Science - Climate Change and the Future

Aim; To look at the different ways we can prevent climate change in the future.

How is sea level rise going to effect us in NZ

What places will be effected?

Pacific Island, New Zealand (Different places near the sea)

What else do we need to think about?

Where you live, Where to build houses,

What other places around NZ will be affected?

Auckland - Har bour, Lion rock, Nelson, Bay of islands and more

What does this do to our drinking water?

Salt water, Sea level rise

What are the main concerns?

1.  One of the main concerns are where to build your houses as the sea level rise can floud those houses  
2.  The second one is that we will stat to get salt water into our drinking system.

What can we do to prevent climate change?

What can we do?

1.  Build our houses away from the sea
2.    STOP plastic

Curbing climate change

What is the one, silver bullet solution?

There is no silver bullet 

What is the mix of things we need to start doing?

1.   Renewable 
2.   Solar heating
3.  Transport

What are 3 others you can think of?

1.  Walk
2.   Cycle
3. recycling

Activities:

Carbon Footprint: 

Carbon Footprint explained

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

Ecological Handprint The Ecological handprint builds on the concepts from the Carbon Footprint. We will look at the positive actions of:

1. Transportation
2. Community
3. Consumption
4. Water
5. Food
6. Home
7. Waste

1 Colour: For each action you are already doing 

2 Colour: For each action you would like to do in the future

Science - Reflection

AIM: TO LEARN ABOUT WATER ON EARTH.

Definition:

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.

THE WATER CYCLE SONG

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.  Vivid
2.  2x Bags
3. 1/2 Water 
4.  1 tbsp of baking soda

Steps:

1.  Draw your water cycle
2.  Carefully add the water
3.  If your doing the acid one, add 1 tbsp of baking soda and litmus paper at the top
4.  Add some food colouring
5. Wait at least 2 - 3 wks

Two Images:

Findings:

	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desert Water Cycle Bag 3
Does it cycle?	2	3
Amount of Water	2	3
Acidity	1	3

Key: Water and acidity amount: 1 = none 

2 = small 

3 = large 

Conclusion:

The normal water cycle had less condensation than the other. The normal bag didn't have any Baking soda involved

The water cycle with the acid, had changed the colour of the litmus paper to red after it started out blue.

Science - Greenhouse afect

Aim: To look at climate change and the greenhouse affect

Aim: To see how hot it could get with a heat lamp

Materials

1. 1 plastic bottle
2. 1 Teaspoon Baking Soda and Citric Acid
3. 1 heat lamp
4. 1 Thermometer
5. 100 ml water
6. 1 rubber band

Procedure:

1. Come and collect all of the materials from Mr Palmer.
2. Setting up the lights, bottles, thermometers and bungs.
3. Mr Palmer adds the baking soda mix along with 100ml of water.
4.  Wait for 5 minutes and start recording the temperature.

Variables:

All water added to the bottles was from the classroom tap

Minutes	Bottle 1: Water	Bottle 2: CO2 Gas
0	18.c	18.c
5	25.c	18.c
10	26.c	25.c
15	No Recording.	No Recording.
20	No Recording.	No Recording.
25	No Recording.	No Recording.
30	No Recording.	No Recording.
35	No Recording.	No Recording.
40	28.c	38.c

Conclusion:

The normal bottle of water didn't get as hot as the CO2 water. This is just the same as climate change. I also found this experiment interesting.
