During the activity video clips of
displacement reactions are shown alongside
an animation of a Sumo wrestling contest.
If displacement occurs the defeated
Sumo wrestler is pushed out of the
ring. Some clips show there is no
reaction, in which case neither wrestler
is pushed out of the ring.
Students accumulate points by betting
correctly on the results of the displacement
reactions. They can revise an incorrect
bet after watching the video clip,
although their points score will be
After each match pupils rearrange
the metals on-screen. When they are
ready they submit their order of reactivity.
They lose points if they submit an
incorrect reactivity series, and must
return to the game to check their
conclusions. They may re-submit their
table as many times as necessary.
At the end they get a certificate
print-out to show their points scored
and the final correct table.
Print out the two pupil's sheets.
Pupils will need these for the activity.
Students are shown an on screen demonstration
of the interactive activity for the
reaction between copper sulphate solution
and iron metal. The demonstration
takes them through each step of the
- watching the video clip
- placing a bet
- watching the video clip plus animation
- the eventual result of this match
Pupils then choose a reaction to
bet on and run the activity themselves.
After each reaction pupils record
the results on their first sheet.
They can be extended to writing a
word equation OR a symbol equation
on the second sheet.
After watching all the displacement
reactions, pupils submit their final
reactivity series for checking.
