Oral Task

Reflection On Weeks 1-5

During the past 5 weeks I have created 2 tasks on my topic about water filtration.
First I researched using the net and found an article that provided background information to help my understanding of the issues related to my topic.

With this information I created a summary on the topic and posted this on my blog page. This helped my understanding and provided me with more information to move to the next stage on Blooms.

During the "comprehension" stage I created my second task which was embed a visual snapshot to show the audience my understanding of the topic. We were asked to record our summaries as a video and embed the file into our blog page to demonstrate our oral language skills and ability to master intonation and expression. I found this difficult to do at first but Bibil was able to assist us and I was pleased with the final product.

Now i am preparing for the next stage of Blooms "Application" and I and deciding how I will design my next task that could include:  an interview, a simulation, a presentation using IT tools and illustration.

It's time for me now to plan my next task so please check my blog on Friday and post a comment.

Types of Filter

Filtering water
There are many ways to filter water to make it safer from germs . Some filters, like the ceramic filter below, require special equipment . Others need no special equipment and can easily filter small or large amounts of water before disinfecting .
Cloth filters
In Bangladesh and India, a filter made of finely woven cloth is used to remove cholera germs from drinking water . Because the cholera
germ often attaches to a tiny animal that lives in water, filtering out these animals also filters out most cholera germs . This method also filters out guinea worms . You can make a cloth filter out of handkerchiefs, linen, or other fabric such as the cloth used to make saris . Old cloth works better than new cloth because worn fibers make the spaces in the weave smaller and better for filtering .
1 . Let water settle in a container so that solids sink to the bottom .
2 . Fold the cloth 4 times and stretch or tie it over the mouth of another container or water jar .
3 . Pour water slowly from the first container through the cloth into the second container or jar .
Always use the same side of the cloth, or germs may get into the water . After using the cloth, wash it and leave it in the sun to dry . This kills any germs that may be left in the cloth . In the rainy season, disinfect the cloth with bleach . Be sure to clean the container you use to store the filtered water in, at least every 2 to 3 weeks .

Ceramic filters
A small water filter can be made from fired clay coated with colloidal silver (a substance that kills germs) . With basic training, any potter can easily make these filters .

Today (May 4th 2011) on period 2 which's personal project lesson, Ms Liz came to the class and explained me about Personal Project Written Information and she used some illustrations and examples. She gave us the outline if my personal project written information which helps me a lot. She advised me to do each paragraph every week. Below, are the outlines:

• What are you going to do with this in the future?

Each paragraph, the word is no more than 500. (limited)

Plan

In the last couple days, I'm done creating and designing my plan. The purpose of my plan is so that I can use my time much more wisely and effectively.

Materials

I've collected all the materials. It took me about 2 weeks to collect all the materials, cause I ordered activated carbon from my uncle. Now, I start timing how long does it take to 500 ml of dirty water to be filtrated.

Activated Carbon

The steps to create my product

These pictures that I drew on the board during ESL class. The purpose is to explain anyone who wants to know more about water filtration.

Why Filter Water?

Filtering water is a task worthy of effort, especially if you have the health and safety of your family in mind. After all, the quality of water these days cannot be trusted, especially in areas with a lot of industrial activities. A lot of contaminants are usually detected in most water supply system.



With such danger, it is important that you take the necessary precautions to make sure the water you use is clean and pure. But don’t worry, this does not necessarily have to cost you a lot. In fact, you can make your own water filter. Here's the picture:

Water Filtration Process

Waste water and water from most natural resources must be cleaned before becoming available for general everyday use. Water treatment plants take potential drinking water through aeration, coagulation, sedimentation, filtration and disinfection process before it can be available for human consumption.

1. Filtration Process

   • The steps that make up the water filtration process are pre-filtration, sediment filtration, carbon block filtration and ultraviolet treatment.

   Pre-Filtration

   • The pre-filtration step removes all rock, mud, feces and other large debris from incoming water.

   
   

   
   

   
   

   
   

   Sediment Filtration

   • In this step the water passes through a sediment filter. The sediment filter has smaller pores for the removal of smaller debris like sand, dirt and bugs.

   Carbon Block Filtration

   • Block of Activated Carbon from Carbon Filter
     

     This step incorporates and activated carbon filter to induce carbon bonding. The carbon bonding works to cleanse the water of pesticides, herbicides, cleaners and other chemical impurities.

   Ultraviolet Treatment

   • This final step uses high levels of ultraviolet light to kill harmful microorganisms like bacteria, viruses, fungi and algae.
