Why this works
Kids are born scientists who just need fuel
Every child asks why the sky is blue and where the puddle went. School science often has too little time to follow that curiosity: a topic flies by in two weeks and never returns. What isn't revisited, fades.
BrainBite keeps the questions coming. Short, vivid explanations, then questions that check real understanding, not just memory. Topics return in new contexts (the water cycle comes back in weather, then in states of matter), so knowledge connects instead of evaporating.
How science practice works with BrainBite
No worksheets, just lessons that move with your child.
Adaptive level
Too easy? The pace picks up. Too hard? Your child gets an in-between step first. Practice stays doable and fun.
Marie Curie helps
Stuck on a question? Mentor Marie Curie, an AI character inspired by the physicist and chemist, explains every step in plain language, with examples. As often as needed.
Calm learning
Everyone Mode removes every distraction: one exercise at a time, at your child's own pace. Great for every child, especially with ADHD or dyslexia.
Science practice by age
Every age has its own learning goals. Each age group has a practice page with all topics and example questions.
Ages 8–9
Discovering the world
- Living things and habitats
- Materials and their properties
- Simple experiments at home
Ages 9–10
How things work
- Forces, magnets and friction
- States of matter
- Food chains
Ages 10–11
Systems and cycles
- The human body
- Water cycle and weather
- Electricity and circuits
Ages 11–12
Test-ready science
- Earth and space
- Reading diagrams and data
- Mixed revision, test-style
Also practise: maths · spelling · reading · vocabulary · listening · speaking · writing · learn to read
Diagrams and data: how science tests ask questions
Science tests rarely ask 'what is friction?' Instead, they show a graph, a table or a diagram and ask what it means. BrainBite practises exactly that: reading a food chain, following a circuit, spotting the pattern in results. Understanding beats memorising.
Get startedCommon science mix-ups
Four classic trip-ups nearly every child (and let's be honest: every parent) stumbles over.
Do heavier things fall faster?
No. Without air resistance, a hammer and a feather land together. Astronauts proved it on the moon. Air, not weight, makes the difference.
Is the sun a planet?
No, it's a star. Planets orbit stars. The sun is our star; Earth is one of eight planets orbiting it.
Melting or dissolving?
Different things. Melting needs heat (ice → water). Dissolving needs a liquid (sugar disappears into tea, but it's still there).
Do plants eat soil?
No. Plants make their own food from sunlight, water and CO₂. Soil mostly provides water, minerals and something to hold on to.
Questions about science practice
What parents ask us most. Short answers, no fluff.
The science exercises are built for ages 8 to 12. BrainBite looks at what your child can already do, not just their age. Exercises adapt automatically.
15 minutes a day, 3 to 5 times a week, is plenty. Short, regular sessions work far better than one long session at the weekend.
Especially then. Exercises start exactly where your child is now. Every question they get right builds confidence, and AI mentor Marie Curie calmly explains each step.
Yes. The exercises follow the topics common to primary curricula, so your child recognises the material regardless of the textbook their school uses.
Yes. Children aged 10–12 practise mixed, test-style questions at a gentle pace, so test day feels familiar instead of scary. Short, regular practice beats last-minute cramming.
