Lesson 3

Presentation

After completing the practical work in this lesson, ask the groups to present the results of the project to their classmates. In this project, you can hold a team competition. Be a judge when evaluating the quality of filtered water: hold a piece of white paper to the filtered water and check if there are any solid particles and foreign color. The winning team has the cleanest water bottle. We wish all teams good luck!

Conclusion

Investigating one of the global problems as water pollution, students were asked to conduct an experiment and make a water purification plant in order to solve this issue. Moreover, the students made their own filtration plant that can purify contaminated water and made a visual analysis of the water.
