  • Question 1

Bryan is a robot, Leo is a lion.

 

Bryan can carry out some of the same life processes that Leo can.

Which two life processes can both Bryan and Leo carry out?

CORRECT ANSWER
movement
sensitivity
EDDIE SAYS
Animals, plants and micro-organisms (such as bacteria and fungi, but NOT viruses) are classified as living things.
All living things carry out the same seven life processes; they can:
  • produce waste substances (excretion)
  • grow
  • move
  • make their own food - or eat another living thing (nutrition)
  • generate offspring (reproduction)
  • respond to a stimulus such as light or sound (sensitivity)


  • Robot technology is improving all the time. Modern robots can move freely and respond to a stimulus such as a sound or a beam of light. However, robots do not produce waste substance, grow, feed, reproduce or respire.
    • Question 2

    The human heart is a very strong muscle.

    How many chambers is the human heart made up of?

     

    CORRECT ANSWER
    4
    EDDIE SAYS
    The human heart is made up of four chambers.

    These chambers are known as the upper chambers and the lower chambers. We have two upper chambers and two lower chambers. The upper chambers are called atria, the lower chambers are called ventricles.
    • Question 3

    The heart pumps blood around the body. When you exercise, the heart beats more quickly.

     

     

    What substance, which is carried by the blood, is needed in greater amounts during exercise?

    Write one word.

    CORRECT ANSWER
    oxygen
    EDDIE SAYS
    Oxygen is carried in blood by special cells known as red blood cells.

    All our body cells need oxygen to release energy during a process called respiration.

    When we exercise our cells need more energy, especially our muscle cells. Our heart beats faster so that red blood cells can deliver more oxygen to these cells and they can release more energy.
    • Question 4

    Humans have three types of teeth: canines, incisors and molars.

    Match the type of tooth to the correct description.

     

    CORRECT ANSWER

    Column A

    Column B

    canines
    used for ripping and tearing food
    incisors
    help us to bite and chew
    molars
    allow us to grind food
    EDDIE SAYS
    Canine teeth are sometimes called fangs. We usually have four canines in our mouth, two in our upper jaw and two in our lower jaw. Canines are usually the largest teeth in our mouths.

    Incisors are often known as front teeth. Human mouths normally contain eight incisors, although this number often varies in young people depending on what stage of tooth development they are at. The role of the incisor is to cut food sharply.

    Molars are positioned towards the back of our mouths. They are named after the Latin word for millstone mola. We use molars to grind our food. Adults usually have 12 molars in their mouths.
    • Question 5

    Some animals such as crabs have a skeleton on the outside of their bodies.

     

     

     What is this type of skeleton called? 

    CORRECT ANSWER
    an exoskeleton
    EDDIE SAYS
    The exoskeleton is often known as the shell.
    Animals such as crabs, lobsters and snails have an exoskeleton for protection
    Humans have a skeleton inside the body. It is called an endoskeleton.
    • Question 6

    The human life cycle has six stages.

    The six stages of the human life cycle are listed below in alphabetical order. Put them into the correct numerical order.

    CORRECT ANSWER
     123456
    adolescence
    adulthood
    baby
    childhood
    elderly
    foetus
    EDDIE SAYS
    The six stages in the human life cycle are: foetus, baby, childhood, adolescence, adulthood and elderly.
    • Question 7

    Green plants such as the daffodil have leaves, roots and a stem.

     

    Match the part of the daffodil to the job it does.

    CORRECT ANSWER

    Column A

    Column B

    EDDIE SAYS
    The leaves of green plants absorb sunlight for photosynthesis. Photosynthesis is a very important process which green plants use to make their own food.
    Plants also need water for photosynthesis this is soaked up from the soil into the stem by the roots.
    The stem is made up of lots of smaller tubes; some of these tubes mover water up to the leaves, the other tubes move food around the plant.
    • Question 8

    Some animals do not have a backbone.

    What name do we give to animals that do not have a backbone?

    CORRECT ANSWER
    invertebrate
    EDDIE SAYS
    Insects, octopus, snails and worms are all examples of invertebrates.
    Humans, birds, fish and other mammals are all examples of vertebrates.
    96% of all known animals are invertebrates.
    • Question 9

    This picture is an example of a food chain.

    grass   rabbit   fox

     

    What do the arrows represent in a food chain?

    CORRECT ANSWER
    the flow of energy
    EDDIE SAYS
    This is a key phrase, it is really important that you learn it.
    This food chain is quite simple, some food chains are much more complicated. A food chain is a diagram which shows the feeding relationships between animals that live in the same habitat.
    When an animal feeds on a plant or another animal it takes in a small amount of energy from that organism. Scientists say that the energy flows between the different stages of a food chain.
    • Question 10

    Microbes can be very harmful to humans and can cause diseases.

     

     

    What are the three types of microbes that cause diseases called?

    CORRECT ANSWER
    bacteria
    fungi
    viruses
    EDDIE SAYS
    Bacteria, fungi and viruses can cause disease in all living things. Viruses are so small that they can even be harmful to bacteria!

    All three types of microbes are very small and often too small to be seen unless we can use a microscope. This means that they can easily be transferred between different organisms. If the microbe is harmful it will cause a disease.
    • Question 11

    Bread is made using a useful microbe

    What is the name of the microbe that helps bread to rise?

    Write one word.

    CORRECT ANSWER
    yeast
    EDDIE SAYS
    Yeast is added to the bread dough to help the bread rise.
    Yeast is a microbe that feeds on the sugars in bread dough. It produces carbon dioxide gas which helps the bread to rise and also gives the bread its springy texture.
    Yeast organisms are killed by the high temperatures in the oven when the bread is baked.
    • Question 12

    A food chain shows the feeding relationship between plants and animals from the same habitat.

     

    Each plant or animal in a food chain can be labelled as either a consumer, predator or producer.

    Match each key term to its correct description.

    EDDIE SAYS
    All plants are producers. They use light energy from the sun to make (produce) their own food by photosynthesis.

    All animals are consumers, some animals such as greenfly, cows and sheep only eat plants. Other animals such as hawks eat other animals, these animals are called predators.
    • Question 13

    This question is about the life cycle of flowering plants.

    Seeds are made by flowering plants.

     

    Put the stages of the life cycle in the correct order.

    CORRECT ANSWER
     123
    dispersal
    pollination
    fertilisation
    EDDIE SAYS
    Pollen is carried by insects, like bees, and the wind from flower to flower. This process is called pollination.
    When pollen reaches a new flower it moves to the ovary, here it fertilises an egg cell called an ovule.
    Seeds develop and are scattered by the wind, insects and animals. This is called disperal.
    • Question 14

    Robbie notices two different types of flowers growing in the school grounds. Robbie asks Saffron to help him identify the flowers.

      

    Saffron asks Robbie a simple question about the characteristics of the flowers.

    What name do scientists call a set of questions that can separate living things?

    Write one word only.

    CORRECT ANSWER
    key
    EDDIE SAYS
    A key is a set of questions which can be used to identify different living things.
    Questions about the characteristics of the living thing are set and the person who wants to identify it must decide how to answer the question based on what they have observed. The answer is usually yes or no.
    • Question 15

    Some animals like the polar bear have special features that help it to survive.

     

    What name do we call these special features?

    Write one word only.

    CORRECT ANSWER
    adaptations
    EDDIE SAYS
    Animals like the polar bear, who live in very extreme habitats, have special adaptations which help them to survive.
    The polar bear has thick fur and a small nose and ears. These adaptations help the polar bear to keep warm in the freezing cold Arctic.
    • Question 16

    The dandelion is a flowering plant with large green leaves.

    Having large leaves is useful to the dandelion.

    Why it is useful to a dandelion to have large leaves?

    Select two reasons from the list.

    CORRECT ANSWER
    The plant can absorb more carbon dioxide.
    The plant can absorb more light energy.
    EDDIE SAYS
    Having wide leaves helps a plant like the dandelion to carry out photosynthesis.

    The role of the leaves is to absorb light and carbon dioxide. Oxygen is a waste product of photosynthesis and is excreted from the plant through the leaves.
    Water enters plants though the roots from the soil.
    • Question 17

    This question is about habitats and food chains.

    Lots of fish live in this pond. Birds like the heron nest near the pond.

     

     

    What would happen to the fish in the pond if the number of herons in the nest increased?

    CORRECT ANSWER
    They would decrease.
    EDDIE SAYS
    The fish in this pond are eaten by the heron. If the number of heron increases more fish will be eaten.
    Over time the total number of fish in the pond would decrease.
    • Question 18

    Muscles are attached to bones. They help us to move.

    When the muscles in the arm contract and relax it moves up and down.

    Select the correct word to complete this sentence:

    When a muscle contracts, it                 

    CORRECT ANSWER
    shortens
    EDDIE SAYS
    When a muscle contracts it shortens.
    In this example, when the biceps muscle (the top one) contracts it pulls up the lower arm.
    • Question 19

    Alcohol is a drug.

    Caffeine and nicotine, found in coffee and cigarettes, are also drugs.

    These drugs can effect the speed of your reactions.

     

     

    Which statement correctly describes the effect of alcohol on reaction time?

    CORRECT ANSWER
    Alcohol slows down reaction times.
    EDDIE SAYS
    Alcohol is a sedative. It slows down a persons heart rate and their reaction times.
    Many adults drink alcohol socially to help them relax. It is illegal and extremely dangerous to drink alcohol and drive a car. Serious accidents can happen when somebody drinks and drives because they cannot react quickly enough to hazardous situation.

    Caffeine and nicotine are both stimulants.
    Stimulants speed up a persons heart rate and their reaction times.
    • Question 20

    Each part of the flower has a role in the life cycle of a flowering plant.

    Match the each part of the flower to its correct role.

    CORRECT ANSWER

    Column A

    Column B

    petal

    stamen
    the male part of the flower
    stigma
    hairy or sticky to attract pollen
    EDDIE SAYS
    Petals are modified leaves which are often brightly coloured or unusually shaped to attract pollinators such as insects (for example bees), and birds (like the humming bird).
    The sepals are also modified leaves. The are often small and green. The sepals cover the petals before they bloom.
    The stamen is the male reproductive part of the flower. It produces pollen and is made up of two parts, the anther and the stalk.
    The stigma is found in the female part of a flower. It is hairy or sticky to attract pollen.
