5th Grade Science Review

Front

What components are needed to create a simple electrical circuit?

Back

A battery, connecting wires, and at least one light bulb.

Front

What is the purpose of a switch in an electrical circuit?

Back

A switch controls the flow of electricity, allowing the circuit to be opened (off) or closed (on).

Front

What happens to light bulbs in a series circuit if one bulb burns out?

Back

All light bulbs in a series circuit will go out because the circuit is broken.

Front

What is the difference between soluble and insoluble substances?

Back

Soluble substances can dissolve in water, while insoluble substances cannot.

Front

Which common household substances are soluble in water?

Back

Drink mix, sugar, and salt are examples of substances that are soluble in water.

Front

What is erosion in the context of geology?

Back

Erosion is the process by which rock and soil are moved from one place to another, often by wind, water, or ice.

Front

What is the effect of adding more light bulbs in a series circuit?

Back

Adding more light bulbs in a series circuit increases the total resistance, which can cause the bulbs to be dimmer.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where there are multiple paths for electricity to flow, allowing some components to operate independently.

Front

How does the arrangement of light bulbs in a parallel circuit affect their brightness?

Back

In a parallel circuit, each light bulb receives the full voltage, so they all shine at full brightness regardless of how many bulbs are present.

Front

What is the role of a battery in an electrical circuit?

Back

A battery provides the electrical energy needed to power the circuit.
