Year 2 Science: UPCYCLING!

You’ve heard of recycling . . . well, today we rescued empty water bottles from the bin and transformed them into light bulbs that needed no electricity! This is called upcycling.

Inspired by Alfredo Moser, whose idea has transformed the lives of those in parts of the world where electricity is too expensive, we designed an experiment. This involved using the iPads to record our results by taking photographs of Lego people inside of cardboard-box houses when we added 100ml of water to the bottles each time. We then measured the light of each photograph in LUX by using Log-It.

Our Lego person goes into the house.

Using Log-It with the iPads to
see the difference in our photos.

Our data showed us a pattern,
so we could write a general statement.

Our general statement was that, ‘The more water we put in the bottle, the brighter the light in the house.’

If you can't afford electric light, just use water bottles!

Check out the photos we uploaded to The Cloud and see the amazing difference it can make to people’s lives when you take trash and turn it into something more valuable.

Can you work out what our change variable was?

Can you explain how this worked? Here's a clue.
