Some teachers do not like the idea of letting students do a "redo" on an assignment. It can, if done carefully, have a positive impact on students learning and the culture of the classroom.
Learn a simple way to relate the heat equation (Q = mc∆T ) to climate change.
To accommodate learning in the time of SARS-CoV 2 different hybrid instructional strategies have been deployed. This blog describes experiences with the HyFlex model.
"Google Forms" can be a powerful tool to assist both virtual and face to face students in chemistry.
Determining the empirical formulas of ionic compounds based on charge balance is often a challenge for beginning chemistry students. Many visual aides have been developed for this purpose, from repurposing commercial interlocking bricks to custom 3-D printed bricks. This article describes yet another option– upcycled can carriers.
Are you expecting too much or little of your students working from home? Perhaps this blog post will help with setting expectations and evaluating how much time your students should devote to online learning. And hopefully, the suggestions in this blog will help in lowering your stress levels.
Reflections of a high school teacher after one week of teaching in the hybrid schedule. Download a copy of the author's Class TImer and Brain Break Google slides.
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.
Many teachers have students draw models and diagrams to help them illustrate how matter behaves. Teachers can uncover and address possible misconceptions quickly using this strategy. The author describes how to create interactive particle diagram activities that are easy for students to use online. This strategy is applicable to almost any particle diagram and should be useful for teachers during virtual lessons.
Two important types of information obtained from ice cores comes from the bubbles in the glacial ice and the stable oxygen and hydrogen isotopes within the frozen water molecules themselves. This post describes how the bubbles (air pocket 'fossils') and stable isotopes are used to determine the concentration of gases in the ancient atmosphere, particularly in relation to past temperatures.
