Here is the video :

This video is from my best friend Venice. I did film a video of my own but the file was to big so I had to use Venice's. It's a time lapse so the video won't take to long to watch :)

Here is a photo of one of the hokey pokey blobs:

Discussion:

I noticed when I ate the hokey pokey it was chewy and very sweet. As I watched my class mates pour/scrap the hokey pokey onto the baking paper I felt satisfied. It felt very sticky and felt like sugar. My favourite part of this activity was eating the hokey pokey and mixing the mixture :) (Unfortunately we didn't use cookie cutters 😕 but that's ok).

Thank you for reading this blog post!!

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

Tasteless	Bland	I dont know
Chrunchy	Sweet	Apple
Crunchy	fruity	Pear
Tasteless	Sweet	Burger ring
Stale	Burger ring	Burger ring
Sweet, chewy	Sour	Sour coca cola bottle lolly

Discussion:

How do you taste food?

 

Food is tasted from the taste buds located on your tongue. There are many different types of taste buds and that is how you taste sour, sweet, bitter or salty. When you taste something sweet your taste buds send messages to your brain about what type of food is and what is tastes like. 

What are the different tastes?

There are four main different types of tastes they are : sour, salt, bitter and sweet. The three other tastes are umami which is savoury, astringent and pungent. 

Where are the different taste buds on your tongue?

In the front of your tongue is the sweet taste buds, salty and sour are on the sides of your tongue and bitter is in the back.

Does smell affect your taste?

Yes smell does affect the taste of food. Most of the time people judge food by the smell and that can affect the taste. As well as that about 80% of smell is what is responsible for what food tastes like. 

Eating Hot Chilli 🌶️🔥

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

 Research: 

Method:

Equipment:

• Coca-cola 
• Milk🥛
• Water
• Carolina Reaper/sauce 🌶️
• Popsicle stick
•  Plastic shot cups🥤
• Timer ⏲️

Instructions:

1. Get all of your equipment required.
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 is🔥.
6. Do experiment again but drink normal water after 2 mins.
7. Do the experiment again but drink coca-cola after 2 mins.
8. Drink milk and do the same experiment.

Results🔥:

                           The  first time I had chilli without anything  it was a rating of 10/10 it was really spicy.

 

                                          

The first time I had chilli with water it was a rating of 6.5/10 it was still a spicy.

The third time I had the chilli with coke  it was a rating of 3.5 it went away faster.

The fourth time I had the chilli with milk it was a rating of 2 I don't really like milk.

Discussion:

Why does chilli burn your mouth?

Chilli burns your mouth from capsaicin which is a which is a oil based molecule. The temperature is what triggers the heat in your mouth. Milk is what mostly helps the burn go away. Water  and soda doesn't really help you.

                                              Why did the milk reduce the burn?

 

Milk is known as a solution to help the burn from the chilli. Capsaicin is a burning fat, milk fat helps the burn desolve from the chilli. Milk contain a protein called caesin that helps break down the spice.

Bacteria around our School 🦠 🧫

Results:

I don't have my results because I couldn't do it. Because the jelly stuff on the agar plate melted.😤

So here is one of my friends results:

( Credits to Venice)

Bacteria colours:

White = E.coli (poo bacteria)

                        Yellow/gold = Streptococci (throat infection)

         Pink= Salmonella (food poisoning)

       Red= Meningitis (brain infection)

Orange= (worse version of yellow)

Fuzzy/furry=  Food fungus 

Smooth= bacteria

What is on the agar plate?

Venice's plate included fungus, e.coli, orange bacteria, streptococci. When I first looked at Venice's I noticed there was a lot of bacteria. The most disgusting part was the food fungus because it is fuzzy greenish blue bacteria.

Safety in the Lab

 Rules:

1. You must follow the instructions given by the teacher.
2. You must not enter the lab without supervision/permission .
3.  Report any breakages.
4. Shoes must be worn at all times.
5.  Do not eat or drink in the lab. 
6. If you spill something, tell the teacher then clean it up.
7. Wash your hands after doing experiments.
8. A heatproof mat should always be used when heating.
9. If in doubt, ask the teacher.
10. Never taste or smell chemicals. 

1. Liquids do not go into the bins, because they go in the sink and the liquid can leak onto the floor if in the bin.

2. Solids do not go down the sink because it can get stuck or block the sink, they go into the bin if not used.

3. Wear safety glasses when you do experiments, to protect your eyes and face because you can get seriously hurt if not weaning them. 

4. Put your chair under the desk, and stand at the bench when you do experiments, because you can hurt others or even your self. 

5. Bags do not go on the desks, because you can get your bag covered in chemicals or get it caught on fire.

6. Long hair should be tied back, because your hair can catch on fire and burned.

7. Do not smell the chemicals, because you can pass out/ faint on the table or floor.
