Lesson
Set out your lesson
“Life Changed Over Time 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
- Fossil photos or a printout of a trackway / skeleton
- Pencil and sticky notes
Extra for the adult
Worked example. Round footprints in a line suggest a walking animal, not a flyer.
Optional challenge. For Life Changed Over Time, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Life Changed Over Time, not mastery.

Check understanding
- State that living things have changed (evolved) over millions of years
- Describe how fossils form and what information they provide about the past
- Compare a fossil organism with a modern relative, noting similarities and differences
“Can your child explain that the animals and plants alive today are different from those that lived millions of years ago, and that we know this from fossils?”
