Lesson Title: Reacting metals

NC Ref: 

Objectives:    

MK - metals will tarnish in the air. oxygen is the gas with which they react. gold does not react with oxygen. some metals react with water
SK - some metals are more reactive than others. reacting with oxygen forms oxides, hydrogen gas is formed when some metals react with water. mass increases when metals react with oxygen.
CK - Predicting reactions based on reactivity. oxide layers affect reactivity.

Lesson outline: Horsforth Commentary

Starter activities: Reaction with water. Have seen how metals react with acid.  But some metals are so reactive that they react with water. Pupils could attempt to find the gas formed when calcium reacts with water/ or show this as a demo.

Show the reactive metals and prove they are metals by etching away the oxide layer. these metals are kept under oil so that they cannot react with oxygen or water.

Demo the reactive metals water. highlight the fact that an alkali is formed by using UI in trough.  Pupils only need to know up to potassium and other more reactive metals will be shown at Key stage 4.
 

Possible extension lesson. React magnesium with steam to show that temperature has an affect on the reaction. page 77 in exp sci 7 fits with this.
Plenary:

Write up word equations/ metal + water --> metal hydroxide + hydrogen.

 react magensium with steam
 

Timings:

Homework Suggestion: why does magnesium react with steam not cold water?

or worksheet Fa/4 or sheet Fa/5

Resources: . calcium tweezers, spatula, scalpel, lithium, sodium, potassium.

Lesson 2 

Unit Title:  Reactivity series
Caretaker: pmc

Unit No   
 

Lesson Title: Reactivity series of metals

NC Ref: 

Objectives:    

MK - some metals react with acids to make a gas. names of some reactive metals
SK - hydrogen is given off when metals react with acids, how to describe reactivity series of metals with acids, word equations.
CK - symbol equations.

Lesson outline: Horsforth Commentary

Starter activity: Using periodic table, do first to find exercise. eg. the symbol for iron,metal with symbol K etc.

Reminder of what happens when metals react with acids. salt + hydrogen
 
Main course: Pupils react different metals in 1M solution of hydrochloric acid. These are then placed in order of reactivity. calcium, magnesium, zinc, iron, lead, copper. sheet Fb/1

or could do sheet Fd/2

Plenary: card sorting activity sheet Fb/3

Unit No   
 

Lesson Title: Metal reactions with oxygen

NC Ref: 

Objectives:    

MK - some metals react with acids to make a gas. names of some reactive metals
SK - hydrogen is given off when metals react with acids, how to describe reactivity series of metals with acids, word equations.
CK - symbol equations.
 

Lesson outline: Horsforth Commentary

Main course: These metals tarnish (only iron rusts) because they react with oxygen. Metal + oxygen --> metal oxide.

Show the rusty nail. it has reacted with oxygen but slowly. We can speed the reaction up by using heat.

Main course: Demonstrate to pupils a variety of metals with oxygen by using deflagrating spoons and lowering into oxygen. could also use a drinking straw to blow small amounts of powder into the flame. This shows that aluminium is actually reactive!

Plenary: sheet Fb/ 4
 

Timings:

Homework Suggestion: key homework!!
 

Resources: gold (jewellery labelled gold), rusty nail, an old tarnished copper coin, tarnished magnesiumgas jars full of oxygen, drinking straws (dry and clean) metals in powdered and foil form, copper, aluminium, magnesium, zinc, iron, lithium and sodium (Li and Na just as normal!)
 

Lesson 4 

Unit Title:  Reactivity series
Caretaker: PMC

Unit No   
 

Lesson Title: 

NC Ref: 

Objectives:    

MK - some metals can react with compounds of other metals, signs of a chemical reaction
SK - a more reactive metal will displace a less reactive one. be able to predict if a displacement reaction will happen.
CK - symbol equations

Lesson outline: Horsforth Commentary

Starter activity: demo thermit. proof of iron production by use of magnet. This reaction is used to repair railway lines. Don't have to replace the whole rail, just shove in some new iron.
 
Main course: Go through the idea of a reactive metal displacing a less reactive one. This can be done in many ways, eg. sexy metals, who will get the oxide? Boxing etc.

Pupils conduct the practical on metals and their solutions. This works well in the spotting tiles with small amounts.

Plenary:
pupils could guess what would happen if they used calcium or silver in the list.

Timings:

Homework Suggestion: 
 

Resources: iron oxide powder, magnesium powder and ribbon, tin dish full of sand, copper sulphate, iron III sulphate, lead nitrate, magnesium sulphate, zinc sulphate, all 0.4M.      magnesium ribbon, zinc granules, lead , iron nail/wool,copper foil.
