Quantitative chemistry

This resource features three versions of a worksheet on quantitative chemistry: scaffolded, partially scaffolded and unscaffolded. Use the worksheets to identify learners’ knowledge gaps and misconceptions after teaching or before revisiting these topics. Find out more about how to use this resource or download the worksheets now.

Curriculum topics

The quantitative chemistry worksheets cover the following topics:

• atoms and molecules
• elements and compounds
• reactants and products in a chemical equation
• simple chemical formula
• law of conservation of mass
• writing simple word equations
• writing simple balanced symbol equations
• calculating the mass of a reactant or product in a chemical reaction given all other reacting masses. 

If learners successfully answer questions on these topics, they can attempt the extension questions. These cover:

• using the periodic table to find the relative atomic masses of named elements
• calculating relative formula mass.

Independent learning and metacognition

The ‘What do I understand?’ page is common to all worksheets. Learners are encouraged to develop independent learning skills and can use their reflection as a guide for revision. The feedback will also help you to identify areas where a whole class needs attention.

Answers

The teacher guidance provides model answers for each worksheet, plus guidance on learners’ common misconceptions. Learners can use the model answers to self- or peer assess.
