States of Matter - Water & Dissolving

We have been learning about states of matter.
We already know that water is a liquid, but know we know when it is cooled to 0 degrees Centigrade it becomes a solid called ice. When it is heated to 100 degrees Centigrade it boils and turns into a gas called water vapour. Yesterday we did a little experiment to see water turn into a gas.
Today Room 2 joined us for a scientific exploration of water and salt. We mixed 7 teaspoons of salt in half a cup of boiling water. We checked to see whether the water level in our cups rose. We all had a turn stirring it and then we put some food colouring in. Some of us had a taste - ewww yuck!

Then we painted with our salt mixture, creating beautiful works of art. We worked together, sharing and waiting patiently for each person to paint with each colour.
