Cambios físicos o químicos?


Science is a fascinating subject, and teachers must transmit this message to students through the elaboration of catchy activities that learners would not forget. Fifth graders have studied physical and nonphysical properties of matter. Likewise, children have analyzed examples of physical and chemical changes of matter at the lab. This time, learners worked with chalk to experiment how these materials suffer physical changes when broken by people. Students rearranged the broken parts of chalk, so they could visualized how physical changes of matter do not change the type of matter in terms of its nature. Moreover, chalk was mixed with some substances at the lab in order to see how it transformed into a new material because of the chemical change. This lab made students comprehend content easily.
