How did you work with your group to brainstorm?
–> In the brainstorming section, as a group, we decided to sketch down how we think the machine will look like and how it will work. Every member has different ideas and in a team, which selected the best ideas from each person and turned all of those ideas into a sketch that we are all agree with. During the brainstorming time, I told them my ideas and drew down the machine that I imagined. The agreed with it and also added more ideas.
What ideas can you offer?
–> My ideas were using the big plastic bottle that contained 1,5 litres of water become the containers of the river water. In this machine, at first, my ideas were, we are going to have two stations only because it might take lots of space if we have too many stations. Also, one of my ideas was using fire from natural energy to get away the bacteria because, in the constraints, the place that we going to put our experiment would not have enough electric to run the machine so we can only use resources from the nature of solar energy.
What are your group’s next steps?
–> Our next step is to start working on making each station and bringing materials that we need. We need to cut out the plastic bottle to create containers. Also, finding ways to boil the water by using solar power but still wouldn’t waste wood.
What should you bring?
–> We need to bring cotton, the large and medium size of the plastic bottle and clothes.
What methods (chemical, mechanical, biological, or natural) are you using in your design?
–> In our design, our method is natural by using the resource from the sun to boil the water without wasting wood or giving bad gasses into the air. To use this energy, we are deciding on making a solar oven out of pizza box.
What steps do you need to do tomorrow to improve or test your design(systematic testing)?
–> The step that we need to improve is the first station where we are trying to get all of the soil out of the water. We need to glue the bottle again because the water spill outside. Also, we need to work on how to connect out stations together.
What is your prediction of how it will work? Add a picture to show your model.
–> My prediction is that it will work probably and like how we have planned because all of the works is going successfully so I believe it will work.
What did your group do today?
Today, we have continued working on our machine and we started to make the solar oven. I was the that responsible for the oven and others helped me. I used shoe’s box to create it. Zi Tao, Kyle and Antonio worked on the connection of each station by using a part of the water hose.
What methods did you use to remove bacteria?
The methods that we used to remove bacteria is boiling the water as heat can get away of the bacteria in the liquid that we have.
What methods did you use to remove salt?
For removing the salt, we haven’t really think about removing the salt so this is one of the most important thing that we need to think about on next class.
What methods did you use to remove sediment?
To remove the sediments, we have used clothes to remove it. The reason we use clothes is because as clothes have little, tiny hole where the water can go through but not the sediments so it helps getting rid off the sediments. Also, to make sure that there is no more sediment in the water, we have decided to put two layers of clothes and coffee drip filter. The coffee drip filter is sort of similar to the clothes that it has tiny holes but instead the material is fabric, it is make out of inox.
Would you drink your water after it has passed through your filter system? Why or why not?
I would drink the water that has passed through my filter because I believe that it is clean and fine to drink. I trust my work and I want to show that my team succeed.
