Fermentation

Results:

Before -->

 After -->  

It tasted really disgusting. It tasted sour at first but then it tasted bitter. It smelt like barf and rotten drinks. It look like lemonade but don't let it's looks deceive you. The sweet taste disappeared compared to before i left it out.

Discussion:

What is fermentation? 

Fermentation is like brewing. It's a process in which the sugar breakdown into alcohol. The yeast eats the sugar and releases carbon dioxide and alcohol.

What is the difference between beer, cider, wine, vodka and whiskey?

They all have different sources of sugars that get fermented. For example, cider's source of sugar is apple, vodka's source of sugar is potato.

Red Cabbage Indicator

 Aim:

I want to find out how red cabbage can tell if a liquid is an acid or base.

Research:

Method:

Equipment:

• Beaker
• Red Cabbage
• hydrochloric acid (the acid)
• sodium hydroxide ( the base)
• Something to mix with. (we used a dropper)
• Boiling water.
• Test tube. 

Instructions:

1. Get all your equipment
2. Wash your hands.
3. Pour boiling water into a big beaker.
4. Rip the red cabbage into little pieces.
5. Add the bits of red cabbage into the beaker.
6. Mix the red cabbage with the boiling water until it becomes a dark colour. (we used a dropper to mix it together)
7. After mixing, with a dropper, add about 10 drops of the red cabbage juice into each of the big test tubes.
8. Add 10 drops of the acid on one of the test tubes and add 10 of the base to the other test tube.
9. The test tube that has only acid on it and the test tube that only has the base in it are the full colours if you only add acid or base.
10. Experiment with the red cabbage, the acid and the base. Add as many drops to make different colours.

Results:

Discussion: 

What is an acid and a base? 

An acid is a substance that contains a lot of hydrogen ions. Hydrogen ions is when a hydrogen atom loses or gains an electron. A base is a substance that has a lot of hydroxide ions. Hydroxide ions is when oxygen and hydrogen atoms it is held together by one pair of electron. Acid can give protons to base. And base can accept protons given from the acid.

What do chemical indicators do?

Chemical indicators gives a visible sign to represent what substance it has. The visible sign is the liquid changing colours.

Making Sherbet🍧🍨🥄

Hello everyone. One tuesday we tried to make sherbet. Here is what we did:

Aim: 

I want to find out how to make sherbet.

Research:

How to make sherbet:

Sherbet

Method:

Equipment:

• Citric Acid
• Raro
• Baking Soda
• Tartaric acid
• Paper

Instructions:

1. Wash your hands
2. Get all required equipments
3. Place the paper on your table.
4. In piles, separate the 3 powders
5. Using your popsicle stick, mix some of each powder.
6. Taste the sherbet.
7. IF there is to much baking soda, add more citric acid.
8. If there is too much citric acid, add more baking soda.
9. If the flavour tastes bitter and sour add more Raro to balance the taste.

Results:

It tasted sour at first but i liked it sour. I had more fizz in my sherbet than taste. I liked adding more raro than fizz so it tasted more like Raro than sherbet.

Discussion:

Why did the sherbet not foam on the paper but it did in your mouth? 

Citric acid and baking soda some atoms contained into these powders turn into carbon dioxide. As the gas escapes the sherbet starts to bubble up in water or your mouth.

What was the chemical reaction in the sherbet?

The foam was caused by the liquids in your mouth which reacted to the carbon dioxide mixed into sherbet.

What type of chemical reaction is this?

Neutralization.

Eating Hot chilli 🌶🌶🔥🔥🔥🔥

Aim: I want to find out how to get rid of burning chilli off my tongue.

Research: 

Method:

Equipment

• Fizzy
• Milk
• Water
• Popsicle stick
• Chili sauce (carolina reaper)
• cup
• Timer

Instructions

1. Get all required equipments.
2. Scoop some chilli onto your stick.
3. Start the timer and eat the chilli
4. Stop the timer after 4 mins.
5. Rate how hot your mouth has become.
6. Do the experiment again but drink water after 2 minutes.
7. Do experiment again but drink coca-cola poured into a cup after 2 minutes.
8. Do experiment again but drink milk after 2 minutes.

Results:

The first time I had chilli, It was burning my mouth. I had it without any liquid score 10.

The second time I tried the chilli I did it with water, I rate it a 10 

The third time I did tried the chilli I did it with coca cola, it made it made worse, I rate it 11

The fourth time I tried the chilli I did it with milk, I rate it a 4

Discussion:

Why does chilli burn your mouth?

A chilli has this oil-based molecule called capsaicin. It gets released to your saliva and bins onto the receptors in your mouth and tongue. Which then triggers the receptors to send signals to your brain, thinking you are currently burning.

Why did the milk reduce the burn?

Milk mostly contains casein, which i learnt in the plastic milk experiment. The casein helps wash off the capsaicin in your tongue or mouth. Think of it like soap washing off grease.

Measuring Mentos ad Coke 🌋 🥤

HEllo everyone.

This week in Science, Chemistry we are trying to experiment with coke and mentos. Here is what we are working on.

Aim: I want to find out how many bubble are made when mentos is dropped in coke.

Method:

    Equipment: 

• Coke, Coke Zero, Sprite
• Mentos
• Measuring cylinder, 100 ml & 10 ml
• Small beaker
• Safety Glasses
• Liquid Soap/Detergent

Instructions:

1. Get all required equipments.
2. Wear safety glasses
3. Pour 20 ml of coke into the 100ml measuring cylinder.
4. Add 5 ml of the detergent in to the 100 ml measuring cylinder with the coke.
5. Add the mentos.
6. Wait for the fizz to happen.
7. Measure the height of where the bubbles end up.

Results:

	Coke	Coke Zero	Sprite
Height of bubbles	45 mL	35 mL	40 mL

Conclusion

I found out that if you add detergent to the mentos and coke experiment the bubbles stay on its same place.

I also found out that the sprite is more effective than coke and coke zero even though coke was the highest because we didn't add the equal amount of each fizzy.

What is casein? 

Casein which is a latin word which means 'cheese' is a protein also found in other dairy products. This is why casein might be considered as a dairy product. When milk is heated and combined with acid such as vinegar the casein molecules reorganize into a long chain. The substance it ends up into is the same as  plastic and which involves with this experiment.

Skittle Colours 🍬🌈

Hello everyone this week in science, chemistry we have been experimenting with sweets. Here is what experiment we are trying to do.

 Aim:

I want to find out what happens when put skittle in water.

Method:

    

    Equipment

• Petri Dish
• Skittles
• Warm water
• Beaker

Instructions

1. Get all required equipment
2. spread out your skittles around the edge
3. Gently, pour the warm water into the center of the petri dish.
4. Observe the next results of what happens.

Results:

Discussion:

Why did the colours leave the skittles?

The hard sugar coat around the skittles dissolves faster when on warm water. 

The colouring in the sugar drags around the hot water and makes the colorful mixture.

Why did the colours not mix?

Each skittle has different kind of flavours which is  density meaning that one colour can't mix because of their differences of how much density it has so some colours are in different levels of the water.
