In this video, we explore the structure of animal cells. I take you through the key structures and their functions and then give you a cell to label yourself.

In this video, we look at elements, compounds, mixtures and molecules. First we look at the idea of an element, using examples from the periodic table. I then show you the definition of a compound and what is meant by fixed proportions. We then explore the definition of a mixture and the differences between mixtures and compounds. Finally, we look at what is meant by the word molecule and see how molecules can be elements or compounds.

In this video, we look at the properties of metals and of alloys. First we explore the structure of metals, looking at metallic bonding and the sea of delocalised electrons. We use this to explain why pure metals can be bent and shaped, why metals can conduct electricity and heat and why metals have high melting and boiling points. We then look at the structure of alloys and use this to explain why alloys are harder than pure metals.
