How are Flow Conditions in Volcanic Conduits Estimated?
chuck connor
SSAC Physical Volcanology module. Students build a spreadsheet to calculate velocity of rising magma in steady-state Plinian eruptions using conservation of mass and momentum.

Creating a Connection between Everyday Life and Stoichiometry using ChemPrime
This page is authored by Lisa I Smith, M.S., North Hennepin Community College, based on participation in the ChemEd DL summit hosted by the University of Wisconsin - Madison and Catholic University of America.
This activity allows the student to access a webpage that provides examples of stoichiometry using terminology and objects they use in their everyday life. This activity can help a student make a connection between the complex chemical concept of stoichiometry and their current knowledge.

Understanding Acid-Base Titrations using Microsoft Excel
William Thomas
This exercise uses a PowerPoint learning module to help students understand the relationship between pH and hydronium concentration in acid-base titrations.

Radioactive Decay and Popping Popcorn -- Understanding the Rate Law
