Is your class in another dimension with regards to dimensional analysis? Give them some extra practice with a straightforward activity. Learners convert units by following concise step-wise examples, including setting up the...

Don't overreact! A simple experiment demonstrates chemical reactions as scholars mix chemical solutions and metals in a large well plate. They note all changes to the metals, solutions, precipitate, colors, and more. A full data table...

Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...

The team at Periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about the first useful metal on the periodic table, magnesium. It famously burns very brightly when exposed to flame. [6:36]

In this lab experiment students are asked to determine the standard molar enthalpy of formation of magnesium oxide, MgO. Students are asked to use Hess's Law and the enthalpy changes of several other solution reactions during this...

This lesson focuses on plant disease caused by mineral deficiencies including nitrogen and magnesium.
