Elijah, Aria, and Charlotte are conducting an experiment in their physics class. They noticed that as they move electrons in a current, they create ____________________.

• a bar magnet.

• a gravitational force.

• a magnetic field.

• a broken, or short, circuit.

Jackson, Grace, and Olivia were doing their laundry. They noticed that their clothes in the dryer got charged. They realized this was due to _________________ as charges were wiped on and off pieces of clothing.

• friction

• conduction

• induction

• static discharge

Mason and Kai were experimenting in their physics lab. What happens when Mason moves electrons from his object to Kai's object through direct contact?

• friction

Evelyn, Isla, and Ava are working on a science project. They need to light up a bulb using a circuit. They realize that the _____ causes charges to move in the circuit, which is necessary for the bulb to light up.

• a load

• a switch

• a conductor

• battery

Arjun, Kai, and Henry were studying about magnetism. They learned that within a magnetized object, such as the fridge magnets they were playing with, there are tiny magnetic areas. These areas can be either aligned(organized) or unaligned(unorganized). They were curious to know what these areas are called. Can you help them? They are called ________________.

• magnetic fields.

• ferromagnets.

• magnetic poles.

• domains.

Daniel, Abigail, and Priya are working on a science project. They notice that when they connect a wire to a battery and a light bulb, the bulb lights up. They realize that the negative charges moving in the wire make up _______________ and provide energy to the light bulb.

• electric current

• light energy

• conduction

• Voltage

Maya, Elijah, and Scarlett were at a birthday party. Maya rubbed a balloon on her hair and stuck it to the wall. This happened because the friction involved in rubbing the balloon produced a static electric charge by transferring ____________.

• electrons.

• protons.

• atoms.

• molecules.

Lily, Emma, and Zoe were conducting a science experiment. They noticed that when they rubbed a balloon on their hair and then held it near a metal object, the static electricity on the balloon moved off. This phenomenon is known as______________________.

• friction.

• conduction.

• electric discharge.

• induction.
