Writing/How does a bike work

L.I:To write an Explanation For writing we had to write an explanation.
First we had to think of a topic.When we have our topic that means
 we can plan.When we have done our explanation plan we write the explanation.

My topic is about how does a bike work.At the end when we do
our summary make sure it links with the photo.

We learnt it by writing an explanation.
We used chromebooks,explanation,plans and ideas.
