Our Immune System

Friday (26/06/2009)

a) Video Clip
· It is a challenging topic for the kids. Fortunately, I found some easy and interestimng video clips on the Discovery Channel. We watched together.
· The kids were surprised that a single bacteria cell could copied themselves into millions when it got into our body. Likewise, our white blood cell could duplicate themselves. The kids thought it was amazing how the white blood cells swallowed the pathogen or bacterias.
· They learnt new words such as antigens, antibody, vaccine and also saw B Cells and Killer T Cells. They saw how the Lymphatic Nodes produces more white blood cells to battle against the alienated pathogens…..wow!

b) Vaccine
· They heard the word vaccine and asked about it. In layman’s term; it is a medicine against the pathogens in our body. Vaccine would strengthen our immune system and fight them.
· Vaccines are actually good bacteria. These good bacteria are being bred in eggs and then after a while, being transferred as vaccine in small bottles.

c) The Legendary Michael Jackson
· Michael died of heart failure. The kids were anxious of his look and wondered why he turned from black to white. One of the kids said, her mother mentioned about skin cancer.
· We watched and sang a video clip by him, Heal The World. They loved it and we tried interpreting the important sentences.

d) Modifying The Hula Hoop Game
· We wanted to create more interesting games.
· Thus, this time; we used a small and a big hula hoop. The first person hold the big hoop would have to go through it and pass it to his or her friends. Whatsoever, they musn’t let go their hands. They really had to work as a team intelligently. Any violation of rule, they have to restart the game.
