A fully resourced, plug-and-play Elements, Compounds & Mixtures unit designed for the AQA GCSE Chemistry (9–1) specification. This FREE sample unit contains everything needed to teach, practise, ...

Homogeneous and heterogeneous mixtures are the focus of this segment as well as solutions and alloys. Obtain, evaluate, and communicate information about the chemical and physical properties of matter ...

This video explains the periodic table, containing all the known elements arranged in groups and periods. Elements in the same group of the periodic table show trends in physical properties, such as ...

In this segment, students learn how to separate particles from a mixture while completing a candy chromatography lab. Obtain, evaluate, and communicate information about the chemical and physical ...

Chemical bonds are generally divided into two fundamentally different types: ionic and covalent. In reality, however, the bonds in most substances are neither purely ionic nor purely covalent, but lie ...

Up until now we have been discussing only the elemental forms of atoms which are neutrally charged. This is because the number of electrons (negative in charge) is equal to the number of protons ...

This video demonstrates how paper chromatography can be used to identify what’s in an ink, in a practical experiment. Chromatography is a technique used to separate a mixture of soluble substances, ...
