Science Practice: Engaging in Argument from Evidence

Exploration of Gas Laws Using Atomsmith Online

Using the online simulation tool (Atomsmith Classroom Online) and the ADI framework students investigate the properties of gases, along with two gas laws. An ADI "whiteboard discussion" helps in getting students to really process what the results of experiments mean to us as chemists - and how this leads to expanding our understanding of matter. This activity lends itself to an online classroom.

Color Changing Coke and Mentos

What's a better way to start the new school year than with some new experiments? Learn how to use a variety of color changing experiments to teach students about the Diet Coke and Mentos experiment, acids, bases, chemical and physical changes, and climate change.

Filling the Void: Options for Authentic Investigations Online

With the school year quickly approaching, science teachers will at some point need to decide the role of laboratory investigation within their new learning environment. To help this decision-making process, the author focuses on two available options that he believes have the greatest potential for offering a legitimate approach toward authentic investigations in a digital environment.

Making a (big) eruption with chemistry!

As teachers, we can leverage fruitful discussions about chemical control with students to elicit more about students' initial ideas and ways of reasoning. From asking students to clarify their own thinking, we can identify students’ own productive ideas that we can capitalize on to advance their thinking.

A Multi-Colored Equilibrium Experiment

Solutions of copper (II) dissolved in acetone are easy to prepare, and can display orange, yellow, green, and blue color depending upon conditions. Such solutions allow for a variety of demonstrations and experiments that illustrate principles of chemical equilibrium.
