Students will learn to give examples of emulsions and will perform a practical activity to determine the best agents to create an emulsion. Basic ingredients needed and could be performed in plastic cups (test tubes are best). The worksheet allows students to structure their research and also self assess it at the end.

Perform the pH practical activity to test the suggested chemicals and / or display slide 3 for those that you cannot test. Print slide 2 for students who must colour the pH scale and place the chemicals alongside the periodic table. As a plenary ask students to record which chemicals will neutralise each other (e.g. wasp sting --> Bee Sting).

Introduce ionic and covalent bonding using the animated PowerPoint. Get students to explain what is happening at each stage. Worksheet challenges students to recall electron arrangements for atoms and identify products of reactions. Finally students identify the type of bond formed. As an extension, students could give their own examples. This lesson should follow an introduction to atomic structure.

2-3 engaging lessons that make learning the periodic table more accessible. Ideal for low to middle ability groups. Students begin with finding the location of elements in the periodic table using the grid references (print 2 slides per sheet to keep costs low and have couple of examples of elements to hand - Zinc, Copper, Carbon, Aluminium). Students then learn about the structure of atoms and link this to the layout of the periodic table. Students finish by drawing atoms and consolidating learning through a game of Atom Trumps.

Students research factors for or against using regular cooking oil as a fuel source. Students present their findings to the group and the teacher is able to monitor any changes in attitude during the course of the lesson. Resources are accessible and presented using familiar scientific formats.
