Learning for Life (Fulfilment)

1. For the children to consider how God is solid and steady like a rock.

2. For the children to gain a simple understanding of how one type of rock (fiery rock) is formed.

3. For the children to become more aware of the rocks and stones around them, as we begin to focus on rock.

Rock formed under water
Week 2

Truth to Teach (Source)

1. God has found a way to sustain what He initially created.

2. Some rocks are formed under water.

Way to Work (Means)

1. Ask the children to tell you some things they remember about fiery rock. (Make sure the
children have had an opportunity to look at relevant rock samples.)

2. Explain that fiery rock is one type of rock God has made and indeed continues to make.
Another way in which He causes rock to be formed is under water. Let me tell you how this
process works, and I think you’ll realise that it happens slowly.

3. We can start this process on land. Up in the mountains when rain falls, it often settles in
little holes or cracks in rocks. When the temperature drops to freezing, what will happen to
the water? (It will freeze.) What you may not know is that when water freezes to form ice,
it takes up more space. When it is in a small space in a rock, it can spread out or expand
with such force that little pieces of rock can get broken off.

4. The rain and wind may wash these pieces of rock into streams and rivers, where they may get
broken up further and carried far downstream towards the sea. When a river enters the sea
it may be carrying quite a lot of mud in its water. This begins to sink down to the bottom of
the sea, called the sea-bed. (Illustrate this on the board as you teach.) As well as mud and
sand and little stones sinking to the sea-bed, little sea creatures that swim around will sink
down there when they die. Many little sea creatures have shells to protect themselves.

These settles on the sea-bed too. Over a long time all this begins to build up layer upon
layer, squashing the bottom layers into rock!

5. One rock formed in this way is chalk. Show samples of chalk and also pictures of chalk
cliffs on the south coast of England or of the horse at the White Horse Hill. Chalk is quite a
soft rock, and you can easily score it with something hard.
