My Lent 2019 Book List Plans

Is this the year you really want to dive into Lent? Do you want to come out of this Lenten Season and truly feel that you've had a small share of living in the desert with Christ for 40 days? I know that I do. Maybe it's an upcoming birthday that's making me have more of a now-or-never type of attitude towards Lent. Or maybe I just acutely feel the necessity of truly modeling this for my children, and living it with my husband. Whatever it is, these are the books and resources I'm going to use this Lent to really LIVE the season from Ash Wednesday all the way through to Easter Vigil. Look them over. If something looks helpful to you, use it. If it inspires you, go with it. I hope all of these bless and encourage you.

Last week we studied the atmosphere in Chapter 3 of Apologia's Physical Science textbook. 

Physical Science by Apologia

This would have been a fairly easy set of experiments to perform if I was just doing this at home in my kitchen. I have a burner on my stove and ice in refrigerator and plenty of bowls!  It would have been super easy.

But in the co-op setting, it was trickier. First I had to bring in my burner from home. I also had to bring a cooler with ice, some metal bowls, balloons, pop cans, and plastic pop bottles. I was really bringing a full suitcase full of stuff to co-op!

In the first experiment, we were making a barometer of sorts. We were supposed to get all of the atmosphere out of the can and when the can gets plunged into icy cold water it was supposed to collapse. Here are a couple of tips- put the cans right on top of the burner. If you put it in a frying pan like they show in the book, you'll waste time getting the water in the cans to turn to steam. If I were at home I would, of course, put them in a pan, but in the classroom, the direct contact with the burner was faster. 


We tried three times and our cans never collapsed. They did fill up with water though so that shows we did get all of the air out of it and the pressure pushed the water into the empty can. To make it up to my class, I had some awesome videos on my Youtube channel of things imploding, like a steel drum and a tanker truck! They loved that. 

The second experiment required plastic bottles, balloons, ice and hot water. The bottle with a balloon tightly secured was  plunged into ice


 and then into super hot tap water. This had to be done in a kitchen because there was no way I was hauling super hot water down to my classroom! That experiment was successful!

The molecules of air were so excited, they started to inflate the balloon. 

To finish out the hour, I had a few extra videos to show the class. Some things about this chapter bugged me. They spent a lot of time on the ozone layer. The author, Jay Wile, really, REALLY wants the students not to buy into man-made climate change. I get it. But I think he sacrifices a lot of the available lesson space to that cause. It would have been much more interesting to talk about the perils of mountain climbing at super high altitudes, the old Concord air crafts and about things burning up on re-entry into the atmosphere. I'm on his side even! and I still find it annoying. Let's stick to science in the science book!!

Let me balance that by saying I LOVE how we can do all of these experiments without fancy expensive equipment AND I am loving the student workbooks for the course. I know you don't need them, but they sure make organizing the student's work a dream to check and easier for them to do their work as well.
