Highlights – teaching body systems with Lego and diffusion with water and food coloring.
I started my first week off with a bang. As any new, keen student teacher would, I planned a number of activities and found there was not enough time for most of them. Many of them ended up rushed. Day one I took the students outside to talk about body systems. I had the students run around the track and then discussed what was happening in their body. I learned how long it can take a 13 year old to get around a track and so for the next class I simply had them run to the end of the school and back.
My next hands on science lab was to deal with the increasing complexity of how the human body is made. Cells come together to make tissues, tissues form organs and organs for organ systems. To demonstrate this, I had the students build with Lego. The class was split into 6 groups. Each group were given a specific structure to build. One group built the cab of a car transporter, another the back and trailer. Four groups each built a different car. We then came together and discussed how cells are like each Lego piece. Cells are small and specialized to fill a particular role and each Lego piece is as well. These smaller pieces come together to make a larger structure. We then compared how those structures fit together to make a larger organism by comparing the cab to the brain, the trailer to the skeletal and muscular system and then each car to a different internal system e.g. digestive system, respiratory system, etc.


In addition, this week I also taught a lesson on diffusion and osmosis. As this is such an important process in your body, I really wanted the students to understand it and how passive it is. It is amazing that we really so much on such a simply process for our very life. Each students observed how food coloring spreads out in a cup of water and then observed how a teabag works in order to observe osmosis. The students seemed to enjoy the opportunity to see what was happening and not just hear about what happens your body.
Over all it was a great first week.
