Detection of Sugar in Urine :-
Glucose is a type of sugar that our body requires and uses for energy. Body converts the carbohydrates we eat into glucose. Having too much glucose in the body can be a sign of a health problem. Ordinarily, glucose (sugar) is absent in normal urine. But when the glucose level in blood exceeds the renal threshold of glucose (160 – 180 mg /dl), glucose starts to appear in urine.

This video explains how to detect the presence of sugar in the given sample of urine.

Rate of Transpiration :-
Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation. Leaf surfaces are dotted with pores called stomata, and in most plants they are more numerous on the undersides of the foliage. Transpiration occurs through the stomatal apertures, and can be thought of as a necessary "cost" associated with the opening of the stomata to allow the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants, changes osmotic pressure of cells, and enables mass flow of mineral nutrients and water from roots to shoots.

This video explains how to compare the rate of transpiration between the upper and lower surfaces of a leaf.
