Mars

Hello people and welcome back.
Today we have been putting facts on a google drawing and searching about Mars there are many fact there are 8 that stood out to me and my friend.

Persevering Food

Hello people and welcome back to my blog last week me and my friends have done a slide about preserving food so it last longer there are four way to do.

This week we have been drying out beef to make biltong.

Science - Decompistion

Aim: To learn about the rate that different materials decompose. 

Hypothesis: I think that......the breed and banana is going to rotten down the fastest

Materials:

1.   test tube rack
2.   4 test tubes 
3.   bread 
4.   banana 
5.   card bored  
6. Styrofoam  
7.   water

Steps:

1. Need a group 
2. Get test tube and test tube rack
3.  You need to get banana,bread,cardboard,Styrofoam.
4.   
5.   
6.  

Findings:

TODAY	Colour	Change	Observations
Banana	yellowy and little brown		slimy
Paper	brown		flat
Styrophone cup	white		normal
Bread	breed colour		bumpy

• 
  

5 weeks	Colour	Change	Observations
Banana	green	moldy	the mold look kind of fluffy
Paper	brown	nothing	the paper has started to change colour at the bottom
Styrophone cup	white	nothing	starting to change colour at the bottom
Bread	still breed colour	a bit molly	it is starting to bend

Science - wind power

1. Anemometer:
2. Beaufort wind scale:

MATERIALS

1.   Sellotape  
2. pencil
3. pin
4. 2x sticks
5.   x4 cups
6. sticky note   

STEPS

1.  Tape the cup on the stick 
2.   make a cross with it 
3.  pin throw the cross to the rubber in the pencil
4.  
5.   
6.   

Group Investigation.

Groups size: 5 
Roles:

• Timekeeper ( watch)

• Counter

• Recorder ( Chromebook or refill )

• Anemometer Manager ( Anemometer)

• Wind Manager

Instructions:

• Go to the measuring place and set up your wind gauge.
• Make sure everyone in your group is ready to start their roles.
• Record how many times it spins and record it in the table below.
• Count the number of spins in 15 seconds.
• Record it on your chart.

FINDINGS

	Place name on school grounds	Number of Spins in 15 seconds
1.	Field	20
2.	Old J Block site	15
3.	Grass hill in quad<	10
4.	Tennis Court gate	3

• USING A,4 PAPER DRAW YOUR RESULTS ON A GRAPH.
• TAKE A PICTURE OF THE GRAPH AND UPLOAD IT TO YOUR BLOG

1 WHICH IS THE WINDIEST AREA AND WHY?

2 WHICH IS THE CALMEST AREA AND WHY?

3 WHERE IS THE BEST PLACE ON LAND TO BUILD A WINDMILL?\

1. The field is the windiest as the cars come past and make a lot of wind plus its a big space.
2. The Tennis court is the calmest as its all fenced off and there would be very little wind.
3. The best place to build a windmill would have to be the old J block site because people won't be over there most of the time and it's also out of the way of the children

CONCLUSION:

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
11	102-116	640	Very rarely experienced inland; accompanied by widespread damage.	Whole gale
12	117 or more	730+	Very rarely experienced; accompanied by widespread damage.	Hurricane

Based on your findings what was the Wind Speed and the Beaufort Wind Force for each area.

	Spins per minute	Wind speed ( kph)	Beaufort Scale
Field	16	6-12	2
Old J Block site	10	2-5	1
Grass hill	5	2-5	0
Tennis Court Gate	3	2-5	0

Science - climate change

My Investigation on climate change

ACIDIFICATION

DEFINITION:

What is happening to the oceans?

they are rising.

What does this do to shellfish?

they are it able to form

HOW DOES CLIMATE CHANGE CONTRIBUTE TO THE ACIDIFICATION OF OUR OCEANS?

2 Images;

DEFORESTATION

DEFINITION:

What are trees used for?

fire wood/making things cooking things

HOW DOES DEFORESTATION AFFECT THE CLIMATE?

2 Images;

ICE CAP MELT

DEFINITION:

If all the ice melted what would happen?

the animals that live there will not have any land to stand on and then the killer wales will eat them and the there will be no more of that kind of animal

HOW DOES ICE CAP MELT AFFECT CLIMATE CHANGE?

2 Images;

WATER VAPOUR

DEFINITION:this if it is on the water in the ocen  then the fish and animals water will start to get hot  and then they will start to die off one by one

HOW DOES  WATER VAPOUR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE? 

science - Rules in a science lab

Aim: To learn about  the expected behaviour in a science laboratory.

Our R9 Class Treaty

1.  Bags under desk
2.  No food or drink   
3.   No running
4.   don"t touch experiment 
5.  report any breakages or spill's 
6.   do not taste  anything or anything 

Safety in a laboratory.

teacher   shoes   practical  teacher laboratory   ask  sniff teacher  breakages 

1.   Follow the instructions given to you by the teacher .
2.   You must not enter the laboratory without your teacher .
3.   Report all breakages  to your teacher.
4.   You must never eat or drink in a laboratory   .
5.  shoes must be worn at all times.
6.   If you spill something you should tell your teacher  immediately.
7.  You should wash your hands after every practical activity.
8. You should know what you are doing. If in doubt ask your teacher.
9. Never taste or sniff  chemicals.

In your group, discuss how the following scenarios could be dangerous.

1. Not putting your bag under your desk.
2. Running around in the laboratory.
3. Not wearing shoes in a laboratory.
4. Shaking a test tube with your thumb over its mouth?

How do we work in this laboratory?

1. Beginning and End of class: Lining up, Entry, Seating, 
2. Equipment tray: equipment list and details.

• Test tube - This is used  for experiments using liquids.They have a bung that can be placed in the top. Test tubes sit in a test tube rack.
• Conical Flask - This is used for experiments with liquid up to 150 ml. The flask has a rubber bung for the top and the glass is heat proof.
• Glass Stirring rod - This is a 20cm glass rod used to stir and mix any liquids together.
• Test tube tongs - These are used to hold a hot test tube after an experiment.
• Spatula - This is for holding very small amounts of chemical powders.
• Funnel - used to channel liquids into a smaller container.
• Measuring Cylinder - This is used to measure liquids for experiments. The liquids will be poured into a beaker or test tube once measured out.
