Stoichiometry In LoF


Recommended Posts

I thought that part was hysterical, and difficult.

 

Move on.

 

If it makes you feel better, I didn't think my kids understood it, really, and then we came across a question in a bridge that made you balance iron + oxygen = rust. It was not a complicated equation at all. However, I wrote it on the board and they did it, correctly in no time at all. I was stunned.

 

So, I personally, don't think it is a big deal, whether or not they get that yet... as it is not math. It is just a place for the author to do what he does best... introduce an advanced topic in an odd way so that when they DO experience it "for real", they already have an exposure to it that was fun.

 

Besides, he does throw in easier questions throughout the rest of the text, I am sure that your kid will be better at it by the end of the book. But if not... don't worry about it! :D

IS that in the Biology pre-Alg1 book?

 

Yes. He has the kids balancing chemical equations, which is not as logical or easy as algebraic equations, in one chapter. It is really nuts. ;) The thing is that after that chapter my kids did get a little better at "normal" equations. It was like... "Hey look at this crazy thing! At least you aren't doing THIS! Algebra is no sweat compared to this!". I thought it was brilliant.

 

And it is very hard to pronounce. :D

Ds did it over the summer. He struggled with this part, but got good enough at it to pass the bridge.

 

Now, in 8th grade we're doing Physical Science. He has had to do a LOT more than what Fred ever did. He thinks its a breeze. Fred is great prep for a tough Physical Science course.

Well my thoughts were to skip it now, then revisit after she is done with pre-algebra. She will be doing Physical Science next year with Apologia so maybe that will work!

It took my daughter five hours or so to figure it out. I gave her all the time and encouragement she needed to solve the problem. Her father worked out the problem himself (without showing her how, or the answer) just to show her it could be done. Once she figured it out it was an amazing light bulb moment for her! She was so proud of herself. She now wants to be a chemist when she grows up :hurray: That is pretty amazing since she used to dissolve into tears every time I got out a math or science book!

I'm not even sure if Apologia Physical Science does it. It is much lighter on math than what we are doing because it is designed as an eighth grade course (the one we are doing is 9th grade level).

 

I don't see anything wrong with your plan. I think ds got it much more when he understood the science with it better instead of having it thrown at him out of the blue in Fred. I still think having encountered it before was good for him though.

DD just does.not.get.it. :glare: Can I give up? Will it hurt her not to learn this in 7th grade???

 

Sure, she can give up. I feel that it was to help a child better see Algebra in the balance of the equations. I see it as just like in Algebra the equations must balance. In Stoichiometry, the formulae must balance.

 

If you skip it, it won't harm her. However, in the bridge, if she passes the first one, she won't have to deal with it. If she has to do a second try, it is in there.

 

Blessings,

Karen
