Science experiment for kids using Snap Circuits
Goal 1 : To learn that pure water does not conduct electricity and salt water is a good conductor due to free ions.
Goal 2: Difference between a circuit in series and parallel.
Tool used : The Snap Circuits model SC-100 used in this experiment was purchased 4 or 5 years ago. It is a basic model which I felt was sufficient enough to keep the young kids engaged.
Description: I built a simple circuit in series with the glass of water completing it. Pure water being a bad conductor cuts off the flow of current which powers the fan in the circuit. I proceeded to add copious amounts of cooking salt to make it a good conductor because salt disintegrates into free ions which aid in flow of electricity that powers the fan.
In a parallel circuit, the current flowing through the fan is independent of the current flowing though water. This means that the presence of water (pure or salt) has little impact on powering the fan. However, the resistance of salt water indeed affects the speed of the fan (too much detail ☺️). #science#snapcircuits#homeschooling#homeschool#physics#physicstoy#electronicstoy#scienceexperiment#circuit#giftedandtalented#stemtoys#physicsisfun#snapcircuitsjr#stemgirls#stemboys#stemeducation#learningisfun#school#charterschools#educational#tinkeringstudio
