The Effect of Aspirin Concentrated Water on the Growth of Plants

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.

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.
