Year 7 science: turn new vocabulary into clear explanations this September
Starting Year 7 science brings new rooms, equipment and expectations. It also brings words that sound familiar but have a precise scientific meaning. A pupil might understand a demonstration yet struggle to explain it because terms such as particle, substance and variable are still new.
This retrospective September topic guide focuses on that early secondary adjustment. The aim is not to learn a whole textbook ahead of school. It is to make the vocabulary from current lessons usable, through brief practice that leaves room for settling in.
1. Choose three words from this week's lessons
Ask your child which science topic they are studying, then choose three terms their teacher has introduced. Use the school glossary or class definitions to check accuracy. Schools teach topics in different orders, so follow their lessons rather than a generic September list.
For each word, ask your child to produce a simple explanation and an example. If the word is conductor, they could say: “A material that allows electric current to pass through it easily. Copper is an example.” Specify electrical conduction here, since pupils will also encounter thermal conduction.
Keep the list small. Three terms your child can explain accurately are more useful than fifteen definitions they cannot yet apply.
2. Separate everyday meanings from scientific meanings
Some confusion comes from words pupils already know. In everyday conversation, a solution might mean an answer to a problem. In science, a solution is a mixture formed when a substance dissolves in a solvent.
Try a quick sorting task with these sentences:
- “We found a solution to the missing homework problem.”
- “Stirring salt into water produced a solution.”
Ask which sentence uses the scientific meaning and why. Then invite your child to create their own example.
Follow this with a distinction between nearby terms. For dissolving, ask: “Has the salt disappeared, or is it still present in the water?” A useful explanation is that the salt remains present even though individual pieces are no longer visible. Do not use tasting as a test, particularly with laboratory materials.
3. Build an explanation around one observation
Knowing a definition is only the starting point. Pupils also need to connect vocabulary to what they observe.
Use a familiar example: a puddle becoming smaller on a dry day. Ask your child to explain it using evaporation. If they say only “the water disappears”, prompt them with: “What happens to the liquid water?”
A stronger answer is: “Liquid water changes into water vapour and mixes with the surrounding air.” If particle ideas have already been taught, ask them to add that some particles escape from the liquid surface.
Keep prompts specific rather than supplying the whole answer. “Where does the water go?” helps your child identify the missing idea without turning the task into copying an adult's sentence.
4. Check recall briefly and agree when to ask for help
Twice a week, spend five minutes asking your child to explain the three chosen words without looking at their definitions. Change the example so they have to think: after discussing salt water, ask whether sugar dissolved in water also forms a solution.
Note whether each term is secure, partly understood or confusing. Return to confusing words with a different example, not a longer list.
If the same misunderstanding persists, help your child prepare a specific teacher question: “I understand that salt dissolves, but how is that different from melting?”
