Learning Outcomes / Ngā Whāinga Ako

1. What is Radiation?
   • I can name the main source of radiation and describe how it transfers energy
   • I can recall the order and use of each type of electromagnetic radiation
   • I can name the seven colours of the visible spectrum and describe how to produce a spectrum by dispersion
2. Why are some types of radiation dangerous?
   • I can name some types of ionizing radiation
   • I can explain why UV radiation is linked to skin cancer and why rates are relatively higher in NZ than in other countries
   • I can describe strategies to reduce the risk of developing melanoma
   • I can explain a technological use of UV light
3. How can we see objects?
   • I can state the difference between a luminous and non-luminous object
   • I can annotate a diagram to show how rays of light enter our eyes
   • I can describe a regular reflection and give some examples of its use
   • I can label the main structures of the eye and explain how the structure enables us to see
4. How can light play tricks on us?
   • I can explain why refraction is
   • I have made observations on the behaviour of light rays when they move from air to glass
   • I can explain why a coin will disappear in a cup when we pour water into it
5. Applications
   • I can apply knowledge about radiation to new situations
