The science behind saving money.

Over the last couple years I have really been a tightwad when it comes to heating my house.  I have wood and coal burning stoves but I know that those don't help as much as they should.  They pull cool air in from the outside because they have to have a constant supply of oxygen in order to work properly.  This has me wondering if I can vent them straight to the outside so that the air supply doesn't have to come from inside the house.  I wonder what the cost and savings will be.  I'd love to save a few bucks every month in order to buy more hunting equipment.  Anyone have any better ideas than just using metal ductwork and running it from outside to the air intake on the stove?

The Incredible Egg

The egg. 

The total package.  Tasty breakfast, genesis of cute fuzzy chicks, and the ultimate teaching tool. 

I've recently come to realize that an egg is the ultimate science teaching tool.  What other object can be used to teach osmosis, embryonic development, scientific measurement, chemical reactions, and the scientific method.  I have used eggs to teach osmosis and chemical reactions and osmosis every year that I have been teaching school.  What I didn't realize about the egg is that it is a great tool for teaching many other science practices. The last two years, my classes have hatched chickens and ducks near the end of the school year.  The quest for a high percentage hatch has led my students to use the scientific method without knowing they were using it. We have tried changing the humidity level on each new hatch and have found that it matters greatly to the hatch rate.  We have also experimented with assisting chicks with hatching.  I had done this before and knew the risks of helping too early and not helping early enough.  The greatest life lesson is life itself.  On top of all of this, it does the most important thing in teaching.  It gets students interested.

I don't understand why, but I've tried to save the above link as a link  but it won't work that way.  You can copy and paste it into the address bar on a new page and it goes to the right place. 


Now its working. 

Well, I'm back at it again. I hope I can learn how to use this thing.

Biology class 2016/2017

I'm going to try something new for my biology and integrated science classes this year.  I plan to video short lessons and put them on my teacher website.  I will have riddles or questions hidden in the video that students can answer for a chance to win some kind of prize.  I think this will get students to use the website and may help them learn a little more.
