| When is it happening | Term 2 Year 7 | ||
| What will students learn | Students need to be able to identify elements from physical and chemical properties. They need to know the products of metals reacting with acids. That metals can be arranged as a reactivity series. Know what oxidation is. Describe oxidation, displacement and metal- acid reactions with a word and symbol equation. Use particle diagrams to represent oxidation, displacement and metal- acid reactions. Know what a base is. Know how to carry out a neutralisation reaction and predict the salts formed. Know the hazards of acids and alkalis. Know the pH scale, what indicators are and be able to identify the best indicator. | ||
| Key Knowledge that students should know at the end of 'Topic' | This is the knowledge that students will meet for the first time in this topic |
Properties of metals and non- metals. Metals react with acids to produce salts + hydrogen. The products of acid reactions with metals and bases. The reactivity series. Oxidation and displacement reactions. The chemical symbols for acids. Writing word and symbol equations for metal- acid reactions, oxidation and displacement. The hazards of alkalis. The pH scale and what it shows. Choosing the correct indicators and how to use them. |
|
| This is knowledge that students may have met before but will need to deepen their understanding | Students should have a basic understanding of the hazards of acids. They should be able to explain that new materials are made in a chemical reaction. | ||
| Key Skills that students should be able to demonstrate at the end of 'Topic' | This is the skills that students will meet for the first time in this topic | Writing word and symbol equations. Drawing particle diagrams to represent oxidation, displacement and metal-acid reactions. The safe handling of acids and alkalis. Practically carrying out acid reactions, including neutralisation. Practically using indicators to inform of pH. Practically using the pH scale. | |
| This is skills that students may have met before but will need to develop | Students will not have come across the skills required for this topic in KS2 | ||
