Reflection on Bloom’s project
What have you learnt about?
Water Filtration
What have you learnt about how you learn?
I started an Internet search on “How can we purify water using affordable materials?” I used one article and it said that we could make a simple water filtration by using materials around the house. I was surprised to read this comment as I found out the cost is just less than 100,000 rupiah.
I found that I am a visual learner and the print is more interesting when there is picture cues that help me understand what I am reading.
Comprehension
How can I compare dirty water with clean water?
I will form some questions related to cleanliness, time and cost.
Do an extensive research from the books, Internet and I will interview my science teachers like Ms Jane and Mr Justin.
Application
I drew some pictures and wrote a brief explanation on each picture in order to give people visualization how to make my water filtration. I recorded my steps and then I posted it on my edublog.

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 .

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.
