A Things of Science unit from 1963. A lot of the early Things of Science units appear to be about materials. Copper, Silk, Cotton — just to name a few. Although a little unusual this unit continues i that vein. Looking at the list of things that are supposed to be included, I may be missing some bits of wood, but otherwise the yeast appears to be there.

Here is the booklet:

Another Things of Science unit from 1963 — this one on copper. The unit I purchased off eBay appears to be more or less complete.

The “things”:

By 1970 Things of Science had become much more colorful — the iconic yellow-gold paper swapped out for other pastel hues.

The “things”:

Another Things of Science unit that contained seeds. In fact, this particular one I got off of eBay has the seeds from 1969. Cool.

And now, thanks to this unit, I know what sorghum is.

The “things”:

A Things of Science unit on taste. While this unit arrived with the contents in tact, I decided against opening the gum (etc.) from 1969 and trying it.

The “things”:

I assumed a Things of Science unit on gravity would be thin, but I forgot about pendulums, ellipses, etc. Things of Science didn’t forget. A 32-page booklet is evidence of the amount of information squeezed into this (another excellent) unit.
