Eggs have to be extra strong so momma goose can keep them warm
Iam SOOO egg-cited — the Easter Bunny had better be hopping by my house this year (despite the large snow drifts)! When the Easter Bunny comes, I hope he will not disturb all the Canadian Geese that have nests in my backyard.
I truly enjoy seeing the couples come back year after year. It is especially wonderful to see all those little babies following them around!
Hmm, this makes me wonder how do these eggs not crush under the weight of the geese? These are not small birds. Well, I do not want to disturb the momma goose, so we had better investigate this ourselves. Let’s get started!
*Remember to ask an adult before doing this experiment.
Materials
• Six eggs
• Scissors
• Masking tape
• Cup
• Sink
• Soap and water
• Four or five heavy books
• Counter top to work on
Procedure
1. Crack each eggs VERY carefully into a cup. Set aside for another use.
2. GENTLY wash the eggshells with warm soapy water. Allow them to dry.
3. Using the scissors, cut the eggshells evenly all the way around.
4. Place a piece of tape on the cup edge of EACH eggshell.
5. Line the eggshells CUT side down on the countertop.
6. Place one heavy book at a time on top of the eggs. 7. Observe.
What is going on?
As mentioned, I had to do this experiment in order to learn just how those eggs do not break and hatch under the large momma goose in my backyard. In this experiment, we were able to see that the eggs easily held up to several LARGE heavy books, which would be similar to a momma goose sitting on her eggs.
The eggs do not break due to their unique shape. The arc like shape of the egg helps support the weight of the momma sitting on them and resulting in those cute little goslings running around in just a matter of weeks!
I hope all of the students have a great spring break! See you when you return.

Before I get into paper money I would remind you about the Medicine Hat Coin & Stamp Show on April 6, below the grandstand at the Stampede grounds from 10 a.m. to 4 p.m.
There will be dealers happy to appraise your bills, tokens or coins. Maybe you are missing a few in your collection or have some to sell. Stamp collectors there will have all varieties for sale from all countries, or you may want to sell a few you have. This is the place to go. This is the largest coin and stamp show in southern Alberta with reputable and knowledgeable people.
Now let us talk about paper money. I am sure every house has a few old paper bills tucked away, whether it is the old $1, $2, or maybe even the centennial dollar. When new issues of paper come out — unlike coins — the bank automatically takes back all the old ones, and eventually most are taken out of circulation.
You would be surprised how many teens or people in their early 20s who have come to our shows have never seen a $1 or $2 bill. Bills are valued on three things: condition, signatures and serial numbers.
Bills in any year may come anywhere between six and 50 varieties in that denomination. This, of course, varies the price for that note, anywhere from face value to hundreds of dollars.
