Making ginger Beer 🍺

Kia Ora Readers!

Today in science we learn't how to make ginger beer with ginger. We firstly did the blogpost and then on the next lesson we made the ginger beer. 

 Aim: I want to know how to brew ginger beer.

Research:                 

Method:

Equipment:

• Ginger (source of sugar)
• lemon
• Warm water
• Yeast
• Cup
• Spoon/popsicle stick

Instructions:

1. Wash your hands thoroughly with water and soap.
2. Get all of the equipment required. 
3. Cut up/ mince 1 tablespoon of ginger.
4. Put 1 tablespoon of ginger into the cup.
5. Fill the cup half way with warm water.
6. Add 1 teaspoon of yeast into the cup of ginger and water.
7. Mix the mixture together with a spoon.
8. Leave the ginger beer mixture to ferment for 6 days or as long as you want.
9. After 6 days you can finally drink it and taste test it. 

Results:

Before --------> 

 After ------> 

Disscussion:

Sugar

• Potato = Vodka ( Leave for 3 to 5 days) 
• Rye =  Whiskey ( Leave for 5 to 10 days)
• Apples = Cider ( Leave for 5 to 14 days)
• Grapes =  Wine ( Leave for 3 to 4 weeks)
• Hops = beer ( Leave for 2 to 4 months, 6 to 10 hours hand brewing)

What is fermentation?

 

Fermentation is when yeast eats the sugar and excretes carbon dioxide and alcohol.

What are the best conditions of brewing?

Making sure the alcohol is at a cool temperature by chilling the drink, not shaking the drink so that the surface area doesn't get increased etc.

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

Liquor drinks such as vodka, whiskey and brandy are called "distilled alcoholic beverages."  Drinks like these will be more alcoholic proof. The opposite of this is " undistilled alcoholic beverages"  these drinks include less alcohol like beer, champagne, port, sherry and cider.

Tasting the ginger beer:

 My ginger tasted absolutely disgusting. For me it was a big fail. It tasted very watery and tasteless. I think I didn't add enough ginger, lemon and sugar. It lost it sweetness and became gross. It smelt very strong.  

A Healthy menu for a week ⚕️

 Kia Ora Readers!

This week in health we have been learning what a healthy meal is and what is in a healthy meal. We watched a video about a lady explain how most teenagers in Australia aren't eating healthy meals.  I learnt that eating un healthy young may lead to problems in the future. So my teacher set us a task to create a healthy menu for a week. This task was very fun to do because I love making slideshows and sharing my ideas. The hardest part was finding out what is healthy to eat, nutritious and delicious. My favourite part was making the slideshow unique to me.

What would a healthy meal look like to you??

Red Cabbage Indicator 🎨

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

Research: 

Method:

Equipment:

• Acid - Hydrochloric acid
• Base - Sodium Hydroxide
• Red Cabbage
• Water
• Cup/Beaker
• Test tube
• Dropper

Instructions:

1. Wash your hands.
2. Get all of your equipment required.
3. Add water to your cup/beaker.
4. Break the cabbage into small pieces.
5. Mix the red cabbage and water together with the dropper until it starts to turn dark purple. ( The darker the water the better the colours will be)
6.  With the dropper add three drops of the purple water to each test tube.
7. For the first time just add the acid to one of the test tubes and base to another.
8. Gradually add the base and acid to each test tube. 
9. Add as many drops of acid and base to create colours. (Make sure you don't get any of the acid or base on your hands).
10.  Maybe even try to layer the colours on top of each other.

Results:

Discussion: 

Q1 : What is an Acid and a Base?

  A1 :  Acid is a substance that gives hydrogen ion and donates to a substance. When the acid is added to the cabbage water it creates a pigment and changes the colour. Base is a substance that takes the acid. 

 

                    

 Q2 : What do chemical indicators do?

 

  A2: The Chemical indicators creates the chemical reaction. Which makes the colour appear when the acid and base is included in the cabbage water. 

Making sherbet🍬

 Aim:

 I want to find out how to make sherbet.

Research: 

                                                             How to make sherbet:

The science of sherbet:

Method:

Equipment:

• Citric acid/tartaric acid
• Popsicle stick
• Raro
• Baking soda
• Paper or plate

Instructions:

1. Wash your hands thoroughly with water and soap.
2. Get all of your equipment required.
3. Put the paper/plate on your table. 
4. Get a pile of all of the three powders. 
5. Using your popsicle start mixing some of each powder together. 
6. Taste the sherbet.
7. If there is too much Baking soda, add more Citric Acid.
8. If there is too much Citric Acid, add more Baking soda.
9. To improve the flavor, add more Raro.

Results:

 

 

                                                 My sherbet tasted very sour and bitter. 

Discussion:

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

• When an acid is mixed with a carbon carbonate they react to from carbon dioxide gas, water and salt the bubbles on your tongue are carbon dioxide and the reaction is sped up because the mixture dissolves the saliva. The breakdown of citric acid into carbon dioxide is a very important process inside your body and it's called carboxylic. 
  
  

What was the chemical reaction in the sherbet?

• The chemical reaction is made from citric acid and sodium bicarbonate. A reaction is caused by bubbles of carbon dioxide when dry ingredients get wet from saliva. 

What type of chemical is it?

• Neutralisation
