Class V
Changing States of Matter
Changing states of matter occur when matter loses or absorbs energy. When a substance absorbs energy the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough that they change form. These concepts were explained with a hands-on activity.
Class VI and VII
Making Paper Planes
The concept of aerodynamics was discussed with the activity of making paper planes. The scientific principles of thrust, drag, lift, low pressure and high pressure were explained.
