Icing sugar blown from a funnel attached to a rubber tube, upwards past a Bunsen burner flame, combusts to produce a shocking and beautiful display.
Yeast experiment
Fungi experiment looking at the affect of temperature on growth using a balloon, 10% yeast,10% glucose, water bath, ice, and room temperature. Result in 1 hour only 2 balloons blew up in the water bath.
Rainbow Fizz
Chemistry practical showing neutralisation.
Screaming babies
Involves putting a jelly baby into molten potassium chlorate. The reaction shows the oxidation of the sugar in the jelly baby. Sometimes a high pitched screaming noise can be heard during the reaction.
Screaming baby (jelly) EVEN BIGGER!!!
Terminal Velocity/drag physics practical
you can have one student with a timer say ‘now’ every second and another student mark on the pipe with a whiteboard marker where the ball is (then you can see the intervals become more uniform, reaching terminal velocity) or the opposite
No leak bag
Sodium Ethanoate
Lycopodium powder flame
Lycopodium powder flame – shows the chemical energy stored in a small amount of lycopodium powder, also shows that surface area increases rate of reaction
