Resources for colour lessons - Material: safe acrylic that is healthy and non-toxic for classroom use. - Function: translucent sheets let students look through them to see how environments change under different colours; used as colour filter tools. Optical instruments - Function: enables students to explore colours independently by mixing sheets of different colours. - Benefit: supports hands-on discovery of colour interactions and serves as a practical teaching tool. Teaching accessories - Material: safe acrylic colour filter plates. - Use: can be combined to achieve different effects, including cool effects, colour correction, and colour-transparency applications. Colour filter set - Construction: solid acrylic plates to protect hands and equipment during scientific exploration. - Benefit: durable, safe hardware for hands-on colour work. 2-3 use scenarios - In-class colour lesson: overlay multiple colour filters to demonstrate additive and subtractive colour concepts and lighting changes. - Independent exploration: students mix various colour sheets to observe transparency, colour mixing, and pattern effects. - Demonstrations and labs: instructors use the set to illustrate colour correction and protective handling of equipment during experiments.
