Activity 10.3: Let us design

1. Take some bean or gram seeds and allow them to germinate on a moist cloth or a moist tissue paper.
2. Let them germinate until each of them develop into a seedling having a small root and a small shoot.
3. Now, take three glass beakers or tumblers, and label them as A, B and C.
4. Take three glass plates and attach a thick blotting paper to one side of each plate using a thick soft cotton thread.
5. Fix one seedling on each plate using a thick soft cotton thread, as shown in Fig., ensuring that the plant is not damaged.
6. Now, place one glass plate upright with a seedling attached into each of the beaker A and beaker C, as shown in Fig.a and Fig.c.
7. In beaker B, arrange the plate such that the shoot of a seedling is directed downwards and the root is directed upwards, as shown in Fig.b.

1. Pour water into all the three beakers to ensure that the seedling in each beaker remains above the water level.
2. In each case, let the bottom of the blotting paper get completely wet by soaking in the water. In this way, the seedling will get the moisture from the wet blotting paper.
3. Place beaker A and beaker B in sunlight as shown in Fig.a and Fig.b.
4. Position beaker C as shown in Fig. 10.2c. Place a cardboard box in such a way that the seedling gets light from one direction only through a small circular hole.
