Getting your head around dense scientific terminology requires focused, individual guidance. That’s the work a good Year 7 science tutor in Sydney does: finding the step that trips them up and fixing it together.
The NSW Science 7–10 Syllabus (2023) began in schools in 2026, so this year’s Year 7s are learning it from the start. Running through every topic is Working scientifically: observing, questioning, planning and running investigations, and analysing data.
The words and variables at the heart of Year 7 science
Two things cost Year 7s the most marks in science. The first is language: many science words have precise meanings that differ from everyday use, and using the everyday meaning in an answer loses marks.
| Word | Everyday meaning | Scientific meaning |
|---|---|---|
| Weight | How heavy something is, in kilograms | The force of gravity on an object, measured in newtons |
| Mass | Often used to mean weight | The amount of matter in an object, measured in kilograms |
| Theory | A guess | A well-tested explanation supported by a lot of evidence |
| Dissolve | Often confused with melt | A substance spreading evenly through a liquid to form a solution |
| Reliable | Trustworthy | Gives consistent results when an experiment is repeated |
| Accurate | Correct | Close to the true value |
The second is the scientific method itself, especially the three kinds of variables in an experiment. Here they are for one simple investigation: does water temperature change how fast sugar dissolves?
| Variable | What it means | In this experiment |
|---|---|---|
| Independent | The one thing you deliberately change | Water temperature |
| Dependent | What you measure to see the effect | Time for the sugar to dissolve |
| Controlled | Everything kept the same so the test is fair | Amount of sugar, volume of water, type of sugar, stirring |
A memory hook: you change the independent, you measure the dependent, and you control everything else. That one rule is worth teaching directly. In a US classroom study, explicit teaching of “change one thing and keep everything else the same” lifted primary students’ ability to design fair experiments from 30% before instruction to 96% after.
How we check real understanding in an online session
Every student starts with a free 30-minute intro session, where the tutor learns how they’re feeling about school, the marks they’ve been getting and want to get, and the rhythm of their week.
For science, the tutor also checks foundational principles. They take whatever topic your child is up to in class and question them back and forth, out loud, until it’s clear whether they understand the idea or only the words.
What that back-and-forth sounds like
| Who | What they say |
|---|---|
| Tutor | What happens to sugar when it dissolves in water? |
| Student | It melts. |
| Tutor | If it melted, what would you see if you heated sugar on its own? |
| Student | It would turn into a liquid. So it’s different in water? |
| Tutor | Right. What do you think is happening to the sugar particles in the water? |
| Student | They’re spreading out between the water particles. |
That last answer is the one we’re after: the student has moved from a familiar word to the scientific idea underneath it. Sessions run on Google Meet with a shared digital whiteboard, and the right words and explanations go into your child’s notes in the shared Google Doc.
How to lay out your scientific answers step by step
“Explain” questions are where scientific language and reasoning come together. NESA’s glossary defines explain as relating cause and effect and providing why or how, so a one-word reason won’t earn the marks.
Four steps for any “explain” answer
- Use the scientific term for what’s happening.
- Say what happens.
- Say why it happens, using the science: particles, forces, cells.
- Link back to the question in the last sentence.
Explain why sugar dissolves faster in hot water.
| Weak answer | Strong answer |
|---|---|
| Because it’s hot. | In hot water, the water particles move faster and collide with the sugar more often and with more energy. This helps the sugar particles break away and spread through the water more quickly, so the sugar dissolves faster at a higher temperature. |
The strong answer uses the right terms, gives a cause and an effect, and ends by answering the question directly.
