Molar Volume of Gas - Lab Tip

Face to face professional development provides the opportunity for teachers to learn from and share with other teachers. This post provides an example of one of the many great ideas that I have learned from other teachers. 

Separation and Choices

I allowed my students to choose between two separation type laboratories. About two thirds of the class chose to separate the flavoring out of a grape of cherry soda. The rest of the students used paper chromatography to determine if red-40 dye was in a specific type of candy.

That’s What Scientists Do!

As I began to prepare my labs for this upcoming year, I decided to put a bit of a twist on a previous density of a block lab I had used in the past entitled the Measurement Challenge that is sold by Flinn Scientific. It can also be used to find the mass of a block given the materials density and requiring students to measure and calculate the blocks volume. My added twist resulted in great scientific discourse.
