The Diet Coke And Mentos Reaction – Having A Literal Blast!
Yvonne Clifford | Mon, 01/16/2023 - 10:28
The Diet Coke and Mentos reaction is used as the basis for this hands on experiment. Students work in groups to research, test, and adapt as needed with the goal to get the highest possible geyser!
The BCE (“Best Class EVER”) - Dry Ice Day
Yvonne Clifford | Mon, 12/19/2022 - 08:01
That it was the "Best Class EVER" seems to be the common refrain every year by most every one of Yvonne Clifford's students over the past 30 years after the Dry Ice Day. This is an engaging chemical to bring to the chemistry classroom or an outreach event because many concepts can be applied and it affords a great deal of fun and excitement!
Surprising Shrinking Styrofoam Stick: Using the Gas Laws to Get a Square Peg into a Round Hole
Dean Campbell | Thu, 11/10/2022 - 16:45
Polystyrene foam sticks with a square or rectangular profile will not fit into a round target hole (e.g., the opening of a soda bottle) at room temperature. However, they do contract sufficiently in contact with liquid nitrogen to fit into the hole and produce a simple demonstration of Charles’s Law. Many other polymer foams do not shrink under these conditions, but still provide opportunities to discuss and explore their structure and chemistry.

Stacks of LEGO bricks can be used to illustrate the composition and pressures of various planetary atmospheres. Guides for the construction and use of these atmosphere sticks are provided.
Real vs Ideal - Do Students "Get It"?
Ben Meacham | Sat, 05/22/2021 - 23:49
Allowing students to confront the failure of a model and then helping them construct a new or slightly modified model to account for new observations is at the heart of the process of science. Ben Meacham shares one approach that can be deployed with a variation of depth, making it attainable for anyone learning about chemistry.
