Light and Colour
Levels 3 and 4
NZC Achievement Objectives
PW3/4-1: (Physical Inquiry and Physics Concepts) Explore, describe, and represent patterns and trends for everyday examples of physical phenomena, such as movement, forces, electricity and magnetism, light, sound, waves, and heat. For example, identify and describe the effect of forces (contact and non-contact) on the motion of objects; identify and describe everyday examples of sources of energy, forms of energy, and energy transformations.
Te Mātauranga o Aotearoa
Force and Motion: Investigate and use scientific models of force and motion, and some applications, e.g. friction, levers and pulleys.
Waves and Particles: Investigate and use scientific models to explain the physical phenomena of light, sound and heat.
Electricity and Magnetism: Investigate and use simple scientific models of electrical circuits and magnets.
Te Tōpana me te Nekenga: Ka tūhura, ka whakamahi i te tauira pūtaiao hei whakaatu i te tōpana me te nekenga, me ētahi whakamahinga, pēnei i te waku, te kauwhiti me te tauru.
Te Ngaru me te Ngotangota: Ka tūhura, ka whakamahi i te tauira pūtaiao hei whakaatu i te aho, te oro me te pōkākā.
Te Hiko me te Autō: Ka tūhura, ka whakamahi i ngā tauira pūtaiao māmā mō ngā ara iahiko me ngā autō.

Integration ideas are from the Ministry of Education
Students can explore how mirrors reflect light. They can suggest directions in which the light is likely to travel.
Students can explore how shadows change in size and intensity. They can make links between shadows and angles of light from the Sun, a torch, or an overhead projector.
Students can explore various lenses and observe the different ways they refract light.
Students can explore and describe ways in which white light can be split into a spectrum and discuss the idea that white light is made up of many colours of light.
Students can investigate how mirrors reflect light. They can explain their observations using ideas about light that scientists have proposed.
Students can describe how the intensity and length of a shadow can change. They can understand relationships and trends in observations.
Students can research how scanners work and attempt to explain how the machine can “read” information in a barcode.
Students can compare their intuitive ideas with scientific concepts about lenses and the refraction of light.
Students can explore and describe ways in which white light can be split into a spectrum. They can make links between their observations and scientific ideas.
Mathematics and Statistics (Number and Algebra): Sketch a graph to show the height of a shadow from a nearby building at different times of the day.
