The Sun and Its ImportanceActivities & Teaching Strategies
Active exploration helps young learners grasp abstract solar concepts through concrete, hands-on experiences. When Year 2 students track shadows, measure temperatures, and grow seeds, they connect the sun’s role in daily life to measurable outcomes they can see and touch.
Learning Objectives
- 1Explain how sunlight provides energy for plants to grow.
- 2Compare the amount of heat received from the sun during summer and winter months.
- 3Identify at least three ways the sun is essential for living things on Earth.
- 4Analyze how the length of daylight hours changes between summer and winter.

Shadow Tracking: Daily Patterns
Stick upright poles in the playground at intervals. Small groups mark shadow lengths and directions every 30 minutes for an hour. Back in class, they draw timelines and discuss why shadows shorten at midday.
Prepare & details
Analyze how the sun helps plants grow.
Facilitation Tip: During Shadow Tracking, have students record stick positions and shadow lengths at the same time each day to highlight consistent daily patterns.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Temperature Check: Sun Versus Shade
Pairs take thermometers outside to record air temperature in full sun and deep shade spots after 5 minutes each. Note times and locations. Share findings on a class chart to spot patterns.
Prepare & details
Explain why the sun feels warmer in summer than in winter.
Facilitation Tip: In Temperature Check, ask pairs to measure and compare temperatures in sun and shade after 5 minutes to build wait-time for accurate results.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Seed Sun Test: Growth Comparison
Plant identical cress seeds in pots: place half in sunlight, half covered in a box. Water daily and measure heights weekly for 10 days. Pairs sketch observations and predict outcomes.
Prepare & details
Justify the sun's importance for all living things.
Facilitation Tip: For Seed Sun Test, give each pair two identical pots and guide them to label ‘sun’ and ‘shade’ before planting to ensure clear comparisons.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Tilt Demo: Seasonal Angles
Teacher uses a lamp as sun and tilted globe as Earth. Whole class observes shadow lengths at summer and winter positions. Students feel hand warmth differences and note angle effects.
Prepare & details
Analyze how the sun helps plants grow.
Facilitation Tip: Use the Tilt Demo with a lamp and globe to show how a 23-degree tilt changes light angles without moving the lamp closer or farther.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Teaching This Topic
Teachers should blend direct instruction with guided inquiry, using clear models and repeated observations to build understanding. Avoid over-explaining; let evidence from activities drive student reasoning. Research shows that young learners benefit from frequent, short cycles of prediction, observation, and discussion to solidify concepts.
What to Expect
Successful learning shows in clear explanations of seasonal changes and plant needs, supported by accurate observations and data records. Students should confidently link sunlight to warmth, growth, and shadow patterns using evidence from their activities.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Tilt Demo, watch for students who think the lamp (sun) moves closer to the globe (Earth) in summer.
What to Teach Instead
Use the tilt board to show how the angle of light changes when the globe tilts toward or away from the lamp. Ask students to compare shadow lengths and warmth at each position to disprove distance changes.
Common MisconceptionDuring the Seed Sun Test, watch for students who believe plants grow well with only soil and water.
What to Teach Instead
Have students compare cress seeds in light and dark pots over five days. Ask them to measure growth and observe leaf color differences to show sunlight’s role in food production.
Common MisconceptionDuring Shadow Tracking, watch for students who think the sun moves across the sky and causes shadows to follow it.
What to Teach Instead
Use a fixed stick and chalk marks to show how Earth’s rotation changes shadow direction and length consistently. Ask students to explain why the shadow always points west at 3 p.m. based on their data.
Assessment Ideas
After the Seed Sun Test, ask students to draw two plants—one in bright sunlight and one in a dark place—and write one sentence explaining which will grow better and why, using their experiment results.
During the Seed Sun Test wrap-up, pose the question: ‘Imagine there was no sun. What would happen to plants, animals, and people?’ Guide students to discuss lack of light, warmth, and food sources, prompting them to justify the sun’s importance with evidence from their observations.
After the Temperature Check activity, give students a card with the sentence starter: ‘The sun is important because...’ Ask them to complete the sentence with one reason and draw a small picture to illustrate their answer.
Extensions & Scaffolding
- Challenge: Ask students to predict and test how a plant grows when given only 2 hours of sunlight each day, using a timer and a cardboard box cutout.
- Scaffolding: Provide pre-printed graphs with labeled axes for students to plot temperature or shadow data before they create their own.
- Deeper exploration: Have students research and present how animals adapt to seasonal changes in sunlight, using books or short videos as sources.
Key Vocabulary
| Photosynthesis | The process plants use to turn sunlight, water, and air into food for energy. This is why plants are often green. |
| Solar Energy | Energy that comes from the sun in the form of light and heat. |
| Orbit | The curved path that the Earth takes as it travels around the sun. |
| Tilt | The angle at which the Earth is leaning as it orbits the sun, which affects how much sunlight different parts of the Earth receive. |
Suggested Methodologies
Planning templates for Science
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 PlannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
RubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
