Product Details

Finally an easy way to combine the primary colors of light! Many people have seen white light dispersed into a spectrum after it has passed through a prism, but few have observed different colors of light combined to make white light. In this teacher-led demonstration, white light from an overhead projector passes through three holes in a plastic sheet. Each hole in the plastic is covered with a transparent sheet of colored acetate—one red, one green, and one blue. This allows red, green, and blue light to be projected as three separate circles onto a white wall or screen. With the help of convex lenses, the three projected colors are refracted and overlap with one another on the screen to create white light. Kit comes complete with three convex lenses, plastic sheet with precut holes, and three colored transparencies. Detailed teacher notes and student worksheet are also provided. One overhead projector is needed for this demonstration.

Performance Expectations

MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-ETS1-1: Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
MS-ETS1-2: Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
MS-ETS1-3: Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-ETS1-2: Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
HS-ETS1-3: Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics, as well as possible social, cultural, and environmental impacts.
