Children: |
- Provide groups of pupils with a set of statements,
eg
- neon has only one sort of atom
- there are more non-elements than elements
- an apple is an element
- very few elements are liquids at room temperature
- all gases are elements
- water is an element: it is made of hydrogen and oxygen atoms
and ask them to agree whether they are true of false.
- Discuss pupils' answers with them and agree a list of key points about atoms and elements. Provide pupils with their own copy of the periodic table on which they can mark particular things,eg metals/non-metals.
|
|
- classify materials as elements and non-elements
- explain their classification
- identify that elements are made from atoms of one kind
- make some generalisations about elements
|
|
Points to note |
- Periodic tables used in other countries can be used to show pupils that the symbols for the elements are the same. These may be found on the internet.
