An ocean current is a seasonal directed movement of seawater generated by forces acting upon this mean flow, such as breaking waves, wind, the coriolis effect, cabbeling, temperature and salinity differences, while tides are caused by the gravitational pull of the sun and moon. The world ocean circulation experiment (woce) was a component of the international world climate research program, and aimed to establish the role of the world ocean in the earth's climate system. What do you notice about the result that is similar to the kirchhoff's voltage law experiment kirchhoff's current law is to currents summing at a point (node) or percentage, of the total current this is why a parallel resistor circuit is often called a current divider. This ocean currents experiment helps explain more about how sailors navigate and how the currents affect navigation.
Experiment vi voltage, current and resistance introduction our world is filled with devices that contain electrical circuits in which various voltage. My son checked out the book awesome ocean science by cindy littlefield, and decided to try the experiment on deep-water currents (pg 32) in this experiment, you fill a baking dish with tap water, put an ice pack in one end, drop one drop of food coloring in the water near the ice pack, and. Convection current april 14, 2014 10:12 am 'weather' or not the science of weather affects all of us every day, and particularly at this time of year seems to. Experiment 17: kirchho 's laws for circuits 95 questions 1 explain what e ect the dmm will have on the cir-cuit when inserted to measure current. Buy experiments with alternate currents of high potential and high frequency on amazoncom free shipping on qualified orders.
Youtube's best convection currents video science demonstration for your students - duration: 3:05 science up with the singing zoologist 104,683 views. For anyone who ever wondered 'why', live science makes every day a little more interesting by illuminating the amazing world around us. Ac circuit experiment this lab deals with circuits involving resistors, capacitors and inductors in which the currents and voltages vary sinusoidally in time equipment 1 function generator (pc scope software) 1 digital multimeter and leads 1. We used the current balance to establish the unit of current, the ampere, by comparing the magnetic force (associated with a pair of currents) with the gravitational force (on measured masses. Invisible convection currents are revealed using a very colorful demonstration hot air balloons rise because warm air in a balloon is lighter and less dense than cold air similarly, warm water is lighter or less dense than cold water when the bottle of warm water is placed on top of the cold. Voltage and current division lab reportpdf - free download as pdf file (pdf), text file (txt) or read online for free voltage and current division lab report.
View notes - lab report 3 from phy 210 at pima cc experiment 3: introduction to electrical circuits david martinez-rivera date performed: september 24, 2013 12:00pm psy 122in 13622 professor. Rip currents: a field experiment and numerical model 1 background 11 motivation rip currents are approximately shore normal seaward directed flows that typically reach speeds up to 1 m/s, and have been reported as high as 2 m/s in mega-rips such as at palm beach, australia [short, 1985. Ocean science activities repeat the experiment ocean currents the following activities help children understand two key causes of ocean currents-wind and variations in temperature ocean motion you will need the following materials. Waves and currents introduction to waves (grades k-2) in this lesson, students experiment with creating waves of varying sizes and learn about wave height and wavelength. Ones that are really experiments and really happening (or likely to happen.
What is density how does temperature and salt concentration affect the density of ocean water how does density create ocean currents. Go with the flow means, relax let the current of life's river carry you along but, in life, that is not always the best way to get where you want to go in this game, you go with the flow only after you have fixed the currents to take you where you want to go where do you.
Science news online features daily news, blogs, feature stories, reviews and more in all disciplines of science, as well as science news magazine archives back to 1924. Water currents purpose in water density associated with temperature and salinity play an important role in in shaping ocean currents procedure set up several hours before you need to begin he experiment.
