What a fascinating Science lesson 4H had learning about how our Organs work together. They now know we have 78 organs in our body and have learnt about our nervous system - sending messages to the brain, circulatory system - platelets coming together, respiratory system - capturing the oxygen in the air, musculoskeletal system - bones are stronger than concrete, immune system - the more you laugh the more hormones are released and digestive system - a person produces 2 cans of saliva in a day. They had such fun acting them all out !
