Build Water Rockets Explain how they work and ask the students which of Newton’s laws apply to them. You should talk about what forces are acting on the water rocket to make it move (talk conceptually about the idea of a free body diagram). You should have the force from the ejected propellant acting upwards‚ and the weight and air resistance acting downwards. Talk about how each law applies to the physics of the water rocket. Try to have the students identify which

Surface Water - Surface water is water on the surface of the planet such as in a stream‚ river‚ lake‚ wetland‚ or ocean. It can be contrasted with groundwater and atmospheric water. - Non-saline surface water is replenished by precipitation and by recruitment from ground-water. It is lost through evaporation‚ seepage into the ground where it becomes ground-water‚ used by plants for transpiration‚ abstracted by mankind for agriculture‚ living‚ industry etc. or discharged to the sea where it becomes

Complexometric Determination of Water Hardness by EDTA Titration Bonnie Abella Dr. Asmita Kane Budruk 2/09/2014 Abstract: the complexometric EDTA titration was used to determine the salt substance in the water. This technique for the unknown sample 154 produced a water hardness of 8.43 x105=mg/L CaCO3 from the collected data which corresponds to the typical value from the city of Tempe. Introduction When the water from the rain collects impurities by dissolving the
