Mass Conversions (g, kg)
Students will convert between grams and kilograms, solving related problems.
Key Questions
- Justify why 1.5 kg is equivalent to 1500 grams.

About This Topic
Day, Night, and the Seasons explains how the Earth's rotation and its tilt as it orbits the Sun create our daily and yearly cycles. Students learn that the Sun only appears to move across the sky because the Earth is spinning on its axis. This topic is a core requirement of the KS2 Science curriculum, focusing on the Earth's rotation to explain day and night and the apparent movement of the sun across the sky.
This unit is essential for understanding timekeeping, navigation, and global climates. It helps students move from a geocentric (Earth-centered) view of the world to a more accurate heliocentric (Sun-centered) understanding. This topic particularly benefits from hands-on, student-centered approaches like using globes and torches to simulate the Earth's rotation and observing shadow movements in the school playground.
Active Learning Ideas
Inquiry Circle: Shadow Tracking
On a sunny day, students place a stick (gnomon) in the ground and mark the position and length of its shadow every hour. Back in the classroom, they discuss their results in groups to explain why the shadow moved and changed size, linking it back to the Earth's rotation.
Simulation Game: Day and Night Around the World
In a darkened room, one student holds a torch (the Sun) while another slowly rotates a globe (the Earth). Other students identify which countries are in daylight and which are in darkness at different points, helping them visualize why it is night in Australia when it is day in the UK.
Role Play: The Tilted Earth
Students work in pairs, one as the Sun and one as the Earth. The 'Earth' student must orbit the Sun while keeping their body tilted at a constant angle. They discuss which part of their body (Northern or Southern Hemisphere) is leaning toward the 'Sun' at different points in the orbit to explain the seasons.
Watch Out for These Misconceptions
Common MisconceptionThe Sun moves around the Earth.
What to Teach Instead
Because we see the Sun 'rise' and 'set,' it feels like it is moving. By having a student spin in a chair while looking at a stationary object, they can experience how their own rotation makes the world look like it is moving, a concept best reinforced through physical simulation.
Common MisconceptionSeasons are caused by the Earth getting closer to the Sun.
What to Teach Instead
Many students think summer happens because we are physically nearer to the Sun. Using a tilted globe and a torch, students can see that it is actually the angle of the Sun's rays and the length of the day, caused by the Earth's tilt, that creates the temperature change, not the distance.

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
