Science . . . Again

As I continue in our science studies this year, I can’t help but think about next year. I already know I’m not going to continue to use God’s Design, even with the new (full color) design because the Physics level texts are too high level for my youngsters. (The Chemistry ones are too high level, IMO, and that was a mistake.) I was leaning toward Science in a Nutshell kits or TOPS. Then, I thought maybe I might just go ahead and break the bank with NOEO.

I revisited my curriculum post from almost a year ago. It reminded me of Pandia Press. I’m relooking at their Chemistry curriculum and wondering if it is too late to start over with their course. ;-) (I’m only slightly joking.) I’m not ready to switch (yet), but I saw a sample page on their website about explaining states of matter and it seems to do a better job of speaking to my kid’s level. (It is designed for Grades 2+. God’s Design for Chemistry is designed for Grades 3+.)

But while I was there, I checked out the blog of Pandia’s owner. This blog piece caught my eye. It is a brief review of a speech given at a homeschool convention.

Many homeschool moms and I have discussed this topic. One of the homeschooling Yahoo groups I am on is currently discussing the problem of selecting a “good” science curriculum, especially for the high school level. I agree, in principle, with what she is saying. (I don’t agree with everything she says in the blog piece. I do agree with the basic premise.) It is hard to find a science (or history) curriculum that doesn’t have an “agenda.” I, too, would rather the agenda be front & center so I can either steer clear of it, embrace it (if that is what I wish), or Sharpie it out. :-)

Three States of (what) Matter

At the beginning of a recent science class, I was reviewing what we have learned recently. I started with, “The three most common states of matter on the earth are . . . ” I paused, waiting for the kids to chime in.

My #2 child piped up, “Solid, liquid, and gratitude!”

Science Quiz

After much deliberation, I choose to purchase Answers In Genesis’s God’s Design for Chemistry series for our science this year. As it is designed for Grades 3-8, it is a bit of a stretch for our young family. I figured my (young-for-her-grade) 3rd grader would grasp most of it and my first grader would be along for the ride. They both love experiments and the texts (Properties of Matter & Properties of Atoms & Molecules) have a fun activity or experiment almost every single lesson.

Both have really struggled grasping the concepts. I didn’t realize how much trouble they would have. The first quiz (Lessons 1-4 in Properties of Matter book) didn’t go the greatest. But the second was really dismal. The older child grasp the concepts as shown in the short answer portion of the quiz but doesn’t have a clue on the terminology. The younger child can figure out the terminology as shown by her fairly decent score in the matching portion of the quiz but doesn’t get the underlying concept.

But that’s not why I’m posting about this. I just wanted to share Child #2’s answer on one of the “short answer” questions because it had me rolling with laughter. I must set this up by saying that 1) we studied astronomy last year and 2) the chemistry text discussed the concept of buoyancy with examples of swimming in a pool filled with rubbing alcohol (where we would likely have issues staying afloat) and a pool filled with mercury (which would be a bad idea, obviously, but where we would easily stay afloat) due to the different material densities.

Quiz question: “If an object floats in one liquid but sinks in another, what does that tell you about the densities of the two liquids?”

Child #2 answer, “The one that sinks is probably rubbing alcohol and the other is probably Saturn or Uranus or something you can float on.”

[Obviously, she was trying to think of the word "mercury" and substituted names of two other planets instead.] Is this funny to anyone else or is it one of those “you had to be there” moments?

H1N1 or the regular flu?

I was listening to the top doctor in the state I live in talk on the radio the other day about the H1N1 flu. She promotes vaccines and is highly respected. I can’t remember her title, but she’s the a medical doctor with a title tied to the state somehow.

Anyway, the guys on the radio were asking her questions and letting her promote the H1N1 vaccine. I wish I could link you to an audio of her interview, but the radio station doesn’t have a podcast up of it. I’ll paraphrase what she said, but I realize that audio of it would be better proof than me typing my remembrance of what she said.

She repeated the mantra that certain target populations should receive the vaccine. She said that even if you thought you had H1N1 already, you should STILL get the vaccine. When questioned on this, she said that you could have had the regular flu or a respiratory infection instead, so you should still get the vaccine.

About five minutes later, when asked about how it has been reported that doctors are being told to report all flu cases as H1N1 – even without testing to determine which one they are, she said it was very simple and easy to tell the difference between H1N1 and the regular flu because of the severity of the illness. (She said something like, “Ask someone who has had H1N1 and they will tell you it is completely different from the regular flu.”) When one of the radio guys asked about a respiratory infection (which she had just used as an example of something that could have been mistaken for H1N1), the doctor said that of course the symptoms were very different.

I thought to myself, “Mrs. Dr. Lady, you can’t have it both ways!”

She said that 90+% of the cases of the flu that they are seeing are H1N1. When asked how she knows this if they are assuming all cases are H1N1, she replied that it isn’t regular flu season yet.

I wish I had the audio to post. It was incredible! And the radio guys on with her just let her get away with it. (The next hour, the next guy on seemed to have caught some of the inconsistencies, but he didn’t dwell on them.) Absolutely amazing.

We are not getting the immunizations. I’m trying to keep us from getting the H1N1 while we have a newborn in the house. At some point, if the house is exposed to it, at least we will have the immunity to this strain of it after we recover. I would just rather we not get it while the baby is so little and vulnerable. So, we wash-wash-wash and we stay away from those who have been sick as much as possible (+ a week that they say you can still be contagious). But our town has been overrun with the flu (H1N1 or regular, I don’t know!).
