This lesson is aimed at KS3 to help to develop students investigation skill where they have to identify and categorise the different variables in the experiment, choose the control variables and explain why. The practical is simple and fun where they see how much stomach acid (HCl) branded and unbranded heartburn tablets neutralised. This is a self contained lessons with all instructions and worksheets built in. This will easily last a double period, so grab yourself a bargain and save some time.

This lesson builds students up to naming compounds made from non-metals and metals, which end in-ide and then moves on to naming compounds which contain a non-metal, metal and oxygen which end in -ate. This worked well for a low ability year 11 class, but scaffolding could be taken out to provide more challenge. A worksheet is included and can be differentiated accordingly to test the understanding of different learners,

This lesson introduces student to the concepts of relative atomic mass and relative formulae and uses this as a platform to introduce calculation of empirical formulae. The calculation of empirical formulae is introduced through a methodical tabled approach which students can master readily and then attempt with out the framework. They then get to practice their calculation on a made up compound made of sweets. If they get the empirical formula correct they get to eat the sweets. Save yourself some time and grab a bargain.

Lesson 1 looks at investigating through a practical why some waters lather better than others and concludes with a BIG write/6 mark question that has success criteria which can be readily marked by yourself or the students. Lesson 2 - Introduces students to the idea of calculating concentrations of solute in solutions. All worksheets are provided. Save yourself some time and grab a bargain.

An introduction Key stage 3 lesson on acids and alkalis, based on the new national curriculum framework. Students identify physical properties of alkalis and acids - soapy to touch, sour tasting Students identify chemical properties from diagrams and formulas of alkalis and acids. Small experiment with requisition list included - testing acids and alkalis with red and blue litmus paper.
