Fog and Rainbow experiment

*Watch the fog roll in.

What you need: Glass jar, small strainer, water, ice cubes.

What to do: Fill the jar completely with hot water for about a minute. Pour out almost all the water, leaving about 1 inch in the jar. Place the strainer over the top of the jar. Place 3-4 ice cubes in the strainer. As the cold air from the ice cubes collides with the warm, moist air in the bottle, the water will condense and fog will form.

* Reflect a rainbow.

weather activities

What you need: Glass of water, sheet of white paper, sunlight.

What to do: Fill the glass all the way to the top with water. Put the glass of water on a table so that it is half on the table and half off the table (make sure that the glass doesn’t fall!) Then, make sure that the sun can shine through the glass of water. Next, place the white sheet of paper on the floor. Adjust the piece of paper and the glass of water until a rainbow forms on the paper.

How does this happen? Explain to students that light is made up of many colors: red, orange, yellow, green, blue, indigo and violet. When light passes through the water, it is broken up into all of the colors seen in a rainbow.
