The great pacific garbage patch

Hello, in social studies we have been learning about the great pacific garbage patch and the causes and effects, I made a news article about it. it includes phytoplankton, mocroplastics and other thing can that help, or harm the ocean. Here is the news article I made




Reading & Reflection

Hello, the past 2 weeks we have been reading in wananga, I read Gangsta Granny by David Walliams. It's about a little boy and his grandma, he doesnt like going to her house on friday because she smells like cabbage and only likes playing scrabble, one day over the phone to his parents he said she is boring and smells like cabbage. 

Granny heard him say that and so she changed, she bought fake jewels to make Ben think she was a gangsta, then she was going to pretend to steal the Queen's crown jewels, but Ben insisted he wanted to go, to the point that she couldn't say no, then Ben made a good plan to steal the crown jewels, by going through a sewage pipe into the Queens house. When they went through with that plan, they went into the sewage pipes and when in there, they had successfully got to the crown jewels then the Queen showed up, they wouldve got in alot of trouble, but luckily the Queen pardoned them and let them go.

Environment issues

Environment Issues 

Over the past few weeks we have been learning about the earth and environments. Lately around the world there have been a lot of environment and ocean issues, including water pollution, litter, the extinction of animals, or even just endangered animals being killed. Or even Just volcanic eruptions going into the ocean killing turtles and fish. 

Over the few weeks we have been learning about this, I have learned that if we do not stop littering and actually start cleaning the ocean, in 30 years the ocean will be 50% fish and 50% plastic. i have also learned that at a beach. also about Phytoplankton, Phytoplankton is a micro organism that consumed carbon dioxide and makes 4 times more oxygen than the amazon rain forest. in a movie called Seaspiracy there are a lot of dead whales found on a beach, and most of the whales had plastic bags inside them, but one of them had 30 inside it.

Metal Reactions.

 Metal + Acid

Equation - Metal + Acid >>> metal salt + hydrogen

Method - Get a splint and light a Bunsen burner, then you need to get 2ml of Sulfuric acid and put it in a test tube, then put a small piece of metal in the test tube, the metal will dissolve and the test tube will heat up, after that you need to put a boiling tube on top of the test tube and put the test tube inside, wait 1 minute and light the split. then with the splint you need to lift up the big boiling tube, keep it upside down, and put the splint inside the boiling tube, it will make whistle or pop sound.

When we had done the steps to make the whistle, Cody put the splint inside the boiling tube and it made a very loud whistle sound. this experiment was fun because there wasn't a lot to do, but the stuff we had to do was easy. if we were to do this experiment i would like to add more acid and a lot more metal to try and make the sound pop / whistle as loud as possible.



Making a Metal Oxide

Method - Light your Bunsen burner, Hold the piece of magnesium in the scissor tongs but make sure you are holding the very end of the magnesium piece. hold the magnesium over the fire for about 3 seconds in the middle of the flame, not the top, not the bottom, directly in the middle, it should light on fire, that's when you should look away, and just look at it from the corner of your eye, if you look directly into it, it  can permanently damage your eyes.

Testing for the presence of Oxygen

Method - Light the Bunsen burner and add the manganese dioxide to the boiling test tube, add 2 millilitres of hydrogen peroxide. then what you need to do it light the splint for a few seconds and blow it out, the splint will still be hot and glowing, then you need to put the splint in the test tube, not in the hydrogen peroxide but in the middle, and the splint will relight


Metal Carbonate + Acid >>>>>> Metal Salt + Water + Carbon Dioxide
                                      CaCO3          2Ha                 CaA2            H2O            CO2

Equipment - Two Boiling tubes, Delivery Tube and Bung, Bunsen Burner, Test Tube rack, Wooden Splint, a bottle of acid, Small amount of metal carbonate, Test tube tongs, Safety Glasses.

Method - Light your Bunsen Burner and add a tiny pea sized amount of  metal carbonate into one of the boiling tubes, place this boiling tube into a test tube rack, make sure you have the bung and delivery tube ready. add 5ml of acid to the boiling tube, hold the other boiling tube with the tongs and capture the gas, when you think the tube is full your lab partner will light a wooden splint, then put the splint into the test tube and see what happens.

DTE Reflection Blog Post

DTE Reflection Blog Post

For the past few weeks we have been making a slide show about Encryption methods & Techniques, there are many ways to encrypt or decrypt a message. I've made a slideshow on how to decrypt a message and the methods you can use, the first three are easy, second 3 are medium and the last 3 are the hard ones to learn. There is also a website called discover crypt, this is the website I've been using to learn about all of these methods. Discover Crypt


Easy: Pig Pen, Caesar Cypher, Simple Transposition.

Medium: Rail Fence, Atbash Cipher, Polybius Square Cipher

Hard: Columnar Transposition, Viginere Cipher, Bifid Cipher.

Ive added a description and a photo of the table you use to decrypt/encrypt messages.
