    Nigel Latta puts his body on the line to test the kind of weather we usually try to avoid. Explore the science – and the ethical issues – behind his recreations of torrential rain, hurricane force winds and hypothermia.

    Listen to your mum and put on a hat.

    Science ideas and concepts in Episode 3: Weather

    In between the drama and humour, Nigel introduces a number of important science concepts. This episode explores:

    • rainfall, whether torrential or gentle, is driven by the water cycle
    • insulators keep things warm by stopping the flow of energy through them
    • the empirical nature of science: scientific explanations are based on observation and are testable
    • ethical decision making in scientific and technological research.

    Nature of science

    Nigel does not have time to wait for a hurricane, so he tests his ideas using models. It is easier and safer to place a human in a controlled model like a wind tunnel rather than in a real hurricane.

    Resources on the Science Learning Hub provide an in-depth – and safer – means to further explore these concepts.

    Rainfall and the water cycle

    Rainfall, whether a gentle drizzle or Nigel’s torrential flow, is driven by the water cycle. Rising water vapour cools and condenses into droplets, which become suspended on dust and accumulate in clouds – as demonstrated by Nigel in his cloud tank. When the droplets get too heavy, they fall to Earth as precipitation.

    Rainfall and the water cycle

    The resources we have on H₂O on the go, the water cycle – introduction follows water’s journey through the hydrological cycle. Water, in all its forms, is continually exchanged between the Earth’s atmosphere, biosphere and geosphere.

    Sometimes rainfall becomes a bit intense. These resources explain the causes and some of the terminology associated with heavy rainfall events.

    Activity ideas

    Nigel uses models to help explain extreme weather events. The following activities use models to aid students with their understanding of aspects of weather and the water cycle. They are suitable for mid and upper primary levels.

    Insulation and warmth

    “My mum always says, if you’re going out, wear a hat.” That’s sound advice from Nigel’s mum. Keeping warm involves stopping the transfer of heat from one object to another. This can be done by insulating the object. This works because insulators stop the flow of energy through them. Nigel found that covering his head with an insulator (a hat) reduced the flow of energy from his head.

    Humans insulate themselves by wrapping up in layers of clothing. We insulate our homes with materials like fibreglass and plastic foam. Animals fluff up their feathers or fur to trap air to reduce energy loss. Divers rely on a layer of water trapped close to their skin by a wetsuit and warmed by their bodies.

    Antarctica is one of the coldest places on Earth. Scientists working there know a lot about insulation. Learn more about how they keep themselves warm in this extreme environment.

    Activity idea

    Humans can always put on an extra layer of clothing if they get cold. Animals and plants have special adaptations to help them survive. This activity uses reading skills to locate and integrate information about adaptations. Students then design their own unique animal or plant capable of living in Antarctic conditions. This is suitable for mid primary level and above.

    The empirical nature of science

    Nigel recreates different types of extreme weather to demonstrate the effects on his body. Although his approach is often light-hearted, Nigel’s capers provide ideal opportunities to explore the New Zealand Curriculum’s Investigating in science strand. For example, Nigel uses a variety of approaches to investigate models, conduct fair tests and find evidence.

    Early in the episode, Nigel comments on the importance of consistency. He also says, “I will be the first to admit that this is not a completely scientific test.”

    Each weather event includes the collection of data from a testable situation. While watching this episode, it is possible to identify examples of good experimental design (for example, use of a control in the hypothermia test) and ‘not completely scientific’ design (for example, use of consistent wind speeds to test the ability to stand in hurricane-force winds).

    The development of scientific knowledge also has a creative side. This episode has examples in which imagination and creativity were used to find ways to model the extreme weather events and aid in data collection (for example, using nine leafblowers to model a category 2 hurricane).

    The Nature of Science is the overarching and unifying strand in the New Zealand science curriculum. Hub resources help unpack the four substrands, one of which is Investigating in science.

    Ethical decision-making in scientific research

    Nigel jokes that his TV series could easily be named Trying to Kill Nigel Latta. Both the wind tunnel and hypothermia tests were stopped because of safety concerns. This raises some intriguing ethical questions:

    • Should Nigel put himself in danger to educate and entertain audiences?
    • Even though Nigel says, “Don’t try this at home,” should viewers be shown risky events they can recreate?

    Teaching students how to make ethical decisions is mandated by the New Zealand Curriculum. Ethical issues raised by advances in science and technology present important contexts for teaching. The Hub has extensive resources to guide and support ethics teaching in the classroom.
