A challenging topic for some so this lesson has been scaffolded to start with word equations (acid + metal hydroxides (alkalis) and move towards symbol equations for the fast workers. Also includes some starter questions and some true or false questions at the end to finish off.

An excellent lesson that takes you through the basics of a titration and how to collect data from it. Includes method, blank data tables and relevant questions + the theory that goes a long with the reaction.

Core practical looking at how ph changes when you add a powdered base (calcium hydroxide) to an acid (HCl) in this case. Your own risk assessment must be done for this lesson

A beefy lesson which will probably tale a double session for most classes as it incorporates the theory behind the word and symbol equations as well as information for a full practical session with analysis questions to finish. Your own risk assessment must be carried out for the practical.

A lesson focused on acid/metal reactions both word equations and symbol equations. Plenty of practice activities for students to have a go at. Includes a starter activity and a tricky final question.

Acid and metal theory and practical lesson for a mid level set. Make sure you do your own risk assessment 1st!

Preparing an insoluble salt - in this case making magnesium carbonate. Lesson includes method and analysis questions linked to the Pearson Edexcel textbook. \make sure you do your own risk assessment.

Solubility rules on one simple slide. Us e as part of another ppt or as a revision aid.

lesson focusing on solubility for GCSE level. Straightforward practical included. Results table, typical results included + practical instructions Please complete your own risk assessment

Full theory and practical for making an insoluble salt focused on the higher end grades 6-9. Some of the questions at the end link to the Pearson Combined Science text book (same questions will also be available in the GCSE Chemistry version of the book). Practical is straightforward, but make sure you do your own risk assessment for your class.

Calculating Mr - lots of relevant examples and some extra sheets you can print off to help students scaffold their work. feel free to share and adapt

Lovely little lesson introducing the skills and application of this fundamental chemistry topic. Includes a reminder about the periodic table and what all the "numbers mean"Aimed at the higher end so contains some tricky extension work for the students to have a go at. feel free to share this with colleagues.

A lovely lesson on calculating empirical formula (every students favourite topic!) - aimed at a mid range class with reasonable numeracy. Contains clear examples + activities within the presentation that can be printed off and completed. Also included is a blank template to help students structure there answers until they become more confident.

Revision lesson on the main themes in the chemical calculation topic. Use of the Pearson combined textbook would be handy as there are some page references that relate to it, but you could use whatever textbook you have and adapt it.

A structured worksheet for recapping the calculation section of combined science/chemistry using the bbc bitesize website as a source of info.

Lesson showing how to balance equations using mass data. Includes a starter question to!. Best to use with questions from the textbook you use or worksheets you have from your scheme of work. The power point focuses on the method of how to tackle these types of question.

An end of unit test aimed at the mid range grade target group, with mark scheme. Based on the chemical calculations unit that is in both combined and separate science qualifications

A tip top lesson on the theory behind the electrolysis of solutions for Edexcel GCSE Chemistry/Chem combined Science. Has question references to Pearson Edexcel textbook. This lesson will hopefully go some way to giving your evening back!

Core practical lesson - electrolysis of copper sulfate with copper electrodes, aimed at a lower ability set. Blank table of results and some further activities linked to the Pearson combined Science textbook if you have it.
