Lesson Title: Today we are learning about
What is latent heat?

Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding

Success Criteria:	You will show your learning by...
Students should be able to recognise/draw simple diagrams to model the difference between solids, liquids and gases. The particle model can be used to explain ? the different states of matter ? differences in density. Students should be able to explain the differences in density between the different states of matter in terms of the arrangement of atoms or molecules. If a change of state happens the energy needed for a substance to change state is called latent heat. When a change of state occurs, the energy supplied changes the energy stored (internal energy) but not the temperature. Students should be able to describe how, when substances change state (melt, freeze, boil, evaporate, condense or sublimate), mass is conserved. The specific latent heat of a substance is the amount of energy required to change the state of one kilogram of the substance with no change in temperature. Changes of state are physical changes which differ from chemical changes because the material recovers its original properties if the change is reversed.

AFL/Key Questions:

Draw a diagram pf particle arrangement for a solid; a liquid and a gas.
Solid: particles in a pattern and close together. Liquid: particles not in a pattern and close together. Gas: particles not in a pattern and far apart.
What two things can the particle model be used to explain?
The particle model can be used to explain the different states of matter differences in density.
In terms of particles, explain why ther are differences in density between the different states of matter.
Gas are significantly less dense than liquids because the same number of es are spread out over a significantly greater particlvolume in a liquid. Liquids are less dense than liquids because the same number of particles are spread out of a slightly greater volume than in a solid.
What is meant by the latent heat of a substance?
Latent heat is the amount of energy needed for a substance to change state.
What happens to the temperature when a change of state occurs?
When a change of state occurs, the energy supplied changes the energy stored (internal energy) but not the temperature.
What happens to the mass of a substance as it changes state?
The mass of the substance is unchanged as it changes state due to the umber of particles remaining unchanged.
What is the specific latent heat of a substance?
The specific latent heat of a substance is the amount of energy required to change the state of one kilogram of the substance with no change in temperature.
How do changes of state differ from chemical changes?
Changes of state are physical changes which differ from chemical changes because the material recovers its original properties if the change is reversed.

Starter Activity	Differentiation and Challenge question/task
Students to copy and complete the keywords. Teacher reveals missing letters; Students correct mistakes; Discuss the scientific meanings of the words. Students to write down the definitions of the most important / new keywords. Discuss the 'Memory Anchor'. What does it show? How does it relate to the what we are learning about today (title)?
