light+colors

__ The Problem: __ How do plants respond to variation in light colour? __ Procedure: __ 1. measure equal amount of soil and put them in pots 2. put one seed in each pot (same kind of seed) 3. put each plant under a different colored light (of the same intensity  4.  Water each pot with the same amount of water every 2nd day.  5.  Observe the plants for 60 days. Record results. __ Hypothesis: I think blue will do the best because it has the widest spectrum.  __ __ Materials: four lamps of the color of blue, green, red, and normal, 4 pots, 4 seeds of the same type  __ __ Variables:  __ a.  Manipulated: type of lights  b.  Responding: __amount of growth (how many leaves) __  c.  Controlled: __ amount of water, number of seeds in each pot, amount of soil, what type of pot we use, amount of light   __ __ Observations/Logbook: __ __ Day 1: Date: ______________ __ No plants have grown  __ Day 3: Date: ______________ __ green light has grown 2 cm   the red light one has grown 0.5cm  the red light 2 has not germinated  the blue light has grown 3cm  the blue #2 light has grown 3cm neither of the regular lights have not grown at all __ Day 5: Date: ______________ __ Green light 2 has not germinated Green light has grown 14.5 cm  Blue light 16.5cm Blue light 2 21cm Red light 11cm Red light 2 14cm Regular light 12cm Regular light 2 12cm __ Day 7: Date: ______________ __ Green light: 16cm Green light 2: 0cm Red light: 16cm Red light 2: 17cm Blue light: 21cm Blue light 2: 23cm Regular light: 18cm Regular light 2:19cm __ Day 9: Date: ______________ __ __ Day 11: Date: ______________ __ __ Day 13: Date: ______________ __ __ Day 15: Date: ______________ __ __ data __ __ (add additional days as necessary) __ __ Conclusion: __
