To suggest rule for inheritance of earlobe type. Procedure /Method : rarr The lowest part of the ear pinna called the earlobe, is closely attached to the side of the head, i.e., attached or not, i.e., free. rarr Observe the earlobes of all the students in the class. Prepare a list of students. Enter the data about the earlobes whether they are free or attached. rarr Find out about the earlobes of the parents of each student in the class. rarr Correlate earlobe type of each student with that of their parents. rarr In the column write F for free earlobe and A for attached earlobe. Answer the following questions on the basis of the collected data: Which expression of earlobe is observed more in number in your class?

Suppose you accidentally find an old preserved permanent slide without a label. In your effort to identify it, you place the slide under microscope and observe the following features : (a) Unicellular (b) Well defined nucleus (c) Biflagellate - one flagellum lying longitudinally and the other transversely. What would you identify it as ? Can you name the kingdom it belongs to ?

To observe the response of plant parts to light OR To study phototropism in plants. Materials : Conical flask, wire mesh, cardboard box open from one side, water, two- three freshly germinated bean seeds. Procedure : rarr Fill a conical flask with water. rarr Cover the neck of the flask with a wire mesh. rarr Keep two-three freshly germinated bean seeds on the wire mesh. rarr Take a cardboard box which is open from one side. rarr Keep the flask in the box in such a manner that the open side of the box faces light coming from a window. rarr Observe after two or three days and note down your observation. rarr Now turn the flask and leave it undisturbed in this condition for a few days and then observe. Observation : In the initial position of flask, the shoot bends towards light and roots turn away from light. rarr After turning the flask, position of shoot and roots change, i.e., shoot goes away from light and roots turn towards light but after a few days shoot again shows bending towards light and roots move away from light. Are there differences in the direction of the new growth ?
