What’s that smell?

Learning Outcomes ALL will be able to state an example of diffusion (level 4) MOST will be able to describe what is meant by diffusion (level 5) SOME will be able to explain why diffusion happens more slowly in liquids than in gases (level 5-6)

Literacy in Science Key Words: particles diffusion

Smelly gases! When you spray perfume, you give off smells which spread through the air…

Particles DIFFUSION means that the ‘perfume’ particles spread through a room on their own

Why do you think diffusion can happen in liquids? Diffusion in Liquids Why do you think diffusion can happen in liquids?

Any sensible answer - Level 4 Model Answers Q1. Give an everyday example of diffusion. ‘An everyday example of diffusion is the smell of cooking/ the smell of aftershave…’ Any sensible answer - Level 4

Model Answers Q2. When you spray Lynx, what happens to the particles? a. They spread out (Level 4-5)

Model Answers Q3. Describe what is meant by diffusion. ‘Spreading of particles’- Level 4 ‘Particles spreading out without anything moving them’- Level 5 If they have discussed particle STRUCTURE- Level 6

Model Answers Q4. Which is faster, diffusion of body spray particles or diffusion of sugar particles in tea? Explain why. ‘Diffusion of particles of body spray is faster. Particles in a gas move faster than those in liquids and there is more space between gas particles for new particles to move into’- Level 5-6

Model Answers DIFFUSION NOT DIFFUSION OPENED JAR OF COFFEE STIRRING SUGAR IN TEA BARBEQUE + BREEZE DIRTY NAPPY

Model Answers Q5. Which of these are examples of diffusion? (level 5-6) a. diffusion

Model Answers Q5. Which of these are examples of diffusion? (level 5-6) b. not diffusion

Model Answers Q5. Which of these are examples of diffusion? (level 5-6) c. not diffusion
