Hello! My name is Mrs. McNulty.

Please travel with me to Nova Scotia to study climate change and mammals!

Tuesday, March 30, 2010


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!


  1. Mammals are warm blooded,have hair/fur,live birth,and mammal babies drink milk.The mammal that lays eggs is the Platapus,and ecosystems can be changed by
    humans or nature. Good luck on your trip to Nova Scotia,Mrs.McNulty,and have fun!!!

  2. Mrs.mcnulty,HAVE FUN!!!!!!!!!!!
    My footprint calclator says that we would need 3.9 planets if everybody lived like me!!!! Wozers!!!! I need to take care of the earth more(there is only 1 earth , and billions of us)!!!!!!!!!!!!!!!

  3. Hey Mrs.Mcnulty!!! I miss you so much.Some of the questions I didnt know so I just guessed on those.Mine said if there were more people like me they would need 4.8 planet earths.They also said "To support my lifestyle it takes 21.2 global acres of the Earth's productive area."(21.5 tons of carbon dioxide)

    Guess who!
