Hello! My name is Mrs. McNulty.

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

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!

Mammals and Climate Change

Here are the links we looked at today to help guide our discussion about the two areas of focus for the expedition:
mammals & climate change.


Today many were surprised to learn about a mammal that lays eggs!

Memory check:

  • Do you remember what four attributes all mammals have in common?
  • What is the name of this special mammal who lays eggs?
  • What are some ways ecosystems can be changed?

Getting Ready for our Awesome Adventure!

There are about 21,000 species of fish on Earth, and about 800,000 different insects,
but only around 4,000 types of mammals!

Some of the mammals I may encounter or study on my expedition include:
porcupines, bats, snowshoe hares, white tail deer, lynx, moose, black bears, coyotes, foxes, martens, voles, skunks, raccoons, bobcats, mink, and something I had never heard of before called an ermine.

I am already learning some things and I haven't even gotten to the airport yet! =)

Yesterday, the 4th graders and I talked all about Nova Scotia and the expedition. We looked at where exactly it is on the map, made some predictions about the environment and climate, and also what type of adaptations the organisms living there may have.

Tomorrow, we will explore exactly what makes a mammal a mammal.
What are the attributes that all mammals have in common? Can you name all four?
