Learning objectives
iKnow about the reactivity series.
iiKnow that a more reactive metal can displace a less reactive metal from its compounds.
Scientific enquiry
iiiDraw conclusions from data, interpreting patterns and using them to make predictions. (Framework YTO Sc1 9f)
ivPresent and interpret observations using charts. (Framework YTO Sc1 9e)
Suggested alternative starter activities (5–10 minutes)
Recap last lesson / Share learning objectives / Problem solving / Brainstorming / Capture interest
Quick quiz about displacement reactions. /
  • State the reactivity series for some metals.
  • Predict what displacement reactions will work using the reactivity series. (Sc1)
/ Pupils work out the relative reactivity of lead and zinc from a demonstration of displacement. / In groups, pupils discuss how to find out the reactivities of different metals. / Making an 'initial badge' by displacement.

Textbook F4 / i and ii / Teacher-led explanation and questioning OR Pupils work individually, in pairs or in small groups through the in-text questions and then onto the end-of-spread questions if time allows. / 20 min / R/G / G / R / S
Activity F4a Paper / i, ii, iii and iv / Using reactivity data Pupils use data from two experiments, one involving temperature change, to rank metals in order of reactivity. / 30 min /  / ()
Advance warning Tell pupils which metal they will be researching in Activity F5a. Ask them to carry out web searches to find information on its properties, uses and extraction.
Suggested alternative plenary activities (5–10 minutes)
Review learning / Sharing responses / Group feedback / Word game / Looking ahead
The class produces a list of key facts about metal reactivity. / Pupils compare the outcomes of Activity F4a. / Group work to make reactivity series display. / Play 'React or not?' card game. / Pupils discuss how to choose the right metal for the job.
Learning outcomes
Most pupils will … / Some pupils, making less progress will … / Some pupils, making more progress will …
  • use the data given to arrange the ten metals into a correct reactivity series
  • use this reactivity series to make predictions.
/
  • appreciate that metals can be arranged in order according to their reactivity.
/
  • appreciate the wider significance of the reactivity series and how it may be applied
  • be able to suggest experiments to deduce the reactivity of different metals.
