Homemade Solar Heaters

Aim= Our aim was to plan,create and test a homemade solar panel. Not only that but our aim was                  also to  use our solar heater that we had created to heat up some water and find out the                        temperature using a thermometer

Method= First we planned a design that we thought could heat water. the teacher then showed us what design we were going to be creating. we then did a paper mache balloon and left it to sit for a few days. we then popped the balloon and cut the paper sphere in half. we then wrapped the inside of the half circle in tin foil so that you couldn't see any paper on the inside. we then filled up a beaker with water and put it in the inside then left it out in the sun to heat up. we then measured the water to find the results.

Results= In the end the air temperature was 24 degrees and we heated up the water to 37 degrees which is a 13 degrees difference  so i would say it worked.

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.

The Strength of roots

For the past week we have been reading the strength of roots by Marisa Maepu  and For this book I decided to create a stop motion of what the story was about but here is a small explanation of what happens in the story.

A boy was walking around in the forest in Samoa when the ground began to shake but after that he started to head back home but before he could he got knocked over by a tsunami and as he was in the tsunami he managed to hold onto a big tree.After that he woke up jammed between branches of a big tree and he was at the top. He looked down to see rescuers but couldn’t speak because of the salt water he swallowed. Finally a branch snaps and a rescuer finds him and gets him down and helps him but then he leaves to find his family. Here is the stop motion that I created.

Stop Motion

Fo Guang Shan Temple Visit

On Tuesday the 21st of may All of the Year 7s at HHS went to the Fo Guang Shan Temple And it was a lot of fun. First off we got split into two groups and then we peacefully walked into the art gallery so the could talk to us about 3G 4G which means 3 goodness and 4 givings and the three goodness is good deeds,good words and good thoughts and that is the 3G and the 4G is  Give hope,Give joy,Give confidence and Give convenience. After that the two groups split up and my group went up stairs into the hallway of Time that led us to the library that was really small and was filled with books of all different languages and the Guide talked to us about some stuff and then we headed back down the stairs and back outside where we started and we all lined up to get water tattoos on our hands.After that we switched with the other group and we got to do what they were doing before which was, we were making a lotus flower which like a Lilly pad which pretty white flower with pink tips and then on the bottom we added a rubber band so we can wear it in our hair or on our wrists. Once we had finished making our beautiful flowers we headed outside where they provided biscuits and water. Once we had finished our delicious snack we went back upstairs and went into this big golden room and in surprise the police were there they did there scene and then they picked some people to get dressed up as police after that the police left and then our Gide took us through the journey of meditation and that was the most peaceful and silent time of the whole trip. after the peaceful meditation our Gide showed us a short film about prince Siddhartha and how he become Buddha. After that we headed out to the buses and the journey was over .
