Form 1: Simple Chemical Reactions
Note: This document is to be used as a guide. The purpose is to ensure that students are prepared for the standardised End of Unit Test. Feel free you use your own resources in lessons.
Lesson 1: Is there a reaction?
LO: Revisit safety in the lab Skill: carry out different reactions, and write observations
Starter:How do you know that a reaction s occurring?
Main activities: Students meet the LOs Discuss the differences between physical & chemical reactions Complete worksheets in class e.g. exploring science 7Fa3-5, or for
homework
Possible practical activities:Exploring Science 7Fa/1, 7Fa/2
Plenary:What have I learnt today? Recap of LOs
Lesson 2: Acids & Metals
LO: Revisit safety in the lab To be able to identify reactions in which Hydrogen is produced Skill: carry out different reactions of metals with acid
Starter:What is an acid?
Main activities: Students meet the LOs Discuss the differences between physical & chemical reactions Complete e.g. practical that involve reacting e.g. Zn, Cu, Fe, Mg with HCl
Other worksheets:Exploring science 7Fb6, 7Fc6, 7Fc5, Catalyst unit 7F
Plenary:What have I learnt today? Recap of LOs
Lesson 3: Burning metals in Oxygen
LO: To write the word equation for different metals reacting in oxygen Skill: to burn Copper, Iron, and Aluminium in Oxygen
Starter:Demo: Burning Magnesium in oxygen
Main activities: Students meet the LOs Burn different metals in oxygen Exploring science 7Fd1-2
Plenary:What have I learnt today? Recap of LOs
Lesson 4: Modeling a fire
LO: Define combustion Describe & Explain how to put out a fire Write equations for complete & incomplete combustion
Starter:What is needed to start a fire?
Main activities: Go through the fire triangle & different types of fire extinguishers Produce a fire safety poster
Plenary:How many songs can you think of that have a fire related theme to it?What have I learnt today? Recap of LOs
Lesson 5: Comparing Fuels
LO: To investigate which of two fuels produce the most energy per gram on burning
Starter:What are fuels?
Main activities: Using a spirit burner, burn two fuels e.g. propanone and ethanol
Plenary: Discussion of results Which harmful products are produced when we burn fuels?
Lesson 6: Displacement Reaction
LO: To investigate which of two fuels produce the most energy per gram on burning
Starter:What do you think it means if I say “Pancho displaced John from a relationship with Maria?”
Main activities:
Chem4U pg84You will use a spotting title to carry out the following potential reactions. Add a small piece of metal and
relevant solutions as directed.
Plenary: Discussion of results Complete the displacement boardworks worksheet
Lesson 7: Rust
LO: To describe and explain what rust isTo investigate how rust can be prevented
Starter: What is rust?
Incre
Potassium
Sodium
Calcium
Magnesium
Aluminium
You might need to get some results off another group to finish the results table.Results•Which results
showed a
Main activities: To investigate how rust can be prevented Complete worksheets relating to rust
Plenary:Revisit the LOs
Lesson 8: Acids & Carbonates
LO: To list where carbonates are foundTo investigate what happens when a carbonate reacts with acid
Starter:Students identify limestone from the selection of rocks n the table (between 3 or 4 students)
Main activities: Marble chip experiment-reacting marble chips or calcium carbonate with
hydrochloric acid. Compare lager to small chips.
Highlight that carbon dioxide gas is produced, not hydrogen
Plenary:Revisit the LOs
Lesson 9: Making Gases
LO: To make e.g. carbon dioxide, hydrogen, and oxygen experimentally, and test for them
Starter:What is the difference between carbon dioxide, hydrogen, and oxygen?
Main activities:Complete various experiments in which different gases are produced
Plenary:Revisit the LOs, and discuss results
Lesson 9: Making Gases
LO: To make e.g. carbon dioxide, hydrogen, and oxygen experimentally, and test for them
Starter:What is the difference between carbon dioxide, hydrogen, and oxygen?
Main activities:Complete various experiments in which different gases are produced
Plenary:Revisit the LOs, and discuss results
Lesson 10&11: Other Chemical reactions & Food Spoilage
LO: Outline different examples of chemical reactions used at home or in industry
Starter:Name the process/chemical reaction that takes places at meal times
Main activities:Complete a table similar to the one below:
After discussing how food spoilage can be presented, students produce a song outlining this.
Plenary:Revisit the LOs, and play recordings
