Professor Picklebottom

Coolest Cup Challenge

Professor Picklebottom is planning the perfect summer picnic, but he has one big problem... his ice keeps melting! Should he use a metal cup, a glass, a paper cup or something else? 


Help him investigate which material keeps drinks cold the longest before his lemonade turns warm!

Congratulations!


  • You've discovered that some materials let heat move into the ice much faster than others.

  • Now think beyond today's investigation...

  • If you wanted to keep a drink cold on a hot summer day...

Which cup would you choose?

The Crazy Scientist LAB Learning System™

Every experiment follows The Crazy Scientist Lab Learning System™ — a simple way to help kids think like real scientists.

We

  • LINK to what they already know,

  • ACTIVATE curiosity through hands-on discovery

  • BUILD understanding that actually sticks.

Imagine you're outside on a hot summer day with an icy cold drink.


It's hot, you're thirsty and the last thing you want is a warm drink!

Would a metal cup keep your drink colder for longer? What about a glass, a paper cup or even wrapping it in a napkin?


Before you guess, let's investigate and discover which material is the coolest!

Time to become a Heat Detective!


Place one ice cube on each material and start your timer.

Watch carefully as the ice cubes begin to melt.

Which material keeps its ice the longest?

Did your prediction match what you observed?

Congratulations, Heat Detective!


You discovered that not all materials let heat travel at the same speed.


That tiny ice cube helped explain why we use different materials every day:


  • Insulated drink bottles keep drinks colder for longer.

  • Paper coffee cups stop your hands from getting too hot.

  • Oven mitts protect you from hot baking trays.

  •  Cooler bags help keep picnic food cold.

Engineers choose materials very carefully. Sometimes they want heat to move quickly... and sometimes they want to slow it down!

Think Like a Scientist

Scientists don't just do ONE experiment; they change one part of the experiment (independent variable) and then see how it affects another part of the experiment

(dependent variable)

Change ONE variable and test again.

Does the size of the ice cube change how quickly the ice melts?

Can you improve a cup to keep the ice colder for longer?

Vocabulary

Material

A material is a substance used to make objects. Different materials have different properties that make them useful for different jobs.


Heat

Heat is a form of energy that moves from warmer objects to cooler ones. This energy transfer can change the temperature of a material.


Thermal Conductor

A thermal conductor is a material that allows heat energy to move through it easily. Metals are usually good thermal conductors.

Running the experiment is easy; however, teaching it well is another challenge.

Teachers often ask:

How do I adapt this for Stages 1,2 or 3?

What misconceptions will they have?

What syllabus outcomes does it cover?

What do I do with fast finishers?

How do I structure this for a full class?

What do I say when they ask WHY?
