Day 6: Biology Hands Activity

Day 6 : 29th april 2017 Report by Gaganashri.

     Today was an interesting and informative class. We all were eagerly waiting as we were informed by our teacher that today would be 'hands on activity' session.
   Before starting that session, Kamala mam gave us the glimpse of details regarding the field visits which will be held on the coming days. Although we were thrilled to know more, we moved on to welcome today's resource person Prof. Ramesh [HOD of Zoology] and Vishwanath [Vice principal of National College, Basavanagudi].
  We were soon divided into several groups and moved to Zoology lab. It was Prof.Ramesh 's lecture which allowed us to get into the world of 'BLOOD'. We learnt about the discovery of ABO blood. It is believed that ABO blood was discovered by Karl Landsteiner in 1901.

  We got to know many things. I have tried to summarise the lecture using the following sub heads:
• Discovery of blood
• Composition of blood
• Functions of blood which includes      Transportation, Protection, Regulation etc.
• Contents of blood
• Staining of blood cells i.e. Wright's stain
• Blood transfusion
• Cardiovascular system
• Lymphatic system
• Circulatory system
• Formed elements
• Erythrocytes, Leukocytes
• Blood group inheritance
• Functions of Lymphocytes
• Identification of blood group
• Rh grouping system
• Blood cell compatibility
   After covering all of the above topics, it was time to perform an activity which helped us to identify our blood group. Prof. Ramesh taught us to perform this activity. He also performed the same activity and identified the correct blood group of one of my friend. We all were actually surprised to know that our blood group could be identified in such a simple way.
  Then, we also got to know about some rear blood groups like Bombay blood, its disorders, OH blood group and we also got to know how the name Bombay blood was actually originated.
   After this, we were into 'Zoology museum'. We got a great opportunity to look into many specimens which included foetus, embryo, octopus, molluscs, different arthropods, amphibians and models of skeleton, human brain, sheep brain etc.
  We were soon shifted into Botany lab. This class was taken by Mr. Vishwanath. We were very happy to hear his lecture as he explained us in the most simple and detailed way. In his class we learnt about plant anatomy, monocot and dicot plant, xylem, phloem etc. We were even taught how to identify whether the given plant has monocot or dicot plant. He explained this with a very interesting and simple lab activity. According to that experiment, we should observe the temporary mount of a stem under microscope. If the vascular tissues are arranged radially, it indicates that the given stem is dicot stem. If the vascular tissues are scattered, it indicates that the stem belongs to monocot plant.
    This is just a small summary that i have tried to note it down. But, science is a very vast subject which includes observation, analysation, experimentation etc.
   However, it is rightly said by Oscar Wilde that "Success is a science; if you have the conditions, you get the result".
