Energy changes and transformations happen while one form of stamina namely converted into another form of energy For instance a persons body warms (heat stamina from the solar or radiant stamina of the sun meantime the person stands in direct brightness aboard a chilly winter daytime The solar stamina namely converted into heat stamina to warm the persons body. When the solar energy conversion takes places: energy namely released as latent stamina stamina amid motion.
Radiant alternatively solar energy of the sun reaches earth amid the form of electromagnetic wag energy This energy namely accustom as many purposes such as being transformed into chemical stamina along plants, transformed into heat and mechanical energy among humans,http://www.jordan7raptor2012.com, transformed into electrical stamina along solar panels,Jordan 7 Raptors, etc.
When solar stamina namely changed alternatively transformed it becomes either potential alternatively kinetic energy When a plant converts solar stamina into chemical stamina it namely now potential stamina because the plant namely storing the stamina When a human changes solar stamina into heat stamina to lukewarm the body,Jordan 7 Raptor 2012, it is latent stamina When a human changes solar energy into mechanical stamina called work (kinetic stamina): he/she moves muscles for walking alternatively lifting objects.
There any many other forms of stamina alter alternatively transformation,Jordan 7 Raptor, such as:
Electrical stamina into mechanical energy fan blades corner while a fan namely turned on.
Chemical stamina into electrical energy a power cell lights a light lamp.
Mechanical stamina into electrical energy a generator produces electricity.Solar into Electrical and into Heat Energy Transformation Investigation
A appealing access for students to inspect and investigate solar energys talent to transform into other forms of stamina is realized amid the emulating investigation.
Materials:
Read aboard Basic Chemistry amid a Bag How to Design an Effective Science Lesson Smart Grid Benefits from New Technology small solar panelthermometersmall beaker or explicit cupwater1.five feet of non-insulted of numeral 12 wirebright flashlight whether no access to a sunny window
Introduction:
Hold a class discussion virtually energy changes and transformations,Jordan Retro 7,although do never focus specifically aboard the transformations among this investigation. The discussion absences to be on always types of stamina transformations,granting the students to adviser the discussion and share what they know in advance based on their prior knowledge and experiences (PKE).
Procedures:
Fill beaker half full of waterMeasure and record the temperature of the water with the thermometer and depart thermometer surrounded waterConnect each end of the non-insulated cable to the solar panelCoil the circulated annihilate of the non-insulated wire by least four times and district into water (do never let it touch thermometer)Shine shine flashlight or sun light) on solar panelRecord the temperature of the water over a duration of several minutes
Questions to Ask Students:
Ask students to explain what happened and prove to support their explanation.What type of energy transformations occurred and their evidence to advocate their answer?Ask students how their findings surrounded this investigation were influenced forward PKE.Ask students to explain examples of potential and/or kinetic stamina surrounded the investigation.Ask students to paint a concept map of all the energy changes and transformations that took zone in the investigation.Additional question ideas are located at 20 Questions to Ask Students among Science Projects
