vary depending on where they live in the soil ecosystem.

All rights reserved. www.sciencelearn.org.nz Key student outcomes Students will begin to recognise that things share common characteristics and we can group them according to these characteristics. Students begin to describe the characteristics of living things. Students begin to classify things as living or non-living based on these characteristics. Students use their knowledge of the characteristics of living things to challenge their classmates’ understanding of these characteristics. 2 My Sci > Teacher ideas > Unit plan > Earthworms (lower primary) Main idea: Earthworms are animals and share common characteristics with other animals.

Students begin to describe the characteristics of animals. Students begin to classify things as animal or not. 3 My Sci > Teacher ideas > Unit plan > Earthworms (lower primary) Main idea: Earthworms are living animals.

Key student outcomes Review the characteristics of living things and animals. Watch the video clip, asking students to watch and listen for evidence that earthworms are alive and are animals. Students use their knowledge of animal characteristics to identify that earthworms are animals. The video shows movement, sensitivity, growth and reproduction. Introduce this section by discussing special vocabulary associated with a sport or art. Explain that scientists also use special vocabulary to help them communicate accurately. Read through the interactive with the students. The language is sophisticated so take time to discuss the various body parts and how they tie into the characteristics of living things. With younger students, concentrate on the outside of the earthworm’s body. Earthworms > Observing Prior to working with students, Earthworms read through the activity and (www.sciencelearn.org.nz/Science- determine which portion of the Stories/Earthworms/Observingactivity is appropriate for your earthworms) students.

All rights reserved. www.sciencelearn.org.nz Planned interactions Students learn that scientists have special vocabulary. Students begin to use some of this vocabulary. Students begin to identify some of the physical characteristics of earthworms and see how these help to determine that earthworms are both alive and animals. Students begin to use accurate vocabulary associated with earthworms. Students observe and identify some of the characteristics that demonstrate that earthworms are alive and are animals. 4 My Sci > Teacher ideas > Unit plan > Earthworms (lower primary) Shallow tray of water Plastic tongs (optional) Hand lenses or other observational or recording devices Note: If earthworms are not available, use all three video clips to observe movement and anatomy. © Copyright 2012.

Students will have a simple understanding of the different roles earthworms have within the soil ecosystem. Students will gain a deeper understanding of earthworms’ similarities and differences and their roles within the soil ecosystem. Students begin to use scientific vocabulary in their writing. Students view images and text to find similarities and differences between earthworm species. Students record these similarities and differences in a creative manner. 6 My Sci > Teacher ideas > Unit plan > Earthworms (lower primary) Exercise books Access to computers 4.4 Wormface – Earthworms > Wormface – social social networking networking for earthworms for earthworms.

Older students could be encouraged to keep their poems scientific or to include scientific vocabulary where possible. Wormface is designed to replicate the creation of an online social networking profile. Decide whether this is appropriate for your students. Complete a Wormface profile as a class so students understand the process and the vocabulary. Encourage students to use their research skills to develop their own profile. Students work individually or in groups to develop their own profile. In doing so, they demonstrate their level of understanding about the physical characteristics and the role their chosen earthworms plays in the soil ecosystem. 7 My Sci > Teacher ideas > Unit plan > Earthworms (lower primary) Main idea: Ethical considerations of keeping earthworms (and all living things) in the classroom.
