 At week 7 we started a project for Business and enterprises.

wow





















We were planning to do afghans and banana milkshakes but it was a bad idea so we only did afghans.
He has called our company Cookie Town (specifically baked for you).

Things have gone well yesterday (Wednesday) We were the 1st to sell out. I bout a Afghan milkshake a fizzy drink cotton candy and Oobleck.

Market day is so cool, I get to buy some stuff I also have time to relax, have something to eat and so much more.

Market day, My favourite type of event.

can experiment

Aim. to see what happens when you put a heated can in cold water

Hypotheses. shod crush the can

the method. put some hot water into a sprite can and put it on an element and wait for it to steam a lot and then be careful not to burn yourself and then put it upside down and an ice cream container of cold water.

Result. the can contracted cause of a lack of pressure inside

why it happened.

What are we learning in chemicals

What are we learning in chemicals? 

Particle theory is the six rules of particles these are the six rules. these rule help determine how a substance will behave.  

- all matter is made up of particles 
- all particles in a pure substance are the same
- there is space between all particles
- particles are always moving 
- there are attractive forces between particles 
- temperature affects the speed at which particles move particles e.g fast-moving particles are hot and vice versa

Diffusion: Is the movement of particles from areas of high concentration to low concentration.
e.g perfume, or like if you add CO2 and O2 (in a matter of seconds).

Aim: To observe the effect of temperature on the speed of diffusion.
hypnosis: hot= fast cold=slow 
method: we added potassium permanganate to hot and cold water at the same time to see how fast the diffusion would happen. 

The explanation: the hot water moves the die much faster than the cold one it did this because the particles in the hot water were moving much faster because of particle theory rule number six and also because there more heat = energy.
