Title	The Water Cycle & The Water Cycle (with Carbon Dioxide)
Purpose	Trying to work out the Water Cycle & Water Cycle with Carbon Dioxide
Materials	Bag 1 1x ziplock bag 1x vivid pen 1 cup Coldwater 2 drops of blue food colouring Bag 2 1x ziplock bag 1x vivid pen 1 cup Coldwater 2 drops of blue food colouring 1x litmus paper 1 teaspoon baking soda
Steps	Bag 1 Get a ziplock bag and a vivid pen Draw the water cycle (label the parts of the water cycle) Carefully pour 1 cup of cold water Carefully drop 2 drops of blue food colouring Stick the ziplock bag in a window where it receives sunlight. Bag 2 Get a ziplock bag and a vivid pen Draw the water cycle Carefully pour 1 cup of cold water Carefully drop 2 drops of blue food colouring Carefully put 1 teaspoon of baking soda Stick the ziplock bag in a window where it receives sunlight
Conclusion	Experiment 1: I think that the outcome of this experiment will be… I think that nothing will happen because the water will go up and down as a cycle.  Experiment 2: I think that the outcome of this experiment will be… In the second bag, I think that the colour will change because there is the baking soda and the litmus paper which changes the colour also adds carbon dioxide to the bag
