Reflex Activity

Last week's task was to find a pair and together, test each other's reflexes with a ruler. The way that it was to be done was one person sits down and hangs one of their arms off a table, the other person would put the ruler over the top of their hand that was hanging off. After levelling it to the top of the hand the partner would drop the ruler, the amount of centimetres that were shown above the hand that grabbed the ruler before it fell were recorded. If you missed then it counted as a zero, the lowest (Best) you could get without failing was one and the highest (Worst) was thirty. We did three tests like that, one with our eyes open, the other with our eyes closed but listening for a signal to try and grab the ruler and the last with our eyes closed but were tapped on the shoulder. Before we'd started to test however, we were supposed to write a hypothesis, my one was that I'd do best on the listening- but I was wrong. I did the best on the looking tests, since I managed to get a one. After the tests were done, we then needed to get into a group of four with another pair. Marieta and I grouped up with Sky and Jericho. The test batch that we did the best on was the second test for hearing.

Body Systems

This week for inquiry the task was to first read about body systems and the skeletal system before playing a game, for the game you needed to place all of the bones of the skeleton in the right place. In the human body there are 11 systems, they are the circulatory, respiratory, digestive, excretory, nervous, endocrine, immune, integumentary, skeletal (which was what the game was about), muscle and reproductive system. There are also around 200-300 bones in your body, some fuse together when you go through puberty or just get older.
