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.

The start of this lesson involves a BIG write where students are provided with information on the water poisoning incident at Camelford and are asked with success criteria to explain how they could test to see if the water was safe to drink using knowledge from previous lessons in this topic. The second half of this lesson involves a learning check to see who is confident with writing and balancing symbol equations. On the back of this check confident students compete in a race with other groups of confident students to balance a series of ever increasingly hard equations. Students who are less confident work with the teachers in a focus group on balancing equation. I used this for an observed lesson and it worked really well. Save yourself some time and hassle and grab yourself 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.
