Gas Laws

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.

Card Sort Hacks

Card sorts are a great way to bring powerful retrieval practice into your classroom. You will find several Card Sort Hacks you can use to step up your game! You can even share these digitally to students to cut and complete at home. 

Two Simple and Cheap Illustrations of Phase Equilibrium and Vapor Pressure

Kaleb Underwood | Sat, 08/04/2018 - 12:37

A favorite demonstration is to boil water by lowering the pressure in a bell jar using a vacuum pump. Unfortunately, purchasing a bell jar, vacuum plate, and vacuum pump can run upwards of $1,000 which poses a hardship for many teachers. Here are two simple and inexpensive demonstrations of phase equilibrium and vapor pressure.

The Chemistry of Weight Loss

If you want to lose weight, you have to burn calories. Anyone who has gone on a diet knows this. But when someone loses weight, have you ever wondered where the lost mass goes?

 

Using an Argument-Driven Inquiry framework for student exploration of gas laws

lowell Thomson | Tue, 04/17/2018 - 21:18

Based on some interactions here on ChemEd X and Twitter, I have been looking for ways to have students generate more questions, ideas, and investigation methods. (See a list of relevant links below.) Some of this is inspired by Argument Driven Inquiry, while some of it is simply my own quest to move further away from being the sole source of information in the class. In this blog post, I would like to talk about how I addressed gas laws using Atomsmith Classroom Online as an investigative tool in place of lab work I did previously using the Vernier gas pressure sensor.

 

Incorporating Authentic Assessments in Chemistry

Ben Meacham | Mon, 04/16/2018 - 14:27

Recently, my district made a commitment to helping its teachers reflect and rethink their grading and assessment practices. One of the phrases I kept hearing throughout our staff professional development sessions was authentic assessment. I understood (and agreed with) the basic premise—create more opportunities for students to perform tasks that demonstrate meaningful application of essential knowledge and skills. Doing so involves going beyond, or even potentially replacing, traditional summative assessments at the end of each unit.

Using Phenomenon-Based Inquiry to Begin Gas Law Study in an Introductory High School Chemistry Course

Ryan Johnson | Sun, 03/25/2018 - 12:42

Students can sometimes struggle to grasp gas behavior, as it’s much harder to visualize gases rather than readily available solutions, solids, or mixtures. Indeed, for many labs, if gas is a product, we’re often relegated to using balloons or gas columns to capture and measure the gases produced by reactions, which can be tricky or expensive. So this year, I tried something a little different when starting my intro chemistry students’ gas laws unit, and was very happy with the results.
