Experiment #1; Respiration & Photosynthesis
Objective; To show the plants remove the carbon dioxide from atmosphere through photosynthesis process.
Briefing on method.
Pour the bromothymol blue into the bottle.
Blow!! And watch the colour change. DON'T DRINK. Coz u r fasting!! And it's poisonous!!
CO2 (from air blow) + H2O (from BTB) --> H2CO2 (Carbonic acid)
Experiment #2; Seed anatomy
Objective: To learn about parts of seed.
With a forcep, gently peel off the skin of the seed.
Take a magnifying glass and identify embryo, cotyledon, seed coat and leaves.
Record the observation.
Experiment #3; Looking for stoma
Objective: To examine the stoma on the leaf sample.
Take a leaf. Paint the underside of the leaf surface with a thick patch of nail polish. Make sure it doesn't touch the vein.
Since it's fun playing with the nail polish, we do it again. And again :-)
If u can get a clean patch of nail poilsh, u will get something like this under the microscope. This is how the leaf's stoma looks like.
