The children were told that in our mantle, they are adults that go to work to earn money. We discussed ways that adults might spend their money and grouped these into wants, needs and emergencies. Each child created their own family with their own saving goal.

We noticed a poster hung from a metal fence. The poster showed a man with builders equipment; a hard hat, goggles, safety boots and other protective clothing.  Just in front of it stood a man. We dressed him in builders equipment just like the poster and explored different builders tools and equipment before creating these to place around him.

The man held a roll of paper in his hands. It showed pictures of a cliff face and the word 'unstable'. It also told us that the top of the cliff was a prime habitat for puffins to nest. We discussed what this could mean... the puffins are in danger of losing their home! 

On our way to Bob, the winds were so strong! Amongst all the noise, we could only hear a few words and had to try to from these into sentences. 

We looked at pictures of puffins and discussed why the cliff face was a suitable habitat for them and made some of our own.  

We created our own cliff and created grasslands on top and water at the base. With the strong winds and wild waves hitting against the cliff, this must have been weakening it over time.

The paper also showed pictures of gabions. We learnt that gabions are stable structures, used to stabilise and protect cliffs from erosion. We decided on a plan; we would place gabions at the base of the cliff to strengthen it and to protect it from the force of the waves. 

We needed to inform Bob and check that the plan could go ahead, so we drafted up plans before video calling him with our idea. He was thrilled!

Now that we had the go ahead from Bob, we could begin our job. 

Out of role, the children were introduced to lots of different vocabulary; structure, stable, unstable, man-made and natural.

They explored the stability of different 3D shapes using playdough and whiteboards. The higher the whiteboard was able to tilt, the more stable the structure was. 

It was concluded that the cuboid and the pyramid were most stable because of their flat faces, but the cuboid's shape would fit the most rocks inside.
