Mini Lessons: Science Secondary

In this lesson, Diana will teach you how the Earth rotates and revolves in space, and then she'll show you how to make your own model to answer the question: "How do day and night occur?"

In this lesson, you will learn why scientists organise living and non-living things in a logical order. Diana will show you how to construct a dichotomous key for classification, and give you a chance to try it yourself.

In this lesson, you will learn about a property of matter called density. Diana will conduct experiments to answer the question 'Why do things sink and float?', and she will teach you how to calculate the density of objects.

In this lesson, you will learn about how particles behave when they are exposed to higher temperatures. Diana will conduct experiments to show you how a gas, liquid and solid behave differently when they are heated.
