Maryland pays half the cost of DE. But Maryland is expensive and colleges here are costly.

Melissa - We're sorry you're seeing errors in the Chemistry Flexbook. We update our content with all errors reported on a daily basis. Please make sure you go back to ck12.org and download the book from there to make sure you have the latest, most updated version.
If you have any questions, you can always reach us at support@ck12.org.
Happy teaching,
Your CK-12 Team
Unfortunately, I never received that feedback and after I downloaded the answer key, I was locked out of the answer key. If the answer key was updated, I can not see the new version.

As an engineer, married to someone who taught sophmore electrical engineering courses, DO NOT let him skip Calculus I for Engineers in college. AP calculus is NOT strong enough to replace the college course. My dh had sophmore students who could not keep up with the math because they went straight to Cal II from high school. If your son is ready for Calculus his senior year, sign him up for dual enrollment at the community college for Calculus for Engineers. (Yes, engineers do have their own Calculus sequence.)
Chemistry should NOT be attempted until the student has a strong understanding of Algebra I. I am good friends with the local Co Op science teacher and she has learned that she must pretest her students for Alg I mastery. Make sure he learns dimensional analysis and puts proper units on every problem.

Having too much material is not considered a problem. A lesson plan is needed for most textbooks.
Maybe CK12 would work better if it had some volunteer editors (such as yourself) that could suggest changes.
I did submit many errors to their clunky online reporting; however, I never knew if anyone read them. Towards the end of the book, I just gave up spending 5 minutes at a time reporting the problem and concentrated on making my own answer key.

Review of CK12 Chemistry:
Background: I have a bachlors in Chemical Engineering and worked as a lab rat in college.
As of the current edition, I can not recommend this text. I am working though the last chapter and I have been frustrated with many errors in the text and answer key. Basic calculations are just wrong and balanced chemical equations are incorrect. It could easily lead to hair pulling out if you were not strong in chemistry trying to figure out where you went wrong when the text is wrong.
Since this is a second edition, some material was moved from chapter to chapter but the questions and test were not updated so material in Chapter 14 test was not presented until Chapter 15. I had to pretake the test to make sure the questions were appropriate and cut and add questions.
Several of the linked materials were broken or difficult to get to. The formatting was not printer friendly.
I have a friend who teaches Chemistry from Apologia in a co op so I was able to compare notes with her. CK 12 covers a number of topics not covered in Apologia. This can be a disadvantage since covering the whole books can get overwhelming. My friend deemed several topic too advanced for a high school text. (She taught high school chemistry before having kids.)
If a revised edition and a lesson plan was released, I would consider this book again. Unless you have a very strong background in chemistry, this is not the text for you.

My dh is set to The March for Darth Vader. When he gets home from work, he will walk up the stairs humming this song so I put it on my phone.

My DD14 had a small mouth and crowded teeth. I agree with much of what has already been said.
Go with your gut. I paid more to go with the Ortho who had a better organized office and came highly recommended for someone who had a lot of problems.
We did a two stage. First, she had a removable expander. She could take it out to brush her teeth and to adjust it. Her lower jaw naturally expanded as the upper jaw.
When you head out to the ortho office for adjustment, take some tylenol to ease the discomfort.
The most discomfort will occur when they pull down teeth that are so slow to erupt.
Ask about their policy of wisdon teeth. It is not standard to automatically pull the wisdom teeth.
Consider your finances. My ortho offered a discount if you paid cash. I did not know this at first but I was able to use my health savings plan to pay off my balance. The HSA money lowers my tax burden.
My dd will have to wear invisiline for years after she gets her braces.

When I am making fried rice for lunch, I saute onions and any raw veggies in the refrigerator. Once they are cooked, I add anything that was precooked, such as leftover veggies or meat. I dump in the left over rice, make a whole in the center of the rice, pour in oil (high smoke point) and crack an egg. I left the egg cook for 20-30 seconds. I stir it all up and add 1 part soy sauce, 1 part fish sauce. Stir, cut the heat, cover and let sit for a minute to finish cooking the egg.
When I fix it for dinner, I add cabbage to the mixture before the egg. I buy the pre cut cabbage for making cole slaw.
The fish sauce makes all the difference.

I live about 1-1/2 hours from DC. I like to park at the Huntington Station and ride in since driving in DC is crazy. We have done multiple day trips.
I love the Natural History Museum. The dinosaur exhibit is about to be closed down for renovation which will take about 5 years. The other parts of the museum are great.
Ranking for day trips:
Natural History
American History
Space
Archieves
Newseum ( lot of walking)
Capitol
In the afternoons, when the tourist are tired, you can flag down a bicycle tram to whisk you back to the metro. Then I hope in my car and jump back on 495 for home without any delays.
I often use my gps on my phone to find a place to take a lunch break or a starbucks. My kids always vote for lunch at PotBelly's. We like the one near the Archieve Metro stop.

It has been a long time since I looked at water chemistry so here goes nothing.
Both tap and distilled water will absorb CO2 from the air to form carbonic acid. Tap water will have other things, such as iron, flouride, sulfide (I lived in Tampa for several years and the sulfide were horrible) and calcium. All these things can be buffers.
How long have you run your tank? Is it in equilibrium? Do you have a healthy plant life? Do you have enough oxygen? Is your filter bed built up? (A green slimy filter bed is good.) It your tank in sunlight? (sunlight bad). I would consider letting the tank mature some before adding any more fish. Please let us know how this turns out, I am curious. :thumbup:
-
I did some dissection last year. It was very helpful to watch a dissection on Youtube first so we would know what we were looking for and how to cut open the specimen correctly.

We just did buffers. A buffer prevents changes in pH in a system.
The Henderson Hasselbach Equaiton is
-log [H+] = pH
Thus pH = - log Ka + log{[salt]/[acid]}
where Ka is the dissocation constant
[salt] = molarity of salt in Moles/Liter
[acid] = molarity of acid in Moles/Liter
The salt and acid must be related as acid and conjugate salt such as HC2H3O2 and NaC2H3O2 (vinegar and sodium acetate) or HCl and NaCl (hydrocholric acid and sodium chloride)
The kicker of this is tap water has hardness to it so it contains H2CO3/HCO3- which is a buffer. Leaving water on the counter picks up CO2 for the air and shifts the buffer solution.
If I remember from my fish tanks day a decade ago, having good algae in the tank helped with keeping the pH steady. Adding small amounts of water frequently is better than adding a large amount at longer intervals. Also, a good filter bed is vital for the tank. You can jump start a tank by brings the good stuff home (water sample) home from the fish store.

I earned a Chemical Engineering degree and some of my classmates went to work in the Petroleum Industry. They worked mainly at the refineries. If he wants to do field work, he should make sure the program covers that area as my program did not.
Also, my dh taught Electrical Engineering for 5 years. I would strongly recommend NOT skipping the Calc I for engineers or Physics I for engineers. The AP class in both of these field are not rigorous enough for future classes. My dh noticed the students that had the most problems in his class skipped Calc I or Physics I at the university and went straight to Calc II or Physics II.
My hardest class was Organic but I was in a class of over 100 students, many that were Pre Med majors. It was the weed out course for the Pre Meds so they made it harder that I really needed. After all, I did not need to memories every step of the bromide reaction as an engineer, I just need to know that it existed and be able to look it up if I ever needed it. Even my department chairman said he got a D in Organic.

I keep seeing where the craft climbed to 45,000 feet. The ceiling for this aircrast, Boeing 777-200ER, is 41,300ft. This meaning that the plane can not fly above this because the air is too thin to give it the required lift. It is impossible for this plane to fly to 45,000 feet.
Then it dived to 25,000 feet. That is a 20,000 ft difference. I am not sure of the time difference but one of the talking head said that it would be impossible to drop 20,000 ft that quickly with this airplane. (It is not a fighter jet.) He said it was a data glitch.
The quality of the facts coming out about this case is poor so I do not believe it climbed and dove so quickly. JMHO.
-
What does that term mean? Does it mean the airplane may be on the deck of some aircraft carrier? Just curious.
A 777 is too large to land on an aircraft carrier. DH works in this field and he said, "No way it could land on an aircraft carrier". I think the term means it is on land somewher.

Trader Joe's Chocolate Chips are dairy free. It is a 90 minute drive to TJ for me so I buy 24 bags at a time. They always ask me if I am planning on a lot of baking.
I also use Earth Balance.

Interior angels of a pentagon = (n-2) x 180 = 3 x 180 = 540
Each interior angel of pentagon = 540 / 5 = 108
Now to the pentagram, which extends the lines of a pentagon to form a star.
Look at the triangle formed by extenting the lines. It is an isoceles triangle. The base angels are compliments of the interior angels of the pentagon (108) thus
Angel at base of triangle = 180 - 108 = 72
Both base angels are equal in isoceles triangle.
Interior angels of triangle is 180, thus
180 - (72+72) = 180 - 144 = 36. This is the angel at the tip of the star.

Since I live "at the end of nowhere", amazon helps to fill the gap. Special items, like a certain brand of fish oil high in EPA or kelp to make dashi, are hard to find so I amazon it. It saves me a ton of time and gas to just reorder what I like.

I am sorry I posted this to the wrong thread. Having multiple windows open can be dangerous. As soon as I hit post, I knew something was not right. Sorry again.

Bean Dip for Homeschoolers
I've been passing around bean dip on the net for a few years. It was originally written for attachment parenting and alternative medical choice. I've revised it for homeschoolers who are facing varying levels of hostility towards their choices.
As an interesting related note, I find it telling that the spell check on my AOL email does not recognize "breastfeeding" or "homeschooling". That fact, in and of itself, is why bean dip is so needed. :)
Bean Dip:
I wanted to offer my "bean dip strategy" for homeschooling.
It's something I've learned in my years of parenting using alternative ideas. The specifics may change, but the principal doesn't. When setting boundaries, people (often moms) typically confuse setting the boundary with trying to convince the other person about how right they are in needing to set the boundary.
In setting boundaries, we don't need to convince the other person we are right and they don't have to agree about the boundary. We just need to be prepared to enforce the boundary, at any cost, using progressively more firm responses (if need be).
Here is an example:
I've found new moms often confuse boundaries and trying to convince someone of the *rightness* of their choices. They will send articles, links, books, cite statistics. All of these things send the message: this is up for debate and discussion, I may be swayed by you.
The best thing is to assert your boundary and *not* try to defend your choice. No books, articles, links, etc. If the person feels strongly enough *they* can initiate getting some information.
First, I learned early on that most of my choices were on a "need to know" basis. Most people don't "need to know."
Question: "What about socialization?" Answer: Got that covered, thanks! Want some bean dip?
Question:"They will need to function in the real world" Answer: "Yes! Thank you! Want some bean dip?"
"What about college?" Answer: "Yes, our children will be going. Thanks! Want some bean
dip?"
Now, with some people you will need to set *firm* boundaries. They will need to be backed up with action (like hanging up, leaving the room or even the event). If it's a pattern of intrusion, for example. Practice kind but firm responses:
"I know you love us and the children. We are so glad. Our education choices have been researched and made. I will not discuss it again"
Don't confuse setting boundaries with trying to convince someone of the rightness of your choices. New HSing moms often struggle with this. The boundary is that no one else has a right to tell you how to parent and create a hostile environment. You set boundaries by doing the above. New HSing parents often invite problems is by citing authors, studies and sites to "defend" themselves. Each time you do so, you create more time for discussion and rebuttal and send the message that your decisions are up for debate. Don't defend your choices beyond generalities, and then only once or twice. "We are quite comfortable with our choices. Want some bean dip?"
Finally, look them in the eye and say simply "I want us to have a good relationship. I want you to *enjoy* the children. I'll parent the child - you enjoy them. Let's not discuss this anymore. If you bring it up, I will leave the room."
One thing I want to add is to *carefully* chose who you vent/rant to about parenting issues. Homeschooling is like breastfeeding in a way. Normal struggles get blamed and dumped on homeschooling (like normal baby/adjustment issues get blamed on breastfeeding). People will attribute parenting issues to the fact of your homeschooling. The more aggressive/hostile ones will deliberately capitalize on the opportunity and will use your parenting challenge as a way to force their anti Homeschool agenda. So, be very selective who you talk to about the specifics on your life.

There are 2. One is for alternative parenting, particularly in the early years:
http://www.gentlechristianmothers.com/mb/index.php?topic=1988.0
The other was re-written as early childhood issues ceased to be an issue for me and homeschooling emerged:
http://happyhomeschooler.blog-city.com/read/212600.htm
The Bean Dip response, in spite of its name, was not meant to be a casual, quick change of subject. The heart of The Bean Dip response is establishing firm boundaries and not setting oneself up for debate, discussion and dialog.
Changing the subject (the Bean Dip offer) comes after setting the boundary. And, prior to the need to set the boundary is our responsibility. Let's say you co sleep. Don't invite discussion by offering that info. Let's say you homeschool. Don't invite discussion by asserting that your well behaved, courteous kids are a result of homeschooling.
There *is* a time and place and people with whom to have great, provocative discussions on these topics. The Bean Dip response was formulated for difficult family members, intrusive neighbors, casual church acquaintances and others with whom you feel discussion would be dangerous, fruitless, irritating, difficult or inappropriate.
You "Bean Dip" people when you assert yourself as the expert on your children and actively define your role in their lives and limit the role of other people. You "Bean Dip" when you are confronted with provocative topics ("What about socialization"?) and instead of defending with a long list of extracurriculars or a radical discourse on the inappropriateness of the school social hierarchy, you say "Yes, socialization is something we work on."
When you defend, you communicate that the topic is up for discussion or debate. For boundary less or boundary challenged people that giving them power to try to change your mind. With the boundary challenged, you don't want to give them the impression of that power. Dean Dipping them isn't about a fluffy change of subject, but about a firm deflection.
The final stage of Bean Dip includes a direct, firm and forceful message to BUTT OUT.
Anyway, maybe because I have such defined boundaries, the above doesn't come through correctly in my Bean Dip writings. I've read some things here lately that compelled me to post and clarify.-

I have not read all the responses so forgive me if this was covered.

I live near where the Potomac empties into the Chesapeake. My back porch thermometer read 68F. This evening, after sunset, it will start with ice/sleet then switch to snow, possible 3-7 inches. I am trying not to cry.
I know you Northern Gals are laughing at us since you get this all the time. I was born a Floridian and I will always be a Floridian so this is torture for me. :huh:

BTDT - I use very little makeup because I am sensitive to everything. (My dermatologist said I was one of the most sensitive people he sees.) I am over 40 with brown hair and green eyes.
It is important to start with a clean face. I gently was my face with Neutrogena transparent facial bar followed by Witch Hazel. I use either:
First Aid Beauty( http://www.amazon.com/First-Aid-Beauty-Daily-Cream/dp/B004R7N6NU/ref=sr_1_11?s=beauty&ie=UTF8&qid=1390168884&sr=1-11&keywords=first+aid+beauty )
or Earth Science Almond Aloe facial Moisturizer ( http://www.amazon.com/gp/product/B000Q43MLO/ref=wms_ohs_product?ie=UTF8&psc=1 )
At night I also use Jafra Elasticity Recovery Hydrogel under the lotion: (http://www.amazon.com/Jafra-Elasticity-Recovery-Hydrogel-Fl/dp/B004IAC7F4/ref=sr_1_14?s=beauty&ie=UTF8&qid=1390169324&sr=1-14&keywords=jafra)
The best foundation I have found is MAC skintastic mineral makeup. Go by the MAC counter to get a good color match and invest in their application brush. It provided great coverage, protects my face from the world (the sensitive thing) and does not bring out my wrinkles. I reorder from Belks.com with free shipping since the MAC counter is an hour drive away.
I slap on some lipstick, Revlon colorstay, and head out the door to face the day.
