Activity 01
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.
Analyze how the sun helps plants grow.
Facilitation TipDuring Shadow Tracking, have students record stick positions and shadow lengths at the same time each day to highlight consistent daily patterns.
What to look forAsk students to draw two pictures: one showing a plant growing in bright sunlight and another showing a plant in a dark place. Have them label each picture and write one sentence explaining which plant will grow better and why.

Activity 02
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.
Explain why the sun feels warmer in summer than in winter.
Facilitation TipIn Temperature Check, ask pairs to measure and compare temperatures in sun and shade after 5 minutes to build wait-time for accurate results.
What to look forPose the question: 'Imagine there was no sun. What would happen to plants, animals, and people?' Guide students to discuss the lack of light, warmth, and food sources, prompting them to justify the sun's importance.

Activity 03
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.
Justify the sun's importance for all living things.
Facilitation TipFor Seed Sun Test, give each pair two identical pots and guide them to label ‘sun’ and ‘shade’ before planting to ensure clear comparisons.
What to look forGive students a card with the sentence starter: 'The sun is important because...'. Ask them to complete the sentence with one reason, then draw a small picture to illustrate their answer.

Activity 04
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.
Analyze how the sun helps plants grow.
Facilitation TipUse 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.
What to look forAsk students to draw two pictures: one showing a plant growing in bright sunlight and another showing a plant in a dark place. Have them label each picture and write one sentence explaining which plant will grow better and why.

Generate Complete Lesson→A few notes on teaching this unit
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.
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.
Watch Out for These Misconceptions
During the Tilt Demo, watch for students who think the lamp (sun) moves closer to the globe (Earth) in summer.
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.
During the Seed Sun Test, watch for students who believe plants grow well with only soil and water.
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.
During Shadow Tracking, watch for students who think the sun moves across the sky and causes shadows to follow it.
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.
