          TWO TIER DIAGNOSTIC INSTRUMENT (WHITE)

                     ENERGY AND YOUR OWN BODY

INSTRUCTIONS
Your task is to say whether or not the statement is true or false. Which ever your choice
is, please CIRCLE the true or the false.

When you have done this, you should chose one of the reasons that best matches your
reason for saying true or false and CIRCLE the letter for this reason. If none of the
reasons offered is suitable then use the lined space to put your own reason in. Remember
it is important to select a reason. If you do not agree with the reasons given, please
supply your own reason in the space provided.

This test only deals with energy and the human body and what is involved in this. Do
not consider other processes when answering these questions.

       THIS TEST DOES NOT COUNT TOWARDS YOUR ASSESSMENT


1     Blood transports molecules of food around the body so the cells can take these
      molecules in and use them as a source of energy.
                                                                  TRUE/FALSE
     A we absorb the energy produced by the digestion of food and the blood carries
        this energy around our body to where it is needed
     B blood circulating gives us energy
     C blood is unable to support or carry excess energy
     D blood carries oxygen around the body not the energy
     E blood carries the sugars around the body for the cells to absorb which they can
        then use to make energy

     F
2    Respiration can use food molecules such as glucose (and other sugars), fats and
     proteins to produce useable energy (ATP).
                                                                TRUE/FALSE
    A respiration is breathing
    B fats are unable to be used for energy but sugars are
    C energy is released by digestion not respiration
    D we get our energy when we are active (like exercising) not from food
    E respiration burns energy not create it
    F respiration is the process of making all food components into useable energy

    G




3    The heat released from the chemical reactions in our body is a waste product that
     we can use to help regulate our body temperature.
                                                                 TRUE/FALSE
    A chemical reactions contribute to the heat production
    B our body temperature is from the heat we produce when we exercise only
    C the chemical reactions produce heat as a waste product and we convert
       this heat into temperature
    D heat is from the flowing of blood through our veins and arteries not
       the chemical reactions
    E energy is “burned” to give heat for the body
    F the body makes its own heat, it is not from chemical reactions

    G
4   Energy may be stored in the body for later use. Fat (lipids) is one such chemical
    which is used for energy storage.
                                                                    TRUE/FALSE
    A we store fat but we cannot use this fat for energy at some later time
    B energy is changed into fat to be stored
    C excess energy is not changed into fat
    D we store the excess energy in the bonds of the fat
    E respiration does not convert fat into energy
    F there is no left over energy as we use all we take in

    G




5   When we ride a bicycle, some of our energy is transferred to the bicycle.
                                                                  TRUE/FALSE
    A the bike is not living and so cannot use or have energy
    B we use energy up not transfer it to the bike
    C bike makes its own energy
    D use energy to move the pedals but no energy is transferred to the bike
    E our leg movement energy is transferred to the bike and then becomes
       movement energy of the bike
    F we push on the pedals which makes the bike move but there is no energy
       transferred to the bike

    G
6   When we hear a sound, the sound comes from the object into our ears where it is
    converted into electrical energy which the brain can interpret.
                                                                    TRUE/FALSE
    A convert sound energy into electric current and the brain interprets these
        electrical signals
    B sound passes to brain where the sound waves (energy) are interpreted
    C vibrations move the eardrum and then the vibrations pass into the brain
    D sound waves pass through the ear to the brain

    E




7    Different food groups are used as energy sources by the human body and these
     groups have different types of energy and different amounts of energy.
                                                                  TRUE/FALSE
    A all food has the same energy but in different amounts
    B different food groups have different amounts of energy with the same type of
        energy in foods
    C each food has a number of different types of energy in it and each of these are
        in different amounts
    D we carry out different types of activities and so these activities need different
        types of energy to occur

    E
8   We get energy the body can use from a number of sources. Some of these sources
    are food, sleep, air, light, sound and heat
                                                                TRUE/FALSE
    A we only get useable energy from our food
    B we get useable energy from food, air and sleep not the others that are listed
    C these are only some of the ways our body can get useable energy into it
    D we only get useable energy when we are exercising or being active
    E we do not get useable energy from our surroundings
    F we only get useable energy from respiration

    G




9     Respiration is the process in which the energy in food is converted into useable
      energy.
                                                                   TRUE/FALSE
    A respiration is breathing and has little to do with energy
    B respiration is the taking in of energy from food during its passage
        through the gut
    C respiration is the filtering out of bad energy and storing and using good energy
    D digestion is how we get energy not respiration
    E respiration is where the energy in food molecules is converted into useable
        energy
    F
10    Heat is released as a by-product of all chemical reactions that occur in the body.
                                                                    TRUE/FALSE
     A we only get hot when we do exercise or we are active not at other times
     B we only get hot when we sweat
     C we get heat from our surroundings because that is hot
     D heat is a type of energy and when we are active we use up this energy so no
        energy is left
     E get the heat from jumpers and clothes
     F heat is from the friction of the blood flowing around the body
     G




11   Excess heat in the body needs to be removed, this occurs in a number of ways one
     of which is by the evaporation of sweat.
                                                                   TRUE/FALSE
     A heat particles are removed when we sweat
     B heat is removed from the skin by convection currents and
         radiation not evaporation
     C it is the air moving over our skin that makes us cool
     D heat is evaporated away from the skin
     E the process of sweating cools us down not evaporation

     F
12    Respiration occurs within the cells and results in the production of useable
      energy.
                                                                    TRUE/FALSE
     A cells change food into energy
     B respiration is breathing and supplies oxygen not energy
     C it is digestion that produces the energy the body needs from the food we eat
     D respiration is where “food” molecules are broken down to release energy
     E respiration is taking the energy from the digested food

     F




13   When we see an object, light comes from the object into our eyes where it is
     converted into electrical energy which the brain can use.
                                                                   TRUE/FALSE
     A light energy transfers the image to brain
     B the eye captures the image and then the brain receives that image
     C eyes can't receive energy from the surroundings
     D energy goes into the eye, to the retina and then to the brain
         via the optic nerve
     E the eye focuses on the tree and its image is passed to the brain

     F
14   Any excess energy in the food we eat is destroyed.
                                                                   TRUE/FALSE
     A   we don’t absorb the excess energy but excrete it
     B   energy is taken into the body and stored in fat for use later
     C   unused energy is absorbed and then it is destroyed if there is too much of it
     D   we cannot destroy the energy we absorb so we store it in the body as fat so it
         is out of the way
     E   there is no excess energy as we use it all up

     F
