Ruaumoko Rages Book Review.

Title of the Book - Ruaumoko Rages 

Author - Bronwen Wall

I rated this book a 3/5 stars because it isn't the kind of book that I would choose to read, but I did read it and i did learn a lot. I learnt about the different types of volcanoes. The stratocone The Lava dome and the Caldera. My favourite part is when they told me about all of the different volcanoes in NZ. THERE ARE HEAPS. You should read this because it is an interesting book, and I learnt a lot. I think that if you like learning something new and you like volcanos then you will like this book.

 

Volcano Animation!

In team toroa we have been learning about natural disasters. In reading we have been learning about volcanoes. My animation below is how a volcano erupts and some questions I had about volcanos that I have now answered! I enjoyed learning about volcanic eruptions and how interesting they are! Did you know that there are three different types of volcanoes? A stratocone volcano, a dome volcano and a caldera! I found it easy to learn the process of how an eruption is caused. It was a bit scary at first, big lava shooting cannons all over the world, but now I think that it is cool and interesting. I found it hard to make the lava inside of the earthquake look kinda good, but it was very hard to just do it with polyline so I went with the option of just a big blob of red orange and yellow. Next time I will put more effort into my polylining, and make it look more realistic.

Cool Lava Lamp Experiment!

In science elective we did a cool lava lamp experiment. How did that turn out?  The oil stayed above the water because the oil is less dense than water. The oil and water do not mix because of “intermolecular polarity.” Molecular polarity basically means that water molecules are attracted to other water molecules. They get along fine, and can loosely bond together. This is kind of like when magnets are attracted to each other. Oil molecules are attracted to other oil molecules, they get along fine as well. But the structures of the two molecules do not allow them to come together. When you added the tablet piece, (aspirin) it sank to the bottom and started dissolving and creating a gas. As the gas bubbles rose, they took some of the colored water with them. When the blob of water reached the top, the gas escaped and down went the water. If we shone a torch light through the cup, it made a nice glow making a lava lamp! All you need for this experiment is some water, (If you want you can put some food colouring in it) some cooking oil and one aspirin tablet.

Cool Bath Bomb Experiment!

 In our science elective, we learnt how to make bath bombs for mothers day. But how do bath bombs react? When a bath bomb comes in contact with water, the baking soda and citric acid react to make carbon dioxide bubbles. This is an acid–base reaction, where baking soda (also called sodium bicarbonate) is a weak base and citric acid is a weak acid. We had lots of fun making our bath bombs, and my mum loved hers! Here are some photos on how they turned out below!. Here is the recipe for the bath bombs if you would like to make them yourself!

Bath Bomb Recipe What you will need: (dry) - 1 cup of baking soda 1/2 cup of citric acid  1/2 cup of epsom salt (or any salt but epson is best) (wet) - 1 tsp of water 1 tsp of essential oil 3 tsp of olive oil / coconut oil / Almond oil 2-3 drops of food coloring  Measure out and whisk together your dry ingredients in a large bowl. Next, in a small cup, mix together the wet ingredients. This is also where you’ll add the essential oils.  The next step is very important. Add the wet ingredients to the dry ingredients. You’ll want to do this very slowly, adding little drops at a time while mixing. The citric acid is what causes the bath bombs to fizz when it comes into contact with water. Adding the wet ingredients slowly minimizes this affect. Then, firmly press the mixture into the mould.  Let the bath bombs dry for at least 24 hours.

Awesome Earthquake Animation By Toby And Ceejay!

In team Toroa we have been learning about earthquakes. Our task this week was to create something on google. Ceejay and I decided to make a animation about earthquakes. I found it hard to get the effect of the shaking look good. We went with the idea to take a screenie and make it shake, but it ended up looking blurry. But its okay. Nothing is perfect. I found it easy to polyline our city called Pensilvile. We added four buildings. My favourite one was the toaster oven shop. I enjoyed working with my mate Ceejay to do this animation. We did start goofing off at some points but we got it finished in the end. Next time I will try not to goof off with Ceejay. We started to get off task a couple of times. We also took a wile to make the city's buildings. But it was fun.
