Year 6 Unit 1.1 Electricity

Electricity is a type of energy that powers many of our daily appliances. These appliances convert electricity into different forms of energy such as heat, light, and movement. Take a look at the pictures of some electrical appliances we use every day below. Put a checkmark ( / ) next to the energy conversion that occurs in each appliance.

Here is a brief passage about electricity sources. Please read the sentences carefully and fill in the blanks with the correct answers using the given words.

Electricity that powers our homes and factories comes from two main sources: mains electricity and electric cells. Mains electricity is generated by power stations using a variety of fuel sources, including coal, natural gas, hydropower, solar power, wind, and nuclear energy. In Brunei Darussalam, natural gas is a primary source of fuel for power stations. Please refer to the figures below for examples of power sources, and answer the following questions.

Please review the electricity distribution system diagram below and answer the following questions.

Could you clarify where electricity is generated?

Please review the electricity distribution system diagram below and answer the following questions.

Could you please explain how electricity flows from the power station?

Please review the electricity distribution system diagram below and answer the following questions.

How does electricity get to homes, factories, and warehouses?

Electricity can be produced by electric cells, like dry cells that are commonly used in many households. Please read the description of dry cells and answer the questions below.

Dry cells are small batteries of various sizes that produce electricity quickly and have a longer lifespan. They are perfect for powering small electronic devices, such as toys, flashlights, radios, cameras, and mobile phones. Dry cells have a low impact on the environment and are also cost-effective.

Question.

Why are dry cells good for small devices like toys and torches?

Question.

What is the main advantage of dry cells for small electronic devices?

Electricity can also be produced by electric cells. Solar cells are a common source of electricity for homes. Please read the description of solar cells and answer the questions below.

Solar cells use sunlight to create electricity. When sunlight hits a solar cell, it turns into electric energy. One solar cell doesn’t produce much electricity, but many solar cells put together into solar panels can provide enough power to supply electricity to a house, building, or outdoor space.

Questions

What occurs to light energy within the solar cells?

Questions

Why don’t solar cells work in the dark?

An electric circuit is a way for electricity to move. A simple electric circuit has a cell or battery, wires, and electrical parts like a bulb. There are two types of electric circuits: closed and open circuits. Look at the electric circuits below and answer the questions.

 An electric circuit typically includes a switch, which can come in various types. The circuits depicted below illustrate two types of switches, with Circuit A showing the switch in the ‘ON‘ position and Circuit B showing the switch in the ‘OFF’ position. Please use these circuits to answer the following questions.

To make electrical circuits, we use simple symbols for the different electrical parts we need. Here are some examples of these parts and their symbols. Just drag and drop each part to its matching symbol in the table.

To create circuit diagrams, we use symbols to represent the electrical components present in the circuit. Here are some examples of circuit diagrams. Please answer the following questions.

Question

Please drag each circuit to its corresponding circuit diagram.

Question

Why isn’t the bulb in circuit B lighting up?

We have the option to increase the number of dry cells or bulbs within a circuit. In circuit C, four electrical components – two dry cells, a switch, and a bulb – are connected one after another. This type of connection is called a series connection. Please refer to the circuit diagram below and use it to answer the following questions.

Questions:-

To connect two dry cells in a circuit, what is the proper method?

This type of connection is called a series connection. Please refer to the circuit diagram below and use it to answer the following questions.

Questions:-

 In this context, a cell is represented by a long thin line and a short thick line. Can you clarify what the long thin line specifically represents?

We have the option to increase the number of dry cells or bulbs within a circuit. In circuit C, four electrical components – two dry cells, a switch, and a bulb – are connected one after another. This type of connection is called a series connection. Please refer to the circuit diagram below and use it to answer the following questions.

In a series circuit, electricity flows through a single complete path. It is important to note that all four circuit diagrams (P, Q, R, and S) shown below are considered closed or complete circuits. Circuit S, however, is a parallel circuit with two complete paths for electricity to flow. Please carefully examine the circuit diagrams and provide answers to the following questions.

Certain materials are able to conduct electricity, while others cannot. Materials that are able to conduct electricity are called conductors, whereas materials that are not able to conduct electricity are called non-conductors. To determine whether a material is a conductor or a non-conductor, an electrical circuit, as shown below, can be set up. The materials listed below can be tested to determine which are conductors and which are non-conductors. Please fill out the tables below.

Electricity in a household can pose serious risks if not handled properly. This is due to the potential for shocks, fires, and even fatalities. The following pictures demonstrate safety precautions to take when using electricity. Please match each safety precaution to its corresponding picture.
