Question 2

Jaden is building a simple circuit to light a small LED. He needs three items and wants to know which can carry electricity and which cannot. He has: 1) a strip of aluminum foil, 2) a dry kitchen sponge, 3) a glass jar filled with water that has a pinch of table salt dissolved in it. Which statement correctly classifies each material as a conductor or an insulator and gives the right reason?

Accepted Answer

The aluminum foil is a conductor because metals let electric charge move freely; the dry sponge is an insulator because it has no water to let charge flow; the salty water is a conductor because the dissolved salt creates ions that can carry charge.

Answer

The aluminum foil is a conductor because it looks shiny; the dry sponge is a conductor because its pores let electricity pass; the salty water is an insulator because liquids block electricity.

Answer

The aluminum foil is an insulator because thin metal sheets block electricity; the dry sponge is an insulator because it is dry; the salty water is a conductor because all water conducts electricity.

Answer

The aluminum foil is a conductor because metals are good conductors; the dry sponge is an insulator because it is dry; the salty water is an insulator because water is not a metal.

Question 3

Lily is building three different windows for her dollhouse. She wants: (1) a window that lets her see the whole scene clearly, (2) a window that lets light through but makes objects look blurry, and (3) a window that stops light completely. She has three sheets: a clear acetate sheet, a sheet of waxed paper, and a piece of cardboard. Which group of sentences correctly uses the words transparent, translucent, and opaque to describe each sheet for Lily’s needs?

Accepted Answer

The clear acetate is transparent, so Lily can see the whole scene clearly through it. The waxed paper is translucent, allowing light in but blurring the view. The cardboard is opaque, blocking light completely.

Answer

The clear acetate is transparent, so Lily can see the whole scene clearly through it. The waxed paper is opaque, stopping light completely. The cardboard is translucent, letting light in but blurring the view.

Answer

The clear acetate is translucent, letting light in but blurring the view. The waxed paper is transparent, so Lily can see the whole scene clearly through it. The cardboard is opaque, blocking light completely.

Answer

The clear acetate is opaque, stopping light completely. The waxed paper is translucent, allowing light in but blurring the view. The cardboard is transparent, so Lily can see the whole scene clearly through it.
