Evaporation experiment

We have been learning about evaporation experiment evaporation is where a liquid turns into a gas.

Aim-To evaporate copper sulfate to separate the mixture

Hypothesis-I think the blue will evaporate and there will be liquid.

Equipment-Copper sulfate solution,250ml Beaker heat proof mat,evaporation basin element.

Method
1 Set up element
2 Add 100ml of hot water to the beaker on the element
3 Add copper sulfate to the evaporation basin until its quarter full
4 Carefully place the evaporation basin on the top of the beaker
5 Turn on the element to 2 to warm it up and keep going on different to heat up
6 Heat the solution until most of the solvent has been evaporated and crystals of solute are forming.
7 Turn off the element careful not to touch as will be hot for a long time.

Observations -what did you see I saw bubbles and stem coming out that means it's getting hot at level 8 bubbles are know boiling just like pasta its is know very hot there are blue crystals coming out and smoke coming out and powder starting to form.
Conclusion-No our colouicion wasn't correct were thought that the blue will evaporate and there will be liquid
Discussion-We saw bubbles on 2 means it is heating up later on the bubbles came but steam came out at heat temperature they were starting to boil just like pasta would smoke coming out means it is very hot
Evaluation-Yes were did it was cool experiment.

Dilution

This week we have been learning about dilution and concentrated.

biomass

What is biomass? Organic matter used as fuel especially in power station for the generation of electricity.     

What are the 5 types of biomass?

1.   Wood Agricultural /
2.  Solid waste /
3.  Landfill Gas /
4.  Bio Gas /
5.  Alcohol Fuel/

What are three benefits of biomass?

1.   Renewable /
2.    Biomass is always and widely available as a renewable source of energy.
3.    It is carbon neutral.

What are three disadvantages of biomass?

1.    Biomass energy is not as efficient as fossil fuels
2.   .    It is not entirely clean
3.    Can lead to deforestation.

WEll done Saia

Research the following types of Biomass.
You will need to:

Write a definition of the each fuel.

Answer each question

• How is it made?
• What is it used for? 
• Where is it made? 
• What is it made with? 
• What countries use it?   

Place 2 images of the fuel.
What are its uses in the future?

Wind

Beaufort Wind Scale

Beaufort Force	Wind Speed (KPH)	Spins	Indicators	Terms Used in NWS Forecasts
0	0-2	0	Calm; smoke rises vertically.	Calm
1	2-5	10	Shown by direction of wind smoke drift, but not by wind vanes.	Light
2	6-12	40	Wind felt on face, leaves rustle; ordinary vanes moved by wind.	Light
3	13-20	80	Leaves and small twigs in constant motion; wind extends light flag.	Gentle
4	21-29	130	Raises dust and loose paper; small branches are moved.	Moderate
5	30-39	190	Small trees in leaf begin to sway; crested wavelets form on inland waters.	Fresh
6	40-50	250	Large branches in motion; whistling heard in telephone wires; umbrellas used with difficulty.	Strong
7	51-61	320	Whole trees in motion; inconvenience felt walking against the wind.	Strong
8	62-74	390	Breaks twigs off trees; generally impedes progress.	Gale
9	75-87	470	Slight structural damage.	Gale
10	88-101	550	Seldom experienced inland; trees uprooted; considerable structural damage occurs.	Whole gale

Wind speed - Making an anemometer.

MATERIALS

5.   

STEPS

1.   
2.   
3.   
4.   
5.   
6. 
   

Once you have made an anemometer we are going to record the wind speed.

Group size: 5

You will need:

Anemometer (above) 

Roles:

• Timekeeper
• Counter
• Recorder
• Anemometer Manager
• Wind generator

1. Mount the anemometer in a place that has full access to the wind from all directions.
2. When the time keeper says "Go", the counter in each group will count how many times the marked cup passes them in one minute and write it down.
3. If possible, repeat the above step four (4) times and record the average number of spins on the chart.

FINDINGS

• Record how many times it spins using the table below.

You will need to create the wind yourself by blowing. Get 4 different wind speeds by blowing.

You will need to time them and count the number of spins.

	Time Interval	Number of Spins
1.
2.
3.
4.

• Can you make a statement connecting the number of spins of your anemometer and the speed of the wind?
