Say what you're studying, choose a tutor, then work through your homework step by step, take a quick quiz or call your tutor. This one is IGCSE Maths, and every subject works the same way.
Six teaching styles
One science question, six ways to teach it.
Each Science tutor teaches differently. Choose one to see how they would start, then pick the style that suits you. You can switch tutor mid-chat.
What’s the difference between a physical change and a chemical change?
Rohan · Concept explainer
A physical change changes how something looks, but it’s still the same stuff: melted ice is still water. A chemical change makes a new substance: burning paper leaves ash and gases that weren’t there before.
Can you think of an example of each from your kitchen?
How Rohan teaches
- Starts from what you already know
- Uses everyday examples and simple pictures in words
- Checks the idea has clicked before moving on
Pick Rohan when
a topic feels confusing, or you want to really understand it.
What’s the difference between a physical change and a chemical change?
Leila · Step by step
We’ll sort it out in two steps.
Step 1: when ice melts, is the water a new substance or the same one? Tell me what you think, then we’ll try step 2 with burning.
How Leila teaches
- Breaks every question into small steps
- Lets you try each step before showing the next
- Names the method so you can reuse it
Pick Leila when
you’re stuck on homework or a long, multi-step question.
What’s the difference between a physical change and a chemical change?
Victor · Exam coach
A common 2-mark question: “State one difference between a physical and a chemical change.” 1 mark: a chemical change makes a new substance and a physical change does not. 1 mark: a correct example.
Examiner tip: “new substance” is the phrase the mark scheme looks for.
How Victor teaches
- Works through past-paper style questions
- Explains command words and where the marks are
- Marks your answers the way an examiner would
Pick Victor when
an exam is coming and you want to pick up every mark you can.
What’s the difference between a physical change and a chemical change?
Ava · Quick revision
Quick recap. Physical: no new substance, often reversible, like melting or dissolving. Chemical: a new substance forms, often with fizzing, a colour change, heat or light.
Quick-fire: is rusting physical or chemical?
How Ava teaches
- Short recaps of the key points
- Memory hooks for facts and formulas
- Quick-fire recall questions
Pick Ava when
you’re short on time and want to refresh a topic quickly.

Tariq · Challenger
Dissolving sugar in tea: physical or chemical?
Now design an experiment that would prove your answer.
How Tariq teaches
- Asks questions that make you reason it out
- Raises the difficulty as you improve
- Shows the harder versions examiners use
Pick Tariq when
the basics feel easy and you’re aiming for top grades.
What’s the difference between a physical change and a chemical change?
Grace · Confidence builder
Lots of students find these two hard to tell apart at first.
Let’s start with ice: you’ve seen it melt and freeze again. Is it still water? That one clue does most of the work.
How Grace teaches
- Starts from the basics, with no judgement
- Celebrates every step forward
- Turns mistakes into learning, calmly
Pick Grace when
a subject makes you anxious, or you’ve fallen behind.
Topics students ask about
- Particles and states of matter
- Cells and living things
- Forces and energy
- Chemical reactions
- Electricity
- Earth and space
- Working scientifically
- Combined Science
