Color Wheel Poster
This large colorful poster will provide a useful reference for classroom discussions of color mixing. The chart provides a side-by side comparison of additive (light) color mixing (on the left-hand side) with subtractive (pigment) color mixing (on the right hand side), so the relationship can be easily seen. The top section of the chart shows the color wheels and primary colors for both additive and subtractive colors. The middle section of the chart demonstrates the science of adding different primary colors of light and pigment, and shows how the color wheel can be used to predict the resultant colors. The bottom section of the chart describes complementary colors of light and pigment, again, in reference to the color wheel.
Light Matters Poster
This unique color poster describes the interaction of light with matter using a picture of the natural phenomenon, a diagram showing the essential physics, and a written description. The poster in divided into three sections. The first section describes the scattering of light by small particles, which is responsible for the color of the sky as well as sunsets. The second section presents examples of the interaction of light with bulk matter, where the light can be reflected, transmitted, or absorbed. Here, the phenomena of specular and diffuse reflection, the dispersion of light by a prism and the formation of a rainbow, and the color of water and leaves are lucidly discussed. The third section describes the emission of light, using a computer monitor and the color of hot objects as examples. The poster includes references for additional information and a section on details and clarifications.
Seasons Poster
The top half of this poster shows pictorially how the orbit and tilt of Earth give rise to the seasons. The bottom half of the poster provides data and graphs that demonstrate that the seasons are due to both the number of daylight hours and the angle of the sun with respect to Earth’s surface.
