Science Practice: Using Mathematics and Computational Thinking
Stoichiometry - A Free Virtual Chemistry Lab Activity
Josh Kenney | Tue, 12/15/2020 - 09:38
In this virtual activity, a video introduces stoichiometry and guides students to think conceptually using a simple baking analogy. Afterward, stoichiometry calculations connect to the analogy, that are then reinforced with a simple experiment. Finally, students explore a PhET simulation to deepen their knowledge.

This activity allows students to see many different types of scales in order to become proficient at measuring and determining how many digits to record in any measurement, whether it be volumes, masses, lengths, etc.
Introducing Density - A Free Virtual Chemistry Lab Activity
Josh Kenney | Wed, 09/16/2020 - 11:24
The author explains a virtual chemistry lab activity for use in a high school chemistry class. This activity is an excellent way to introduce measurements, significant figures, and the concept of density.
Exploration of Gas Laws Using Atomsmith Online
Lowell Thomson | Fri, 09/11/2020 - 11:21
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.
Filling the Void: Options for Authentic Investigations Online
Ben Meacham | Wed, 07/29/2020 - 10:28
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.
Chemistry Experiments with the Flame Tube
Tom Kuntzleman | Tue, 05/26/2020 - 12:37
The Ruben's Tube (also known as a Flame Tube) is a classic experiment used in physics classes. There's also a bit of chemistry to be learned while experimenting with a Ruben's Tube...
Limiting Reagents and Gases
Chad Husting | Sun, 02/02/2020 - 06:53
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.
