There will be various places that will be affected.

What else do we need to think about?

Not to build places near the sea.

1.   Being able to use more renewable's.
2.   Using Solar heating.
3.  Start using public transport more often.

My Investigation

Where does our food come from?

• Choose your favourite food.

1. Upload a picture of it.
2. Draw a picture of it on A4.    

On your blog answer the following questions.

• Where does the food come from (e.g. is it from another province or country, was it purchased or made locally)? 

Pizza comes from Southern Italy. 

• How many kilometers away did the food travel to get to you?
  18.542km

• What are the main ingredients? 

Pizza dough

Pizza Sauce

Mozzarella cheese

 

• How is the food packaged? 

Pizza is packaged in a box when it is ready to go.

• What resources do you need to produce this food item (e.g. land, water, oil, food, etc.)? 

The resources needed to make pizza is natural resources. That may include Tomatoes, Onions, Mushrooms, Olives, Anchovies, Garlic, Peppers, Salt, Pepper, Oregano, Basil and Water.

• Would this item have been processed? 

Yes, this food has been processed. 

• Is there anything unique or significant about the food item (e.g. fair-trade, local)? 

Yes, its packaging. 

• What else do you notice about this food that affects its climate friendliness? 

When your finished eating a pizza your left with the pizza box and some people could not put it in the rubbish so it will create pollution.

• Do you think this food is climate friendly (Circle)?       YES   NO 

• Why?

Because Pizza is processed.

• If no, what would be a better alternative?  

To try process it less.

The water Cycle

AIM: TO LOOK AT THE WATER CYCLE AND HOW CLIMATE CHANGE IS AFFECTING IT.

Definition:

The Cycle processes by which water circulates between the Earths ocean's, atmosphere and land involving precipitation as it rains and snow. It will eventually evaporate then it will condense 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 vapour 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.  Marker
3.  1 cup of water
4.  2 drops of food colouring
5. litmus paper
6. soda water

Steps:

1.  Find your group of 3
2.  Get materials  
3.  Draw the water cycle on the bag
4.  Put 1 cup of water in the bag
5.  Put 2 drops of food colouring in the bag of water

Two Images:

 

Findings:

Conclusion: The water cycle is basically the earths cycle. Its goes round and round with Evaporation, Condensation, precipitation and transpiration. The water cycle is water from the sea because then it will evaporate and it will go into the clouds then it will come back when it rains. I will have more of an conclusion and findings when we next have science.

For the second bag we used soda water. We used soda water because it has carbon dioxide in it so it will create moisture in the bag. We put a piece of litmus paper in the bag so over a few days it will turn into a orange ish red colour. The litmus paper changes colour because of the carbon dioxide. It starts of yellow and it will change into red when the carbon dioxide comes out of the soda water and it will create moisture, then it will go into the litmus paper and turn it into red.
