In the Frying Ice formative assessment students explore the three phases of matter. This formative assessment targets the question “What cues are used to differentiate matter types?” The target of this formative assessment was for students to demonstrate their understanding of the three states of matter and how the particles in each state react when heated.

The fire story formative assessment is used to explore students' thinking about the question "what affects chemical change?" through a real-world problem. This formative assessment specifically probes students' understanding of energy and phase changes. There are several different explanations using different chemistry concepts that could be used to explain the phemomenon explained in the story.

As we continue to make plans to teach during these uncertain times we have been compiling a list of both new and previously published ChemEd X posts and resources that will be useful to readers while teaching during the COVID-19 pandemic. Do you have an activity, strategy or idea to share with the community? Is there a resource you would recommend? We welcome contributions. This list will grow, so check in again to see what has been added.

Ice core science is truly cross-disciplinary as it draws extensively from chemistry, geophysics, geology, engineering, oceanography, microbiology, statistics, a deep understanding of historical events, atmospheric science, and climate science. And general chemistry topics include solubility, concentration, phase diagrams and changes, and stable isotopes in addition to many others. Let's take a first look at how ice core science can be used in teaching chemistry.

Formative assessment is an important component of teaching as it enables teachers to enhance student learning. The written work that students produce on formative assessment tasks can be used to uncover student thinking and inform the decisions teachers make on how to support individual student learning.

Potential enhancements to soda-based demonstrations of volcanic eruptions are described. Depending on the specific demonstration setup, outgassing of carbonated sodas can represent low-viscosity lava flows or more violent production of pyroclastic materials. These simple demos can be used as stand-alone experiments or in concert with other activities.
