Tides and Maps at Marpool School
How does the tide work? What shape is the eastuary? How does a map work? Who is it for? We explored such questions as these in 2 days of workshops with one class from Marpool school, one day on location by the estuary making observations and being the tide (!) and one quick session making our maps.
Day one down at the slipway at the recreation ground at low tide (coming in): The class split up into pairs or small groups armed with ipads and observation forms. Notes were taken, some drawings made, ipads held and pressed and inevitably some got their feet wet (not the idpads)!
Then we acted out the tides splitting the group roughly into two with one group being the incoming sea tide and the other being the river meandering down the estuary. We appraoached then clashed and for a short spell the tide prevailed but then it retreated and the river pursued it! Not quite a rugby scrum but we felt the pressure as the river was forced either to go round or retreat. No-one was hurt in the making of this live illustration!
Back in class the following day we had a short time (half a morning) to make our maps and they got really exciting! We had legends (keys), wiggly river channels, wildlife maps and 3D elements. There was a choice of coloured paper and soft pastels which produced lovely organic marks. Lots of rapid cutting produced the estuary shapes, some with low tide river channels. Then we added what we know about the estuary.
It was amazing what the kids knew and learnt about the moon and the tides. Many thanks to Marpool staff and kids for all their hard work.
