Measuring Surface Tension to Investigate Intermolecular Forces

Ben Meacham | Fri, 05/31/2019 - 22:38

Like most concepts in chemistry, intermolecular forces takes a bit of imagination and critical thinking to fully comprehend and apply when explaining a variety of situations. Though demonstrating the presence of these forces in a simple and explicit manner can easily be done, I wanted to change how I introduced IMFs a bit this year by focusing on a more data-to-concepts approach.

Whiteboards are great learning tools in a science classroom. With these instructions, you can make eight 24-in x 24-in whiteboards for less than $2.00 each! Instructions for simple whiteboard stands are included.

Elements, Compounds, and a Vocabulary Card Sort

How many of you could recite, word for word, a definition you learned in school? When you first memorized the definition, you could state “inertia is a property of matter”, or “density is mass over volume.” However, you struggled to apply it to a new situation and maybe you were unsure of how to construct a model of what it meant.

High-Impact Strategies for Implementing Next Generation Science Standards

Ryan Bruick | Tue, 03/05/2019 - 09:03

Like many members of the ChemEd X community, I am working with colleagues to teach and assess the Next Generation Science Standards in our high school’s general chemistry course. We are invested in engaging our students in Three-Dimensional Learning. This article aims to introduce readers to four of the high-impact shifts in mindset and practices we believe are helping our students learn to be better scientists.

NGSS-ify Alka-Seltzer Rockets

Given a guiding question, students determined what they wanted to test, did the experiment and got their CER boards ready for review. Instead of a regular argumentation session, we had a glow and grow session, where students had to provide positive and negative feedback for each board.

A “Science Reasoning Rubric” to Support Argumentative Writing

Dustin Williams | Fri, 01/11/2019 - 19:10

I put together a Science Reasoning Rubric that can be used for many writing prompts in a Chemistry class. It can be used whether a prompt is more suited toward a claim or an explanation. I like that the rubric can be used for lots of the writing tasks students will encounter in a Chemistry class. This means students get used to seeing it, and this consistency is helpful as students write explanations and claims throughout the year.
