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

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
