Tin foil river!!

After a morning of digging and exploring rivers in the sandpit, we were becoming frustrated with the water being absorbed into the sandpit, before it reached the end of our river.  We had numerous discussions about why that was happening and what we could do do stop it.  One of the friends in our group, asked why the water in swimming pools doesn't soak into the ground.  So we decided to apply the same theory to our river.  We needed something to separate the water from the sand.  Some of the suggestions were; paper, towels and concrete.  After much discussion we decided to use tin foil.  Then it was time to plan our river.  Everyone had a lot of great ideas about its width and length.  Then everyone helped digging and before long we had dug a river that spanned the entire length of the sandpit!  We each had our job, and thanks to all our friends the task of digging was done!  With our river dug, we were then able to lay the tin foil.  We had to solve the problem of the breeze lifting the tin foil, which was lay a small row of sand along the edge.  Once this was decided, we worked hard to ensure this was completed.  Upon completion, we were able to remove our dam and let the water flow into our river.  Success!!!! The water flowed all the way to the end of our river.  A huge part of our success was due to all the tamariki's  hard work and contribution.  Thanks to everyone for being such great team players, seeing what needed doing and getting on with it!
