Building Science Concepts: Shadows
Several basic science concepts are needed to understand shadows. The New Zealand Ministry of Education’s Building Science Concepts (BSC) series presents sets of interlinking concepts that...
Activity
Investigating shadows using transparent, translucent and opaque materials
In this set of investigations, students explore objects made from materials that are transparent, translucent and opaque and the effect this has on their shadows. The...

Alternative conceptions about light and shadows
Children naturally and instinctively develop their own ideas about how things work. These self-developed concepts make sense to the individual but may be scientifically inaccurate. It...
Activity
Investigating shadows and the position of the Sun
In this activity, students use scientific models and exploration to observe the position of the Sun and its physical effect on light and shadows. The activities...

Physics made simple – waves
In this recorded professional learning session, Greta Dromgool and Ted Cizadlo will build your confidence to teach about the Physical World. The New Zealand Curriculum achievement...
Activity
Make a hologram-like projector
In this activity, students use a sheet of acetate to make a transparent, four-sided pyramid. The pyramid’s sides act as four mirrors, situated at 45° angles...
Activity
Investigating waves and energy
In this investigation, students work with slinkies to explore longitudinal and transverse waves. They have the opportunity to establish the relationship between frequency and wavelength and...
Activity
What is refraction?
In this activity, students are introduced to an analogy through a role-play that helps them visualise the refraction of light. The analogy explains why light bends...
Activity
Make an electric motor
Three historic discoveries were instrumental in the development of electric motors – the invention of the battery by Alessandro Volta in 1800, the generation of a...
