1. LOADING… PLEASE WAIT… DURING THE Investigation AND FOR YOUR OWN SAFETY
NO CALLING OUT – IF YOU Need TO SAY SOMETHING, RAISE YOUR HAND
TUCK CHAIRS IN WHEN DOING THE PRACTICAL – NO SITTING DOWN
WEAR GOGGLES WHEN INSTRUCTED, UNTIL TOLD IT IS SAFE TO REMOVE THEM
DO NOT TOUCH THE LEAD METAL WITH YOUR FINGERS – USE THE TWEEZERS/TONGS PROVIDED
WASH YOUR HANDS AT THE END OF THE PRACTICAL
MR KHAN, ON BEHALF OF THE IMPOSSIBLE MISSIONS FORCE (IMF)

2. DISPLACEMENT REACTIONS
MISSION: IMPOSSIBLE
DISPLACEMENT REACTIONS

3. Your mission, should you choose to accept it:
displacement
a type of reaction where a metal is pushed out of its compound
least reactive
the substance that reacts less easily than the others
most reactive
the substance that reacts more readily than the others
reactivity series
a list of substances in order of reactivity, usually most reactive first
Your mission, should you choose to accept it:
Predict pairs of substances that react in displacement reactions
Use the reactivity series to explain displacement reactions

4. A REAL-LIFE DISPLACEMENT REACTION
a type of reaction where a metal is pushed out of its compound
least reactive
the substance that reacts less easily than the others
most reactive
the substance that reacts more readily than the others
reactivity series
a list of substances in order of reactivity, usually most reactive first

GROUPS OF THREE
Pupil 1: Collect goggles for partners
Pupil 2 and 3: Collect three INVESTIGATION sheets from me
Wear goggles before collecting equipment and chemicals.
Each person does two steps in the method. Work fast, you only have 10 minutes to complete the mission.
Once you have completed the sheet, show me and then collect the MISSION sheet from me. Choose ONE task to complete, then show it to me.

GROUPS OF THREE
Pupil 1: Collect goggles for partners
Pupil 2: Collect cards from me and lay them out on the table
Pupil 3: Collect three INVESTIGATION sheets from me.
Start your INVESTIGATION. Each person does two steps in the method.
Once you have completed the sheet, show me and then collect the MISSION sheet from me. Do as much as you can in the time available – we just have 10 minutes of experiment time, so hurry!
