Science
Irreversible Changes are Chemical Changes where the original material cannot be recovered.
Coke and mint experiment
Yeast and warm water experiment
Investigating Irreversible Changes with bicarbonate of soda and different liquids.
Separation Experiment.
How can we separate three different solids from water?
Our ongoing experiment to discover if we can recover a solute from a solution.

The salt water solution will be left on the windowsill. We will observe what happens over the next few weeks…..

After one week the water has significantly reduced by evaporation after being left on the sunny windowsill.

WOW! The experiment has worked! All the water has evaporated and salt crystals are left in the cup.
Today the Piel scientists investigated whether the temperature of water, the amount of solute and if we stir the solution aids the dissolving process….
Which materials dissolve?
Today we investigated which materials are soluble and insoluble.
Armed with paper and tape, we made boats using our knowledge of air and water resistance.
