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.

Mentos and Coke experiment!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 Aim: 

I want to find out what happens when you drop mentos into coke.

Research

https://www.youtube.com/watch?v=uBq3f5nRr5U 

https://www.youtube.com/watch?v=n4MLPkTrOq4

Method:

Equipment

Coke bottle (no sugar) (size optional)

Pack of mint mentos, optional size (The more size, the more craziness!)

Towel (paper or not is optional)

Detergent

You could either use coke no sugar or sprite.

Remember, if it's a big pack of mentos, it has to be a big bottle of coke.

Instructions

1. get your equipment

2. put on your safety glasses

3. pour some coke into test tube or cup

4. place a towel under the cup

5. place the mentos into the test tube or cup

6. observe

Results

In the coke bottle, the surface of the mentos is rough, and that allows the bonds between the carbon dioxide gases and the coke, to break easier, helping the creation of carbon dioxide bubbles as the surface of the lolly is dissipating into the coke while the coke is busy fizzing about. Because the mentos are rather dense and collect moisture, they sink through the coke while dissipating and becoming a part of the coke which triggers a large bubble build up.

This was also the last science period until term 4, I'll miss you mr stock

Milk Plastic

 Aim: I want to find out how to turn milk into plastic.

watch this and i'll give you cookies

Method:

Equipment

• Oven or stove
• Measuring cup
• tablespoon
• a cup of milk
• pot or microwaveable container
• white vinegar
• paper towels
• spoon mug
• optional - food colouring, glitter       
• teaspoon
• plate or petri dish
• plate

     instructions

pour a cup of milk from a measuring jug (if you were using a jug like THIS - 

you would want to pour about 600mLs) into a pot or microwaveable container. if you're using a beaker then you pour 200mLs.

then, you heat the milk in a microwave or on a stove until it is steaming. 

put it on a bench or something and add four teaspoons of vinegar to a mug.

add the hot milk to the mug with the vinegar

once the milk is added and the vinegar has taken its effects, stir the milk with a spoon

stack four layers of paper towels on a surface that is safe to get damp

scoop out the curds with a spoon and place them on the paper towels

fold the paper towels over the curds and pres down on them to absorb any excess liquid

knead all the curds together into a ball of dough

once you're done, mold and colour the dough as much as you like 

if you want to, add glitter

put the dough on a plate or Petri dish and let it settle overnight

and you've done it!

SKittle Colours

 Aim: 

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

Method:

Equipment

• 8x SKITTLES
• warm water
• beaker
• petri dish
• paper towel

Instructions

1. get your equipment
2. put the skittles into the Petri dish
3. spread them around the sides
4. clean the beaker and dry it
5. gently pour the water into the middle of the Petri dish
6. observe how the skittles react.
   
   
   

This was a very fun experiment all in all.

Results: the skittles leaked their colours into the middle of the petri dish as soon as the water was tipped into it, and the only colour left in them was at the top where they could not be submerged by the water. That's called diffusion. As a result, most of them appeared to take a crystallised form. But, the reason the colours didn't MIX while they were taking the travels to the middle of the dish is because of something called water stratification.   That is the reason. The reason that the bottom half of the skittles will appear crystallised is because of the skittle's coating (called Shellac) being ripped off the lolly by the water along with the colour. It will also feel bumpy as it takes on the form. (don't take that the wrong way please. if you do that's not my fault)

The water also tasted very sugary because of all the colour of the skittles going into the water, obviously, and the colours have sugar in them. That's my explanation.

Well, I don't know what else to say, apart from this MAY have been the most enjoyable experiment I've done yet. Maybe apart from the edible slime one, but as I'm writing this I don't know.

I hope you enjoyed reading this longer than average blog and I'll see y'all next week probably.

edible slime

 I want to find out how to make edible slime without getting poisoned. Here's a video I found on how to do it with certain recipes. https://www.youtube.com/watch?v=n2Zh0YCr81Y

Method:

Equipment

bowl

spoon

marshmallows

cornflower

Instructions

put around 15-40 marshmallows inside a bowl or paper cup and put them in the microwave for 30 seconds

get them out after 30 seconds and start stirring and mixing the marshmallows together until they're kind of like goo

add two tbsp of cornflour and mix it into the marshmallow-y goo

if you would like to change the colour of the slime, add a tsp of food colouring

start kneading the marshmallow goo

make it into a ball

make it into whatever shape you want and now you can eat it! :D

FINISHING RESULT: 

Gummy Bear Osmosis :)

Aim: 

I want to find out what happens when gummy bears are put in liquids.

Method:

Equipment:

Salt water aka Sodium Chloride (NA on the periodic table of elements) 

Normal water aka H2O 

Sugar water aka Sucrose aka Sugar Cane 

SOUR HARIBO GUMMY BEARS HAYEEEEEE (or any gummy bears)

Two Petri dishes      

Marken pen

Electronic Scales

Safety glasses

INSTRUCTIONS:

1. Get your equipment   
2. Wear safety glasses
3. Get your marker pen, and write your name and the conditions, AND the weight of gummy bears.
4. Do the experiment yeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Finishing results: 

Without Difference:

With Difference:

My sugar gummy gained the most weight out of the two. WHY? Because the gummy bear, before the sucrose was added into the Petri dish, had a low concentration of water to begin with. Then, when the sucrose was added, the small holes in the gummy did not allow large amounts of sugar molecules into the gummy bear, only a few could enter at a time, but the little water molecules could enter large amounts at a time, so over the night a lot of water molecules got in, and only a small amount of sugar molecules entered the gummy. It only really TASTED like sugar was in it because the colour of the gummy bear (red) had dissolved into the sucrose and the gummy was in the sucrose for the night. And the dry gummy only gained a little bit because of the dust that built up on the surface of it.
