This lesson revolves around a practical where students have to experimentally determine which site of salt production presents the best yield of salt. Students then use their results to calculate the concentration in g/dm. This is then built on in the following lesson to calculate mol/dm. Save yourself some time and grab a bargain.

This lesson encourages students to start thinking about continuous and discontinuous data with lots of concrete examples. They plot a human bar graph of favourite colours and then carry out a small experiment investigating how the volume of vinegar added to baking soda alters the amount of foam produced. This easily lasts a double lesson (100minutes) and is a really fun way to get students engaged with graphs. Save yourself some time and grab a bargain.

This is an introductory lesson where students use their prior knowledge of atomic mass (Protons and neutrons) to create their own definition for an isotope. They are then guided on how to calculate relative atomic masses from relative abundances of isotopes. Worked well with a middle ability year 9 class.

This is an introductory lesson to chromatography and the term pure. Students create a chromatogram of their own pen and compare it to others. They discover real life applications of this technique.

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 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.
