EXPERIMENT 1
PROCEDURE : Which is better fertilizer (Sugarcane bagasse
fertilizer or market fertilizer ) ?HYPOTHESIS : It is hypothesized
that there is a direct relationship between type of fertilizer and
ph value of sugarcane bagasse.APPARATUS : Petri dish , dropper ,
test tubes , glass rod.MATERIAL : Sugarcane bagasse fertilizer ,
market fertilizer , distilled water , pH paper strip , pH colour
chart , litmus paper.VARIABLES : MANIPULATED VARIABLE : type of
fertilizers RESPONDING VARIABLES : ph value CONSTANT VARIABLE :
amount of distilled water
PROCEDURE :1. Take two strips pH paper.2. Take the test
solutions in separate test tubes. Dissolve the solid substance by
adding distilled water to it. Label the test tubes.3. Now, place a
drop of the test solution on one strip of the pH paper with the
help of a dropper. Use a fresh dropperfor each test solution.4.
Observe the colour produced and match it with the different colour
shades of the standard colour pH chart.5. Note down the colour of
thepHfrom the colour chartthat matches most closely with the colour
produced on the pH paper.6. Similarly, find the pH value of the
remaining samples by using a fresh strip of pH paper and a separate
glass rod or fine dropper for each one.

CONCLUSION : Sugarcane bagasse fertilizer is neutral medium
which is 7.
EXPERIMENT 2
PROCEDURE : How does the type of fertilizer affect the growth of
plants ?HYPOTHESIS : The hypothesis for this research project is
that type of fertilizer will cause a significant change in growth
of plants.APPARATUS : Soil , Water , bean plant , sugarcane bagasse
, market fertilizerMATERIALS : Blender , pots , gloves , trowel ,
light microscopeVARIABLE : Manipulated variable : type of
fertilizer Responding variable : growth of plants Constant variable
: amount of water and presence of sunlightPROCEDURE1. First, take a
fresh sugarcane bagasse.2. Then, dry the sugarcane bagasse under
presence of sunlight.3. After drying it , cut the sugarcane bagasse
into small pieces and then blend it until the sugarcane bagasse
become soft powder which can apply for plant as fertilizer.4. Next
, place potting soil in two small pots. Make sure that you have the
same amount of soil in each pot.5. Place three bean seeds into each
pot. Make sure that the soil in each pot is damp.6. Label the first
pot as A and second pot as B.7. Then , sugarcane bagasse fertilizer
is apply for pot A while market fertilizer apply for pot B.8.
Continue watering your plants as explained and once a week measure
the height of the plant. You may also want to count the number of
leaves as that is indicative of how well the plant is growing.
