As a former chemistry teacher, I helped the students construct a chemistry reference notebook. This notebook contained examples of problems from many chemistry concepts. The students were able to refer to it throughout the year. Many students saved the notebook and used it as a reference source for their freshman college chemistry class. Several students thanked me for the notebook saying that it helped them thru that hard college class.. (Students take high school chemistry as a sophomore or junior. It can be two or three years before they take college chemistry. Needless to say, they can forget some chemistry in that time frame.)
I am reconstructing and updating this reference notebook. I am now calling it a chemistry interactive notebook with foldables, practice problems and answer keys. I will periodically add sections to the notebook until the year is complete. Prices will be cheap.
This product covers five topics: density, percent error, temperature conversions, characteristics for a compound and characteristics for a mixture.
