  1. The Effect of Aspirin Concentrated Water on the Growth of Plants Tim Ko

  2. Problem Statement • Will the presence of aspirin concentrated water in soil affect the growth of plants?

  3. Hypothesis • If an aspirin concentration of water is increased, then plants will grow at a slower rate.

  4. Background Information • What is Aspirin? • How to Find the Concentration of Aspirin • Best Environment • Tomato (Lycopersicon esculentum)

  5. Design Diagram Title: The Effect of Aspirin Concentrated Water on the Growth of Plants Hypothesis: If an aspirin concentration of water is increased, then plants will grow at a slower rate. IV : Aspirin Concentration of Water

  6. Design Diagram (cont.) • DV: Height of Plants (cm) • CONSTANTS: type of soil, amount of soil, type of pots, water (tap), amount of water, type of plant, same environment, planting procedure, depth of seed, same type of aspirin

  7. Materials • Miracle Grow Soil • Tomato Plant Seeds • Water • 40 100 mL pots • Cups • Aspirin • Ruler • Clock • Mortar • Pestle • Scale • Spoon • Graduated Cylinder (100 ML)

  8. Procedure • 1) Plant 40 pots of tomato plants. • 2) Label 10 of the pots ‘control’ and label 10 of the pots for each IV (5 g/L, 10 g/L, 15 g/L) • 3) For 10 of the pots, water daily with 20 mL of tap water (control). • 4) Dissolve aspirin (5 g, 10 g, 15 g) in 1 liter of water.

  9. Procedure (cont.) • 5) Water respectively with 20 mL of water. • 6) Observe and record the growth of the plants for 4 weeks. • 7) Record observations in a data table.

  17. Statistical Analysis(ANOVA) • Control : 7.4 + 12.9 + 10.1 + 10.2 + 8.4 + 8.5 + 8.3 + 8 + 7.6 + 8.3 = 89.7 / 10 = 9 • 5 g/L : 3.6 + 4.2 + 2.4 + 2.6 + 2.2 + 3.8 + 4.3 + 3.7 + 3.3 + 2.9 = 33 / 10 = 3.3 • 10 g/L : 2 + 2.6 + 1.5 + 0.4 + 1.6 + 1.8 + 0.8 + 2.1 + 0.9 + 0.2 = 14 / 10 = 1.4 • 15 g/L : 0 + 0 + 0 + 0 + 0 + 0 + 0.2 + 0 + 0 + 0.3 = .5 / 10 = .05

  18. Statistical Analysis (cont.) • 5 g/L : 3.6 + 4.2 + 2.4 + 2.6 + 2.2 + 3.8 + 4.3 + 3.7 + 3.3 + 2.9 = 33 / 10 = 3.3 • 10 g/L : 2 + 2.6 + 1.5 + 0.4 + 1.6 + 1.8 + 0.8 + 2.1 + 0.9 + 0.2 = 14 / 10 = 1.4 • 15 g/L : 0 + 0 + 0 + 0 + 0 + 0 + 0.2 + 0 + 0 + 0.3 = .5 / 10 = .05

  19. Statistical Analysis (cont.) • Total Sample Size = 40 • Avg of All plants = 3.428 cm • SSTR = 10(8.97 - 3.428)2 + 10(3.3 - 3.428)2 + 10(1.39 - 3.428)2 + 10(.05 - 3.428)2 = 462.94 • SSE = 9(1.665)2 + 9(.744)2 + 9(.785)2 + 9(.108)2 = 35.58 • SST = 462.94 + 35.58 = 498.52 • MSTR = 462.94/3 = 154.31 • MSE = 35.58/37 = .96 • F-value = 154.31/.96 = 160.74 • Critical Value = 2.79

  20. Conclusions • Results support hypothesis • Experiment shows significant results based on statistical analysis.

  21. Types of Errors • Initial Planting Procedure • Inconsistent Watering of Plants • Different Environments

  22. Improvements • Keep all constants as “constant” as possible • More trials • Longer Experiment Time • Precise measurements

  23. Extensions / Applications • Experiment with other common medicines. • Be aware of where I dispose of medicine. • Prevent others from making the same mistake.
