Laboratory Manual-Science - Class X, NCERT Publication.Assessment of Practical Skills in Science- Class X - CBSE Publication.Science-Text book for class X - NCERT Publication.Subject Enrichment (Practical Work) - 03 marks Internal Assessment – Term II (10 Marks each).Unit-II:(Chapter-8)Ĭlass X Science (086) Assessment Areas (Theory) 2021-22 Studying (a) binary fission in Amoeba, and (b) budding in yeast and Hydra with the help of prepared slides. Studying the dependence of potential difference (V) across a resistor on the current (I) passing through it and determining its resistance. Practical should be conducted alongside the concepts taught in theory classes.ġ. Big dams: advantages and limitations alternatives, if any. Examples of people’s participation for conservation of natural resources. Forest and wild life Coal and Petroleum conservation.
This portion of the Unit is not to be assessed in the year-end examination.Ĭhapter – 16 Management of natural resources: Conservation and judicious use of natural resources. This may be an assessment for Internal Assessment and credit may be given (Periodic assessment/Portfolio). They can be encouraged to prepare a brief write up on any one concept of this Unit in their Portfolio. Note: Learners are assigned to read the below listed part of Unit V. Biodegradable and non-biodegradable substances. Our environment: Eco-system, Environmental problems, Ozone depletion, waste production and their solutions. Induced potential difference, Induced current. Magnetic effects of current: Magnetic field, field lines, field due to a current carrying conductor, field due to current carrying coil or solenoid Force on current carrying conductor, Fleming’s Left Hand Rule, Electric Motor, Electromagnetic induction.

Series combination of resistors, parallel combination of resistors and its applications in daily life. Ohm’s law Resistance, Resistivity, Factors on which the resistance of a conductor depends.
Heredity: Heredity Mendel’s contribution- Laws for inheritance of traits: Sex determination: brief introduction Safe sex vs HIV/AIDS.Child bearing and women’s health. Reproduction: Reproduction in animals and plants (asexual and sexual) reproductive health-need and methods of family planning. Periodic classification of elements: Need for classification, early attempts at classification of elements (Dobereiner’s Triads, Newland’s Law of Octaves, Mendeleev’s Periodic Table), Modern periodic table, gradation in properties, valency, atomic number, metallic and non-metallic properties.
