Daily States of Matter tests for Lower KS2
Solids, liquids, and gases, changes of state, and the water cycle. These questions are designed specifically for children ages 7–9.
Sample Lower KS2 questions
A preview of what your child will practice. Dailulu generates fresh questions every day.
Water can exist as a solid (ice), a liquid (water), or a ____ (water vapor).
Water can change states based on temperature and pressure, showing its properties as a gas, liquid, or solid.
What happens to a balloon filled with helium when it gets colder?
As the temperature drops, the helium inside the balloon contracts, making the balloon smaller and potentially causing it to sink.
Sort the transformations of matter from solid to gas when heated.
- Solid
- Liquid
- Gas
The process involves melting from solid to liquid and then evaporating from liquid to gas when heated.
Gases have a fixed shape and a fixed volume.
Gases do not have a fixed shape or volume; they expand to fill any space they are in.
About States of Matter at Lower KS2
At Lower KS2, children aged 7–9 are ready to tackle States of Matter with confidence. Dailulu's daily tests use short, focused sessions — just a few minutes a day — to build fluency and retention over time. Rather than cramming, consistent daily practice is the most effective way for children to master States of Matter.
Every question on Dailulu is checked, calibrated for age, and rotated daily so children never see the same test twice. Parents can track streaks and scores from the dashboard.
