Three states of matterThis experiment shows how water changes between its three states due to temperature. Ice melts when heated to become liquid water, then turns into vapor with continued heating. When the vapor touches a cold surface, it condenses back into water droplets.states of matter – solid......

Objective To illustrate how mass affects the gravitational force on objects, understand the difference between weight (mass × gravity) and gravitational force, and reinforce the concept that gravity acts equally on all objects while the force varies according to massMaterials Digital scale – spring......
