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 lesson
The sun warms up everything it touches. A shade blocks the sun's rays. Under a shade, the ground stays cooler.
Try it together
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.
Good to know
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.

Then practise
8 questions wait behind this lesson, each with its answer explained. Every answer feeds the sky: stars light as they are learned, and dim when it is time to come back.
