LET’S TRY ONE
A plant was 4 cm tall on Monday and 7 cm on Friday. What does this show?
It grew 3 cm taller.
7 − 4 = 3 cm of height increase.
Learning steps & teaching tips
Use a plant observation log to identify a measured change.
- Separate what a log records from explanations that still need testing.
- Work through the example. Explain how its evidence supports the answer.
- Try a new question; use the explanation to check your thinking.
Try it together
Make one new example with a partner. Identify the evidence for your answer before checking it together.
