  1. Table salt is NaCl (sodium chloride). It is an ionic bond. This makes it dissolve very well in water, because H20 is polar. The positive sodium ions are attracted to the partially negative oxygens in the H20, while the negative chloride ions are attracted to the partially positive Hydrogens in H20.

     

    Table sugar is sucrose, which is made up of carbons and hydrogens. Since carbons and hydrogens are about equally electronegative, it is a nonpolar covalent bond, meaning the charge on the atoms within the molecule are negligible. Nonpolar solutes do not dissolve well in water, because water is polar. The water will exhibit hydrogen bonding, meaning the partial positive Hydrogens will be attracted to the partially negative Oxygens in the other water molecules. The sugar will be excluded.

     

    So if you want to make lemonade, you should heat the water when you dissolve the sugar in it. Otherwise, you'll just have lemon water with clumps of sugar at the bottom of the pitcher!

     

    This is probably a more detailed answer than you wanted, but I can't help it, I'm a chemistry minor!

  2. Yes, I know about Alice. My son will be launched with it this afternoon, most probably. I want him away from Scratch, so DD can learn at her own rhythm..

     

    And in the fall, I'm building a team of 2D game programmers. Next year, 3D game programming, and the following year, Wii programming. Do you think I'll get some interested kids ?

     

    PS. I was a game programmer before having kids. My skills are outdated now, but I should be able to lead a teen project.

     

    I want to join! I'm only 21, I could pretend to be a kid...

    (this from the college student who's nerdy enough to lurk on homeschooling forums in the hopes of someday being a homeschool mom...)

  3. :eek:

    Just in case you are interested, there are two laws that allows for things to be put in our food without them being listed.

    1. The 2% law. If there is less than 2% of an ingredient in an item they don't have to list it.

     

    2. Industry standard. If it is industry standard( the majority of the the products are made with this item) it does not have to be listed.(You would be surprised what is in that carton of milk you drink.

     

    We follow a diet that is stricter than glutton free called specific carb. diet and I don't use anything that is prepackaged or canned. You can get documentation from the company stating that they put nothing in the product that isn't listed if that is true but that doesn't keep you safe if they change their recipe.

    :eek:

  4. As a current undergrad student, I think breaks are totally necessary in a class that long :). In organic chemistry, on the occasions that my professor used the 4-hour lab slot for lectures, he would take a five or ten minute break every hour or so. He said it was to take advantage of the 50-minute lecture time that is "programmed" into us. However, people who are working instead of taking classes full time may have a different attention span.

     

    In that case, I would recommend what others are saying, a longer break halfway through.

     

    Also, like others were saying, mixing it up with discussion or other activities makes a huge difference. Anyone who's had a lab class knows how much worse it is trying to pay attention through a three or four hour lecture than a three or four hour lab.

     

    Just my $.2

  5. Covenant is one of his top choices at the moment - thanks for responding! I just finished reading Dr Fikkert/Steve Corbett's new book, When Helping Hurts - How to Alleviate Poverty Without Hurting the Poor and Yourself - quite an interesting read.

     

    I guess I can assume you like it there. :)

     

    I absolutely like it here! :D

  6. Covenant! I am a current student. My cousins are Comm Dev majors, the program is excellent.

     

    Do be advised that the product does not always match the advertising when it comes to Covenant: in reality, we are a liberal arts college with a Christian worldview. If you have any questions, email me at csinclair(at)covenant(dot)edu.

     

    Also, I believe the statistics say something like 20% of Covenant students were homeschooled. I think that is how many actually graduated from homeschool. Most of us (I'd guess 70 or 80%) were homeschooled at some point, myself (and my cousins) included!

     

    (Yes, I know it's a little strange for a college student to be reading homeschool forums, but I find it interesting!)

  7. I was homeschooled using BJU videos in tenth grade. My parents knew Spanish, but I did the subject myself using the videos. (BJU delivered stuff late, so I ended up doing Spanish I "block schedule" in one semester by doing two DVD lessons a day).

     

    At the end of that one semester, I as much Spanish as my ps-ed cousins did after Spanish I and II. (Of course, they did have an awful teacher...) The next year, I went to "real school" and found I was well prepared for Spanish II (which, incidentally, my aunt taught. It's always awkward having a relative as a teacher in a classroom setting, but having your aunt is not quite as bad as having your mom.)

  8. Being a dependent college student, these particular situations haven't yet applied to me; but FWIW I only tithe on my paycheck (allowance when I was younger; now I work part time in the college admissions office). I do think it's good to give a bit more (although I'm so disorganized that I usually wait months and then pay my tithe all at once.) The point is to give, not to be legalistic about it. The 10% stuff is OT, I believe we are not under that anymore. The NT just says to give cheerfully, although I still think 10% is the best starting place. I, however, despite being a missionary kid, am not an expert on such things. Do what you feel is right. Sorry if I'm rambling a bit.

  9. My mom made me study tihe SAT for 3 or four vacations! :eek: I did well on it though, so I can't really complain. I did the math stuff straight out of a prep book. I got really bored with the English stuff, though. :closedeyes: It's mostly vocab. Sometimes I would play word power at the reader's digest website instead.

  10. These books are amazing in any order, IMO. My older brother read them to me when I was in first grade (he was a really nice brother, plus we were both homeschooled at the time and had nothing better to do!). He read the Lion the Witch and the Wardrobe to me first, and went mostly in order (I think he might have switched the last two). I kind of like it because it makes the Magician's Nephew a fun explanation for why Professor Kirke doesn't think the kids are crazy. I agree with jail warden on that, and that The Magician's Nephew is not as good of a book (still good, but not as good).

  11. special approval from the College Board people.

     

    You can get out of a college class with either AP or CLEP. It's very helpful for registration, since college students with more credits get to register for classes earlier. I took the AP Bio exam and got 8 credits for that, and 4 credits from the AB Calc exam. What score you need and how many credits you get depends on the college.

  12. The AP is a series of standardized tests run by the same group as the SAT. You can take them at high schools and such. They are related to the CLEP tests, which are usually taken at colleges. You can't call a class AP on the transcript without special approval, but if you take the test and get a good score, a lot of colleges will accept that and give you credit for and/or let you place out of a class.
