Foaming and Fizzing

Kia ora bloggers,
I'm back with a new blogpost. This term our schools focus is Up, up and away. At the start of the week my class did an experiment called foaming and fizzing. We had to taste the vinegar and baking soda separately and we also had to taste it when the vinegar and baking soda were mixed together. Once we had done the experiment we had to write a report on the experiment. Here is the report:

B E G I N N I N G	TITLE	Yuck and Yum!
	QUESTION.	If we mix vinegar and baking soda together will we observe some kind of reaction?
	THESIS.	Vinegar tastes sour and it is a liquid. Baking soda is a solid, soft white powder and it tastes salty and horrible. They are both food substances but based on their different taste, they must be chemically different. So, if they are mixed together, there might be a chemical reaction.
	HYPOTHESIS.	We predict that when we mix vinegar with baking soda an observable reaction will occur. We might see and hear an explosion, fire, foaming, bubbles, fizzing or something else. The resulting mixture might look or taste different. There might even be a difference in the size of the materials.

M I D D L E	EQUIPMENT AND MATERIALS:	Baking soda Vinegar Container for mixing Teaspoon for mixing
	PROCEDURE	Step 1: Pour some vinegar into a container to a depth of about 2cm. Step 2: Use a teaspoon to measure in half a teaspoon of baking soda. Step 3: Mix with a teaspoon. Step 4: Observe and record what happens.
	OBSERVATIONS:	At step 2 the mixture started to fizz. A fizzing sound was heard, bubbles were seen to appear in the mixture and the materials rose higher in the container. At step 3, when the materials were mixed, even more bubbles appeared and the volume of the materials in the container rose even higher. When the mixture was tasted, the taste was unpleasant and it was similar to the baking soda.

ANALYSIS AND CONCLUSION

The goal of this experiment was to see if an observable reaction would take place when vinegar and baking soda were mixed together. The result of our experiment prove that our hypothesis was correct. We predicted that there would be an observable reaction, and there was. There was lots of foaming and fizzing happening and bubbles appeared which means a gas must have been produced. A quick check online showed us that the gas was carbon dioxide.

The last week

Hola, or should I say adios?
This is the last blog post for Term 2.

I have had an amazing term learning about animals, doing new things and fantastic art. I would love to say all the things I did, but that would take too long. So instead, I made a little presentation that shows some of my work.

Zoofari

This week we went to the Auckland zoo on a Zoofari. We slept in the old elephant house where the elephants Burma and Kashin used to sleep. Here is a photo of a kukupa/kereru on Mrs B's head.

I am working on a report about servals and I saw one  but it was too quick to get a photo. It looked just the way I thought it would.Here is a photo of a tiger.

My Serval Thinglink

Hello bloggers!!! This term our school is focusing on all creatures great and small... So our class did animal reports. I did mine about a serval. I used a Thinglink to present my work.

Argument writing

Kia ora bloggers! For the past two weeks our class has been writing arguments for the speech contest. I wrote one with a buddy. My buddy was Lilly. Together we wrote an argument about why zoos are good. Sadly when it came to judging we didn't get chosen to go to Kaikohe. Instead Willow and Depla are going to Kaikohe. Here is my argument:

Why zoos are good

Have you ever been to a zoo? A zoo is a place where humans hold animals in separate enclosures so none of them will get hurt by each other and so humans can can come and see them. Well, I believe that zoos are good. Here are some reasons why.

Firstly, a zoo is like a sanctuary for sick or injured animals just like a hospital. Zoos have great vets to look after the animals. If you were an animal living at the zoo you would know you were going to be looked after. If the animals were in the wild they would die of sickness because there are no vets in the wild. Also, after the zoo vets have healed an animal, sometimes they release them back into the wild.

Secondly, they have breeding programs for endangered animals to increase their family. So none of the animals will be extinct. If the animals were in the wild it would be harder to find a mate to breed with. We need more zoos in the world to save exotic species. For example there are only 7,100 cheetahs left in the world. We need to save animals and  not let poachers keep on killing them.

Finally, zoos educate people about the beauty of animals. Every person should know about animals so they respect them ,understand them and don’t hurt them. And everyone knows if you want to know more about animals, you just go to a zoo.

So, I sure hope you agree with me that zoos are good because they are safe places for animals, they help bring more endangered animals into the world and they teach us all about our planet’s greatest treasure-the amazing life forms that live on our earth. C’mon people, let’s look after our zoos and help them look after the animals.
