change of plans

instead of using coffee, coke and vinegar, i'm simply using sugar dissolved in water, salt water and pure water; this way, i can make sure that it's the one factor affecting the growth, instead of other factors that i might not know that are contained in drinks such as coffee and coke. e.g. caffeine.

my experiment

>>>>>(Draft)
Aim: To investigate the effects of different liquids on the same plants over a period of time
Hypothesis: The plant watered with vinegar will die and the others will live.
Equipment:
  •  5 pot plants (same species and similar size)
  • A measuring jug
  • Water
  • Coke
  • Coffee
  • Vinegar
  • Honey water
Method:
1. Place all five pot plants in a sunny area
2. regularly water each pot plant with the same amount of the allocated liquid
3. record all observations over this period of time.

Risk assessment:
i can't think of anything... but this is a draft, rite?

MWAHAHAHA

narrowed my ideas 

d
o
w
n
to one idea....
I'm going to do my previously mentioned idea- feeding five different pot plants five different liquids and measuring the amount of growth of each plant; in terms of leaf colour and height. Im planning to do this:
Pot Plant (victim) 1: Coffee
victim 2: Coke
victim 3: vinegar
victim 4: water
victim 5: honey water
( I'm going to feed them 20 mL of the selected liquid a day. )
Independent variable: the liquids which i am feeding them.
Dependent variable: the growth rate (height and leaft colour)
hopefully, i won't epically fail cough, and 20mL is enough,,, im not sure about how much liquids plants need, i dont want to drown them or thirst them to death (?) does that make sense, iunno.
and i still can't believe that i have to repeat THIS EXPERIMENT.
sigh. i adore science.

how expensive can inanimate, green things be?

sorry, ranting today.

i checked the rpices of an avergae pot plant and now im really annoyed. seriously, you'd think that plants would be cheap, considering that they're inanimate, green things that dont do anything but live and grow. gahhh. i'll probably be forced to pay for them myslef -.- i slaved at work for pot plants.

oh, and yea,,, i have to do it multiple times.

JOY.

what a way to start march.

... with ms zhang telling me that i would have to repeat the experiment MULTIPLE TIMES. as in, more than once. GAHHHHH. i so totally love science.

anyways, i now have to repeat in,  minimum TWICE.

fml. epic fail. gahhh.
