LO- Show understanding by explaining a chemical reaction using the particle model. Success criteriaLevel 6 – Identify strengths & weaknesses of other models Level 5 – explain the particle model of a mixture using diagrams and scientific words in paragraphsLevel 4 – to use the particle model to describe a gas using scientific words in sentences
By the end of the lesson I will be able to:
Using particle model
Particle model
• Using your bits of magnesium, iron & oxygen - model what the particles would look like out of playdoh
• Hint think about whether they are elements or not & whether they are solid, liquids & gas
Particle model
• Now that you have made your reactants think about how the products would be formed and show this using your Playdoh.
Writing word equations
• Magnesium + oxygen = _____ _____
• reactant + reactant products
• Iron + oxygen = _____ _____
• Copper + Oxygen = ________ ______
Writing a word equation
• Abbey reacted silver metal with oxygen in the air. Black silver oxide was formed
• Write a word equation showing the reactants and product formed
Learning objective : To write an explanation that demonstrates scientific understanding of the reaction of iron with sulphur
Success Criteria Level 6 – Explain using a model in logical paragraphs what happens when a metal reacts with an acid using symbol equations where possible Level 5 – Explain using a model what happens when a metal is added to an acid using word equations where possibleLevel 4 – Describe using sentence what happens when a metal is added to an acid Level 3 – Recall what happens when a metal reacts with an acid
