During science today, we got to explore hot and cold water. Each group had a cup of very cold water and a cup of very warm water. First we put our index finger into the warm water and described what it felt like, then repeated this with the cup of cold water. Next we used a dropper to carefully squirt pink food colouring into the cup of very warm water and watched the entire cup of water turn pink.
My group dropped blue food colouring into the cup of very cold water and watched awesome patterns form from the top to the bottom of the cup.
The food colouring did not mix with the cold water like it did in the cup of warm water. Some of us noticed the warm water turned dark purple when we mixed blue with the pink food colouring in the warm water.
