K-PS3 Sunlight and Earth's surface
Aligned to K-PS3 — Next Generation Science Standards.
What this lesson teaches
Sunlight does more than light up the day. It warms whatever it touches, like sand, water, and sidewalks. If something is too hot in the sun, you can cool it down by making shade to block the light.
Worked example
On a sunny day a metal slide can feel hot to the touch, but the same slide under a shady tree stays cool. Putting up an umbrella over a sandbox keeps the sand underneath cooler.
Practice questions
- What does sunlight do to a sidewalk on a sunny day?
- Why does shade feel cooler than the open sun?
- Think of one way to keep a bench cooler on a hot, sunny day.

K-PS3 La luz solar y la superficie de la Tierra
La luz solar hace más que iluminar el día. Calienta todo lo que toca, como la arena, el agua y las banquetas. Si algo está demasiado caliente bajo el sol, puedes enfriarlo haciendo sombra para bloquear la luz.
Ejemplo: En un día soleado, un resbaladero de metal puede sentirse muy caliente al tacto, pero el mismo resbaladero bajo la sombra de un árbol se mantiene fresco. Poner una sombrilla sobre una caja de arena mantiene la arena de abajo más fresca.
