Digital tech light bar

Hello for the past two weeks at Digital tech we have been focusing on making some LED light bars we had to get one big piece of wood about five to six centre meters with a tiny blue marking on it we also had to get two small pieces of wood with red markings on it and also two little ones with blue markings on it we then had to paint some glue to -0




















.

Tane Mahuta

Today at Tane Mahuta we done the same thing as last week accept we planted different varieties of plants we planted water melon seeds,carrots,corn seeds and sun flower seeds we had to dig some trenches up to plant them, it sure did take a lot of muscles to do the job but we stuck in and got it done I did have fun but not as much fun as I had last week I'm looking forward to doing some more next week and I also can't wait to see the plants grow.

My hero

Richie Mo'unga is a half Tongan and Samoan rugby player born on 25 may 1994 he made his first debut on the 27 of February 2016 with the chiefs. I look up to Richie Mo'unga because he plays for the all blacks plus he is a good kicker he just sets a good example for people to keep chasing your dreams he is a loyal person because he doesn't just play for the money he plays for the jersey and he reps our little island. one day i hope i will make to the all blacks but i will keep trying again and again to do my best to be just like Richie Mo'unga and i will keep trying to follow my dream and to have a clear mindset.

Here is a photo of him kicking the ball.

Issues of climate change

Issues Of climate change

Aim: To learn about the different activities that contribute to climate 
change.
1. Industry - They make clothes, cars, electronics, and processing which creates a lot of pollution.
2.Transport - every time a car gets turned on then it create carbon dioxide that goes to the atmosphere.
3. Waste - When it breaks down in landfills greenhouse gas is made.
4. Cows - Cows create green gas every time they fart or burp that is 25 times stronger than carbon dioxide.
5. Food - When people transport food it causes a lot of pollution like with all the planes and stuff.
6. Electricity - this has a source called fossil fuels that sends stuff to the atmosphere.

Solar energy

Aim: To learn about how solar energy is used.

Hypothesis. I think that black will attract the most heat.

Materials:

1. 3 cups black, white and clear
2. Thermal.
3. Paper, Tinfoil, and black paper.

Steps:

1. Get the materials.
2. Put tinfoil around the clear cup.
3. Put the tinfoil cup on tinfoil.
4. Put black stuff around the black cup.
5. Put the black cup on black paper.
6. Put the white cup on white paper.
7. Put a light in front of all the cups.

Wind cage ecperiment

Wind

Extreme weather

Measuring weather.

Definitions:

1.  Anemometer:
2. Beaufort wind scale:

MATERIALS

1. Plastic lid x4.
2. Tape.
3. Scheuer.
4. Pencil.
5. Pin.

STEPS

1.  Tape to plastic lids onto a Scheuer.
2.   Do the same as number 1.
3.   Tape the Scheuer's together like a cross.
4.   Put a pin through the middle of the tape in the middle.
5.   Stick the pin through the pencil eraser.

Groups size: 5 
Roles:

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

1. Mount the anemometer in a place that has full access to the wind from all directions.
2. When the timekeeper 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. Repeat the above step four (4) times and record the number of spins on the chart.

FINDINGS

• Record how many times it spins and record it in the table below.

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

	Place name on school grounds	Number of Spins in 15 seconds
1.	Field	1
2.	Old J block site	0
3.	Grass hill quad	0
4.	Tennis Court gate	0

CONCLUSION:

The tennis court gate had 0 spins, the field had 1 spin and the old j block site and grass hill quad had 0 amounts of spins I don't  think any of these places were gonna get any spins apart from the field because it wasn't as windy and as wide as the field. When we got to those places we had to time 15 sec then once we get to 0sec we move on to the next location, we asked what other people got they said they got 0 spins for most of theirs so not everyone had the same amount of spins. 

CIP tane mahuta

Hello today in CIP Tane Mahuta we went to the back garden and dug up some holes to plant some patatoes and sunflower seeds I really enjoyed doing it and it does use up a lot of my energy i did get tired but I kept trying hard to carry on I'm glad I am a part of the CIP Tane Mahuta group because we plant vegetables and lots more things that go to good uses so I feel pretty good cos I can be like I'm proud of myself because I helped plant those plants ect ect.

Water cycle experiment

Today in science we were learning about the Water cycle and climate change.
Condensation,water vapour,transpiration,evaporation and precipitation these are all things that are included in the water cycle.  The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. ... The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.

Today in science we were learning about the water cycle and doing some experiments we had to talk about this topic because the water cycle is getting destroyed due to deforestation, deforestation is when people cut down trees for a specific reason and don't replant it this destroys the way the water cycle works  because when it rains the trees take in all the rain fall than the clouds evaporate it but when there are no trees to in take the water it just sits there which goes off as surface runoff so yeah that's how deforestation is affecting the water cycle. 

We had draw a diagram of the water cycle using a vivid n an A4  zip lock bag then we had to pour some water into the A4 zip lock bag then put two drips of blue food colouring and seal it tight and tape it against a window and leave it there and you will soon see the water in the bag evaporating.


Conclusion

A week later i took a look at the A4 Zip lock bag and i could see the water evaporating and i also learnt some new facts about the water cycle and i really enjoyed doing the experiment.



Here is some other work that we done about the water cycle. We were given 10 shapes that had words in it that are about the water cycle. We had to put them together but it had to connect with the one it's connected to are you will have to change it around. The 10 words on the shapes were Evaporation, Condensation, Transpiration, Water cycle, Water vapour, Precipitation, Acid rain, Carbon Dioxide, Climate change, and Hurricanes. We had to connect all those on a piece of yellow paper and when we were finished we had to write on the paper why they connect together. Here is a picture of the paper me and my group made

Emotions

Hello today in Hurumanu drama we were set on ask to watch a video on a slide shared with us we had to describe three different emotions we could see during the video. The video we had to watch was the classic comedy TV series Mr Bean.

So what expressions did he show ?

Three different expressions i noticed when i was watching the video is his face expressions on some parts of the video he would have a smile on his face or he would just look relaxed. He would put a look on his face like what where is it so he looked confused sometimes. What i noticed about his body language is he was really fidgety and silly he seemed to be moving around a lot during the video so he was pretty active. He didn't really use any gestures so i cant really talk about that. 

Here is the video we had to watch

Renewable energy

                   Define and provide a picture of each energy type.

1. Hydro Energy. Hydroelectric energy is energy derived from the movement of water. Water has mass. It falls and flows downward due to gravity. When it moves, it has kinetic energy which can be harnessed. Kinetic energy  is the of motion of energy

    2. Solar Energy. Energy derived from the sun's radiation. solar energy is used
          on  Earth in various ways. It is used as a passive source of energy, for                          example, in the form of sunlight that comes through a window and heats up a              room, or as an active source, as in the conversion of sunlight to electrical                    energy in solar cells.

    3. Wind Energy. Definition of wind energy. "The energy of wind converted                 into useful form (usually electric current) is called wind energy is                                   renewable energy source. Once used can be replaced. ... The rotational                         energy of the large wheel is also used in wind turbine which produced                           electrical energy.

     

      4.  Wave Energy wave energy (or wave power) is the transport and capture of               energy by ocean surface waves. The energy captured is then used for                           all different kinds of useful work, including electricity generation, water                         desalination, and pumping of water. 

1. Type: Hydro
2. Is it used in NZ? Yes
3. Other Countries that use it? Over more than 150 do.
   How is it used to 
   generate 
4. generate electricity? Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.

1. Type: Solar
2. Is it used in NZ? Yes
3. Other Countries that use it? Other Countries that use it?Germany, Spain, Italy, Japan, the United States, and Czechia. 
4. How is it used to generate electricity? Solar-powered photovoltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business.

1. Type: Wind
2. Is it used in NZ? Yes
3. Other Countries that use it?  France, Canada, United Kingdom, Spain, Germany, The United States, and China.
4. How is it used to generate electricity? Wind power converts the kinetic energy in wind to generate electricity or mechanical power. ... As the wind passes the turbines it moves the blades, which spins the shaft.

1. Type: Wave 
2. Is it used in NZ? Yes
3. Other Countries that use it? Western coast of Scotland, northern Canada, southern Africa, Australia, and the Northwest Coast of the United States.
4. How is it used to generate electricity? Wave power converts the periodic up-and-down movement of the oceans waves into electricity by placing equipment on the surface of the oceans that captures the energy produced by the wave movement and converts this mechanical energy into electrical power.
