plastic wrap

Question 11

Electricity and magnetism are connected to each other. Electricity can produce magnetism. When an electric current flows through a wire, the current creates a very small magnetic field.

Accepted Answer

True

Answer

False

Question 12

Question 12.

Accepted Answer

Option A is correct

Answer

B.

Question 13

Accepted Answer

step 5: Connect a test material to the open ends of wire 1 and wire 3.

step 6: Make observations, and repeat step 5 with a different test material.

conclusion: If the bulb lights up, the material is a conductor. If the bulb does not light up, the material

is an insulator.

Answer

step 5: Connect a test material to the open ends of wire 1 and wire 3.

step 6: Make observations, and repeat step 5 with a different test material.

conclusion: If the bulb lights up, the material is an insulator. If the bulb does not light up, the material

is a conductor.

Answer

step 5: Connect the open ends of wire 1 and wire 3 to each other to complete the circuit.

step 6: Touch a test material to the completed circuit, and record observations.

conclusion: If the bulb lights up, the material is an insulator. If the bulb does not light up, the material

is a conductor.

Answer

step 5: Connect the open ends of wire 1 and wire 3 to each other to complete the circuit.

step 6: Touch a test material to the completed circuit, and record observations.

conclusion: If the bulb lights up, the material is a conductor. If the bulb does not light up, the material

is an insulator.

Question 14

Accepted Answer

Magnet 1 should be used to pick up magnetic objects in one location and drop them off in another location because temporary magnets can be turned on and off.

Accepted Answer

Magnet 2 should be used to pick up magnetic objects in places where there is no power supply because permanent magnets do not run out of energy.

Answer

Magnet 1 should be used to pick up many small magnetic objects at once because the temporary magnet can pick up as many objects as the permanent magnet can.

Answer

Magnet 1 can be used in all the ways magnet 2 is used because temporary magnets can be made stronger or weaker and permanent magnets cannot.

Answer

Magnet 2 should be used to pick up large magnetic objects because permanent magnets are stronger than temporary magnets.

Question 15

A student is investigating chemical changes by using different materials. Which investigation would provide evidence of a chemical change and why?

Accepted Answer

Combining two liquids that give off heat and gas would provide evidence of a chemical change because

the particles react to make a new material with different properties.

Answer

Melting a solid with fire would provide evidence of a chemical change because the solid would change

shape.

Answer

Cutting cardboard into many smaller pieces would provide evidence of a chemical change because the

pieces cannot be put back together.

Answer

Placing a solid into hot water and stirring while the solid dissolves would provide evidence of a

chemical change because the dissolved material is lost.

Question 16

Students are investigating chemical changes that occur in different materials. Which TWO investigations would provide evidence of a chemical change?

Accepted Answer

Using a hot plate to heat a solid until it changes color and releases an odor would provide evidence of

a chemical change because the particles cannot be changed back.

Accepted Answer

Placing two different liquids together in a beaker and observing that a solid forms when they mix would

provide evidence of a chemical change because a new material is formed.

Answer

Placing a liquid in a freezer until the liquid becomes a solid would provide evidence of a chemical

change because the state of matter changes.

Answer

Using a saw to cut a solid into two different pieces would provide evidence of a chemical change

because the pieces cannot be put back together.

Answer

Placing a mixture containing a solid and a liquid on a windowsill and letting the liquid evaporate would

provide evidence of a chemical change because the evaporated material is lost.

Question 17
