Today we talked more about how we humans effect ecosystems. We learned that the mark we make on the planet (the resources we use) is sometimes called our "footprint". We read a great book called Human Footprint by Ellen Kirk that really helped us see the heavy impact we have on the planet.
We also looked at a really cool interactive website which can show us what our individual impact is. Check out the "Footprint Calculator": http://www.footprintnetwork.org/en/index.php/GFN/page/calculators/
Finally, we took some time to look at animal footprints in a wonderful book called Who Made These Tracks? There are a lot of animals in this book that are native to Nova Scotia! We talked about which ones I might see and how I will have to get to know their footprints, or tracks, very well!
Less than two weeks now, and I'm off! I think the fourth grade science students at Thomas Edison and I are well prepared for the expedition, but I know there will also be so much more to learn. I can't wait!
Tell me about your Footprint Calculator results!
