What did I find challenging:I found doing the moves on time challenging.
What wound I do differently If i did this again: I wound have a lot more energy. 

science

Aim: To observe diffusion in a liquid
Equipment:
Petri dish or beaker
water
straw
a crystal of potassium permanganate

Method
1. half fill you Petri dish/beaker with cold tap water.
2. Place the Petri dish or beaker on your workbench and allow the water to become settled.
3. Using the tweezers, place a single crystal of potassium permanganate in the centre of the Petri dish/beaker.
4. Observe for 5 minutes.
5.repeat the experiment using hot water.








In cold water: The crystals stand together
In warm water: The crystals spread quicker then the cold water

Investigating State Changes

Aim: To observe water as it changes state from solid to liquid and then to gas

Equipment:
A Beaker
Thermometer
Busen burner
Heatproof mat
Tripod
Gauze mat
Stopwatch
Retort Stand
Clamp
Ice cubes

Method:
1. Collect enough ice so that you beaker is half full and place the thermometer into it while you set up the rest of the equipment

2. Set up you retort stand and clamp alongside the tripod and gauze mat

3. Place the beaker of ice on the gauze mat and gently clamp the thermometer so that it is held upright and the scale is easy to see.The bottom of your thermometer should be low enough to still be covered by water when the ice melts, but not touching the bottom of the beaker.

4.Record the initial temperature of the ice in a data table.

5. Light the bunsen burner and start timing with a stopwatch.

6.Measure and record the temperature every minute.

7.Continue measuring and recording the temperature until the water has been boiling for 2-3 min
