  1. Comparing Phosphorus Soil Levels Bessemer Park and Russell Square Is Chicago Sustainable? By Ruby D.

  2. Introduction! Phosphorus (P) is a key nutrient in plants development and is needed for photosynthesis. P is also needed to form all oils, sugars, and starches in plants( this is how we humans get our P- form plants) P is involved in blooming, root growth and helps plants handle stress. WHAT HAPPENS WHEN PLANTS DON'T GET ENOUGH PHOSPHORUS!: Plants that don't get enough P have thin-stems that are weak. Their growth is stunted or shortened, and their older leaves turn a dark bluish-green.

  3. How do plants get phosphorus? P is macronutrient that plants obtain from the soil Because it’s a macronutrient, plants need it in macro( very large) amounts.

  4. Our question! • My team wanted to know… • What is the difference in soil quality between our South Chicago community and other Chicago neighborhoods?!

  5. Our prediction and hypothesis! • My team predicted that. . . • The soil in Bessemer Park will have more phosphorus than South Chicago.

  6. Methods! • Procedures!: Testing the soil • Each group will recieve 2 Erlenmeyer flasks (125mL), each filled with 30mL of distilled water • Each Erlenmeyer flask has a rubber stopper and one pipette • Two people will recieve two ,Floc-ex, tablets and insert them into the flasks of water. Once the tablets have been inserted, the flask must be shaken until the pills are disolved • Once the solution is completely mixed and tablets dissolved, take three pinches of your soil and put into one of the flasks- then shake the soil/mixture vigiorously for one minute with the stopper on top.

  7. Methods • procedures: • Once the solution is completely mixed and tablets dissolved, take three pinches of your soil and put into one of the flasks- then shake the soil/mixture vigiorously for one minute with the stopper on top.

  8. Methods • Materials! : • Cups (four clear cups) • Tablets • Gloves (8) • Flower pots (4) • Ruler (cm) • Camera • Different soil (Houston, Russel square Park and Escanaba, Bessemer Park) • Seeds ( four seeds, or 2 Daisy seeds, and 2 Tulipes seeds) • Pipet (1) • Recording chart

  9. Methods! • Steps taken!! • Step One- different parks Russell Square and Bessemer park • Step Two-One cup of soil from each park (put on gloves). • Step three-label the flower pots (R) for Russell and (B) for Bessemer Park. • Step four- Plant one seed in each flower pot one daisy and one tulip seed for each park pot. • Step five- Put the flower pots in the window where they can get the same amount of sunlight. • Step Six- Water each pot until the soil is moist. • Step Seven- Record the days it started to sprout ( how long it took from day one?) • Step Eight- Also measure the different height of it every ten days. (With cm ruler)
