THINGS TO SEE AND DO: MAKE A GIANT SAND OCTOPUS.

IMG_4963 We have built large sand sculptures before, and they are a great hit for the young construction workers. This time however we had a change in focus beyond a simple sculpture, we want to talk a bit about camouflage.

We chose an appropriate spot and drew a large circle in the sand (for the body). Each child took control of one tentacle (mapping it out and digging around their shape to pile it up as a long 3d sand arm).

We didn’t have 8 children building tentacles at once so this allowed for some great maths questions during construction; how many have we made now? How many do octopuses have? How many more do we need to make?

As the tentacles shaped up the kids moved on and created the body and eyes in the centre, decorating with shells. The small group used great negotiation techniques throughout the process to organise themselves to finish the octopus, helping each other when they needed it, and collectively deciding on plans.

Now, that’s a great physical project, but it was not our focus as we built. We wanted to talk as much as we could while building – What do the kids know about octopuses? (They take a long time to have their babies, they live in the water, they shoot ink at predators, they have no bones – these were the things the kids collectively knew about octopuses and it was a delight watching them inform each other and add to the knowledge that the other children were sharing.)

When we came to the idea of camouflage we stayed on the topic for a little longer. We talked about what would be good camouflage for an octopus, and how it can manipulate the shape of it’s skin to form different textures. It can change the shape of it’s body to mimic other creatures, and can even change the colour of it’s skin to form different patterns to blend into it’s surroundings! No other creature has all these camouflage skills.

In our case we talked about our octopus being ‘camouflaged’ in the sand around it, but over the next couple of days we will revisit the concept as the opportunities present themselves. (See how that bird blends into it’s background? Why do you think that tiger in the book has stripes? What makes good camouflage? Why is it important for each of these animals to be able to hide?) Camouflage is a topic that is of great interest when learning about animals and it will come up time and time again as we work our way through the year, and a physically active project of building a sand sculpture is a fun way to introduce it!
