Science Practice: Planning and Carrying out Investigations

Limiting Reagents and Gases

This unique microscale gas collection technique provides students with reasonably good data in a short period of time. Students have more time to analyze the data and communicate their findings. 

Chemical Kinetics with a Smartphone

This experiment in chemical kinetics can be conducted using materials as simple as a smartphone, hydrogen peroxide, sodium carbonate solution, and blue food dye! The experiment is useful when discussing the order of rate laws with respect to reactants.

Chemical Tests on Coins

Simple chemical tests are described that can indicate the presence of certain metals in coins. A wide variety of chemical concepts are involved. The experiments described are a natural fit for the 2019 National Chemistry Week theme of "Marvelous Metals!"

First Day Chemistry Engineering Activity

I just finished my first week of school, like many teachers in the Midwest. I work hard to get my Honors Chemistry students in a lab setting as soon as possible. It is difficult to find a perfect lab to do on the first or second day of school. In my mind, the ideal first chemistry lab would require no prior chemistry knowledge, involve interesting chemistry, address an NGSS standard, be relatively safe, not require expensive glassware or lab tools, and reinforce positive class norms. I have found engineering labs fit the bill! I don't know if I have found the "perfect" lab, but I have found something close I want to share!

Gas Laws and Deflategate

If you are looking for ideas to create an authentic opportunity for students to apply their knowledge of gas laws while integrating some of the most important science practices, then this activity may fit your needs.

The Liquid Nitrogen Cloud

Have you ever seen the liquid nitrogen cloud? Do you wonder how the cloud forms when hot water is thrown onto liquid nitrogen? This post explores the liquid nitrogen cloud and possible explanations for its formation.
