Evaluating Methods and Claims: a skill companion

Reusable sheets that grow one science skill: practise the skill in Evaluating Methods and Claims. Print once and slot into the science topics you already teach.

AC9S8I06

analyse methods, conclusions and claims for assumptions, possible sources of error, conflicting evidence and unanswered questions

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.

On the board

On-screen moves include: “Sound conclusion, or an over-claim?”, “Spot the reading that exposes a method flaw”, “How should the method be fixed?”.

Scaffold 3 · Sort cardsReuse all year

Sort the cards

Cut out. Sort into yes / no piles and justify why.

Can we test a question about evaluating methods 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.

Mini-lesson · Teacher planAbout 30 minutes

Evaluating Methods 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 Evaluating Methods 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.

Lesson flow

5 min	Hook Ask: “What skill are we practising today?”
10 min	Card sort Tables sort scaffold 3 cards.
10 min	Write Scaffold 1 then scaffold 2.
5 min	Exit Ask: “Finish: Today I learned to...”

On the board

Use “Sound conclusion, or an over-claim?” as the lead picture.

Answers · For the teacherModel responses

Answers and look-fors

Scaffold 3 cards

Card	Fit?	Why
Can we test a question about evaluating methods 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.
