Next week I'm starting a 6 week unit on plants with my grade three students. We must cover: the physical characteristics and life cycles of plants what plants need to survive how humans impact plant life I would like to present this as a critical thinking challenge to my students, and have decided that they (possibly in groups) have been "hired" as consultants to plan a garden that utilizes plants native to this area (we're in Vancouver). As part of this they will have to choose plants, find out what these plants would need to survive (soil etc.), which plants work together, and how such plants would be affected by being planted in an urban neighbourhood. I will also be conducting experiments to look at plants structures etc. to augment this information. We will have a space to actually do some gardening as well on the school property. I was hoping people would have suggestions for resources for my students and myself. The children must conduct their own research (with guidance and structure from me of course). We would also like to go on a fieldtrip and were wondering if anyone had any suggestions of a place children would love. UBC gardens are not an option as they don't give tours to children as young as mine. Thank you!
