Wow Keb, I was a little worried due to your relaxed approach to Science Fair however you have done a brilliant job! Your experiment was interesting and you have done some good learning. I was pleased to see that you backed up your experiment with research about the difference between sugar and salt which gave you an explanation of why the salt dissolved fastest. Well done Keb! I think that i did much better on my science fair than i did last year presentation wise and information wise. I had lots more information to do with my experoment and my explanation was good to.

Salt VS Sugar __**Introduction**__ My topic is which dissolve the best/fastest in White vinegar, Sparkling water, ginger ale, glass cleaner, Lemonade, Ice tea or Tea, apple juice. I choose this topic because i wanted to see if salt or sugar dissolves fast or slow. __**Aim**__ My aim is to try find out which dissolves fastest sugar or salt in White Vinegar, Coke, Ginger ale, Glass cleaner, Lemonade, Tea or iced team, Apple Juice and rubbing alcohol __**Hypothesis**__ I think that sugar will dissolve the fastest in all of them because sugar is softer or more breakable, When salt is more solid and more like a Crystal than sugar. __**Equipment**__ Sugar Salt Teaspoon x2 White vinegar Sparkling water Ginger ale Glass cleaner Lemonade <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">Ice tea or Tea <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">Apple juice <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">Stop watch <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">(50mil) cups or containers <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">__**Method**__ <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">1) Get all you need (equipment) to do your experiments. <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">2) Get two of your (50ml) containers and fill them up with the same liquid. <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">3) Get a partner and you both need to have in 1 hand, a timer and in your partners hand a teaspoon of sugar and in your other hand a teaspoon of salt. <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">4) Poor both sugar and salt in a the same time then start your stopwatches at the same time and stir continuously at the same speed. <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">5) Remember to chart up the time on to your chart. <span style="background-color: transparent; color: #000000; font-family: serif; font-size: 16px; text-align: start; text-decoration: none; vertical-align: baseline;">6) Once done poor out liquid and put in a different one, then repeat with other liquids.
