The Behaviour of Matter - Diffusion

Aim

To observe diffusion in a liquid.

Equipment

-250 ml Beaker

-Water Hot and Cold

-Tweezers

-A crystal of potassium permanganate

-Straw

Method

-Half fill your 250 ml beaker with cold water.

-Place the 250 ml beaker on your workbench and allow to become settled.

-Using the tweezers, place a single crystal of potassium permanganate in the bottom centre of the beaker using a straw.

-Observe for 5 minutes

-Repeat the experiment using hot water.

Results

 -Hot

-Cold

Discussion

-The particles in the hot water cause it to move more causing it to move apart eachother faster rather than the cold water.

Investigating State Changes (Matter)

Aim

To observe waster as it changes state from solid to liquid and then to a gas.

Equipment

-A 250 mL beaker.
-Thermometer.

-Bunsen burner.

-Heatproof mat.

-Tripod.

-Gauze mat.

-Stopwatch.

-Retort Stand.

-Clamp.

-Ice cube.

Method

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

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

-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.

-Record the initial temperature of the ice in the data table.

-Light the Bunsen burner and start timing with the stopwatch.

-Measure and record the temperature every minute.

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

Results

Time (min)	Temp (°C)
0	0°
1	6°
2	19°
3	29°

Discussion

Using the word particles and energy explain why the ice melts.

When the heat is added, the particles vibrate so much that they break away. When more of the heat is added the heat's energy it slowly melts the ice away.`

Reflective Post (Revolting Children)

Reflection:

We have finished our choreography for Revolting Children there is still some stuff that people can't follow, but all-in-all it all goods.

What have I learnt?

I have learnt the moves for the choreography and stuff about things in a Musical Theatre.

How does this work show my learning? 

By participating in a school performance I learn how to dance and sing also it lessen my shyness and will make me more outgoing.

What did you find challenging?

What I find challenging is performing the dance move at the right time and syncing with the people beside me because they are either too slow or too fast.

What would I do differently if I do this again?

Focus more and be more energetic.

What did I enjoy?

Nothing I'm not really a person who likes performing in a show.

What am I wondering?

If we would do better if we did something else.

What was it like performing on the day?

It was really scary especially when most of the people performing with you aren't there and you're just thinking the dance will just fail because the dance was missing some people.

 I was really proud of myself for going through it and finishing even though some people weren't there.
