today we studied about earthworms. we first went for earthworm hunting. for this process we used water, salt water and soap water.we poured different types of water on different places (which had more earthworm granules present). so that the earthworms could come out of the soil. after collecting them we did a test, that in what kind of water do earthworms stay happy/ alive? for this experiment we needed three test tubes, three earthworms and the three different kinds of water (normal water , salt water, soap water). after doing this test I observed that the earthworms were in good condition in the normal water. but in the salt water one earthworm died. and in the salt water the condition was stable.
