Pure Substances and Mixtures: a full term of science
Ten ready-to-teach lessons for Year 7 Chemical sciences. Print this pack and the term is prepared: every lesson has a plan, talk prompts, a student worksheet, cards or tickets, and answers.
Start here: five minutes to Monday
- Skim the term at a glance on the next page.
- Print the lesson you need (plan, worksheet, cards).
- Gather everyday items under You need on the plan.
- Open the free interactive unit on your board.
- Teach from the plan: timings, prompts and answers are on one page.
No science background needed
Written for the busy generalist teacher. Plain words, common muddles, and model answers are on every plan. Safety: no open flames or boiling water unless an adult controls a warm-water step named on the plan.

Assessment
- Every plan ends with answers and look-fors.
- The assessment kit near the front has a rubric and class checklist.
- Lesson 10 is the summative check and model task.
Materials for the whole term

Assessment without extra work
Lesson plans carry look-fors. Lesson 10 is summative. Use this sheet for ongoing notes.
The three levels
| Idea | Working towards | At standard | Beyond |
|---|---|---|---|
| Big idea | names an example with help | explains the unit idea in Year 4 words | applies the idea to a new example |
| Evidence | guess only | links a claim to something observed or measured | compares two pieces of evidence |
| Science words | everyday words only | uses unit words correctly | explains a word to a partner |
| Inquiry habit | follows steps with support | plans or records with the scaffolds | improves a plan after a first try |
Class observation checklist
| Name | Idea | Evidence | Words |

Dear families
This term in science, Year 7 explores pure substances and mixtures. We use observation, simple tests and clear science words. Ask: What did you notice today? What evidence did you use?
Try this at home
- Talk about a pattern you both notice outdoors or in the kitchen.
- Ask for one science word from the week and use it in a sentence.
- Draw a simple diagram of something they investigated.
Warm regards,
The Year 7 team

Pure or mixed?
Children explore “Pure or mixed?” with talk, the board picture, and a short paper task. About 60 minutes, or two 30-minute sessions.
We are learning to
- explain the idea behind pure or mixed? in Year 7 words,
- use the board picture to check our thinking,
- record an example with evidence.
Success criteria
- I can show one clear example of today’s idea.
- I can say the idea in a short science sentence.
You need
- interactive unit open on “Pure or mixed?” when available,
- worksheet (next sheet), one per child,
- optional cut-out cards or exit tickets (third sheet).
Lesson flow (about 60 minutes)
| 10 min | Hook Quick oral examples linked to the unit story. Ask: “What do you already know that might help today?” |
| 15 min | On the board Open “Pure or mixed?”. Step the controls while children predict. Ask: “What changed? What stayed the same?” |
| 20 min | Worksheet Children complete the sheet. Circulate for the muddles listed below. |
| 15 min | Share and exit Two children share. Class finishes the exit sentence. Ask: “In one sentence, what was today’s idea?” |
Split point: after On the board. Session B is worksheet and share.
Watch for
- Skipping the board and only copying answers -- bring them back to the picture.
- Correct answer with no explanation -- ask how do you know?
Make it easier, make it bigger
- Easier: complete the first two worksheet items together.
- Bigger: invent one new example for a partner to solve.
Answers and look-fors
- Meeting the idea sounds like a clear sentence about pure or mixed?.
- Drawings or numbers match the board story.
