Life Systems, Habitats and Communities: how living things depend on one another and on the non-living parts of their habitat.
The Ontario Science and Technology, Grades 1–8 outcome for Grade 4 says: “Life Systems, Habitats and Communities: how living things depend on one another and on the non-living parts of their habitat.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson.
Our Living Planet Grade 4 · partly supports this outcome
Air, water, land and living things, and how each one depends on the others. Students build a sealed jar ecosystem to keep for a month and catch the water cycle in a bag on the window.
- Can a jar keep itself alive? 50–60 min to build, then 5 min check-ins twice a week for 4 weeks, and a 30 min Reveal and Act
Each team builds a small world of soil, water, air and plants inside a clear jar, seals it, and keeps an observation log for four weeks beside an open jar built the same way. Students explain how water and air are used again and again inside the sealed jar, and why it still needs light from outside.
