What it is about

Connect a growth condition to a trait using supplied evidence without overclaiming causation.

Grade 3 · 8–9 years · 30 challenges

Before you begin

• K–2 observations of materials, habitats, life structures and Earth changes.

What the class will do

1. Sort into groups · 6 challenges

   Check what the record supports

   Use this question’s supplied plant record. Sort careful observations and explanations separately from claims the record does not establish.

2. Choose and explain · 24 challenges

   Explain the result and its limits

   Compare conditions, starting points and outcomes. Discuss the evidence before choosing an explanation; do not invent a missing result.

Using it in class

Everyone proposes a claim and points to the supplied records before a rotating representative acts. Illustrative plant records require no real experiment or withholding care. Keep unknown results unknown. Plan 30–45 minutes for 30, or choose a block/short round.

Give everyone time to think and discuss before one pupil acts at the board. The class explains and confirms together; hints and explanations stay until you move on.

Use an up-to-date browser on a computer connected to a whiteboard or shared display. Touch, mouse and keyboard; optional audio and reduced motion. No pupil accounts or personal devices.

Choose from 5 challenges up to the full activity. Discussion determines the duration: you set the pace.
