Research questions: 1. What would happen if the temperature on which the Venus flytrap is kept in during winter increases from 4-10 degrees Celsius to the summer temperatures 20-35 degrees Celsius? 2. What would happen if the compost of the Venus flytrap changed from peat to a peat-free compost? Would that affect the growth of the plant and the life span? 3. What would happen if the Venus flytrap were to be watered with salt water other than rain water? Hypothesis When peat-free compost is used the plant, Venus flytrap, will grow twice as less as with peat compost when observed over a period of six weeks. Aim To determine the growth and the life span difference between when using peat compost against using peat-free compost in a fixed temperate …show more content…
• One pot of perlite. • Two Venus flytrap plants. • One pot of organic compost. • 5litres of rain water. • Two trays to put the rain water in. • Ruler (to measure growth). • Two medium sized empty flower pots. Method • Measure 60% of peat moss using a digital scale, do the same with the perlite compost but only 40% of that. • Put the 60% of the peat moss and the 40% of the perlite compost into flower pot labelled A = (peat compost) then put 100% of the organic compost into flower pot labelled B = (peat-free compost). • Put each plant into each pot, then put 100ml of still standing rain water in each of the trays. • Make sure the trays are of the same size. • Put pot A and B in each of the trays. • Put the two trays in direct sunlight. (by the window) • Check and measure the plants once a week (on that specific day) with a long mm ruler. • While checking on the plants add 50ml of rain water in each tray, every second day. • When measuring the plants be sure to record it and be vigilant on any colour changes. Precautions • Avoid skin contact with the fresh plant which can cause irritation and allergic reactions. • Make sure the compost with the peat moss and perlite is thoroughly
