Activity 7

Accuracy: To increase accuracy/ get the number closer to it's true value, increase it's decimal points
Reliability: To make an experiment more reliable, repeat the experiment several times to eliminate anomalies
Drawing graphs: (example)

 

Burning Sugarcane is not environmentally hazardous

when you burn sugarcane, it does not contribute to the greenhouse gases.the sugar cane is acting as a carbon sink since the farmer is not burning a long-term storage of carbon dioxide. It's also sustainable since the carbon is taken in next year when the crops are grown again

20.6 - The nutrient cycling and carbon cycle
For nutrient cycling :

Nutrient cycling is a concept that shows how nutrients are being used up and given out by organisms and their environment


It is essential for life, and must remain both balanced and stable.

Text book pg 187
For carbon cycle:
Carbon is part of the nutrient cycle. 


We drew a mind map which shows the carbon cycles 

We listed the natural.. 
sources 

• Animals
• Volcanic eruptions

sinks

• Fossil fuels
• Plants/trees
• Oceans (note that the ocean both absorb and release CO2)
• Atmosphere

stations

• Animals
• Marine Biota
• Plants/Ancient plants
• Fossil fuels
• Oceans
• Atmosphere
• Soil

We played that dice game with the beads to get a better sense of how the carbon cycle works

It is also found in the text book pg 188

Enviromental management

My name's Nirmala, and i'm in the Yr 10 environmental management class
I'm very interested in the environment, especially since people don't appreciate the environment that much, and they rather take it for granted. I want to learn how to stop things such as global warming or deforestation, and learn more about the delicate relationship between the animals and nature. 

I'm most interested in the biosphere, because i really like animals. I like learning about things such as their behavior, or adaption. I just find it nice to learn about different animals and how they function.
