The materials produced are too difficult for the 1H students and then the 3ACEM has created this two educational games to make plastic easy to understand for them.

POLIMERISATION

1. The student are "monomers" and holding their hands they link together to form some chains. The chains are indipendent and the polimer is flexible

2. Two students put their hands on the shoulders of their mates who are involved in the formation of the chains. This is a simulationof the cross-linkings between the chains and the polimer becomes more rigid

3. Two students stand between the chains and spin to help the chains slide one over the other

HOW MICROPLASTICS GET INTO YOUR BODY

1. The 3ACEM students created some labels and cards:

• n. 1 fisherman label (FM)
• n. 1 big fish label (BF)
• n. 3 small fish labels (SF)
• n. 6 jellyfish labels (JF)
• n.14 microplastic labels (MP)
• n. 14 microplastic cards

2. Each 1H student is given a "role" and the corresponding label; the MP students are also given the cards

3. A 3ACEM student who plays the Game Leader (GL) shows the space which simulates the sea

4. The GL calls the MP students and they start floating into the sea

5. The GL calls the JF students and they also start floating into the sea but when they come close to a MP student they touch him/her meaning they eat him/her. The MP student gives its card to the JF student quits "the sea".

6. The GL calls the SF students and they "eat" the JFs collecting the cards from them

7. The GL calls the BF student who "eat" the SFs collecting the cards from them

8. Lastly the GL calls the FM student who "eat" the BF collecting all the microplastic cards
