Unit 5D: Changing state
Section 6: Drying and evaporation
|
|
Objectives |
| Children should learn: |
- to explain everyday examples of 'drying' in terms of factors affecting evaporation
|
Activities |
|
Outcomes |
|
Children: |
- Show pictures of appliances eg hairdryers, tumble dryers, rotary clothes line and ask children to explain how these help to make things 'dry' more quickly. Record explanations in writing eg in an advertisement for a particular sort of appliance.
|
|
- explain how to make things 'dry' more quickly using ideas about factors affecting evaporation eg the hairdryer warms the hair and blows the evaporated water away
|
|
Points to note |
It is important that children recognise that water evaporates at all temperatures and not just when it is warm. At low temperatures evaporation is very slow.
