The Revolting Review: 9Bu

L.O: Work together and perform in front of an audience

What Have I learnt? I learnt how to work together with other people to create and perform a musical

How does this work show my learning: It shows my learning by showing that I helped perform the musical

What did I find challenging? I found it challenging remembering the choreography and when to do it

What would I do differently if I did this again? I would give myself a more out there role

What did I enjoy? I enjoyed performing the musical because it was good to see all the hard work go to good use

What am I wondering? I am wondering what it would have been like if we did one of the other musicals instead

What was it like performing on the day? I was a little bit nervous but it was still really fun after 6 weeks of practice

The Behaviour of matter: Diffusion

Aim: To observe diffusion in a liquid.

Equipment: Beaker, water, a plastic straw, a crystal of potassium permanganate.

Method:

1. Half fill your Beaker with cold tap water.
2. Place the petri dish on your workbench and allow the water to become settled.
3. Using the plastic straw, put your finger over the straw and put in water. Remove finger and place a single crystal of potassium permanganate in the centre of the Beaker.
4. Observe for 5 minutes.
5. Repeat the experiment using hot water.

Discussion: In cold water, the crystal diffused in a rapid motion and went everywhere in the water.

In hot water, the crystal diffused mostly around the bottom of the beaker

Investigating State Changes

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

Equipment: A 250 mL, thermometer, Bunsen Burner, Heatproof mat, tripod and gauze mat, stopwatch, Retort stand and clamp, Ice Cubes

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

1: 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.
2: Set up the 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 use. 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 the data table below.
5: Light the bunsen burner and start timing with the 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 minutes.
