Making Ginger Beer


 Aim:

I want to find out how to brew ( make ) ginger beer.

Research: YouTube; 1. What is alcohol or how to brew alcohol? 2. How to brew Ginger Beer?

3. Science of Fermentation?


(Also just letting you guys know, YouTube is not letting me put the video in probably so I will have to put links instead. )                     


Research:

Link thing

 Ginger ( Quarantine Activity )

 Fermentation


Method:

Equipment:

  • Ginger ( source of sugar )
  • Warm water
  • Yeast
  • cup
  • spoon
Instructions:

  1. Wash your hands
  2. Get the equipment
  3. put one table spoon of ginger in the cup
  4. add one teaspoon of yeast
  5. Mix it all together
  6. leave it to ferment for one week
  7. after one week, taste it                                                                                                              

Results:

As you can see, I made it, we had to taste a little then put it on the window and then taste it after one week and taste it entirely, everyone said their ones tastes disgusting but I think mine tastes really good!



What is fermentation--->
Fermentation is a chemical change that happens in vegetable and animal substances. For thousands of years people have used fermentation to make bread, wine, beer, cheese, and other foods. The enzymes break down food into chemicals. When bakers add yeast to bread dough, the yeast breaks down the sugars in the dough. 
 ( OTHER WAY TO SAY IT: Fermentation is a process that involves the breakdown of carbs by bacteria and yeast. It results in a distinctive tart flavor and is used to make foods like yogurt, cheese, and sauerkraut.

REAL RESULTS AFTER A WEEK:


I didn't taste it because mine smelt so bad, like barf but way stronger, and had these white stuff inside, but from the smell I almost threw up, Mr tasted mine and he almost threw up. Plus it looked horrible. It was honestly disgusting.
 :( yuck...

Red cabbage undicator

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

Research: 1x YouTube video about Red Cabbage Indicators.

           


Method:

Equipment: 
  • Acid was hydrochloride Acid
  • Base was Sodium hydroxide 
  • Water
  • Cup/beaker
  • Test tube 
  • Dropper 
  • Red cabbage

Instructions: 
  1. Wash your hands
  2. Grab your equipment
  3. Put water into the beaker
  4. Cut the cabbage in little pieces and put it in the beaker with the water in it & mix the water with cabbage until its dark
  5. Grab the water colour of the cabbage beaker with the dropper and put some in each Test tube and you should count how many drops you put
  6. Get the Sodium Acid and Base acid 
  7. Put one of the acids or both in the test tubes and you should count how many drops you put in
  8. And make colours with the acids and cabbage water!
  9. Quest: Try to put more than 1 colour in a test tube without them mixing
  10. Now make your adventure of colours 😃

Results:     The colours went to dark to slowly light, the most surprising colour was yellow and when you could put another layer on a colour.           


Discussion:        Q1: What is an Acid and a Base-------------------

      HARDER EXPLANATION: An acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH. 

EASIER EXPLANATION: An acid is a substance that can donate a hydrogen ion (H+) to another substance. ... A strong acid will be able to let go of many or all of their hydrogen ions while a weak acid will hold onto some of their ions. Because acids donate hydrogen ions, all acids must have hydrogen in them.
  
                           Q2 :   What do chemical indicators do----------
 Chemical indicators are used to monitor whether the parameters to achieve sterilization have been met for a specific sterilization process.

                           Q3 : An ion is a special type of atom or molecule that has an electric charge. A hydrogen ion, then, is one that has a tiny electrical charge. Every substance in the universe is made up of hundreds and thousands of tiny atoms, molecules and ions. When a large number of those are hydrogen ions, the substance is acidic

Making Sherbet

 Aim:

I want to find out how to make sherbet.

Research: How to make sherbet video & The science behind sherbet:

                 

                                                     How to make Sherbet video---------------


The science behind sherbet-----------

Method:
Equipment
  • Popsicle stick
  • Citric Acid
  • Raro
  • Baking soda
  • Paper
Instructions
  1. Get your Equipment
  2. Wash your hands
  3. put the paper on your table
  4. get a pile of the three powders
  5. Using your Popsicle stick mix some of each powder
  6. Taste the sherbet
  7. if there is too much baking soda, add more citric acid
  8. if there is to much citric acid, add more baking soda
  9. to improve the flavour add more Raro
Results:

I wasn't here but my friends said that it tasted okay, she sent me a photo from the day though!  :) 😃


Discussion: 

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

What was the chemical reaction in the sherbet?
The fizzing sensation experienced when eating sherbet is a result of the chemical reaction between the citric acid and sodium bicarbonate. This reaction also produces small bubbles of carbon dioxide but only when the dry ingredients are wet by saliva in the mouth.

What type of chemical reaction is this?

                                                                   Discussion:
                                                       How do you taste food?:
 taste buds pick up clues about how a food tastes and sends messages about it to your brain along special wires called nerves. To taste something properly, you need to chew food into small pieces and to have a lot of drool, or saliva. This help the flavour molecules (also known as “tastants”) reach your taste buds.
                                                       What are different tastes?:
               Sweet, sour,fruity,slimy,Chewy,Biter,Salty,savoury,meaty,cool,hot,

                              Where are the different taste buds on your tounge?                         Each person has between 5,000 and 10,000 taste buds, most of which are located in papillae — the small rounded bumps on the upper surface of the tongue. Taste buds are also scattered across the roof of the mouth and the back of the throat.

Eating hot chilli 🌶

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

Research: Find a funny YouTube  of eating hot chilli. Find a video about science of chilli.

Funny hot chilli

Science hot chilli


Method

Equipment

  • Coca-cola
  • water
  • milk
  • timer
  • Popsicle stick.
  • Carolina Reaper.
  • Plastic shot cups.

Instructions

  1. Get your equipment.
  2. Scoop some chilli onto your stick.
  3. Start the timer and eat the chilli.
  4. Stop the timer after 4mins.
  5. Rate how hot your mouth is.
  6. Do experiment again but drink water after 2mins.
  7. Do the experiment again but drink coca-cola after 2mins.
  8. Drink milk🥛
Results 🥵 :

The first chill I did was without water and I am scoring it a 10 for burning.
*No video*

The second time, I had water and after 4mins I scored it a 6.5 for burning.

The third time, I had Coca-cola and I scored it a 9 for burning.

The fourth time, I had milk and I scored it a 2 almost a 1 for burning. ( hated milk ) :)


                                       Review:
     The coke for me made it worse and I feel like throwing up from that, all of them.

Discussion:
                                                  Why does chilli burn your mouth?:  

Capsaicin makes your mouth feel as if it is on fire because the capsaicin molecule happens to fit the receptors perfectly. When this happens, it triggers these receptors, which send a signal to your brain, fooling it into thinking that your mouth is literally burning.

                                                   Why did the milk reduce the burn?:
Milk is a solution when eating spicy foods. That's because milk helps your mouth handle capsaicin, an oily chemical compound in chilli peppers. ... Since capsaicin is fat-soluble, rinsing with milk fat helps ease the burn. Casein protein found in milk can also bind to the capsaicin and wash it away.

Casein is a slow-digesting dairy protein that people often take as a supplement. It releases amino acids slowly, so people often take it before bed to help with recovery and reduce muscle breakdown while they sleep. Several studies have shown it helps boost muscle growth, along with a ton of other benefits.
