What a learner can do afterwards
- Design a structure intended to reduce the warming effect of sunlight on an area
- Build the structure using available materials and test whether it reduces temperature
- Compare the temperature in the shaded area vs an unshaded area as evidence of effectiveness

The sun warms up everything it touches. A shade blocks the sun's rays. Under a shade, the ground stays cooler.
Mia built a shade from a big sheet and two sticks. She checked the temperature under the shade and in the sun. The shade spot felt cooler.
Pick materials that block light, like cloth or cardboard. See-through plastic lets sunlight through. It does not block much heat.
A shade blocks sunlight, and testing proves it keeps a spot cooler.

The sun sends down light that warms everything it touches. A dark stone in full sun gets hot fast. The same stone under a cover stays much cooler. A shade works by blocking the sunshine before it can heat a spot. Then you test it by feeling the shady spot and the sunny spot.

Builders plan before they build. They pick strong stuff, they measure, and they check that the shape does its job. A shade is a small building job. You pick a cover, you hold it up with sticks or string, and you leave room for air to move under it. Then you check your work. Put one hand in the shade and look at the sunny ground next to it. If the shade is cooler, your plan worked.
