We moved on from talking about atoms to talking about molecules and chemical bonds. Since my kids are pretty young, this is just a basic introduction to how bonds are formed and made.
Building Molecules Worksheet: This is a free download.
The screen shot below shows 2 of 3 pages.
We spent several days building different kinds of molecules:
On the first day we built water, oxygen, hydrogen and hydrogen peroxide:
The next day the kids built carbon dioxide, chlorine, ammonia and acetylene gas:
And on the last day they built methane gas, ethylene gas, methanol (wood alcohol), propane gas, nitrous oxide (laughing gas), vinegar and others:
We used EIN-O’s molecule kit. It doesn’t have the best reviews on Amazon, but it was just fine for our needs. It comes with double-bonds (see the red oxygen molecule above) as well as the plain single bond pieces. It is a bit confusing that there would be more than one hole on the hydrogen (white balls), but I just told the kids that was how the balls were made and they were fine with that explanation.
Update: When we did Chemistry again in the Fall of 2015, I opted to get the Molymod MMS-008 Organic Chemistry Molecular Model, Student Set (50 atom parts) (affiliate link) We actually got the Molymod Teacher Set (111 atom parts) – (affiliate link) because we have 3 kids in our family). I would recommend getting a Molymod set because the bonds are flexible and you can do so much more with them.
We are using Real Science-4-Kids Chemistry pre-Level I (affiliate link) as our spine. LD will probably move to Level I Chemistry (affiliate link) soon. I love the cute drawings. This book explains chemistry in a way DD can really understand!
Again, if you’re interested in building the molecules we did you can download the worksheet I made by clicking on this link–Building Molecules Worksheet.

- The Size of Atoms – This was a great activity!! We started our chemistry unit a couple weeks ago. We’re doing lots of reading and really enjoying the books in the NOEO curriculum.We loved, What’s Smaller Than a Pygmy Shrew? (affiliate link) It takes a look at protozoa, bacterium, molecules and atoms — even talking about electrons, protons and neutrons… be sure to check out our activities from the beginning of our chemistry unit here.
