What is the free Grade 4 Science Quiz?
The Grade 4 Science Quiz is a free web app for reviewing elementary science with short original 4-choice questions. It is easy to use for student practice, home study, class review, and quick vocabulary checks.
The quiz covers air and water, temperature changes, electric current, body movement, seasons and living things, rainwater and ground, weather and water changes, the Moon and stars, and observation and experiment skills.
What makes this quiz site useful?
- Choose a short course by unit, or use a larger mixed course for broad review.
- Practice in a time-attack style that makes repeated review feel like a small challenge.
- Use ranking, My Page history, and often-missed question records to notice weak areas.
- Check hints and simple self-made diagrams when a question needs visual support.

Review Grade 4 science by topic
Students can practice one topic at a time, such as air and water properties, electric current, weather and temperature, or the Moon and stars. This makes it easier to review only the unit that needs more practice before a class test.
Teachers can use the quiz as a short warm-up, a review activity after a lesson, or a simple check of key science vocabulary.
Observation, comparison, and reasoning
Questions are written around everyday observations and simple experiments. Learners compare conditions, notice changes, and choose an answer with a clear reason instead of only memorizing terms.
Students can review air and water properties, electric circuits, weather and water changes, Moon phases, star position changes, and experiment skills.
Hints and self-made diagrams for each question
Hints change with each question and include self-made SVG-style diagrams for air, water, heat, circuits, the body, seasons, rainwater, weather, the Moon, stars, and sky observations.
