The Big Watermelon Experiment:
Physics, Forces and Flying Fruit

Have you ever wondered how many rubber bands it takes to implode a watermelon?

Dr Rob certainly has, and he’s destroyed many melons seeking the answer. And now he needs your help.

Culminating during National Science Week (August 15 – 23), we want schools to take part in one giant (and somewhat messy) science experiment.

What do schools need to do?

For starters, register using the form below.

This will mean you get the regular updates from us and don’t miss out on any watermelon madness.

How does it work?

The mini-lessons (videos and pdf downloads) are now available for registered schools on the resources page. These feature Dr Rob introducing teachers and students to the experiment, including:

  • The practicalities of setting it all up;
  • Science by collaboration;
  • Balanced (and unbalanced) forces at work;
  • How on earth it fits into the real world.

During (or close to) Science Week, everyone finally implodes their watermelons and uploads their results (including any great pictures/video they may have).

The data will be available for everyone, to marvel at, analyse, or even just help answer the question once and for all!

Watermelons are tightening their belts

Woolworths bring in the fresh melons

Woolworths have kindly agreed to support schools taking part by supplying the first 200 schools registered (yep, we are actually over that now) with gift cards to buy their melons. What a super supermarket.

Dr Karl named as Big Watermelon Experiment Patron

Dr Karl has graciously agreed to lend his support and enthusiam to the mass imploding of watermelons. Hooray and welcome Dr K.

Is this really science?

Yes indeed. It is one big experiment. Each school is essentially doing one (or more) trials in the experiment to gather as much data as possible.

There will be predictions, plans, dependent and independent variables, measurements, even a little maths.

It is a great example of collaborative science, something that happens the world over (usually for more scientifically important reasons).

All the data that is collected will be available to participating schools should they wish to analyse it and search for trends (or just see how their melon compared).

Is all this free?

Yes. All the mini-lessons (video and pdfs) will be made available to participating schools so they can go on the journey to watermelon armageddon together. The only expenses may be materials (watermelon and rubber bands) but we are working on partners for that too.

Pros

  • Fun engaging and (yes) educational event to run during National Science Week
  • Great to do with a whole class or year level
  • Free lessons provided (they won’t feel like lessons)
  • Suitable for Primary or Secondary students 
  • Great opportunities for the school to run some science social media and engage their community
  • It is easy to organise and minimal effort/materials required to take part
  • Kids will love it (as will the teachers)
  • Free watermelon leftovers for everyone!

    Cons

    • Hmmm can’t think of one…

    Register for your school now

    To register your school to participate, just fill out this form. We recommend planning on doing 1 watermelon per class or year group. Ideally sign up once per school, but more is ok too.

    The Big Watermelon Experiment is being run by Dr Rob and Experimentary, because we love science (you’re welcome).
