This unit seems like so much fun! I am glad that you are thinking about teaching Kindergarteners about living sustainable, this is very unique! One thing that you could do is write up and implement a lesson on composting! You could have families donate things that the students would be able to throw into the compost. This would also help families to get involved in your classroom too. By doing a compost, Â you could teach them about the science behind composting, which would get them understand that just because you're learning about one subject area, it doesn't mean that you can't incorporate other subject areas into that lesson. Another great thing about doing a lesson on composting is that students would be able to observe changes on a daily basis. They could do this in small group or as a whole group. They could draw out what they see in their notebooks and refer back to them as the days go by. Hope this helps!Â
Here's a video you could watch prior to the lesson to see what materials you need. You could also show your students this.
