Climate change

My Investigation on climate change

ACIDIFICATION

What is happening to the oceans?

It is absorbing the C20 which is carbon dioxide as a result its making more acid.

What does this do to shellfish?

They won't be able to grow so the fish won't be as big and they won't be as big for us to eat

HOW DOES CLIMATE CHANGE CONTRIBUTE TO THE ACIDIFICATION OF OUR OCEANS? 

Ocean acidification refers to decreasing levels of pH in the ocean, which makes the sea more acidic. It is the long-term change in seawater chemistry due to the absorption of carbon dioxide from the atmosphere. Roughly 30 percent of human-made CO2 is absorbed by the oceans.

DEFORESTATION

DEFINITION: Trees being cut down

What are trees used for?

To help us breath and provide oxygen and keeps the water cycle going and running smoothly.

HOW DOES DEFORESTATION AFFECT THE CLIMATE?

It stops the water cycle from happening which means that weird things happen like more floods and etc. It can stop oxygen from getting released from the trees because the trees will stop absorbing the carbon dioxide. Trees collect water when it rains and if people cut down the trees the trees can't collect the water and they can't create oxygen.

ICE CAP MELT

DEFINITION: When the water is melting

If all the ice melted what would happen?  If all the water in the antarctic and everywhere else our water levels will rise to 230ft tall and land area would shrink significantly. There is 13 million cubic meters. If all of it were to melt the entire the while earth would feel the impact. Central china would completely disappear beneath the ocean in total 1-2 billion people could die/ displaced because of this. 

HOW DOES ICE CAP MELT AFFECT CLIMATE CHANGE? Sea levels would rise and 1-2 billion people alongside central china could be displaced.

WATER VAPOR

DEFINITION: Water in its gaseous state, especially in the atmosphere and at a temperature below the boiling point. Water vapor in the atmosphere serves as the raw material for cloud and rain formation.

HOW DOES  WATER VAPOR AND EVAPORATION CONTRIBUTE TO CLIMATE CHANGE?

Class treaty

Aim: To learn about  the expected behavior in a science laboratory.

Our R9 Class Treaty

1.   Bags under our desks 
2.  No food or drink  
3.   No running
4.   Look don't touch experiments
5.  Report any breakages or spills
6. Don't eat ,drink or smell any chemicals 

Safety in a laboratory.

In your group, discuss how the following scenarios could be dangerous.

1. Not putting your bag under your desk.
2. Running around in the laboratory.
3. Not wearing shoes in a laboratory.
4. Shaking a test tube with your thumb over its mouth?

How do we work in this laboratory?

1. Beginning and End of class: Lining up, Entry, Seating, 
2. Equipment tray: equipment list and details.

• Test tube - This is used  for experiments using liquids.They have a bung that can be placed in the top. Test tubes sit in a test tube rack.

• Measuring Cylinder - This is used to measure liquids for experiments. The liquids will be poured into a beaker or test tube once measured out.

• Glass Stirring rod - This is a 20cm glass rod used to stir and mix any liquids together.

• Spatula - This is for holding very small amounts of chemical powders.

• Test tube tongs - These are used to hold a hot test tube after an experiment.

• Conical Flask - This is used for experiments with liquid up to 150 ml. The flask has a rubber bung for the top and the glass is heat proof.

• Funnel - used to channel liquids into a smaller container.
