IT’S TIME FOR DESSERT!

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.

Activity 1: Case Analysis Sheet

What Do I Know? What Do I Need To Know?

ACTIVITIES

Activity 2: Experiment• In their groups, identify the question to be addressed in

the case. Using the materials given, design and conduct an experiment to explore the question.

• What question are you addressing?• What is the aim of the experiment?• State the changed variable.• State the constant variables.• State the measured variable.• Draw a table to record the results.• What can you conclude about your experiment?

STUDENT PRODUCTS

(I) Mini Poster• Your poster needs to include the following:• The title of your experiment• The experimenters’ names• The aim of the experiment• A drawing of the experimental set-up• A procedure of how the experiment was conducted• Results• Conclusion

(II) Creation of an insulating container/box• The insulating container/box must be made out of recyclable materials• The insulating container/box must be able to keep a bottle of hot water hot as

long as possible.
