reflection 8 - Gavin

today we brought our filled survey forms to school for Yueh Hwa to check and see if they could be handed in. A couple of incomplete survey forms were rejected and I was told to ask someone else to do the survey. Yueh Hwa also wanted the names and occupations of the people who did the surveys so I had to bring back mine to wright down the names. Last week I was supposed to go to Yueh Hwa's house for the project on Monday but I did not go as i had CCA so I did not have much idea what to do for the surveys.

Malcolm Wu - Research on the Life Cycle of a Mosquitoe

IPW Research – Life Cycle of Mosquitoes

The mosquito goes through four separate and distinct stages of its life cycle and they are as follows: Egg, Larva, pupa, and adult. Each of these stages can be easily recognized by their special appearance. There are four common groups of mosquitoes living in the Bay Area. They are Aedes, Anopheles, Culex, and Culiseta. 

Egg : Eggs are laid one at a time and they float on the surface of the water. In the case of Culex and Culiseta species, the eggs are stuck together in rafts of a hundred or more eggs. Anopheles and Aedes species do not make egg rafts but lay their eggs separately. Culex, Culiseta, and Anopheles lay their eggs on water while Aedes lay their eggs on damp soil that will be flooded by water. Most eggs hatch into larvae within 48 hours. 

Larva : The larva (larvae - plural) live in the water and come to the surface to breathe. They shed their skin four times growing larger after each molting. Most larvae have siphon tubes for breathing and hang from the water surface. Anopheles larvae do not have a siphon and they lay parallel to the water surface. The larva feed on micro-organisms and organic matter in the water. On the fourth molt the larva changes into a pupa.

Pupa: The pupal stage is a resting, non-feeding stage. This is the time the mosquito turns into an adult. It takes about two days before the adult is fully developed. When development is complete, the pupal skin splits and the mosquito emerges as an adult.

Adult: The newly emerged adult rests on the surface of the water for a short time to allow itself to dry and all its parts to harden. Also, the wings have to spread out and dry properly before it can fly.

The egg, larvae and pupae stages depend on temperature and species characteristics as to how long it takes for development. For instance, Culex tarsalis might go through its life cycle in 14 days at 70 F and take only 10 days at 80 F. Also, some species have naturally adapted to go through their entire life cycle in as little as four days or as long as one month

Reflection 7 - Justin

This week we reviewed the survey questions. It turns out some question were not very good or could not carry out the right message. So Mr Seow recommended that we rephrase our questions. We also decided that we we should interview about 20 to 30 people. During the holidays we will try to get together and finish up our survey questions and start surveying people. Hope to complete the task by the end of the school holidays. Will be difficult due the team members individual activities...

This week we added on the number of people to be surveyed and edited the survey questions even more. We increased the number of people to be surveyed from 20 to 30. Our questions were also reviewed by our teacher and we were asked to go through them again and see if we could come u with better questions. The teacher also gave us some idea on how to present.

Grace Blog Reflection 7 - Lim Yueh Hwa

This week, we are supposed to come with our survey questions, show it to our teacher, formalize it (putting it into a table), conduct our survey by asking other people and going to various places to interview them and finally, after the blog, post our reflections about how we felt about the survey.  

Malcolm Wu Week 7

This week, we were suppose to make survey questions for our interview but we had already done it. It was just that our questions we made up are reasonable but we have to rephrase them as it didn't seem to be in proper english or wasn't written properly. Therefore we had to spend about half of the period asking someone that is good in english to help us think of ways to make our questions sound better so that the people that we are going to interview have a much better understanding of what we are trying to ask and hopefully can give us a much more fulfilling answer or one that we most probably want to hear. After that, we still have to post our survey questionnaires on our blog and once we have done that, we have to conduct our surveys and after which, we still have to write down our experience on surveying the people and describe how we felt and our reactions when interviewing them on our blog
