pH Colours

 Aim:

I want to find out what the colours of pH are.

Research:


Method:

Equipment
  • Acid - Hydrochloric Acid
  • Base - Sodium Hydroxide
  • Test Tube Rack with test tubes
  • Universal Indicator
Instruction
  1. Get your equipment
  2. Put 10 drops of Universal Indicator into the test tube.
  3. Add different amounts of acid and base into the test tube.
  4. Watch what happens to the colour.
Results:
Made a rainbow of all the pH colours in science! : r/oddlysatisfying
(This picture is not mine, because I didn't email the pictures I took to myself.)

Discussion:
What are the pH colours?
There are many different types of pH ranges, the colour red has the highest acid, and indigo and violet has the strongest alkali.

Making Sherbet

 Aim: 

I want to find out how to make a good sherbet

Research:

Method:

Equipment:

  • Citric Acid
  • Raro (Any flavour)
  • Baking Soda
  • A cup
  • A stick
  • A piece of paper

Instruction

  1. Get all of your equipment ready.
  2. Pour some of the dry ingredients on the paper, make sure it's all separated.
  3. Scoop a little bit of baking soda using your stick and put it in your cup.
  4. Scoop a little bit of Citric acid and add it to the cup.
  5. Scoop a little bit of Raro and add it to the cup, for some flavour. 
  6. Blend the dry ingredients on the cup.
  7. Wet your stick and dip it on the sherbet, if you feel like it doesn't have that much foam, add more baking soda, but if it doesn't have that much flavour, add raro. If its not sour enough, add more citric acid.

Results:

Honestly, it tasted good for me. It's because I like sour foods and I liked the sherbet I made. Once it touched my tongue, it started fizzing.

Discussion:

Why is Citric acid really sour?

Originally, Citric acid is made out of derived lemon juice, lemon juice is also sour. 

Why did it foam?

Once sherbet touches water, it starts foaming and fizzing. The reason why it foams is because, Citric acid is a sort of acid that is made out of lemon. Once you mix citric acid and baking soda and pour water on it, some atoms combine into carbon dioxide.

Skittles Colours

 みなさん、こんにちわ 
Minasan, kon'nichiwa (Hello everyone). 

Aim:

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

Method:

Equipment

  • 8x skittles
  • Warm water
  • Petri dish
  • Beaker
  • Paper towel

Instructions:

  1. Get your equipment.
  2. Put the skittles into the Petri dish.
  3. Spread them out around the sides.
  4. Clean the beaker.
  5. GENTLY pour the water in the middle of the petri dish so that it is half full.
  6. Observe what happens.

Results:




Describe what happened?
When I poured the water on the Petri dish, the colours of the skittles dissolved in the warm water. I ordered the skittles into the rainbow colours so that it looked good, the colours spread out in the middle of the warm water, and formed some sort of pie chart.

さようなら
Sayonara (Good-bye).

Edible Slime

Hello everyone, in Science we learned how to make edible slime.

Aim:

I want to find out how to make edible slime without getting poison.



Method:

Equipment:

  • 6/7 Marshmallow

  • 2 teaspoon of olive oil

  • 2 teaspoon sugar icing

  • 1 cup cornstarch

  • 1 bowl

  • 1 teaspoon / 1 Spoon

  • 1 Cup

Instruction:

  1. Get all of the equipment ready.

  2. Open the marshmallow packet.

  3. Put 6/7 of marshmallows inside the bowl 

  4. Put the bowl inside the microwave for 40 seconds.

  5. Add 2 teaspoons of olive oil inside the bowl to make the slime fluffy. (Makes the slime less sticky).

  6. Start mixing them with a spoon.

  7. Add a 1 cup of cornstarch.

  8. Start mixing them with a spoon.

  9. Add 2 teaspoons of sugar icing to make the marshmallow slime sweeter.

Result:

When we created the slime, the slime was very sticky. We tried to add more sugar icing so that it would be less sticky, but it didn't work. Here is a picture of the slime:


Thank you for reading this post, I hope you have learned something new. Bye!

Gummy Bear Osmosis

Hello everyone, in science, we are working on a gummy bear osmosis.

Aim:

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

Method:

Equipment

  • Sodium Chloride / Salt Water
  • Safety Glasses
  • Normal Water
  • Sucrose / Sugar Water
  • Gummy Bears
  • 2 Petri Dishes
  • Marker Pen
  • Electronic Scales
Instructions
  1. Get your equipment
  2. Wear safety glasses
  3. Using the market pen, write your name and the conditions (dry, water, saltwater, sugar water) and the weight of gummy bear
  4. Do the experiment.
Pictures:


Results:
Dry GummySugar GummyWater GummySalty Gummy
Initial Weight: (g)2.45g2.21g2.23g2.22g
Final Weight: (g)2.43g5.23g7.45g4.07g
Difference.2g -gain 3.02gain 5.22ggain 1.85g

The water gummy is the heaviest gummy, the reason why it became heavy its because the gummy absorbs the water. Gummy bears are dry when they are made, so when you put it to H2O, its most likely to loose it's colour and flavour.
The dry gummy didn't gain weight, but it lost weight because we let it out all night. So probably, it became cold.
The sugar gummy gained weight because gummy bears are created to be sweet, when a gummy bear and sucrose get mixed together.

Hands On Fire

Hello everyone, last week in science. We were working on how to set our hands in fire safely, but before we can set our hands in fire. We have to create a safety poster, I created a slideshow because it's allowed.  

Aim: I want to find out how to light my hands on fire safely.

Method:

Equipment

  • Lighter
  • Water
  • Gas
  • Tray
  • Hose
