Aim: To collect the eggs of different oviparous animals. Procedure
- Collect the eggs of as many oviparous animals as possible (e.g. frog, lizard, butterfly, bird, etc).
- Make drawings of the eggs that you have collected.
Observation: We will observe that the eggs of different oviparous animals are of different colours and sizes.
Conclusion: From this activity, it is concluded that it is easy to collect the egg of oviparous animals because they lay them outside their bodies.

Aim: To study budding in Hydra with the help of permanent slides.
Materials Required: Permanent slide of Hydra, microscope. Procedure
- Get permanent slides of Hydra and observe them using a microscope.
- Look out carefully for any bulges from the parent body.
- Count the number of bulges that you see in different slides.
- Draw the diagram of Hydra as you see it
Observation: We will observe a small single outgrowth or protuberance on the parent body. This bud develops into a tiny individual, which, when fully mature, detaches from the parent body.
Conclusion: From this activity, we can conclude that Hydra reproduces through budding
