Coke And Mentos

Aim - I want to find out what will happen when you drop Mentos into a bottle of coke

Method

Equipment

- Mentos

- A bottle of coke

- Flat surface

Instructions 

1. Get your equipment

2. Take the lid of the coke

3. Put your bottle of coke on a flat surface

4. Put the mentos into the coke and sees what happenes

Result

Here is a video of someone doing a coke and mentos experiment. LINK 

Conclusion
I can conclude that if you add mentos into a bottle of coke It will make the coke erupt and shoot out of the bottle. 
Discussion

As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide that is still dissolved in the soda to cause more carbon dioxide to be freed and create even more bubbles, resulting it to erupt. 

What is a base?

 Acid has Hydrogen in it.

The strength of Acid is measured on the pH scale.

It goes from 0 to 14 

0-1 red

2-3 orange

4-6 Yellow

7 Green

8-10 Blue 

11-12 Indigo

13-14 Violet 

A base is an opposite chemical to an acid 

A base contains hydroxide (OH)

An acid and a base NEUTRALISE each other and make water 

Here is a photo of what it's like.

 Hello everybody today I am going to be telling you about our reading activities for this week.

So we practically have to do the same thing as last week but a different subject. The subject that we are reading about Is gold mining I don't know much about mining soooo. yeah, but I didn't know that they did mining in NZ.

We have to read a journal and look at other resources as well and then I have to take a screencastify of me reading the journal and the thing we have to focus on while reading is that we have to try correcting ourselves while reading out loud. Here is a screencastify of me reading our journal.
