Grade 3 · Discovery Space
Grade 3 science asks for the cause, not only the name: why the seasons change, why a lever helps, how sound reaches an ear. Daily Academy closes each daily session with one short explanation of a real thing and questions that check whether the mechanism landed.

Canadian provinces write their curricula separately and word them differently, but the grade 3 expectations below are common across all of them. Daily Academy is skills-based rather than built to any one province’s document — see how it maps to your province.
'Gravity' is a label. Why a heavier ball does not fall faster is the science. Grade 3 is early enough that the habit of asking for the mechanism can still be set easily.
Most grade 3 science difficulty is reading difficulty wearing a lab coat. Because the readings here carry comprehension questions, the parent dashboard can tell you which of the two is actually slipping.
Straight from the library, at the difficulty they are served at. Every question carries an explanation that appears after answering, whether the answer was right or wrong.
Living Things
How many things does every animal need?
Why: 4 things: food, water, air and somewhere safe to live.
Earth & Space
Does the sun really go away at night?
Why: No. The Earth turns, and your part of it faces away from the sun.
How Things Work
What does the stone do in the bath?
Why: It sinks. The duck floats and the stone sinks.
Health & The Body
What do you smell with?
Why: Your nose. Each sense has its own part of the body.
Mastery is estimated per skill, never per subject, so strength in one can never average away a gap in another. Each page below carries a question you can ask tonight to check it yourself.
Wording varies by province, but grade 3 science across Canada generally covers plant and animal growth and habitats, forces and simple machines, structures and materials, light and sound, and Earth in space including day, night and the seasons.
Each discovery activity is a short original explanation written for this age, followed by questions on it. The reading is the teaching; the questions check whether the mechanism was understood rather than whether the words were remembered.
Twenty minutes, five stops, and every question pitched at your child rather than at their year group. The daily mission is free and stays free.
