Reflections on Enrich 2011

Sherbet

Today in our Science Talent Development, we were doing some baking. We made bread, sherbet and hokey pokey. Some of the chemical reactions we were looking at was what the baking soda did to the hokey pokey. The baking soda made it rise. In the bread we put yeast in which made the bread rise as well. These two ingredients are called Rising Agents. Just before we started making the sherbet we had to taste all the ingredients that were going to go into it:
Icing Sugar
Raro
Baking Soda
Tartaric Acid (TA)
Citric Acid (CA)
Then we wrote down what they tasted like. The one with the best taste was the icing sugar and raro. Then there were the two sour ones, the Tartaric Acid and the Citric Acid. The one that tasted the worst was the Baking Soda! Disgusting!

Science

Today in science we were making Lava Lamps. It was so fun. I am going to share what I learnt with you and show you how to make them. 
You will need:
Oil
Water
Food colouring
Berrocca
An empty bottle


What you need to do:
Fill bottle with water about quarter full. Then put oil in another quarter full. After you've done that drop 12 drops of food colouring in. Then get 2 Berroccas and put  them in.  The Berrocca contains citric acid and baking soda.  This reacts with the water.  The bubbles take hold of the food colouring, and make them float up to the oil, which has settled on the top.
That is how you make a Lava Lamp.

Habits of Mind Session 3

Today in Habits of mind we paired up and had to write a story, put on a play or write a poem about a Habit of Mind. I paired up with Stephen and he and I wrote a story about Striving for Accuracy. Striving for Accuracy is when you try your best and care what score you get in a test or something. Then we put it into a movie on photo booth. We had to make the play, poem or story sound like the Habit of Mind was a person.

Melting Moments

Today in our science Talent Development we were getting into working with solids, liquids and gases.
We did two experiments. These were called Melting Moments A and Melting Moments B. Melting Moments A was when we divided into three groups, two groups of four and one group of five. We needed one plain water ice cube, one sugary water ice cube, one powdered raro ice cube 3 petri dishes and one stop watch. We were going to see which ice cube would melt the fastest. We all wrote down our hypothesises. My hypothesis was that the sugary ice cube would melt first.  After that we got our ice cubes and put them in a petri dish each and labelled them. Then somebody started a stop watch and we watched our ice cubes for 3 minutes. So far the the plain ice cube was 3rd, the sugar ice cube was 1st and the raro ice cube, 2nd. Then we waited another 3 minutes. By that time, the water had melted the most, the sugar hadn't made progress and the raro was still in 2nd place. Then at the 9 minute mark the it was still the same. Then, at the 12 minute mark it turned out the water won! Our next experiment was Melting Moments B. For that we needed three plain water ice cubes, 3 petri dishes, sugar, salt a teaspoon  and a stopwatch. We were going to see which ice cube would melt the fastest: the one with sugar on top, the one with salt or the plain one. Once again, we wrote down our hypothesises. I thought that the plain one would melt first. What we had to do was get the ice cubes and put them in a petri dish each. Then we just did the same thing as the first experiment. In the end it turned out that the ice cube sprinkled with salt melted the fastest.  The reason is because salt changes the freezing point of ice. I can't wait to do our next experiments!
