The afternoon children had fun thinking about solids, liquids and gases this week.
First, we poured a liquid (apple cider) into popsicle molds. These turned into a (YUMMY) solid once frozen.
We compared ice to dry ice by placing ice cubes in a plastic bowl.
We then observed what happened when warm water was poured over them. (They turned into a liquid).
Only the teacher touched the dry ice with tongs. It was very cold (-100 degrees F which can harm the skin). The metal tongs made a strange sound when they touched the dry ice.
The children carefully took turns touching the vapor made by the dry ice and the warm water. The water droplets attach to the dry ice gas and form tiny droplets. It was fun to fan the vapor.
