The extraction...

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...

Simon Quinnell demonstrates how to use a microscope and how to focus an image.

Purpose: Younger students often have considerable difficulty in making scientific observations when using a microscope. The nature of microscopy makes it challenging for teachers to be sure that students are observing the intended image. Using a mobile device to photograph an image through a microscope can be used...

This activity allows students to practice carrying out magnification calculations and learn the difference between magnification and resolution.
