Settling Down & register
Write down L.O
Starter/ Hook
Diffusion in 3 states of matter
Balloon Magic Trick
Write in books what they think is happening using the
particle
model
Pot Perm:Try and explain what is happening in the water
Ice Cube:
Why did nothing happen?
Role Play:
Outside (if weather is good). Half the students wear white
lab
coats. Get class to model diffusion in a gas/liquid/solid
Write down definition and explanation of diffusion in book
using
the particle model
Class discussion
Explain how diffusion rates are affected by temperature etc.
using particle model in books
Take Register
Demo: Balloon Magic Trick
Move class round table. Set
up Balloon Magic Trick. Passbox around ask them to
suggest what is happening. If
the balloon is closed how can
the smell get out?
Get suggestions
Class expt: Pot Perm
Move questioning towards two
types of particles expanding
out
Class expt: Ice Cube
Take outside for role play
Tell class this process in the
L.O is called diffusion
Which states of matter did
we look at?
Why is there no diffusion in a
solid?
Why is diffusion faster in a
gas?
Class expt: Pot Perm in warm
water
Point out L.O
Ask what can affect the
movement of these particles?
Explain Balloon answer

Have we hit all our L.Os?
Remind students to use level
ladders and L.O and to answer
the question using the
particle model is L5+
