IT’S DESSERT TIME!
CASE STUDY
Sharon’s parents have organised a 21st
birthday party for her. Sharon’s mother
wanted to prepare a cold dessert. She asked
Sharon and her brother, Jovan to find a
container that could keep the dessert cold.
“Mom, there are a few containers in the
kitchen cabinet. Which one should I choose?
The plastic, the metal or the glass container?
Sharon asked her mother, who was busy
preparing the food for the party.
“I will use the metal container, of
course! Metal causes hot things to become
cold faster. So when we put the dessert in the
metal container, it will remain cold,” Jovan
said confidently.
“I disagree! I think the plastic container
will keep the dessert cold for a longer
duration,” Sharon argued.
“Stop bickering! Please make up your
mind quickly!” Mother shouted. The two
siblings stared blankly at each other, not
knowing which container to choose.
