What to know The Sun transfers radiant energy to Earth. Objects in sunlight can gain heat and increase in temperature. Measure before and after under controlled conditions to show the change. 🔎 Think like a scientist Two matching cups start at 22°C. After sunlight, one reaches 30°C while a shaded cup reaches 24°C.

What to know Shade blocks direct radiant energy from reaching an object. Without continued heating, an object may cool as heat moves away. Clouds, night, and cover can reduce incoming sunlight. 🔎 Think like a scientist A sun-warmed paving stone cools after sunset because it no longer receives solar energy and transfers heat to its surroundings.

Sources of Light and Heat Learning goal: Connect the Sun with the broader pattern that many light sources also release heat.
What to know The Sun provides both light and heat energy to Earth. Many—but not all—objects that give light also give heat. Measurements provide stronger evidence than a guess. 🔎 Think like a scientist Sunlight and a glowing bulb can both warm a surface, but the Sun is Earth’s major natural source of radiant energy.
