Hello guys,
Here is what we have been doing to do with recycling and the Comenius project at our school - we made recycled instruments.

We began by using this “instrument lab” to introduce our new project in DT yesterday and the children loved it http://www.nyphilkids.org/lab/main.phtml? (instrument lab)

We then made our instruments – can you guess what we used to make them?

For further details of instruments and landfill harmonic see:
Also, this is quite a nice explanation of the different instruments and how sound works

Here's a short clip on the landfill harmonic  http://thegospelcoalition.org/blogs/justintaylor/2013/07/20/the-recycled-orchestra-playing-instruments-made-out-of-trash/

And here's a more in-depth versionhttps://www.youtube.com/watch?v=sJxxdQox7n0

Have fun!
