  • How can I construct a very simple model of a river(i.e. mouth, source) for young children?


  • Here is a river system diagram http://www.nationalgeographic.com/geographyaction/ax/PDF16_RiverSystem1.pdf Here is a nice animation of a river from the source to the mouth. http://www.nationalgeographic.com/geographyaction/ga01.html ------------------------------------------------------ Here are step-by-step instructions with pictures for making a miniature river basin. The finished model shows the main features of a river; source, tributary, confluence and mouth. St Peter's Church of England High School http://www.st-petershigh.stoke.sch.uk/departments/geography/pupils%27%20work/Y7riverbasin.htm Here are some of the finished models http://www.geography.ndo.co.uk/riverbasins.htm http://www.geography.ndo.co.uk/images/riverbasins3.jpg ------------------------------------------------------ You can also create a very simple model river with clay either on a sheet of plywood, or on a plastic or metal tray. ?Start upstream and build up enough clay to represent mountains. Downstream, the land should flatten out and lead to the mouth of your river. Use the river system diagram as a guide.? Source: National Geographic http://www.nationalgeographic.com/geographyaction/ga29.html River system diagram http://www.nationalgeographic.com/geographyaction/ax/PDF16_RiverSystem1.pdf Place plastic wrap over the clay, providing a way for water to flow. Tilt the project as needed to aid water flow. Using the eyedropper, drop water down the model, starting at the source of the river:. Watch the water's path. ------------------------------------------------------ Here is a teacher?s plan with instructions illustrating the course of a river RESOURCES REQUIRED A plastic tray 2m x 1m x 6cm (minimum size) with one of the shorter sides removed. Sand. A Watering can with a rose. A plastic bucket. 2 house bricks. A bench or old table to place the plastic tray on This is activity four: scroll down to the bottom of the page for instructions: http://www.kented.org.uk/ngfl/rivers/Teacher%20Plans/whatisariver.htm ------------------------------------------------------ On this webpage http://www.uen.org/stream/html/3lesson2.html you will find a river model http://www.uen.org/images/stream/RIVERMODEL.gif and instructions http://www.uen.org/stream/html/instructions.html for making the river model. This was taken from the Third Grade Lesson Plan called Old Man River. http://www.uen.org/stream/html/third.html Lessons created and contributed by Chris Davis, Hillcrest Elementary ------------------------------------------------------ ACTIVITY ELEVEN : 3D River Models made of paper mache http://www.kented.org.uk/ngfl/rivers/Teacher%20Plans/whatarethefeaturesofrivers.htm ------------------------------------------------------ Watershed in a box http://clean-water.uwex.edu/wav/otherwav/winbox.pdf ------------------------------------------------------ A river model from PBS http://www.pbs.org/wgbh/nova/teachers/activities/pdf/2307_flood.pdf http://www.pbs.org/wgbh/nova/teachers/activities/2307_flood_01.html ------------------------------------------------------ Search Criteria: Create a river model Construct a river model Build a river model Activities OR activity river model River model +clay River model tray clay I hope you find this helpful!
