I know that the blog hasn’t had the big science focus that I had a couple of years ago. However, we do still do science regularly with a small group and I facilitate hands on learning and occasionally experiments. Since we did a full cycle of science topics over the course of four years, I decided to ask the kids what they wanted to revisit. First, we did some physics, but next they wanted to take on chemistry, so that’s what we’ve been doing for the last couple of months.
I looked at a lot of different potential resources for teaching chemistry and I thought about using Inquiry in Action from the American Chemical Society, but it seemed too simple with too many things we’d done in the past. I considered doing The Elements from Ellen McHenry, but it was so focused on a single aspect of chemistry and after doing most of The Brain, I knew I liked her products, but I wasn’t sure I wanted to tackle this particular program. I thought about doing chemistry the way we always have by doing our own demonstrations and explorations. I bought an excellent book called 150 Captivating Chemistry Experiments Using Household Substances with that in mind. However, in the end, I decided to go with the American Chemical Society’s free middle school program. Some of the information has to be scaled down a little since I am working with a group of mostly fifth graders and a few younger kids. However, it has been interesting to use an actual, full science curricula for the first time ever.
The program is not long enough to take the whole year. There are six chapters. Doing the bulk of the experiments from each chapter with a small group is taking us about two weeks per chapter. If I had the kids filling out every table and worksheet, this would be different, but often we do most of the hands on stuff together as a demonstration and discussion and I choose one or two activities to have them really do fully on their own with more writing and recording. I haven’t had them do many of the worksheet elements at all. Instead, we’ve talked about the questions on them. However, even if I did, I doubt it would take a full year.
Each chapter is divided into sections. The sections have student and teacher pages. The student pages are extensive instructions with worksheets and tables to fill out. There are often sections with additional science background for the teacher, which I found very useful. Each chapter has a section of student reading, which we have used for each chapter. I like the progression of information, both overall in the program and within each chapter. Sometimes the organization of the information feels a little overwhelming. It would be much more usable as a physical text, but since I have only the pdf, there is a lot of scrolling to do, which isn’t always ideal. There is multimedia available for every chapter, however those pieces are pretty simplistic. Most of them are short animations of models of molecules interacting to imitate what students have just done in their hands on explorations and experiments.
The heart of the program is really the hands on element. I liked that the experiments are tied very closely to the information. For the most part they have “worked” the way that we expect. This was not a “household substances” sort of program. Most of the things we’ve needed have been things we have around the house like water and salt, or things that are easy to get like Epsom salts, rubbing alcohol, and clear plastic cups. However, many experiments also call for chemistry glass like graduated cylinders and a few call for chemicals you need to special order or seek out particularly, like calcium chloride. Also, special equipment like a ball and ring apparatus, density rods, and density cubes is called for. I spent a decent amount on supplies at Home Science Tools. However, I figure we’ll be glad of having the science glass later on and all of the special equipment I bought turned out to be great fun. The ball and ring apparatus shows how molecules expand when heated. We did that demo several times over because it was fun to see. And the density cubes were great fun to play with. We really enjoyed having them, so they were worth the money. The fact that the program is free helps offset some of the costs of buying classroom type equipment.
Overall, I really like this program. We have shied away from science curricula because nearly everything I’ve seen has felt like busy work with very little hands on components and only poorly written text. This program is really all well-organized, worthwhile experiments. I would still love to have a more engaging, longer text than what the ACS program has, but at least it’s succinct and well-written. I’ve also had to supplement with videos I find myself, but we’ve found a lot of great ones. We’ve especially been enjoying many of the TED Ed videos and we’ve returned to using a lot of the old Eureka! shorts, which have covered the information perfectly. Here’s the TED Ed chemistry playlist. And here’s a playlist for all the Eureka! videos.
I think we might have been better off waiting a year or two to try this program so that some of the things I’ve had to simplify could have been more fully explored. But that’s what happens when you put the kids in charge of what they want to learn. Overall, we’ve been pleased and it gives me hope that while elementary science programs weren’t our cup of tea, we may find more options for serious home science study in the upper grades.
