Science T4 - Making Honeycombe

 Aim:

I want to find out how to make honeycombe.

Research:

ELMOOOOOO

How to make it

Method:

Equipment

• 5 tbsp or tsp of sugar
• 2 teaspoons of golden syrup
• half tsp of baking soda
• pot 
• Bunsen burner equipment (tripod, gauze mat and heat mat) or stove
• spatula
• baking paper

Instructions

1. Get your equipment.
2. Wash your hands.
3. Add your sugar and golden syrup to the pot.
4. Set up your Bunsen burner.
5. Use a blue flame.
6. Melt then boil the sugar for roughly two minutes.
7. Turn off the gas.
8. Add the baking soda and mix.
9. Tip out the honeycombe onto the baking paper and let it cool for approximately 5-10 minutes.
10. Clean up your equipment, and that is the final instruction for 2021.

Science T4 - Ginger Beer

 Aim:

I want to find out how to brew ginger beer.

Method:

Equipment

• ginger
• disposable cup
• water
• teaspoon and tablespoon
• lemon juice
• yeast
• sugar

Instructions

1. Get your equipment.
2. Put your name on a disposable cup, preferrably plastic.
3. Put half a teaspoon of ginger into the cup.
4. Add half a cup of water into the cup.
5. Add one tablespoon of sugar into the cup.
6. Mix with a spoon.
7. Add 5 drops of lemon juice to the cup.
8. Taste it and adjust the flavour to perfection.
9. Add 1/4 of a teaspoon of yeast.
10. Let it brew for a week.

Results:

When I added the ginger to the lemon juice, it sort of looked like diarrhoea. When you mix it, it does not lose its brownish color but most of the ginger dissipated. When you add the yeast, the yeast will not dissipate easily. 

TASTE TEST:

It was absolutely horrible and I have nothing more to say about it.

Discussion:

The yeast (micro organism), a living thing, is going to try to "eat" the sugar and when it does, it will release a gas called carbon dioxide (CO2), and effectively, it is going to excrete (poop) out some Alcohol. CO2 is the same thing humans breathe. This process is called Fermentation. This is the same thing that happens while making bread. When the yeast excretes, it will form bubbles on the bread from the CO2. This full process is called Respiration.

The best conditions for brewing ginger beer is in a warm place and let it sit for approximately a week. The optimal temperature for proper ginger beer brewing is 21-29 degrees celsius.

Science T4 - Blind Taste Testing

 Aim:

I want to find out if food tastes differently when you can't see or smell.

Research:

Method:

Equipment

Hands

Blindfold (OR SCARF)

mystery food

Instructions

1. Get your equipment

 2. Wash your hands.

3. Put on your blindfold.

4. Put your hand out for food

5. Pinch your nose with the other hand.

6. Eat the food and chew it.

7. Guess what the food is.

8. Release your nose and taste the food.

9. Where does the food react on your tongue?

Results: 

Food #1. I think it was sugar because it felt like there were a lot of small sugar pieces.

Food #2. It was 100% salt. There was no difference when my nose was pinched and unpinched.

Food #3. It felt and tasted like baking powder.

Food #4. It was definitely citric acid.

Food #5. It was a sour lolly. It felt very squishy, and I could slightly taste the citric acid in my mouth.

Food #6. It was half a burger ring. It was very crunchy and jagged.

Food #7.  Dry Marshmallow. It felt quite dry and hard. 

Food #8. 100% apple slice. 

Food #9. It was a gummy bear. 2nd favorite lolly! :D

Food #10. It was a pear. 

Food #11. IT'S DAIRY MILK CHOCOLATEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!

Food #12 (final food) EW ITS LEMON EW EW EW EWWWWWWWWWW (I spat it out into the trash)

Discussion 

Is there a difference between blocked and unblocked nose taste?

Yes, because when your nose is blocked it cuts off taste buds that are in your nasal cavities, and it also kills your sense of smell. You therefore cannot determine the food that easily.

Hot Chilli - Science T4

 Aim:

I want to find out the best way to cool down your tongue after eating hot chilli.

Method:

Equipment

• Hot Chilli Sauce
• Popsicle Stick
• Drinks - Soda, Water, Milk
• Timer

Instructions

1. Get your equipment ready.. obviously.

2. Get a drop of hot saucy on your Popsicle stick.

3. Lick the Hot Chilli sauce.

4. Optional - swirl the sauce around your mouth.

5. Start the timer.

6. After two minutes, drink your soda, milk or water.

7. After five minutes, how hot is your mouth?

8. Repeat the experiment but with a different drink.

Results:

The Carolina Reaper lives up to its name. 

After the first chug of water and the first dose of the death, I rated it a 10 for burning.

After the second time, I scored it a 10. 

After the third time, with coke, I scored it a 9.5.

After the fourth time, with milk, I scored it a 0.5.

Discussion

Why does chilli burn your mouth? 

The alkaline (oil based molecules) triggers the temp sensitive pain receptors in your mouth which then sends a message to your brain that is basically screaming "IT HURTS, IT HURTS!!".

Why did the milk reduce the burn?

Milk hosts a handy protein called casein, which helps dissipate the alkaline in the chilli, thus killing off the taste quickly.
