STEAM PROJECT #1
MAKE YOUR OWN WATER FILTER AND OBTAIN COLORLESS WATER
Water from lakes and rivers often has contaminants that make it unfit for drinking. The water may contain dirt, rocks and other objects that can be easily identified. Water may also contain bacteria and other microscopic organisms that cannot be seen easily. For these reasons, water that is delivered to our homes must go through a water treatment process. This is typically a five-part process that consists of aeration, coagulation, sedimentation, filtration and disinfection. This activity is only concerned with filtration, which removes most but not all of the impurities from the water. Make sure students know that in this activity the filtered water is still unfit to drink.
Purpose of the project:
- Design a prototype which uses methods to filter water using ordinary materials, while also considering the designs’ material and cost efficiencies.
- Learn about the importance of water and its role in our everyday lives.
- Understand what must occur each day so that they can have clean water.
Civil, environmental , materials and mechanical engineers all contribute to developing technologies and systems to purify unclean water. Purifying water can be done easily if it is a small amount that is fairly clean, but larger amounts that are very polluted are much more complicated.
Typical steps for full water treatment include
- Understanding of how filtration works. (Science)
- Creative design methods. (Engineering)
- Problem solving. (Science)
- How much filter water can you get in one hour with different filters? (Mathematics)
- Video Production of the step by step and application. Using excel to produce data tables and
- 1 liter of water prepared in advance with soil and sand in it until it is thin but relatively opaque
- List the materials you will use in your design. (you have to build 3 different ones and test which works the best. This will be your prototype.
An example for your motivation:
One of our most valuable and often overlooked resources is water. We can survive for a few weeks without food, but only a few days without water. Having clean water to drink is a luxury. The water that eventually comes out of our faucets sometimes does not start off being safe to drink. In most cases, it has gone through a water treatment plant designed by engineers prior to reaching our faucets.
First step. How to build your own filter.
Second Step: Taking out Turbidity
Now you do it:
- Engineering Challenge: You have been hired by Miami Dade Water and Sewer Department. With the ongoing hurricane season not enough water is available for all the things we need to supply – people, animals and plants. You will collect a sample of the dirty water and design a filter with household materials to obtain clean water. DO NOT DRINK THE WATER.
- Math Challenge: You need to design a filter prototype that is affordable for most families in Miami and that fulfill the needs of water for daily use (toilets, washing clothing, cleaning the house, etc). (no more than 10 dollars per filter)
- You need to submit a video showing the step by step so as to a sketch of the design labelled with the materials you used.
You should use gloves and goggles while working with dirty water. Do not drink the filtered water under any circumstance)
- What was the best filtering agent and why?
- What are other ways we purify our water?
- Design a package for your “clean” water filter.
- Design a LOGO for your product.
For further information and good examples, please watch the following videos.
Presentation of the WATER FILTER VIDEO PROJECT (AT LEAST 3 LAB GRADES)
You must present that day:
- YOUR PROTOTYPE
- IN A SUITABLE PACKAGING
- WITH THE LOGO OF YOUR COMPANY
- AND A QR CODE outside the packaging that links to your video in YouTube.
- A VIDEO IN YouTube which WILL NOT OVERPASS 5 MINUTES and will include
- send me the LINK TO THE VIDEO to firstname.lastname@example.org
- Title of the project (with the FIRST NAME ONLY of the authors and Last name initials)
- Materials (as captions)
- Procedures (how to setup the prototype filter)
- Data tables (measuring the volume or measuring time)
- USE ONLY METRIC SYSTEM. DO NOT USE OUNCES OR CUPS. IF YOU MAKE UP THE NUMBERS, YOU WILL RECEIVE A LOWER GRADE!
- complete setup (explaining in the video how the filter works
- (which household activities can be done using your filtered water?)
- which improvements could you do to your prototype in future investigations?
- which are the compounds or substances that passed through your filter and do not make it suitable for drinking?
- how could you resolve this problem?
- You can add bloopers at the end of the video.
