We were challenged to create water filters from things we had at home.
All groups were given disinfected aquarium gravel to act as the coagulate. One group used foil and kitchen roll, one group used a Brita filter and a hole in the bottle cap, another group used a sieve, kitchen roll and tea bags and the last group used just a tea bag!
The most successful group used the sieve (to filter out the rocks and debris), kitchen roll (to filter smaller particles out), and tea bags (to further filter the water). Although the water was much clearer in comparison and there were no leaves or visible dirt, we know that the water was still not safe to drink because we didn't add a disinfectant to the water.
We learnt that it is very difficult to filter water on a small or domestic scale without the correct technology which when we searched online for, we saw that it can be very expensive. This is a problem for lots of people around the world because they cannot afford the appropriate technology. This means that they have to drink dirty and unsafe water, leading to lots of diseases.
After this experiment, we have pledged to conserve water by taking shorter showers, to only use a full washing machine, turn off the tap when brushing our team amongst more.
