Exploring magnets

Sort materials into magnetic and non-magnetic, find the poles of a magnet, and work out what happens when two magnets are brought together.

Before you start

Along a bar magnet, the pull is strongest at some places and weakest at others.

123
  1. 1. North pole
  2. 2. The middle
  3. 3. South pole

Iron filings crowd at the two ends and hardly any stick along the middle. The two ends behave the same way towards filings; what tells them apart is how they behave towards another magnet.

  1. 1.Put the steps for turning an ordinary iron sewing needle into a floating compass back into order.

    • Push the needle through a piece of cork
    • Float the cork in a bowl of water
    • Check the needle now attracts iron filings
    • Stroke the needle from end to end with one pole of a magnet, 30 to 40 times

  2. 2.Match each term to what it means.

    • Non-magnetic material
    • Magnetic material
    • Magnetic compass
    • points along north-south
    • left alone by a magnet
    • drawn towards a magnet

  3. 3.Two magnets are brought close, pole to pole. Sort each pairing by what it does.

    Groups: Attract · Repel

    • Two unlike poles, North facing South
    • Two like poles, South facing South
    • Two unlike poles, South facing North
    • Two like poles, North facing North

  4. 4.Iron filings are scattered under this bar magnet. Tap the part where the fewest of them would stick.

    Write the number of the part.

    123

  5. 5.Which single test tells a magnet apart from a plain iron bar?

    • a) See whether it sticks to a wooden table
    • b) See whether a known magnet pulls it towards itself
    • c) See whether one pole of a known magnet pushes it away
    • d) See whether it is heavier than the known magnet

  6. 6.A magnet hangs from a thread and is free to turn. It settles along a line joining which two directions? Answer with both, joined by a hyphen.

  7. 7.Which of these is good practice for looking after a magnet?

    • a) Tap it with a hammer to straighten it
    • b) Warm it gently before use
    • c) Keep it away from a mobile phone
    • d) Store it loose at the bottom of a bag

  8. 8.A magnet is brought near each of these materials. Sort them by whether it draws them towards itself.

    Groups: Magnetic · Non-magnetic

    • Cardboard
    • Glass

Motion and reference points

Use a reference point to decide whether something is moving, and tell linear, circular and oscillatory motion apart.

Before you start

Each thing in this park shows one of the three kinds of motion.

123
  1. 1. Swing — oscillatory
  2. 2. Merry-go-round — circular
  3. 3. Slide — linear

The swing and the merry-go-round both come back to where they started, again and again. That is what makes them periodic.

  1. 1.A metal strip is clamped at one end. You press the free end and release it, and it moves up and down. Which kind of motion is that?

    • a) Circular motion
    • b) It does not move
    • c) Oscillatory motion
    • d) Linear motion

  2. 2.A distance is stated with respect to a fixed object or point. What are those two words for that fixed point?

  3. 3.When is an object said to be in motion?

    • a) When it is making a noise
    • b) When it is not touching the ground
    • c) When its position changes with respect to the reference point over time
    • d) When it is heavier than the reference point

  4. 4.Which pair of motions does the chapter call periodic?

    • a) Circular and oscillatory
    • b) Linear and oscillatory
    • c) Linear on its own
    • d) Linear and circular

    • b) Some of them had been to the garden and some had not
    • c) The garden moves during the day
    • d) They were using different units of length

  6. 6.An eraser hangs from a thread. You pull it to one side and let go. What does it do?

    • a) Travels off in a straight line
    • b) Stays exactly where you released it
    • c) Moves to and fro, in the same way as a swing

    • a) Circular motion
    • b) It does not move
    • c) Oscillatory motion
    • d) Linear motion

  8. 8.Sort each of these by the kind of motion it shows.

    Groups: Linear motion · Circular motion · Oscillatory motion

    • A pushed box sliding along the floor
    • A march-past at a parade
    • A merry-go-round turning

Materials around us

Group materials by whether you can see through them, whether they dissolve in water, and whether they shine — and say what makes something matter.

Before you start

How much of the shape behind each pane gets through.

123
  1. 1. Window glass
  2. 2. Butter paper
  3. 3. Cardboard

The same shape sits behind each of the three panes: sharp through the transparent one, blurred through the translucent one, and hidden by the opaque one. Translucent is its own group, not a weak kind of transparent.

  1. 1.Anything that occupies space and has mass is given one general name. What is that name?

  2. 2.Any substance used to make an object is called a ___. Which word fills the gap?

  3. 3.Fish live in water and need oxygen. What does the chapter say makes that possible?

    • Chalk powder
    • Sawdust
    • Sand

  8. 8.Match each word to what it describes.

    • Transparent
    • Translucent
    • Opaque
    • you cannot see through it
    • you can see through it clearly
    • you can see through it, but not clearly

States of water and the water cycle

Tell the three states of water apart by how they behave, name the changes between them, and follow water round the water cycle.

Before you start

The stages water passes through on its way from the ocean and back again.

1234
  1. 1. Evaporation
  2. 2. Condensation
  3. 3. Rain
  4. 4. The ocean

Water rises from the ocean as vapor, cools high up into cloud droplets, falls back as rain and flows to the ocean again. There is no first stage — water has been going round this loop far longer than anyone has been watching it.

  1. 1.A block of ice is heated, and the heating is kept up. Put the three states in the order the water passes through them.

    • Water vapor
    • Water
    • Ice

  2. 2.How does the chapter say a cloud is formed?

    • a) Water is lifted from the sea as whole drops by the wind
    • b) Smoke from the ground gathers and turns white
    • c) Rising air cools, and its water vapor turns into droplets around dust particles
    • d) Cold air sinks and squeezes water out of the ground

  3. 3.The water cycle turns round and round with no true beginning, so start it from evaporation and put the stages in order from there.

    • Flowing back to the ocean
    • Condensation
    • Evaporation
    • Rain

  4. 4.Cloud droplets are light enough to float. What has to happen before they fall as rain?

    • a) The wind pushes the droplets downwards
    • b) The droplets freeze solid and drop as ice
    • c) Many droplets join into drops heavy enough to fall
    • d) The cloud runs out of dust particles to sit on

  5. 5.An ice cube left on a table turns into water. What is this change called?

    • a) Freezing
    • b) Melting
    • c) Evaporation
    • d) Condensation

  6. 6.Dew forms on plants overnight, and drops gather under the lid of a boiling pan. What is the name of the change turning water vapor back into liquid?

  7. 7.Water moves round between the Earth's surface and the atmosphere and comes back again. This circulation has a two-word name. What is it?

  8. 8.Tap the stage of this water cycle where water leaves the ocean and enters the air as vapor.

    Write the number of the part.

Temperature and its measurement

Say why touch cannot judge hotness, read a thermometer correctly, and convert a Celsius temperature to the Kelvin scale.

Before you start

Slide along this laboratory thermometer's scale. Its range runs from one end to the other, and each small step is ten degrees.

-101030507090110

A clinical thermometer covers nothing like this stretch, which is why it cannot be used on boiling water or on ice.

  1. 1.A thermometer that reads a person's temperature without touching them has a name in the chapter. Which is it?

    • a) A laboratory thermometer
    • b) A clinical thermometer
    • c) A non-contact, or infrared, thermometer
    • d) A mercury thermometer

  2. 2.Can a clinical thermometer be used to measure the temperature of boiling water?

    • a) Yes, but the reading has to be doubled
    • b) No, because boiling water has no temperature
    • c) No — boiling water lies outside its range
    • d) Yes, if it is held in for long enough

  3. 3.Why must a laboratory thermometer be read while its bulb is still in the water?

    • a) The liquid column starts to fall the moment it is taken out
    • b) The glass cracks if it is lifted out too quickly
    • c) The scale becomes unreadable out of water
    • d) The reading takes an hour to settle

  4. 4.One hand comes out of warm water and the other out of ice-cold water. Both go into the same bowl of tap water, and they report different things. What does the chapter conclude?

    • a) One of the hands is faulty
    • b) The tap water changed temperature in between
    • c) Touch is not a reliable way to decide how hot something is
    • d) Warm water makes whatever follows feel cold

  5. 5.A temperature of 37.0 °C on the Celsius scale is the same temperature as which reading on the Fahrenheit scale?

    • a) 100 °F
    • b) 98.6 °F
    • c) 273.15 °F
    • d) 37.0 °F

  6. 6.What is the name of the device that measures temperature?

  7. 7.A room is at 25 °C. What is that on the Kelvin scale? Answer with a number.

  8. 8.Put the steps for measuring the temperature of warm water with a laboratory thermometer back into order.

    • Dip the thermometer so the bulb is immersed, clear of the bottom and sides
    • Read it with your eye level with the top of the column, while it is still immersed
    • Wait until the liquid column stops rising
    • Hold it vertically, without tilting it

123
  1. 1. Shoot
  2. 2. Seed
  3. 3. Root

The shoot grows upwards into the air and the root downwards into the soil. Turn the seed upside down before planting it and the root still finds its way down.
