Hi Linzy,
I will try to answer your question as best I can. I am having a bit off a block at the moment. Anyways, have you looked into Real Science 4 kids High school chemistry textbook? The goal of Real science 4 kids is to reach children of all grade levels science concepts they will see in college. And also teach the college concept and vocabulary awareness of these such topics in these grade levels, so when the child/ dren encounter this topic information in college, they will be better prepared. Here is the link:

I hope this helps.
