Students observed salt crystals and compared them to salt chunks that we use at home.

Students experimented with dissolving sugar in cube and grain form and then in hot and cold water.
Students continued their investigations of mixing solids and liquids with trying to separate each of the solids from the water. We learned that we could separate the gravel and tissue paper from the water with coffee filters, but the salt was dissolved. We will see if evaporation will help us separate the salt from the water.
Today in science, students mixed gravel, salt and bathroom tissue with water to observe the changes some solids make when they are combined with liquids.
Second graders mixed two solids together (salt and gravel) and then separated them using a screen. They found that the mixture of salt and gravel didn't change the properties of either solid.
Today, second graders read about changes and we talked about changes that happen quickly and changes that take a longer period of time. We also reviewed how water changes states of matter.
Second graders observed our courtyard tree in the winter season and observed the surroundings with the snow. We took our picture with the tree.
Today in science, second graders observed the water we left on the windowsill evaporated. We also observed that warm water condensed and made steam.
