SET UP ASSIGNMENT

Antifreeze Experiment and Climate Graph

Hey
My climate graph for some reason allowing it to be posted on this so I have sent it to Ms Zhang's email.

Equipment:

• 200 mL of water
• 5 Spray Bottles
• 5 10 x 14 x 5-cm. pans
• 5 of 250 mL Grass Seeds
• 2 100mL Antifreeze
• 1 100mL Recycled Antifreeze
• 5 4cm Pottting soils
• 5 0.25cm. Peat Moss
• 4 28cm of yearn
• 1 38 cm of yarn
• Ruler

Method:
Pans measuring 9.5x14x5cm should be filled with 4cm of soil. 250mm of grass seeds should be evenly sprinkled in the pan.  After a spray bottle has been filled with water, the spray bottle should be sprayed 40 times around the pan. The seeds must be  covered with 0.5cm of soil evenly. A light layer of peat moss should be over the soil and sprayed with water another 40 times. The four 29mm pieces of yarn should be used to wrap around the width of the pan 3cm apart. The one 38mm piece of yearn is wrapped around the length of the pan 3cm apart. The pan should be sprayed twice 40times evenly with water and these steps should be taken with three other pots. Two lamps with 60 watt bulbs should be placed above the pans (one on each side) and the growth should begin. This should continue for 18 days. After 18 days,  measure the height of the four intersections of the yarn. These measurements must be added up for each pan and the mean of grass height is calculated.  100mL of antifreeze should be mixed with 100mL of water to be sprayed over the first plant. This step should be taken with two other plants of two different antifreezes. The last pan will be the control pan and will have no antifreeze and instead be controlled with 200mL of water.  This will be continued for another 6 days. On day six, the height of the grass should be measured and recorded. The mean of the grasses should be recorded as well.
