Analyze how light interacts with different objects and materials to create phenomena such as shadows, reflection, refraction, and dispersion.
Indicators for this outcome

Pose questions about the interaction of light with different materials (e.g., How are shadows formed? How can we change the direction of light? What colours are in light?).


Investigate how light interacts with various objects to determine whether the objects cast shadows, allow light to pass, and/or reflect light.


Classify materials and objects as opaque, transparent, or translucent based on personal observations.


Design and carry out a fair test of the reflective properties of surfaces of different shapes and textures (e.g., mirrors, flat foil, crumpled foil, white paper, coloured paper, and spoons).


Develop simple conclusions about the reflective properties of surfaces of different shapes and textures based on observation and experimentation.


Demonstrate and describe how transparent media of different composition and shape (e.g., prisms, plastic blocks, glasses of water, and lenses) are used to change the direction of light.


Investigate how light interacts with optical devices such as kaleidoscopes, reading glasses, microscopes, periscopes, telescopes, and magnifying glasses.


Demonstrate the dispersion of white light into various colours using a prism, and draw simple conclusions about the composition of white light.


Identify characteristics and effects of radiation that are slightly below (i.e., infrared radiation) and slightly above (i.e., ultraviolet light) the frequencies of visible light.


Experiment with mixing colours of light to create colours that meet a student-specified function (e.g., mood for a dance or dramatic production).

Light: Stop Faking It! Finally Understanding Science So You Can Teach It
This resource from the Stop Faking It! Series helps teachers deepen their understanding of science concepts related to optics. The author addresses teachers' concerns about content and helps to fill in any gaps of understanding that may exist. Emphasis is on "getting" the science rather than on memorizing facts and formulas. This book explores ray, wave and particle models of light, reflection and refraction, optical instruments, polarization of light and interference and diffraction. A chapt...

Pearson Saskatchewan Science 4. Student Edition
Pearson Saskatchewan Science 4 is custom published for Saskatchewan and developed by a team of Saskatchewan teachers. Each unit starts with a list of "Big Ideas" that set the focus for the unit. A Big Idea then provides the title for each section in the unit. Throughout the unit, opportunities are provided for students to work together, communicate ideas, perform experiments and carry out library and Internet research. Key vocabulary is bolded throughout the unit and an explanation of each te...
