Hello Aspirant ,

Since you have not mentioned any specific subject I am providing the details about class 12 Physics ,Chemistry and Biology practicals .

Under physics there will be having experiments based on (i) ray optics and (ii) current electricity.The main skill required in group (i) is to remove parallax between a needle and the real image of another needle. In group (ii), understanding circuit diagram and making connections strictly following the given diagram . Polarity of cells and meters, their range, zero error, least count, etc. should be taken care of.

These are the list of experiments to be completed :

1.To find focal length of a convex lens by using u-v method (no parallax method)

2.To find f of a convex lens by displacement method

3.Using a metre bridge, determine the resistance of about 100 cm of  wire. Measure its length and radius and hence, calculate the specific resistance of the material.

4.Verify Ohm’s law for the given unknown  resistance (a 60 cm constantan wire), plotting a graph of potential difference versus current. Also calculate the resistance per cm of the wire from the slope of the graph and the length of the wire.

When it comes to Chemistry you will have :

1.Titerations in which the molarity,concentration in grams L-1 / molecular mass and number of molecules of water of crystallisation/ percentage purity will be calculated

2.Study of the rate of reaction where you will find the relationship of rate with concentration,volume and time.

3.Identification of compounds and its  functional groups based on observations where you learn to differentiate on the basis of colours,solution,ring and precipitate.

4.Characteristic tests of carbohydrates and proteins

5.Qualitative analysis: identification of single salt containing one anion and one cation.

Under Biology:

1. Taxonomy: Study floral characteristics through dissection of flowers, drawing floral formula and diagrams of the given family

2.Simple biochemical and physiological experiments-To isolate DNA from available plant material.

3.Slide preparation( of any locally available flower, to show marginal / axile placentation.)

4. Spotting: (Identifying, drawing a labelled diagram and writing at least two

identifying characteristics of the sample).
