Water Project Funded by EEC0808696 Clean Drinking Water

Water Project Funded by EEC-0808696 Clean Drinking Water Scott. Ketcham 1, Sara. Bagley 2, , Dr. George Sorial, Hafiz Salih University of Cincinnati, Erpenbeck Elementary, University of Cincinnati 9 th Grade Activity 4 th Grade Activity Abstract Students will design , create , and investigate with a workable water filter that will clean polluated water. These lessons are inquiry driven to allow students the ability to use observations to see actual processes occurring connected to the nature of matter. Objectives 1. Work cooperatively in groups to come up with a filter design 2. Construct a water filter that is functional 3. Test the functionality of the device Standards Study properties of matter and physical changes through direct observations Misconceptions • Water cycle (4 th) • Ground /surface water (4 th) • Kinetic molecular theory of matter (9 th) • Phase Changes (9 th) • Pure substance/ mixtures (9 th) • p. H scale (9 th) problem of cleaning water Andrea Burrows Dr. Anant Kukreti, Hafiz Salih, Dr. George Sorial, and Lijuan Sang, • Performance • Common (4 th) • Science notebooks (4 th) • Entrance/ Exit slips (4 th) • Best filter debate one power point slide (9 th) • Group filter diagram (9 th) • Observation sheet/data table (9 th) • Questions based off data (9 th) • KWOL (9 th) (4 th) Background Application- investigate the Acknowledgements Assessment • Students understand rainfall in terms of gravity but do not make the connection of condensation , water cycle. (4 th) • Belief that matter is gained or lost as a result of chemical and physical changes (9 th/10 th) • Mixtures and solutions are chemical changes (9 th/10 th) Careers-chemists, environmental and civil engineers, technologists , hydro-geologist Society- with increasing human population there is a need for more efficient water treatment Conclusion Once over, students should have an understanding of chemical and physical changes, and a stronger use of observational skills and establishing conclusions based off of them. Modifications Ø Fit lesson to standards for specific grade level. ØAccommodations made for special needs students per Individual Education Plan. Students will try and clean dirty water, by selected materials to utilize both physical and chemical changes. Objectives 1. Create a water filter that will clean water based on their knowledge of mixtures 2. Identify chemical and physical changes associated with cleaning water 3. Use observations and the p. H scale to determine the purity of water. Standards Nature of Matter • Investigate the properties of pure substances and mixtures Science and Technology • Identify a problem or need, propose designs and choose among alternative solutions for the problem.
