Δράση
step 1
Introduction – short recap of previous LU.
step 2
Warm-up activity – constructing and presenting the timeline.
step 3
Present the challenge – The printed pictures with waste from LU1 need to be placed on a timeline according to the time it takes the item to decompose.
step 4
Discuss the different types of waste, what they consist of or how to find out what they are made of.
step 5
Divide the class into working groups and choose a picture of waste to investigate.
step 6
Gather information about each type of waste that was found and make a note on the back of the picture to include where it was found, a description of the item, the type of plastic and the length of time it takes to decompose.
step 7
Working in groups, place pictures of waste on the decomposition timeline.
step 8
Discussion – students should develop an awareness of the time it takes to decompose, and that some types of waste never decompose (non-biodegradable).
step 9
Present the timeline for discussion – what is the problem and what can be done to address it?
