We finished 7 of the 14 sections of the CK01A Standard/Honors Home School Chemistry Laboratory Kit by Home Scientist LLC. We spent 9 (five hour) class days to cover the material with 12 high school homeschooled students. We could have covered more material, but we took our time so that the students understood the material and carefully documented the procedures and results.
Here's what we covered:
1. Introduction
Getting Started
Kit Contents
Materials You Provide
Where to Work
Laboratory Safety
Final Words
2. Keeping a Lab Notebook
Topic I. Separating Mixtures
Session I-1: Recrystallization
Session I-2: Chromatography
Session I-3: Solvent Extraction
Session I-4: Salting Out
Topic II. Solubility and Solutions
Session II-1: Solubility as a Function of Temperature
Session II-2: Conductance of Ionic and Molecular Solutes
Session II-3: Colligative Properties of Solutions: Boiling Point
Elevation and Freezing Point Depression
Topic III. Chemical Reactions and Stoichiometry
Session III-1: Observe a Composition Reaction
Session III-2: Observe a Decomposition Reaction
Session III-3: Observe a Single Replacement Reaction
Session III-4: Observe Double Replacement Reactions
Session III-5: Stoichiometry of Double Displacement Reactions
Topic IV. Reduction-Oxidation (Redox) Reactions
Session IV-1: Observe Oxidation States of Manganese
Topic V. Acid-Base Chemistry
Session V-1: Determine the Effect of Concentration on pH
and the pH Range of Indicators
Session V-2: Determine the Molarity of Vinegar by Titration
Topic VI. Chemical Kinetics
Session VI-1: Determining the Effect of Temperature, Concentration,
and Surface Area on Reaction Rates
Session VI-2: Determining the Effect of a Catalyst on Reaction Rate
Session VI-3: Determining a Reaction Order
Topic XIV. Synthetic Chemistry
Session XIV-1. Synthesize Esters
We liked the kit and are disappointed that we couldn't finish it this summer. We are hopping to repeat our Chem Lab Camp next summer.
There are a few elements that have made this Do-It-Yourself Chemistry Lab Camp such a success.
1) We started with a good science kit.
2) We found a master teacher who is knowledgeable and excited about the material.
3) We had a good class size and kit-to-student ration. (12 students with a complete kit for each 2 students to share
plus a kit for the teacher)
4) We rotate lab partners every section.
5) Our classroom (my garage) has easy access to a laundry sink,
an ice-maker, and enough electric outlets. We did blow quite a few
fuses, but with extension cords running to plugs on different circuits,
things have worked out.
6). We bought a hotplate (6) for each lab partnership. Luckily, they were on sale at Walgreen's for $12 each.
7) The students were all good kids who were eager to learn.

Without a doubt, I believe that undergraduate research was the most valuable part of my education. Learning about a Chemistry reaction in a class is a much different experience than having to carry out the experiment yourself
I recently came across your blog and have been reading along. I thought I would leave my first comment. I don’t know what to say except that I have enjoyed reading. Nice blog, I will keep visiting this blog very often.http://nahrs.in/our_services.aspx?id=8
