  • 4x Gummy Bears of the same colour 
  • 2x petri dishes 
  • Paper towel
  • Marker 
  • 3x solutions( water, sugar water and salt water)
  • Electronic balance 
  • Beaker
  • Measuring cylinder 
  • Safety Glasses  
instructions:
  1.  Gather you equipment 
  2. Put you safety glasses
  3. Using the marker pen write the name of the condition on the petri dish. ( DRY, WATER, SALTWATER AND SUGAR WATER. 
  4. Weight the Gummy Bear and write the weight on the petri dish.
  5. Measure the 40 mL of the solutions and pour into the petri dish.

Skittles Colour Experiment



Aim:

I want to find out what happen when I put Skittles into water. 

Method:

Equipment

  • Skittles 
  • Petri dish  
  • Warm water 
  • Beaker 
  • White background 
Instructions 
  1. Get equipment 
  2. Put 8 Skittles in the petri dish  
  3. Spread the Skittles evenly.
  4. Gently pour warm water into the middle of the petri dish but don't overfill the petri dish. 
  5. Observe and record what happens. 
Prediction 

I think I will is going look like a rainbow tunnel 

Result :













I saw a colourful tunnel in the petri dish 
It was infecting into centre when it stopped it was mixing to the colour.

Discussion :

The outer colour shell of the Skittles dissolve and the colour was expanding. 
Somehow the colour didn't mix.

What is Dissolving : My Guess 
Example like putting something but it doesn't melt. It's like making hot chocolate you put the coca it to hot water then it dissolved it didn't melt. 
If you melt chocolate it turned to chocolate syrup you can freeze. But you put it to water you can freeze it but it takes a long time.  

The colour concentrated and it defuse and they spreed out. Because it human nature they don't want to be crowded. 

The colour had different solubility. 

What did Lebron James did for people

 Hello everyone, and welcome back to my blog,


Today I will be showing what Lebron James does for people. I picked Lebron James because he did a lot good thing and he had deal a lot of bad things. He was resilience because he quit the cavs and join in Miami heat team. A lot of fans hate him now because they supported Lebron but he betrayed them. But he ignore the fans who trying to make him feel bad. He donated so much for community and made a public school called I promise. Because he build a school for people can't afford to go to school. Here is the  poster that I done

Earthquake Heroes ( 2011)

Hello readers and welcome back to my blog. 



Today we talking about the 2011 earthquake in Christchurch. It took 5 years to clean the mess up. There's still thousand of homes not rebuilt. Some people saves people but they didn't have an a bravery award. Like Sam Johnson him and his team really help to clean the mess. Plus there firefighters, St john workers and officer didn't get a award. It cost 15.billion dollars - 30 billion dollars to fix everything. Here's my awesome work.
