Blaschka Glass – A History of Glass Models

Some of the most amazing glass objects were created at the turn of the last century, not this one. Specimens and models of flowers and sea creatures so realistic you can hardly believe they were made of glass. These pieces were made by Leopold and Rudolf Blaschka, a father and son glass working team. Their work can be seen in the museums at Corning and Harvard as well as other places around the world. I stumbled on a video on You Tube that provides a history of Leopold and his son and their work. I highly recommend watching it if you love glass.

When Harvard saw the flowers and plant life that Leopold had created he was commissioned to create models of sea creatures for the Harvard Museum. I am certainly not doing their story justice so I highly recommend you learn more about the Blaschkas. I know it has made me appreciate the glass technology I am allowed to work with.

I guess moss and lichen are more things that you see in the spring than in the summer, but there are some deep shady parts of our yard that stay mossy all year, and summer is a fine time to look for plants that like to live in shady, wet areas.

Raising Up Wild Things has a really pretty set of printables to use for a moss and lichen unit study.

And just in case you’re like me and don’t really know the difference, moss is a plant that grows in damp wooded areas, while lichen is a combination of fungus and algae that live together. Lichen can live in different environments but are often found in places where you would find moss, too.

The printable includes drawings of some common moss such as sphagnum moss and wood moss, as well as common lichen shapes (crusty, leafy and shrubby). There are good sized images you can print out and laminate to use to compare to specimens you find when you are exploring nature.

There’s also a forest floor coloring page and a printable journaling page where kids can write or draw their observations and there are a few questions older kids can answer.

You can use these when you go on a walk in the woods (or the back yard) to talk about what you are seeing, or combine them with other resources to talk about things that live in the forest. Check them out at Raising Up Wild Things.

This PDF from the Morton Arboretum has a bunch of pictures of different kinds of moss and where to find them, which could also be helpful in your studies. Learn more about lichen, including what they are and what they are not, in this article from the US Forest Service.
