Paper Snowflakes to Model Flat Symmetrical Molecules

Flat, symmetrical molecules can be modeled by folding a sheet of paper, cutting patterns into the folded structure, and unfolding to produce the flat paper models. The finished models resemble paper snowflakes, but have a variety of rotational symmetries. Template patterns for several molecules are available for download in the Supporting Information.

A Polystyrene Model of Polystyrene Tacticity

Thin sheets of polystyrene can be patterned with permanent markers to represent repeating units of the polymer and then shrunk down in size using heat. The shrunken models of the repeating units can be connected with a string and then flipped into positions to demonstrate different types of polymer tacticity.

Lithium Battery Flame

Inspired by a recent article in the Journal of Chemical Education, Tom Kuntzleman attempted to extract lithium from a coin battery, and to use the extracted lithium to produce a pink flame.

Free Climate Science Workbook for Teachers

The Wisconsin initiative for Science Literacy has published Science Climate Concepts Fit Your Classroom - A Workbook for Teachers. This is a free online Workbook, readily available for secondary teachers and college faculty. This workbook includes many hands on activities that incorporate traditional science classroom concepts within the context of climate science.
