What is osmosis

Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes).

	Dry	Water	Salt water	Sugar water
Initial weight		5.51g	5.51g	5.51g
Final weight		4.28g	5.25g	6.40g
weight difference		gained 1.23	0.26g	1.2g
Initial volume		40mL	40mL	40mL
final volume		0mL	0mL	omL
volume difference		lost 40mL	lost 40mL	lost 40mL

Skittles Colour Experiment

 Aim:

I won't to find out what happens when I put Skittles in water.

Method:

Equipment 

• Skittles
• Petri dish
• Warm water
• beaker
• white background

Instruction

1. get equipment
2. put the 8 Skittles in the perti dish
3. Spread the Skittles around the petri dish evenly
4. gently pour the water into the middle of the perti dish
5. don't over fill the perti dish
6. observe and record what happens

Prediction:

I think I will see the skittles colour would head to the centre

Results:

I saw the colour of the Skittles moving into the centre slowly and if you shook it it turned brown.

Because all the colours of the Skittles mixed together.
