Learn how to create cognitively demanding tasks for your classroom during this Knowles Academy virtual course.
Did you know that sand can be converted into a mixture of gases that spontaneously ignites in air? The procedures involved are relatively simple to perform, spectacular to observe, and relate to a rich assortment of chemical principles.
Many novice students struggle to see elements' valence electron configuration trends across the rows and columns on the periodic table. There are many diagrams and explanations available as resources for students however, a deeper understanding may be possible when students discover these trends independently through a game called Electron Configuration Battleship.
Stephanie O'Brien shares lessons learned and strategies for utilizing choice boards in chemistry classroom.
What is the pressure inside a bottle of soda pop? Read this short article to find the surprising answer to this question, and also to learn how to do an experiment to answer this question for yourself!
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.
Several resources are available to support teachers as they incorporate science practices into their curriuculum. The author shares how he and his colleagues focused on improving their coverage of the practice of planning and carrying out investigations.
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!
In order for students to be fluent enough with the CCCs and core ideas to use them to support their arguments, we teachers need a way to help students become familiar with them.
I facilitate a working group of chemistry teachers in the New York area and we recently created our own activity surrounding the topic of oxidation. The goal of the probe was to force students to think about what the meaning of oxidation is, as well as to allow students to engage in the science and engineering practice of argumentation. This was an introductory lesson to my oxidation and reduction unit prior to students learning the terms oxidation and reduction.
