Experiment #2: Energy Changes (ENERGY)
Whenever I get my students to fold paper aeroplanes, especially the boys, their faces light up. They thought I am going to play something. Yes, they are right! I love to use every day activities and link them to Science concepts. It helps them remember better. As the old adage goes, “a picture paints a thousand words”. So, getting my students to see, feel, touch and “paint” images in their minds is my personal mission to help them grasp concepts in a fun way!
*CHILD: fold a paper aeroplane. If he/she does not know, google for a tutorial. Heaps of it. Choose the easiest one.
*CHILD: stand at a designated distance and get him/her to aim at a distance and throw. Watch how it lands. Repeat a few times. Vary the distance.
*OBSERVE: how each landing goes.
*LINK: Prior knowledge is needed.
Chemical Potential Energy, Kinetic Energy, Gravitational Potential Energy, Heat Energy, Sound Energy
*CHILD: guide child to think what energy changes has taken place as he/she aims and throws the paper aeroplane.
CPE (food from body) -> KE (moving paper aeroplane) -> GPE (paper aeroplane in air -> HE + SE (hits the wall) -> KE (paper aeroplane falling down) -> HE + SE (hits the ground)
*NOTE: answers may vary, according to how/what the question asks. In this case, children are required to list out the energy changes as specifically as possible.
*JOURNAL: encourage your child to create his/her own mindmap/journal/other forms of records.
