Investigating The Ph of A Water Sample

It is important to monitor the chemical properties of the water we drink or use every day. The permissible pH of the water that is safe for our life and health is 6.5-8.5. If the pH is 3 to 5 it is too acidic for the survival of most organisms. Below the pH of 4.5, fishes die and only a small number of acid-tolerant insects survive. Likewise, a pH

to Study The Effect of Ph on Seed Germination

Aim: Seed germination is affected by the pH of the germinating medium. The amount and type of various minerals and quantity and quality of humus control the pH in soils. A specific level of pH is required for different seeds for maximum germination. The level of pH also affects the growth and development, reproduction and metabolism activities of t

Growing Yeast: Sugar Fermentation

Yeast is classified as a fungus and is made up of eukaryotic microbes, i.e, they have cells with nuclei. Fermentation is the process of breaking down a substance by bacteria, microorganisms or yeast. Yeast gets activated when mixed with sugar as it breaks down due to fermentation. Yeast alone or when mixed with water does not give any reaction. Mat

Effect of Sugar on Bean Plant Growth

Aim: To determine whether plants grew stronger and healthier with the addition of sugar while watering Abstract: Sugar is a source of energy. When sugar is added to water while watering plants, the plants should grow healthier and stronger as they get additional energy from the sugar. This could be observed by visual inspection and measurement of p

Effects of Diet on Blood Glucose

Aim: To investigate the relationship between blood glucose and diet in non-diabetic people. Abstract: a person’s blood glucose level rises after consumption of a high carbohydrate meal. Likewise, blood glucose would be low if a person consumes a low carbohydrate diet. Materials Required: Measuring the blood glucose level in 4 non-diabetic persons u

Factors Affecting Nodule Formation in Legumes

Aim: To determine which factors are important in the formation of nodules on legumes. Abstract: Rhizobium leguminosarum bacteria fix nitrogen for a legume plant and in return, the bacteria get shelter and nutrients in a nodule. Materials Required: 12 pots, 2 bags of vermiculite, a bag of potting soil, 36 snow pea seeds, Bacteria (Rhizobium legumino
