The Human Body

The Amazing Machine lecture engages children by way of lively participation to help them to appreciate how the experiences of their own body relate to the functions of Respiration, Digestion, the Senses, Memory, Illusion, and Muscles Bones & Movement. For Key Stage 2 (KS2) there is an optional special story to help children identify and commit the seven process of life to memory.

The greater interaction that comes from working with smaller sized groups turns this into an exciting workshop session where, amongst other things, children get to join in feeling a giant pulse, help an apple through a giant intestine and go on journey through the circulatory system.

Although very effective with all age groups, this workshop is particularly popular with ‘Early Years’ groups and, as with the vast majority of SciTech workshops, the pace and content is determined solely by the children themselves under the guidance of the lecturer and will vary from group to group. Given sufficient time, the workshop plans to cover the following topics:

  • Respiration
    • The purpose of the lungs
    • How the lungs work
    • Blood & air supply
    • The mechanics of breathing
  • Blood Function
    • Oxygen & Carbon Dioxide transport
    • Nutrient & Chemical Waste transport
    • Infection control
    • Temperature control
  • Circlulatory System
    • Location of the Heart and Lungs
    • The Heart
    • Two Simultaneous pumps
      • Left – supplies the whole body including the head
      • Right – supplies the lungs only
    • Heart Rate & Capacity
      • What is a pulse?
    • Blood moves around body in a closed circuit
    • Blood Vessels
      • Arteries
      • Veins
      • Capillaries
  • Digestion
    • The body needs the nutrients extracted from the food we eat.
    • The Mouth
      • Teeth
        • Incisors
        • Canines
        • Molars & Pre-molars
      • The Tongue
        • Saliva
          • Lubricant for swallowing
          • Digestive function
          • Wetting the tongue
          • Antiseptic
      • The stomach
        • Some nutrient absorption
        • Breaks down the food mechanically and with acid
      • The intestines
        • Function & location
        • The intestines are long to give the digestive process more time
        • What is left behind (faeces) was never required by the body
      • The Liver
        • Regulates the nutrient supply
        • Nutrients can be accessed very quickly from the liver (slowly from food)
        • Kidneys
        • Location
        • Blood filtering system
        • The use of blood resident nutrients creates new waste chemicals
      • Bladder function & location
        • How food moves through the body – Peristalsis
  • The Senses
    • The 5 senses + time
    • Perception
      • Memory
      • Illusion
  • Muscles, Bones and Movement
    • The Skeleton
      • Support
      • Protection
      • Blood production
      • Movement
      • Muscles can only pull (not push)
      • Muscles work in pairs or groups
  • Life Processes (optional KS2 only)
    • There are 7 tests that ALL have to be passed to be a living creature
      • Reproduction
      • Respiration
      • Excretion
      • Response to Stimuli
      • Nutrition
      • Growth
      • Movement
    • The KS2 module uses a linked list story to facilitate committing the 7 life processes to memory.
