Important Message for Parents and Carers

Dear Parents and Carers,

The teachers of Globe Academy believe that Home Learning is an integral part of developing every student and ensuring that they reach their academic potential.

Home Learning is important because it is point where school and home come together. It serves as a window through which you can observe your children’s education and express positive attitudes towards your children about their education and progress. As children grow older, homework and the amount of time engaged in homework, increases in importance. For Globe Academy staff, homework is an opportunity to provide additional academic instruction and further extend your child’s learning.

The benefits of Home Learning for you and your child are as follows:

(1) Practice and participation in home learning tasks can improve your child’s achievement.

(2) When homework is completed accurately and to a good standard, not only will your child’s general knowledge and grades improve but your child will also increase their mastery of basic academic skills, such as reading, writing, spelling and mathematics, something Globe Academy is committed to.

(3) Your child’s ability to bring an assignment home, gather and organise necessary materials to complete the assignment, return the assignment and receive a level/grade, strengthens his or her sense of personal responsibility for their learning.

(4) Time management skills are learned and developed.

(5) Further, when homework proceeds smoothly it can become (4) a positive aspect of your relationship with your child.

(6) Home Learning offers schools an opportunity to let parents know what their children are learning and keeps parents informed about work being studied and completed in class time.

(7) Home Learning helps the Academy achieve their overall mission of improving your child’s achievement.

(8) Homework is the bridge that joins schools and parents. For parents there is the potential to gain a greater appreciation of your child’s education and achievement.

For these valid reasons we are asking that parents/carers work with us to ensure that your child completes their homework.

Your child will receive a homework booklet for each subject and we ask that all parents/carers ensure that the tasks in this booklet are completed on time and to a high standard. Together we can improve your child’s progress and attainment.

Please sign below to confirm your agreement to support Globe Academy by checking and ensuring your child completes their Home Learning Tasks each week. In addition please sign and comment if necessary, the Homework Record sheets also in this booklet.

Entry Level 1 Say that light surfaces reflect more infrared radiation than dark surfaces.

Entry Level 2 Explain that infrared radiation causes objects to heat up.

Entry Level 3 Link these ideas together and suggest a solution to clothing worn in the desert.

Homework 2:

L.O. Particles and Energy

The use of kinetic theory to explain the different states of matter.

The particles of solids, liquids and gases have different amounts of energy.

All substances, solids, liquids and gases, are made from particles.

Match the description to the correct diagram

Description Container showing particles

Thermal energy transfer

These methods of thermal energy involve particles. There are four different ways energy can be transferred by particles:

1. Conduction

The particles in a solid are

very close together

vibrate in one place

usually stay in a fixed pattern

The particles in a liquid are

close together

move in all directions

have no fixed pattern

The particles in a gas are

far apart

move very quickly in all directions

move all over the container

This is the process of transferring thermal energy through solid material without any visible

change in the motion (movement) of the particles of the material

2. Convection

This is the process of transferring thermal energy by the movement of the fluid (liquid or gas)

through which thermal energy is being transferred

3. Evaporation

This is the process of transferring thermal energy to a liquid causing the particles to be converted to a gas.

4. Condensation

This is the process of changing gas to a liquid.

Which process is responsible for the thermal energy transfer in each of the cases below?

Answer each one by using the word conduction, convection or radiation.

1. The handle of a saucepan heats up when the pan and the contents are placed

on a cooker hot plate ___________________________

2. An object near to a gas fire becomes warm _____________________

3. The air in a room warms up when an electric heater in the room is switched on

________________________________________

4. Thermal energy travels between two objects in space ___________________________

5. Thermal energy travels through a metal bar _________________________________

6. Thermal energy travels through water _____________________________________

Homework 4

L.O. How do we insulate our houses? Mid Term

Assessment Revision

Students must know that:

Heating and insulating buildings.

U-values measure how effective a material is as an insulator.

The lower the U-value, the better the material is as an insulator.

Heating and insulating buildings

The diagram shows some of the ways in which thermal energy can be lost from a house.

Complete the following sentences by using the words from the box below.

double glazing loft insulation draught-proofing curtains tank radiator

doors roof cavity windows floors insulated walls

Heat Loss

Thermal energy is lost through the r____________, w____________, w____________ and the

d_____________ and f____________. To reduce heat loss, a building can be i____________.

To reduce heat loss through the roof, l____________ i____________ can be used.

C____________ wall insulation cuts down energy loss through the walls.

By d____________-p____________ windows and doors, energy losses can also be reduced.

To further reduce energy loss, d____________ g____________ can be used; this will reduce

the heat lost through windows.

Thick c____________ can also reduce energy loss.

Thermostatic r____________ valves can be used to prevent a building from over-heating and

so save energy. Also, insulating pipes and the hot water t____________ can also reduce heat

loss.

What is a U Value?

The U Value is a measurement of the rate of heat loss through a material.

The lower the U Value the better an insulator the material is.

For example, a single glazed window with standard glass will have a U Value of 5.6, while a double glazed window with standard glass will have a U Value of 2.8, and a triple glazed window will have a U value of 1.8.

Single glazed

U Value 5.6

Poor insulator

Double glazed

U Value 2.8

Good insulator

Triple glazed

U Value 1.8

Excellent insulator

Put these types of insulation in order of their ‘U Value’.

The best insulator should be number 1 and the worst insulator should be number 7.

Homework 5 Units of Electricity

Power rating of an appliance

The power rating of an appliance tells you the rate at which it transfers energy.

The more powerful a device, the faster the rate at which it will transfer energy.

We measure the power of a device in watts (W) or kilowatts (kW).

1 Kilowatt is equal to 1000 Watts.

Draw a ring around the appliance that will use the most energy when switched on for one

hour.

2kW fire 300W television

60W fan 1kW toaster

What is the power rating of the appliance above? _________________________


The amount of electrical energy transformed depends on the p_______________ of the

appliance and the length of t_______________ for which it is switched on.

Heaters usually have a h_______________ power rating that the other e_______________

devices.

If you leave a light bulb s_______________ on when you are not using it, you will end up

paying for more units of electrical e_______________

The u_______________ of power is the watt or kilowatt.

Loudspeaker S____________ H____________

Wasted energy is eventually transferred to the surroundings, which become warmer.

Where might the ‘wasted heat’ energy be in these examples?

Cycling

Driving a car

Light bulb in torch

The wasted energy becomes increasingly spread out and so becomes less useful.

As the cyclist pedals her energy turns the wheels.

Friction between tyre and the road changes some of the

energy into wasted h___________ energy which is lost to

its surroundings.

C____________ energy from the burning fuel powers the

car engine. However some of the chemical energy

increases the temperature of the engine. This wasted

h______ energy is lost to its surroundings.

Chemical energy from the torch’s battery is transformed

to e______________ energy. The filament in the light

bulb glows as useful light energy and wasted h_____

energy. The wasted heat energy is lost to its surroundings.

Choose the correct word from each pair in the sentences below.

Heat from barbeque

Sound from police siren

The further the light travels from the lighthouse the

more spread out it becomes so the (more / less)

useful it is.

The further the heat travels from the barbeque to

the food, the more spread out it becomes so the

(more / less) useful it is.

The further the sound the police siren travels the

more spread out it becomes so the (more / less)

useful it is.

Homework 7

L.O. Why are some things more efficient than others? Part 2

The greater the percentage of the energy that is usefully transformed in a device, the more

efficient the device is, e.g. the comparison between filament lamps and fluorescent tubes.

Complete the following sentences.

When devices transfer e____________, only part of it is usefully transferred to where

it is wanted.

The rest of the e______________ is transferred in some non-useful way or wasted.

Usually the e_____________ is wasted to the surrounding as h____________

Concept of energy conservation:

The energy that is w_________________ does not disappear; it is changed into a

non-useful form.

The non-useful energy in a light bulb is h____________ .

The non-useful energy in a liquidiser is h______________ .

Efficiency of some energy transfers. Energy is measured in units called joules (J).

Device and amount of energy supplied to it
