= What happens to the egg shell when eggs are left in different liquids? =

By Cross - =  __Task 1: Answer these Questions__  =

It is a chemical reaction.
 * 1) What is an egg shell made of? calcium carbonate which is the same stuff that shells, pearls, chalk and limestone caves are made out of.
 * 2) Why does vinegar dissolve the egg shell? Vinegar has acetic acid in it. The egg shell is made calcium carbonate. The acid in the vinegar separates the calcium from the carbonate. The calcium floats away into the vinegar and the carbonate turns into carbon dioxide.
 * 3) What is vinegar? It a liquid that smells and tastes funny - it is an acid.
 * 4) What kind of reaction is an egg shell dissolved in vinegar?

==  __Task 2: List your independent, dependent and controlled variables:__  ==

__1. Independent variable: I will__ __change the type of liquid: I will use ginger ale, water and vinegar__

__2. Dependent variable:__ texture of egg shell

__3. Controlled variables:__ the time the lightness the amount of liquid

=  __Task 3: What is the hypothesis for your experiment?__  = I think that vinegar will change the texture of the egg shell the most

=  __Task 4: What equipment do you need for your experiment?__  = vinegar 3 raw eggs 3 jars that are the same size water ginger ale vinegar measuring jug cramra =  __Task 5: List all steps in the method of your experiment (try and include a diagram or video that helps explain):__  =

__**Task 6: Observation and discussion**__

Note down what you noticed as you did each experiment. Try and include an image or a video or photos of your experiment.

__Experiment 1 Observations: 120ml of water,vinegar,ginger ale 3 eggs pour 120ml ginger ale in a jar put the biggest one in a jar for 7 days__

__Experiment 2 Observations:120ml of water,vinegar,ginger ale 3 eggs pour 120ml vinegar in a jar put the medium one in a jar leave it a jar for 7 days__ f __Experiment 3 Observations:120ml of water,vinegar,ginger ale 3 eggs pour 120ml of water in a jar put the smallest one in a jar leave it for 7 days__
