Daily practice
Daily science practice for Classes 2–12
Science questions ask students to apply what they know: why a plant wilts, what happens to ice in the sun, which force is at work.
Every daily has science at the student’s own level, from living and non-living things for the youngest to physics, chemistry and biology for the oldest.
Each subject earns 1 to 5 stars from its own rating, and the best 3 subjects build the Ado Rank.
What it covers, by age
- Ages 6–8
Plants and animals, the senses, food, water and weather.
- Ages 9–11
The human body, materials, simple machines, light and sound.
- Ages 12–14
Cells, chemical changes, forces and motion, electricity.
- Ages 15–17
Physics, chemistry and biology at secondary-school level.
Sample questions
What does water turn into when it boils?
Level 4 of 5Show the answer
Answer: Steam
Heating liquid water makes it boil. When water boils, it turns into hot water vapour called steam.
What is the primary method of heat transfer through a solid metal spoon placed in hot tea?
Level 1 of 5Show the answer
Answer: Conduction
Conduction is the transfer of heat through direct contact between vibrating particles in solids, such as metals.
A researcher crosses a pea plant heterozygous for round yellow seeds with a homozygous recessive plant exhibiting wrinkled green seeds. What phenotypic ratio is observed in the resulting generation?
Level 4 of 5Show the answer
Answer: 1:1:1:1
Crossing a dihybrid (RrYy) with a homozygous recessive individual (rryy) represents a dihybrid test cross. This cross produces four distinct phenotypes in an equal 1:1:1:1 ratio.
These questions come from Ado’s question bank and are written with AI help. They are never used in ranked play, so practising them here can’t change anyone’s rank.
