CBSE Book Class 10 Science Practicals List of Experiments

LIST OF EXPERIMENTS (Only for MCQ Paper)

1. To Prepare

  a) A true solution of common Salt and alum

  b) A suspension of soil, chalk powder and fine sand in water

  c) A colloidal of starch in water and egg albumin in water and distinguish between these on the basis of

i) Transparency

ii) Filtration criterion

iii) stability

2. To prepare

  a) a mixture

   b) a compound using iron filings and sulphur powder and distinguish between these on the basis of :

i) appearance i.e. homogeneity and heterogeneity

ii) behaviour towards a magnet

iii) behaviour towards carbon disulphide a solvant.

iv) effect of heat.

3. To study the extent of cooling caused by evaporation on the following liquids, usinga thermometer. Also to arrange these liquids in the increasing order of the extent ofcooling produced

  i) Water

  ii) Alcohol

  iii) Ether

4. To verify laws of reflection of sound.

5. To determine the density of solid (denser than water) by using a spring balance and a measuring cylinder.

6. To establish the relation between the loss in weight of a solid when fully immersedin

  i) tap water

  ii) strongly salty water, with the weight of water displaced by it by taking at least two different solids.

7. To measure the temperature of hot water as it cools and plot a temperature- time graph.

8. To determine the velocity of a pulse propagated through a stretched string/slinky.

9. To prepare stained temporary mounts of (a) onion peel and (b) human cheek cells and to record observations and draw their labeled diagrams.

10. To identify parenchyma and sclerenchyma tissues in plants, striped muscle fibers and nerve cells in animals, from prepared slides and to draw their labeled diagrams.

11. To separate the components of a mixture of sand, common salt and ammonium chloride (or camphor) by sublimation.

12. To determine the melting point of ice and the boiling point of water.

13. To observe the onion peel cells placed in hypertonic solution under the microscope and draw labelled diagram of the same.

14. To study the characteristic of spirogyra/Agaricus, Moss/Fern, Pinus (either with male of female cone) and an Angiospermic plant. Draw and give two identifying features of groups they belong to.

15. To observe and draw the given specimens - earthworm, cockroach, bony fish and bird. For each specimen, record

  (a) one specific feature of its phylum

  (b) one adaptive feature with reference to its habitat.

16. To find the pH of the following sample by using pH paper / universal indicator

  i) Dilute Hydrochloric acid

  ii) Dilute NaOH solution

  iii) Dilute Ehanoic acid solution

  iv) Lemon juice

  v) Water

 vi) Dilute sodium Bicarbonate Solution
