Displacement challenge
Which metal displaces which?
Metal on the left. Liquid along the top.
Displaces (reaction happens)
No reaction
A metal only pushes out the metals below it.
Put them in order
Most reactive at the top.
Drag or tap a card

Reactivity ladderShows the series down the side of the screen, highlighting the two metals in the current test.
Outline the objectsDraws a dark edge round each sample so it stands out from the bench behind it.
Procedure
Ask me to predictAsks what will happen at the moment the metal goes into the beaker, not before the drag.
Shuffle the benchSets the metals and the solution buttons out in a random order, so their position never gives the series away. Turn it off to keep them in reactivity order.
Show ionic equationsAdds the higher tier ionic equation to the result card.
Buttons onlyAdds a button for every metal, so nothing has to be dragged in the 3D scene.
Show the answer buttonOn the order task. Turn it off so pupils commit to an order first.
