Science Experiment

We have be looking at three bottles with a bottle on top of them. With water and some other thing in them, like dirt and salt. One of them has just water, another has dirt, and the other one has salt. Every day we come into school and we look at them. The water in the bottles evaporated a little bit. There are little drops in the top bottle and less water in the bottom bottle. We noticed that they all have evaporate a different amount of water ever day. By Jack
