Water Filtration Fun
Hosted by: UT Austin Kumar Research Group
Visit our Booth: Saturday, February 27, 2021, 12 p.m. - 4 p.m.
Recommended Grades: 6th, 7th, 8th
The Challenge: Use household materials to create a water filter that can clean your dirty water the best.
- Start with a funnel or a plastic bottle with the bottom cut off.
- Create dirty water by mixing dirt from outside with water or adding other pollutants (pebbles, sand, shredded paper, etc).
- Fill the funnel/bottle with different household materials as your column packing.
- Test different packing materials to see what filters out your pollutants the best.
Video your dirty water before you filter it, as it goes through the filtration, and after it's been filtered. Tell us about your design and results and share on Flipgrid.
Watch the video on the Filtration Demo tab for a demo and explanation of this activity after you've tried it on your own.
- Funnel or plastic bottle with the bottom cut off
- Cup or other vessel to collect your filter flow through
- Pollutant materials: Dirt, pebbles, sand, shredded paper, food coloring, etc.
- Packing materials: fabric, cotton balls, rocks, sand, coffee filter, etc. Be creative!
How does this activity connect to STEM and today's Girl Day theme of Designing for Communities, People and Animals?
Water filtration is an important part of every community. Sometimes we take it for granted that we can turn on the faucet and clean, drinkable water comes out. But before it gets to you, several scientists and engineers worked to make it clean. Labs like the Kumar Research Group are constantly developing new membranes and filtration methods to help improve ways to get you clean water. Check out the other tab to see a demonstration of one of the real-life filtration technologies our lab is working on!

Description: Watch the water clear up right before your very eyes. Help us figure out how to make a column that can filter out dye from water. Using our Moringa seeds, we can try to filter food coloring from water.
- To get kids curious and interested in water purification and filtration
- To allow kids to participate in a hands-on activity
- To share a bit about our Moringa research project at an age-appropriate level
- What materials around your house could you use to filter dirt and debris from water?
- Do you think cotton balls can filter food coloring from water?
- What is the difference between the first filtration and the second filtration in the video? Why does one work better than the other?
Why might seeds have proteins that can stick to viruses and bacteria? Why would that be helpful to plants?
Kumar Research Group is interested in mimicking biological processes and materials at the molecular scale to develop materials and processes that bring the specificity and functionality of biological molecules and processes to engineering scales. We are very interested in improving current advanced separation systems used in the process, water, energy, and biotech industries with a heavy focus on industrial and municipal water reuse and desalination with a goal of making urban water cycles more sustainable.
