  1. Cool Condensation Aim: To understand and identify what is condensation. “Does it have anything to do with condensed milk?”

  2. Let’s Review: States of Matter

  3. Changing states

  4. Who Wants To Be A Millionaire? Changing state

  5. Question 1

  6. What are the three states of matter? A space, liquid and gas B space, line and gate C solid, liquid and gas D solid, line and gate

  7. What are the three states of matter? A space, liquid and gas B space, line and gate C solid, liquid and gas D solid, line and gate

  8. Question 2

  9. Which of these takes the shape of the container? A solids, liquids & gases B solids only C liquids only D gases only

  10. Which of these takes the shape of the container? A solids, liquids & gases B solids only C liquids only D gases only

  11. Question 3

  12. In which of these do particles move about the fastest? A solidsand liquids B solids C liquids D gases

  13. In which of these do particles move about the fastest? A solidsand liquids B solids C gases D liquids

  14. Question 4

  15. Which of these can be poured? A solids only B solids and liquids C liquids and gases D solids, liquids & gases

  16. Which of these can be poured? A solids only B solids and liquids C liquids and gases D solids, liquids & gases

  17. Question 5

  18. What caused the puddle of water? A water evaporating B steam condensing C the kettle leaking D water boiling

  19. What caused the puddle of water? A water evaporating B steam condensing C the kettle leaking D water boiling

  20. Question 6

  21. water steam ice X What process is occurring at X? A freezing B melting C evaporating D condensing

  22. water steam ice X What process is occurring at X? A freezing B melting C evaporating D condensing

  23. So what is condensation? • Condensation is: • A process – a change of state • Cooling process of gas to liquid • It is the opposite of evaporation

  24. Condensation in action! You teacher will now show you a cold can of drink, mirror and pair of glasses. See how the water droplets form on the objects. Breathe on the glasses and mirror! Challenge Question: Which object do you predict condensation will remain the longest?

  25. What is happening here?

  26. Condensation happens through flowers too! Watch carefully as your teacher prepares the flower. How do you think the water from the cylinder is able to reach the ziplock bag?

  27. Condensation Contained! While you wait for condensation to happen, get your CWB and draw a diagram with a paragraph explaining the process. - Title: Condensation • It’s time for you to create your own mini environment that will let you observe “condensation”. • Materials: • Container • Plastic cup • Cling film • Ice cubes • Hot water

  28. Invisible Water Vapour • So we have seen that when condensation happens, water droplets are formed. • Question: Where does this water even come from?? • Answer: The Air. • Water vapour (gas) is actually invisible to the human eye. • There are tiny water particles in the air. The more HUMID the environment, the more water particles there are!

  29. Water vapour (gas) is actually invisible to the human eye. There are tiny water particles in the air. The more HUMID the environment, the more water particles there are!

  30. Homework Find 3 examples of condensation that happens in the world. Draw a diagram and write a description explaining why there is condensation. (e.g. water droplets on a cold glass, wet walls and floors during cold & humid days, etc)
