Students will be able to:

Recognize that light can be reflected and that shiny surfaces, such as polished metals and mirrors, are good reflectors.

Recognize that light can be bent (refracted) and that such objects as aquaria, prisms and lenses can be used to show that light beams can be bent.

Recognize that light can be broken into colours and that different colours of light can be combined to form a new colour.

Student Notes

1 Light around us

Begin by finding out what students already know about light.  Create a Popplet, Google doc or simple bulletin board where students can add what they know about light, how it travels and how we can manipulate it.


Student Instructions

What do you know about Light?  How do you think light moves?

2 Explore with Light

Use the digital tools either as a whole class, small groups or individually to explore the concepts of reflection and refraction.

*The Bobo app is especially good for many of the concepts related to light and shadows - you can use this app as a discovery station all throughout the unit

Use an App like Explain Everything and have students explain their understanding of the concepts of light reflection and refraction.

Student Instructions

Explore with the apps Bobo Explores Light and Meet Science: Light and sound to learn about how light is reflected or refracted.  

Explain what you have learned using the app Explain Everything.

3 Color Wheel

Have students explore with flashlights and prisms in real life - or if you don't have access use the Bobo Explores light app and a projector to share with students the colors of the spectrum (ROGBIV) then using Art Studio App or a paint program of your choice, have students create their own color wheel.

They can use the digital color wheel for future art projects - determining warm and cool colors
