A visit from Ron

Yesterday the Year 3 and 4's had Ron from Waste Wise come and talk to us about different types of materials and how long they last in the landfill.
We had pictures of different materials and we had to put them in order of how long it takes for them to decompose.  We found out that things that were once alive decompose first and some things never decompose.


 

Ron then explained how long scientist think that things take to decompose. Some things don't take long like organic matter - things that used to be alive.  Some things take millions of years like glass and things like plastic never decompose.



What could we do with these materials instead of throwing them out?
