Weighing Evidence and Claims: a skill companion
Reusable sheets that grow one science skill: practise the skill in Weighing Evidence and Claims. Print once and slot into the science topics you already teach.
Start here
- Read the pairing map.
- Print scaffolds 1 and 2 when a lesson needs this skill.
- Cut out scaffold 3 once; reuse all year.
- Open the interactive unit for a worked example.
- Run the mini-lesson first if you want the skill on its own.
Slot the skill into your science lessons
Fold this skill into Year 7 Understanding units.

Can we test a question about weighing evidence and claims?
Which colour is the prettiest?
Does changing one variable keep a test fair?
Is a rainbow happy?
Should we record units with every number?
Can we ignore data that surprises us?
Does a table help us see a pattern?
Is louder always more scientific?
Can two groups compare results fairly?
Answer key is on the answers sheet.
Weighing Evidence and Claims clinic
Teach the skill on its own before folding it into a science topic. About 30 minutes.
We are learning to
- practise the skill in Weighing Evidence and Claims,
- use the pack scaffolds with a real science example,
Success criteria
- I can use one scaffold without copying a friend.
- I can explain the skill in one short sentence.

Answers and look-fors
Scaffold 3 cards
| Card | Fit? | Why |
|---|---|---|
| Can we test a question about weighing evidence and claims? | Yes | If we can watch or measure, yes. |
| Which colour is the prettiest? | No | Prettiest is an opinion. |
| Does changing one variable keep a test fair? | Yes | Fair tests change only one thing. |
| Is a rainbow happy? | No | Feelings are not measurable here. |
| Should we record units with every number? | Yes | Units make records clear. |
| Can we ignore data that surprises us? | No | Surprises need a second look. |
| Does a table help us see a pattern? | Yes | Tables organise counts. |
| Is louder always more scientific? | No | Evidence matters, not volume. |
| Can two groups compare results fairly? | Yes | If methods match, yes. |
