Materials - Who is who?

Which material do I have in the bag?

• Make teams of 4 people.

• Each team writes a list of 4 to 8 different materials and make sure they know the properties of them and what they are used for.

• The teams take turns to make questions that can be answered by "yes", "no", "quite", "not really" in order to guess which material the other team has in its bag? Each time the question must be asked by a different member of the team.

Is it ... [adjective]?Is it good for making ... [object]?
Is  it ... [material]?
