Making Fizzy Drink

Aim=Our aim was to make a fizzy drink.

Ingredients & Equipment=Cup,spoon,citric/tartaric acid,baking soda,Raro/ flavoring ,Water.

Method=First off we took a spoon and cup and started to pour in our citric acid,baking soda, Raro and then filled the cup up with water and then we had our fizzy drink.

Results= When we added the water it bubbled over the top and it was exploding little drips of water everywhere.when we tasted it it had a slight taste of orange raro but then it slowly turned into a citric taste kind of like fizzy lollies without flavor. what was worse was the after taste it lingered in your mouth for ages and it tasted SO bad.But it all depended on how much baking and citric acid i actually put in it.

Conclusion= It tasted bad because the baking soda and the citric acid over powered the flavoring and the baking soda made it salty, bitter taste overpowering every other flavor. The baking soda and the citric acid created carbon dioxide in the water making it grow / make bubbles. The citric acid  was an acid and the baking soda is a base and that means that the base plus the acid = CO2

Enzymes

For science today Me and Ella were learning about Enzymes by doing an experiment including jelly.



Aim= What are Enzymes and what they do to the jelly

Ingredients & Materials= Small tray  X2  ,Mashed and skinless kiwi fruit , jelly w/                                                                         boiling water.

Method= first we cut all the skin off of the kiwi fruit. Second we took the kiwi fruit and mashed it up. Next we spread the mashed kiwi fruit on the tray evenly. After that we poured the jelly into one of the trays that does not have kiwi fruit in and poured jelly in the one that did have kiwi fruit in.

What is a enzyme?= A enzyme is a substance produced by a living organism Which acts as a catalyst to bring out specific biochemical reaction . in other words  Enzymes can build or brake down other molecules. The molecules they act on are called substrates. Enzymes are catalysts - Chemicals that hasten a chemical reaction without undergoing any change themselves. Most enzymes are huge protein molecules.

Chromatography With Skittles And Felt Pen

Last Tuesday we did an experiment around chromatography and the experiment that we did was using colors and put it in liquids and then see what happens to the colors.

Felt Pens 

Aim=Our aim was to see on the filter paper what the liquid would do to the colors and what colors made the color that we were using.


Materials & ingredients= Type of liquid, Filter Paper,Felt pens,Beaker


Method = First off we took a colored felt pen then put a dot on the bottom of the filtered paper that we had cut out into rectangles.   We then poured our liquid into a beaker and dipped the filter paper with the dot on in.    When you put the filter paper in the liquid you want to make sure that the colored dot didn't touch the water  because then it wouldn't work.    After we put the filer paper in the water we held  it there for a couple of minuets and then we watched what happened.


Result= in the end the liquid rose through the filter paper and stretched the color out revealing different colors and it looked really cool.


















Skittles


Aim= Our aim was to see what happened to the skittles when we let them soak in the water.


Materials & Ingredients= Circular Tray (with lid ),Water,Skittles


Method= First we placed the skittles in the tray evenly spaced then carefully poured the water in. then put on the lid and watch what happens.


Result= In the end the tray looked like a color wheel because the color soaked into the water but stayed in their own section so the colors didn't mix. since all the colors disintegrated into the water it left the skittles white and colorless.


You can see the skittles starting to lose color round the edges 


















Red Cabbage Indercator


Red Cabbage Indicator 

    
   Aim =    This Science lesson we were trying to use Red cabbage as a PH indicator



    PH levels = The PH levels show in colors to see which house hold items are most acidic.here                                     is a table of the colors of PH levels.


    Materials & Ingredients = Red Cabbage , Knife , Boiling Water ,Filter Paper , One                                                                           large glass beaker , Baking Soda , Washing Soda ,                                                                                     Lemon Juice , Vinegar ,Cream of tartar , Antacids ,                                                                                   Seltzer Water , Muriatic Acid and Lye , 
                                                                         House Hold Items To Test.

   Method = First we set up our Bunsen burner the put the cabbage in the beaker and boiled it                                      into a liquid, Then we filtered the liquid and poured it evenly into test tubes.

                              Next we started to add in our house hold items into the liquid in the test tubes then                                   all of a sudden the started to change colors.


Hypothesis = In simpler worlds the cabbage changed the color of other liquids because of the                                       acids in the other liquids so the most acidic color would be Yellowish greenish at                                     the PH level of 12 . And the least acidic color would be red with the PH level of                                      2 .

Results = In the end these were the house hold items= Sodiumhydrox , Toothpaste , Toilet                                     Cleaner , Lemonade , floor Cleaner , Shampoo.
