Wind speed - Making an anemometer.

MATERIALS 

1. PENCIL.
2. TAPE.
3. PIN.
4. 4 STRAWS (2 CARDBOARD AND 2 PLASTIC)
5. 4 WHITE CUPS. 

STEPS

1.   Get 4 white cups.
2. Put 2 holes in each cup.
3.  Put the straw that you made in the holes that are in the cup.
4.   Put a cardboard straw and a plastic straw together (by putting the cardboard straw in a side of a plastic straw)

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 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. 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

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

CONCLUSION:

Hurumanu - Science - Recycling

Aim: To learn practical ways of recycling so that we can make our world a better place.

The Zero Waste Climate Solution movie

How can we prevent climate change by recycling these products?

Plastics:
Cycling or walking: You won't have to use your car and buy fuel for your car.
Paper: You don't have to cut more and more trees down.
Steel: You will be going to need to use coal if we burn all of the steel we have at the moment.

Video questions:

What is Zero Waste?
One of the quickest and the cheapest ways a community can immediately reduce climate impact. What can we do on the planet?

1.   Recycle.
2.  Reuse.
3.  Reduce.
4. Redesign.

What do we need to recycle?

1. Plastic - Bottle's, Straw's 
2. Paper.
3. Cardboard - Box's

What does recycling do?

cuts down more plastic that is on the land. and if we don't recycle things it kills our animals in the sea.

How much of our rubbish is food scraps?

What does soil due to carbon dioxide in the atmosphere?

What do we need to do?

1. Make People stop littering in the cities. 
2. Have Zero tolerance for littering.

What is a carbon footprint?

How can you make your Carbon Footprint smaller?

ENERGY SAVING TIPS FILM

Name 4 of the tips.

1.   Turn off the lights in a room if there isn't anyone in there.

I have three goals to try and achieve.

1. 
   

Science

Solo taxonomy.

1. Prestructural.
-no organisation.
-unconnected ideas.

2. Unistructural.
-one idea.
-shows how connected thoughts.

3. Multi Structural.
-2 or 3 ideas.
-slightly connectedness.


4. Relational.
-make links to other concepts.

5. Abstract.
-Bringing your ideas into other concepts.

Science - Week 3

AIM: TO LOOK AT THE WATER CYCLE AND how cLIMATE CHANGE IS AFFECTING IT.

Definition:

Water cycle

1. The cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

Scientific words:

• Evaporation. When water is heated by radiant energy it turns into water vapor.
• Transpiration. Evaporation from plants.
• Condensation. When water vapor cools, molecules join together and form clouds.
• Precipitation. When clouds get heavy the waters falls as rain, sleet, hail, or snow.
• Acidification: the action or process of making or becoming acidic.

We will be conducting an experiment that looks at the different ways that climate change is affecting the water cycle.

THE WATER CYCLE EXPERIMENT

Bag 1: Normal Water cycle

Bag 2: Water cycle with CO2 added: like Oceans in climate change

Bag 3: Water cycle with ice added: like Antarctica in climate change

Material:

1.  Plastic zip lock bag.
2.  Vivid marker.
3.  One cup of water.
4.   2 drops of food colouring.

Steps:

1.  One person needs to get the plastic zip lock bag and a vivid marker.
2.  Draw a water cycle on the bag.
3. Get a cup of water.
4.  Get a teacher to put two drops of blue food colouring in.
5. Hang the bag up on a wall and wait.

Two Images:

This is my groups first normal experiment.

My Groups soda water experiment.

Findings:

Conclusion:

Material:

1. Plastic zip lock bag.
2. Vivid marker.
3. One cup of soda water.
4. 2 drops of food colouring.
5. Litmus paper.

Steps:

1. Get a plastic zip lock bag.
2. Draw on the plastic zip lock bag.
3. Put one cup of soda water in the plastic zip lock bag.
4. Get the teacher to put in two drops of blue food colouring.
5. Hang the bag up on a wall and wait.

Charlesworth reserve

The classes who are going to Charlesworth reserve are AL WH and TS are going to Charlesworth reserve to plant native trees for native animals to live on/in here are some images of the place:

And more.

The government wants us to plant 1 Billion trees there for more native animals to come along to Charlesworth reserve and have a good life. What we will be planting Native plants for native animals to have a wonderful life in the freedom that they have. People might wonder who charlesworth is named after well i can answer that the reserve is named after Ceafl. And it is also a walk to go do so if you haven't gone to the walk you should try it then. If you are wondering who is the captain of Charlesworth reserve it is Christchurch City Council.

Science

Aim: To look at the causes of climate change and how to prevent it.

Climate Change video; The Facts video

As you watch the video answer these questions:

What is our greatest threat in thousands of years?

How do we see climate change affecting the globe?

1.   cars and truck ext. are bad because they make the air into pa-looted air that us humans breath in.
2.   Plants, if u give them too much water the will drown and die like humans basically but plants give us humans oxygen to breath in. 
3. our threat is that people wont remember this world and it will just be a giant ocean of water and there will be no one on earth living.
4.   without plants there wont be oxygen without oxygen there wont be people without people there wont be anything accept a planet of water. no land just water.

Write a reflection about what you have learnt about Climate Change and how it is going to affect 

Coal can affect us and our climate change by Coal causes global warming, which is linked with extreme weather and wildfires. Climate change is coal's most serious, long-term, global impact. Chemically, coal is mostly carbon, which, when burned, reacts with oxygen in the air to produce carbon dioxide, a heat-trapping gas.

Abby's Game

Hi I am Abby, in my group we have been looking at stopping littering

Aim/WALT:

1. We researched 3 kaitiaki they are:

Tangaroa - Oceans/Water

Tanemahuta - Land/People

Tawhirimatea - Air/Wind

I researched these to learn about them. 

2.We did coding on code.org or Code of hour. The aim of the games were to get a certain player safely to where the end is. There were different 

I made a game, this is the link to the game:

 https://gamefroot.com/game/abbys-game

In Reflection: I wish i could have more levels in my game next time and to have more time to finish it. From the start, i have now learnt how to make a game online and publish it.

If you have any questions then comment them bellow.
