Types of Ionizing Radiation Lab and Simulation

Lauren Stewart | Fri, 04/27/2018 - 19:28

Radioactivity is a topic in chemistry that can be difficult to teach if you are looking for a hands-on, data-driven approach. Safety and cost concerns often prevent students from having an inquiry-based experience with the topic. In this post, I will share how I am able to give my students an authentic lab experience for them to determine there are three types of ionizing radiation without direct instruction.

The International Scholastic Journal of Science - Publishing the original research of secondary school students.

Lowell Thomson | Thu, 04/26/2018 - 17:00

The International Scholastic Journal of Science is an online, open-access journal that provides the opportunity for secondary students to publish entry-level research and become part of the scientific process. In this blog post I will share information about ISJOS and encourage you to find students that are interested in publishing.

Confessions of a Part-Time Modeler

Roxie Allen | Wed, 04/25/2018 - 11:12

In the summer of 2016, there was a Modeling WorkshopTM for High School Chemistry just before BCCE in Colorado. I already had planned to go to BCCE, so I took the plunge. Two weeks of daily instruction and labs in student mode as well as teacher mode debriefing was exhausting and exhilarating at the same time. I left with a folder and flashdrive of curriculum resources provided by AMTA (the American Modeling Teachers Association.

The Chemistry of Weight Loss

Tom Kuntzleman | Tue, 04/24/2018 - 18:48

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.

POGIL in the High School Chemistry Class: Objectives, Practices, and Outcomes

Kristen Drury | Thu, 04/12/2018 - 14:56

All too often teachers use POGIL activities as worksheets when the teacher is absent, busy work to review a topic, or handouts for homework. However, using the POGIL activities in this manner does not allow the students to reap all the benefits of the activity. This article is designed to give you a glimpse into what the POGIL process can do for you.
