God is the Maker of all things but He didn't just make it and leave it, He cares for and provides for us and His creation. There is an icefish whose habitat is in the waters surrounding Antartica where temperatures in that water get down to 28 degrees Fahrenheit. This is cold enough to freeze the blood of most fish but not the icefish. God has provided a way for their bodies to produce a kind of antifreeze that allows their blood to flow. It is interesting to note that their blood has no red blood cells and therefore almost clear. How amazing our God is, that He can make anything to live anywhere on this world He created.
Regions of the World- The tundra
Where is the Tundra? My students have these Regions of the World maps in their student guidebooks that highlight on their map where these biomes are located.
Read Aloud- The polar Regions by cathryn sill
These books by Cathryn Sill are great for younger children. One whole side of a page is a picture of a habitat or region depicting either a type of flora or fauna or both. The words are not complicated and there are few of them so that there can be interaction and observation during the read aloud.
Here is a listening guide as well that catch the highlights of the book that my students fill out while I am reading.
Blubber Glove Investigation
One of the ways that animals survive the extreme cold weather of the tundra is by having a layer of blubber just under their skin to insulate them. This is a clever design by the Maker.
Insulation is a special way that God designed large marine and land animals to survive in extremely cold environments.
This is an opportunity to explore the insulating power of fat.
I added some shortening to a quart size ziplock bag and placed a smaller sandwich ziplock bag in it. I, then duct taped the bags together after I turned the tops inside out.
I lined up the students and had them all try each type of glove. I had just a normal quart size freezer bag, then a bag with newspaper, a bag with shortening, and a bag with foam.
I had the students label which bag made their hand feel the coldest on a scale of 1-4. We had some discussion about which bag they would want on their hands if they were in the Tundra. Most of them said the foam, however, I mentioned the practicality. The foam was really thick and if you had a glove like that, you wouldn't be able to do anything with your hands. I challenged them with science fair project to see what material they could use to make great gloves that were also useable.
I, then had the students try different materials like foam and newspaper to see if they would be good insulators.
Tundra biome sheet
The temperature range for the Tundra is -30 degrees Fahrenheit to 50 degrees Fahrenheit.
The average rainfall a year is less than 10 inches.
Grasses, mosses and twigs feed Lemmings and Arctic Hares which are hunted by Arctic Foxes and Snowy Owls. Caribou feed on grasses are hunted by wolves.
End Of Unit Treat
What a wonderful group of students that I had this semester! I gave each student a prize of a type of fauna from some of the biomes we studied this semester along with some candy inside a bag or plastic globe. I held up the vocabulary cards and would ask each student a question from the cards. Having the vocabulary sheet in front of them was like their multiple choice.
The World in His Hands Curriculum
These past 12 lessons have been from The World in His Hands Part 1. I sure hope that you will join us for Part 2 with another set of biomes, ecosystems, flora and fauna to discover.
