Answer ! d: kate gathered three boxes of the same size made of different materials: glass, clear, plastic, and alunium painted black. she placed them on a window sill in the sun for an hour and then measured the waremth if air in each box. in this experiment, the types of box materials are an a. constant variable b control c dependent variable d independent variable

B control because they dont change in the experiment so they are controlled

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
