Unit 6 Subconcept 1 - A Child's Place in the Environment (ACPE)

Sixth-grade students at the Lakeport Elementary School made a solar
still by:
• digging a hole in the ground
• placing a jar in the center of the bottom of the hole
• draping a piece of plastic over the hole
• shaping the plastic to form a funnel and resting the tip of the
funnel-shaped plastic inside the container
• securing the plastic with two rocks
After two days the students observed water in the container.
3. How did the water get into the container?
! A. The sun evaporated the water from the soil. The water evaporated from
the plastic and condensed inside the jar.
! B. Heat from the sun evaporated the water from the soil. The water
condensed on the plastic and ran down the funnel into the jar.
! C. The sun conducted the water from the soil. The water condensed on the
plastic and dried up before it could run down the funnel and into the jar.
