Lab kits for homeschooling chemistry

In my previous post, I mentioned the Advanced Microchemistry kit, from Quality Science Labs.

Another kit that has been mentioned in e-mail is one that I actually looked at earlier and forgot to include in yesterday’s post: the CK01 kit from the Home Scientist.  Instead of 16 labs, it is set up for 39 labs, and it costs only $174 instead of $220.  They also provide the lab manual on-line for free, so it is easy to see what the labs are and whether they are worthwhile.  They also do one other very clever marketing ploy—they sell the same kit for $5 more including a second set of splash goggles for the parent.  Since any sensible home school teacher will be nearby while the labs are being done, including a second set of goggles is just good sense.

Let me compare the 2 kits side-by-side:

The Quality Science Labs kit has some more expensive items (the digital scale, the multimeter, and the digital thermometer), but also includes more common household stuff and fewer chemicals. I already have a multimeter (better than what they provide), and a digital scale that measures to 0.01g is only $10. I’m not sure a digital thermometer is any better than the alcohol-based thermometers I already have (or that come in the other kit). If we need higher precision or to record over a time period, I already know how to set up a thermistor with the Arduino data logger.  The Home Scientist kit has somewhat more dangerous chemicals (higher concentrations of the strong acids and bases, for example).

Right now, it looks like the CK01 kit is the better buy for us, and I can read the manual to see if the experiments align with the new AP chem curriculum.

Neither kit provides a heat source, so we’ll either use the gas stove or buy a small alcohol heater to work outside.  We also need to get gloves, and various household supplies (like distilled water, distilled vinegar, …).  Both kits have a list of needed supplies—the list for the CK01 kit is much longer, probably because it is designed for twice as many labs.

Based on this side-by-side comparison, I think I’m more likely to get the CK01 kit.  It seems to have more of the stuff I’d need and less of the stuff that I already have.  I also like the marketing better (full details of the kit and the lab manual free on the web site).
