The Periodic Table
Describe the organisation of the periodic table into periods and groups, explain the contribution of Mendeleev, and use the table to identify metals, non-metals, and predict patterns in reactivity
Lesson
Set out your lesson
“The Periodic Table means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.”
Bring to the table
- Two everyday materials (e.g. ice cube / warm water / salt / spoon)
- Clear cup and paper for notes
Extra for the adult
Worked example. Ice melts in the warm cup: solid → liquid. Heat caused the change.
Optional challenge. For The Periodic Table, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples The Periodic Table, not mastery.

Check understanding
- Explains why the periodic table is arranged into periods (rows) and groups (columns)
- States that elements in the same group have similar chemical properties
- Locates metals, non-metals, and metalloids in the periodic table
- Explains how Mendeleev ordered elements by atomic weight and predicted missing elements
“If your child was looking at a periodic table, could they explain why elements in the same column tend to behave similarly — and say what Mendeleev did that made it so useful to chemists?”
