Making a Cloud
Making a Cloud
Students are investigating how various air conditions affect weather patterns. They set up an experiment by creating four separate closed containers that model four different air conditions. Each container is made by stacking two plastic cups on top of each other, connecting both openings, and sealing them with tape. The air conditions inside of the containers are created by placing either warm sand or warm water in them. Some of the containers are then cooled by placing ice cubes on top. After 30 minutes, two containers have water droplets on the inside and two containers do not. The pictures show the containers after 30 minutes have passed.

Container 1 has warm sand in the bottom cup.Container 2 has warm water in the bottom cup and water droplets on the sides of the bottom cup.Container 3 has warm sand in the bottom cup and ice cubes sitting on top of the top cup.Container 4 has warm water in the bottom cup and ice cubes on top of the top cup. Water droplets are on the sides of the top cup.

Multiple Choice Question
Which BEST explains the purpose of the investigation?

A.
to show why some weather conditions produce clouds and others do not

B.
to show why clouds only form in warm weather

C.
to show why clouds only form in cold weather

D.
to show why some types of clouds produce rain and others do not

Answer 1

The BEST explanation for the purpose of the investigation is:

A. to show why some weather conditions produce clouds and others do not

This option aligns with the experiment, which aims to demonstrate how different air conditions (warm sand vs. warm water, and the effect of cooling with ice) can lead to the formation of water droplets (clouds) in the containers.
