ACTIVITY: Depositing sediments
MATERIALS:
• A large see-through jar. You can make this from a 2-litre
cold-drink bottle.
• dierent places for groups to collect sand and soil.
Teacher's Note
For this activity, divide the class up into 5 groups – one for each
day of the school week (Monday to Friday). Each group must
collect sand or soil from a dierent place so that the dierent
layers are evident by the end of the week. At the beginning of
each lesson for the week, you can ask the group for that day to
pour their sediment in and then carry on with the rest of the
lesson. By the end of the week you can look at the layers of
sediment that each group added. Explain to the learners that you
are speeding up the process.

2. Group 1 must collect a large jam-tin full of sand and on
