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.

Carbon footprint pledge

My Carbon Footprint

Carbon Footprint explained ( You tube)

Carbon Footprint handout

You will need:

1. 2 different colouring pencils
2. The Carbon Footprint Handout.

We will look at our Carbon Footprint under the following headings.

• Dwelling
• Water
• Recreation
• Heating and cooling
• Electricity
• Transportation
• Food
• Waste
• Air Travel
• Consumption

Colour 1: for actions they are already doing 

Colour 2: for actions that they pledge to undertake in the future

List 5 of the actions you pledge to undertake in the future.

1.  I will try to walk or bike everywhere.
2.  Try to never travel by plane.
3.  I'll try to compost and recycle.
4.  Try to eat only food i grow.
5.   Try to use efficient light bulbs and turn off everything when i get a chance.

Decomposition

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

Hypothesis: Bananas, white stylophone, paper, and bread. I think the bread will decompose the fastest.

Materials:

• Test tubes x 4

• Test tube holder.
• White stylophone.
• Paper.
• Bread.
• Bananas.
• Water.

Steps:

1. Set up a test tube holder.
2. Put 4 test tubes in the holder.
3. Put Bread in one tube.
4. Put paper in one tube.
5. Put white stylophone in one tube.
6. Put Bananas in one tube,

Findings:

3 weeks	Colour	Change	Observations
Banana	Yellow	Black/brown	Got fluffy on it. steam is brown. juice out. Stinks.
Paper	Brown	Brown	It looks exactly the same 3 weeks ago.
Stylophone cup	White	White	It looks exactly the same 3 weeks ago
Bread	White/Brown	Black/White	Changed form. black piece in it. A lot of water at the bottom.

Conclusion:

Science laboratory introduction

Our R9 Class Treaty

4. Not disrupting.   
5. Respecting equipment.  
6. Making good choices.
7. Put your hand up when you want to ask a question/ Don't call out.

Material:

• Test tube- They are used for most experiments to hold liquids. They have a bung that goes on top.
• Conical flask- used for experiments with liquids upto 150ml. The flask has a rubber bung for the top and the glass is heat proof.
• Glass stirring rod- 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- For holding very small amounts of chemical powders.
• Measuring Cylinder- this is used to measure liquids for an experiment. The liquids will be poured into a beaker or test tube once measured out.

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.
