Work tasks.
1) Organize an initiative group to create a plan for greening the square. 2) Study the literature on greening design and based on what you have learned, develop your own plan for greening the square. 3) Create a list of necessary equipment, planting material etc. 4) Choose flowers for the square”s design. 5) Determine the agricultural techniques for growing the proposed plants, grow seedlings and plant them according to the plan for the flower garden in the machine operator”s square. 6) Make an economic calculation.
The flowers of our square. Our native land has very cold winter. The climate on Yakutia is sharply continental. So, our plants must be strong. We chose these flowers: Petunia, Marigolds, Viola, Phlox and sunflower.
Soil analysis. Plants grow in good soil, so we did a soil analysis.
Object: soil of Chymnai village.
Reagents: distilled water, 5% solution of potassium permanganate.
Equipment: magnifying glass, test tubes, flask, test tube stopper, filter paper, chemical beaker, pipette, glass plate, crucible tongs, alcohol burner, universal indicator paper.
Research methodology
Experiment 1. Mechanical analysis of soil.
Consider using a magnifying glass or a magnifying lens, the sample of soil given to you. Make a conclusion: is the soil an individual substance or a mixture of substances? If you decided that the soil is a mixture of substances, determine what type of mixtures the soil belongs to homogeneous or heterogeneous. Place in a test tube or flask 1-2 cm of soil, pour 4-5 ml of distilled water to it. Close the test tube with a cork and shake thoroughly for 1-2 minutes. Use a magnifying glass or a microscope to observe the sedimentation of soil particles and the structure of the sediment. Describe and explain your observations. Large grains of sand and clay particles will settle quickly, but the solution will remain cloudy due to the small soil particles suspended in it.
