Water Project Clean Drinking Water

1. Funded by EEC-0808696 Scott. Ketcham1, Sara. Bagley2, ,Dr. George Sorial, Hafiz Salih University of Cincinnati, Erpenbeck Elementary, University of Cincinnati, University of Cincinnati 4th Grade Activity Students will design , create , and investigate with a workable water filter that will clean polluated water. Abstract These lessons are inquiry driven to allow students the ability to use observations to see actual processes occurring connected to the nature of matter. 9th Grade Activity Students will try and clean dirty water, by selected materials to utilize both physical and chemical changes. • Misconceptions • Students understand rainfall in terms of gravity but do not make the connection of condensation , water cycle. (4th) • Belief that matter is gained or lost as a result of chemical and physical changes (9th/10th) • Mixtures and solutions are chemical changes (9th/10th) Water Project Clean Drinking Water • Objectives • Work cooperatively in groups to come up with a filter design • Construct a water filter that is functional • Test the functionality of the device • Assessment • Performance (4th) • Common (4th) • Science notebooks (4th) • Entrance/ Exit slips (4th) • Best filter debate one power point slide (9th) • Group filter diagram (9th) • Observation sheet/data table (9th) • Questions based off data (9th) • KWOL (9th) Objectives Create a water filter that will clean water based on their knowledge of mixtures Identify chemical and physical changes associated with cleaning water Use observations and the pH scale to determine the purity of water. Standards Study properties of matter and physical changes through direct observations • Background • Water cycle (4th) • Ground /surface water (4th) • Kinetic molecular theory of matter (9th) • Phase Changes (9th) • Pure substance/ mixtures (9th) • pH scale (9th) • 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. 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. Application- investigate the problem of cleaning water Careers-chemists, environmental and civil engineers, technologists , hydro-geologist Society- with increasing human population there is a need for more efficient water treatment Acknowledgements Andrea Burrows Dr. Anant Kukreti, Hafiz Salih, Dr. George Sorial, and Lijuan Sang, • Modifications • Fit lesson to standards for specific grade level. • Accommodations made for special needs students per Individual Education Plan.
