Science Wind power

Science (Wind Power)

Extreme weather

Measuring weather.

Definitions:

1. Anemometer:
2. Beaufort wind scale:

MATERIALS 

1. PLASTIC LID X4
2. TAPE
3. PENCIL
4. PIN
5. SKEWERS X2 

STEPS

1. Get all the materials you need.
2. Tape plastic lids to the skewers. (two on each skewer.)  
3.   Tape the two skewers together.
4.   Pin the skewers to the pencil.
5.   Test to make sure it spins.
6.  Go to winding spaces to see the wind speed.

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	0.5
2.	Old J Block site	1
3.	Grass hill in the quad	1
4.	Tennis Court gate	0

CONCLUSION:

There was much wind where we went today so the number of spins would be a low amount.

The places that had the most wind were the grass hill in the quad and the old J block site.

The field was the second most windest place in the school because it spun half the way around.

The Tennis Court was not windy at all and it spun 0 times.

2040 Documentary (science)

Documentary - 2040 by Damson Gameau

This afternoon for science we mixed with the other science group as the J block buildings are being shifted and no students were allowed to be in them, we got together to watch a documentary. This documentary was about Climate change, Damson wanted his daughters future to be better than it was today, so he travelled around the world to ask kids about what they would like to see in the future. 

What surprised me?

Something that surprised me was that cars were driving themselves, plus they were electric. How much this one person wants to change the world and how many people agree with him. Something else that surprised me was how much we could change having solar power, and that it can connect to your neighbours. 

What excited me? 

Something I found exciting was the amount of things that us people can change if we just make a little difference to this world. Like people have already started Bangladesh have started using solar power and making a huge difference to their homes. 

What worried me? 

Watching the documentary a lot of things worried me but when it came more into the documentary it kind made more scene. One thing I found very weird was people growing gardens on top of there buildings and houses. 

I think that if we start making a difference now we will have a much happier place!

Science - Decomposition

Decomposition

Aim: To learn about the rate that different materials decompose

Hypothesis: My hypothesis is that the banana is going to decompose the fastest. 

Materials: 

1. Bananas (piece)
2. White Styrofoam (piece)
3. Paper (piece)
4. Bread (piece)
5. x4 Test tubes
6. Test tube rack 

Steps: 

1. Firstly you need to have your experiment ingredients ready (Bananas into strips, white styrophone into strips, paper into strips and bread into strips.) 
2. Secondly grab your 4 test tubes and test tube rack, and put a piece of each thing into the 4 test tubes. 
3. Depending on how large the top of your test tubes are, will depend on if you need a bung or not.  

TODAY	Colour	Change	Observations
Banana	Yellow & brown	-	It was a multi colour between brown and yellow.
Paper	White	-	Ended up being cardboard, it was in small pieces.
Styrophone cup	White	-	The styrophone cup was white, it was also in small pieces.
Bread	Brown and white	-	The bread was normal, It was cut into a strip

Coming soon...

3 weeks	Colour	Change	Observations
Banana	Yellow/ Green/Brown /Black	The banana has gone from being a banana to a rotten piece of banana	- The banana isn't normal. - It's all mouldy.
Paper	Brown	-	- Hasn't changed since last time.
Styrophone cup	White	-	- Hasn't changed since last time.
Bread	Yellow/white/Brown /Black/orange	Has turned into a very disgusting thing to look at, smells really bad.	- Colour change - Smells

Coming soon

5 weeks	Colour	Change	Observations
Banana	Orange, Brown, White, green	It's started to become really disgusting, still smells gross, it's starting to loose it's water.	- Smells - Colour change
Paper	Brown	Nothing	- Normal - No smell - No colour change
Styrophone cup	White	Nothing	- Normal - No smell - No colour change
Bread	Pink, White, black,	Has no water left in the tube, It's started to go pink, has different colours.	- Smells - Colour change

  

Water Cycle Cheek (science)

Water Cycle Cheek

Today in science we are cheeking up on our water-cycle experiment: 

	The Water Cycle	Acid Water Cycle
Does it cycle?	1	1
Amount of Water	1	1
Acidity	0	2

0 - None / 1 - small / 2 - big 

Conclusion: The water cycle experiment is a very slow process. It takes a lot of patience to get everything right and see the changes in the bag. As you can see in the table above both water cycles have worked, bag one has no acid in it so it's a 0 (doesn't mean it didn't work). When you know that the experiment is working you will start to see some condensation in the bag, which means the experiment is working. 

Coal vs Solar (science)

Coal vs Solar 

Today is science we did a test on our own stats about Coal vs Solar. 

Factor	Solar	Coal
Livability	8.5	4
Sustainability	10	2
Accessibility	7	3
Cost	3	3
Your choice...	Y	N

6 Sentences: 

1. Solar Power can give us power from the sun. 
2. Wind, sun & water are new reusable sources. 
3. Solar power is better resource then coal. 
4. Solar energy is a renewable source. 
5. We can capture power by using batteries. 
6. Both coal and solar have a cost.
