In this lesson, students will investigate some of the meteorites and associated rocks in the loan box. They will test them for magnetism, do a visual analysis and measure their mass to calculate the densities of their items. This activity is particularly geared towards getting students to estimate the volume of the...

A Catalyst article about careers in meteorology (weather forecasting) and climate science. The article explains the work of EMARC (Environment Monitoring and Response Centre) and provides some advice on training as a meteorologist.
