The first activity to be translated is Còctel erosiu or, in English, 'Rock, rattle and roll'. This activity investigates rock resistance and helps pupils to understand why mountains and hills are generally made of more resistant rock than valleys and lowland.
The ELI team would be very grateful if someone could send a better short video clip than the one we are using to demonstrate this activity!
