On February 27, Ms.Kiley came to my class for lesson 15. This time we would take our stream table, make a stream,  and also make a dam and protectors (toothpicks, popsticle sticks, a straw) so the cubes, houses, wont get flooded by the water that we will pour on lesson 16.

The plan and gravel also so not a lot of water goes through and floods the houses.

We did our usually routine and then we started to make the dam. We got extra materials like the toothpicks. My group thought of making a kind of maze at the head of the stream, then put a part of the straw so not a lot of water will go and only a little will, and also made a wall of sand and gravel.

We are not done but on lesson 16 we will get to finish the dam. And that is what happened when Ms.Kiley came for lesson 15.
