Hokey Pokey

 ingredients

• 4 tbsp Sugar
• 2 tbsp Golden syryp
• 1 heaped tsp baking soda
• Pot
  
• Tablespoon and teaspoon
• Bunsen burner
• Paper cups

Method

1. put 4 tbsp of sugar and 2 tbsp of golden syrup  into a saucepan/pot and melt it.
2. bring to the boil and simmer gently for 5 minutes
3. add baking soda and stir vigrously
4. put the hokey pokey on a peice of baking paper to cool

Explination

Why do we stir it?

We stir it to stop the sugar from burning, the movement keeps all the sugar at the same temprature stopping it from burning.

explain why the hokey pokey rises and bubbles?

The hokey pokey rises and bubbles because of the gas the baking soda creates.

Neutralisation

Today in science class we tried to make the colours in the rainbow using a universal indicator, hydrocloric acid and sodium hydroxide. here is what happened

Matterials

• 2 pipetts
• Hydrocloric acid
• Sodium hydroxide
• Test tube rack
• Test tubes
• Neutraliser

Method

1. Take a test tube rack with 1 boiling tube at each end of the rack and 4 test tubes.
2. Quarter fill  the boiling tube at one end with Sodium hydroxide
3. Quarter fill  the boiling tube at one end with Hydrocloric acid
4. fill each test tube with 5 drops of univeral indicator 
5. using the pipettes slowly drop in different amounts of sodium hydroxide and hydrocloric acid into the indicator to make each colour
6. make sure you dont mix the pipettes

We managed to get every colour apart from yellow

The Mandela Effect

Recently I have been very intrested in the science of the 'Mandela Effect'. I decided I would listen to a podcast (Sci Guys episode 93 'Mandela Effect the science of false memories'). and I found it really interesting, so I decided to share what I learnt on my blog. Here is everything you need to know about the Mandela Effect.

The History of the Mandela Effect
The Mandela Effect is basically just a fancy way of saying false or fake memories. The Mandella Effect originated in late 1980s/early 1990s, It got its name when Fiona Broome explained in great detail how she remembered that former president of South Africa Nelson Mandela died in the 1980s while in prison ,even though he lived till 2013. 

She could describe the news coverage that happened because of his death and even a speech from his widow that never happened, and it wasn't that she was the only one who remembered that there were many people who thought they remembered the exact same thing.

What is the Mandela Effect?
Mandela effect actually is, many doctors think that the Mandela is a form of confabulation which is like a brainy way of "honest lying" which is like someone creates a false memory, but doesn't mean to lie to others.  They are just filling gaps in their own memories. Many examples of the Mandela effect are close and similar to the original memory.

 Researchers believe that people, even in large groups use confabulation to 'remember' what they feel is the most likely sequence of events. There are other aspects of memory that can lead to the Mandela effect, this includes something known as a false memory where you recall an event that isn't accurate. This is often a struggle for eyewitnesses to crimes or other things along those lines.

Some examples of the Mandela Effect
'I am your father' Vs 'Luke I am your father' there was never actually a 'Luke' in that sentence

'Kit-kat' Vs 'kitkat' KitKat had no dash

Is there black on the end of pikachus tail or not? Pikachu has no black on his tail












'Looney tunes' Vs 'looney toons' it is spelt 'Looney tunes'

Litmus Paper (science class)

 Materials:

1. Red litmus paper
2. Blue litmus paper
3. Sodium hydroxide
4. Hydrcloric acid
5. Pipette
6. 4 test tubes

Steps:

1. Rip the litmus paper in half and put it in each test tube
2. Add 3 drops of Hydrocloric acid to the blue litmus paper in test tube 1
3. Add 3 drops of Hydrocloric acid to the red litmus paper in test tube 2
4. Add 3 drops of Sodium Hydroxide to the blue litmus paper in test tube 3
5. Add 3 drops of Sodium Hydroxide to the red litmus paper in test tube 4

Findings

Blue litmus paper when added to hydrcloric acid turned red

Blue litmus paper when added to Sodium hydroxide stayed blue

Red litmus paper when added to Hydrcloric acid stayed red

Red litmus paper when added to sodium hydroxide went blue

Acid (Science class)

 What is an acid?

An acid is a liquid that has a PH(Power of hydrogen) level of between 1-7, it tastes sour and is used batteries and in our stomachs

What are 3 examples of acids?

Lemons- Citric acid

Vinegar-acetic acid

Batteries- sulphuric acid
