Blobs In A Bottle.

Blobs In A Bottle
You Probably Wondering What I Mean By Blobs In A Bottle

These Are The Ingredients :

Blobs in a Bottle         

Resources:

• A clean 1 litre clear soft drink bottle

• 3/4 cup of water                   

• Vegetable oil

• Antacid tablets (such as Quick-Eze or Mylanta)

• Food colouring

Procedure:

1. Pour the water into the bottle.
2. Use a measuring cup to slowly pour the vegetable oil into the bottle until it’s almost full. You may have to wait a few minutes for the oil and water to separate.
3. Add 10 drops of food colouring to the bottle; the drops will pass through the oil and then mix with the water below.
4. Break an antacid tablet in half and drop it into the bottle. Watch it sink to the bottom and watch the lava start to flow.
5. To keep the effect going, just add another piece of antacid tablet.

Big questions:

1. Does the temperature of the water affect the reaction?
2. Does the effect still work if the cap is put on the bottle?
3. Does the size of the tablet pieces affect the number of blobs created?
4. What is an oil spill and how do they happen?
5. How do ice and water interact during an oil spill?
6. How does oil affect marine life during an oil spill?

Scientific Explanation (How it works):

To begin, the oil stays above the water because the oil is lighter than the water or, more specifically, less dense than water. The oil and water do not mix because of something called “intermolecular polarity.” Molecular polarity basically means that water molecules are attracted to other water molecules. They get along fine, and can loosely bond together (drops.) This is similar to magnets that are attracted to each other. Oil molecules are attracted to other oil molecules. When you added the tablet piece, it sank to the bottom and started dissolving and creating a gas. As the gas bubbles rose, they took some of the coloured water with them. When the blob of water reached the top, the gas escaped and down went the water

THIS IS ME!!! (Student Profile) 2018

This Is Me

Hi There my name is Levi and I am half Maori and Half NZ European and I am 12 years old and I am a Year 7, I also have one sister and I have attended at Hornby High School with my sister and my friends.

And this year 7 I met a new teacher called Miss Allan and she is a pretty good teacher she teaches us cool things and things that we have to do in life later on when we are older. So she teaches us stuff like to keep our environment safe and respect the things at our school like the new school that they have recently built.

So about me I like to play Rugby League,Basketball,Cricket and I like to watch people drift and do cool stunts in cars or on motorcycles but it i kinda funny when they fall off.

7al Learning Hui

Today My Class Hosted a Hui - Basically An Assembly And I Was Apart Of A Couple Things You'll See.

So for our Learning Hui i was one of the I.T people and I was apart of a play called Chicken Little.

The people in the play were Me-Levi, Rieya, Skyler, Callum, Tyler And Hope and the things they were playing were

Callum - Turkey Lurkey And Henny Penny
Levi - Ducky Lucky
Rieya - Chicken Little
Skyler - Narrator
Tyler - Foxy Loxy
Hope - Goosey Loosey

So the play went very good and at The End Foxy Loxy ate everyone except Chicken Little because she got away pretty fast but everyone else got gobbled up inside on Foxy Loxy's stomach.

We had a few difficulties but we got there in the end hope you enjoyed this blogpost

THE END
This Is The Slide That Me, Kody, Callum And Tyler Done
