Colors are all around us and are an important part of our everyday lives. They can be described as the way our eyes perceive different wavelengths of light. The three primary colors are red, blue, and yellow. By combining these primary colors, we can create a wide range of other colors. When light passes through a prism, it separates into a spectrum of colors, commonly known as a rainbow.
Primary Colors
Red: Red is a primary color that is often associated with energy and passion. It is used to express strong emotions and can also symbolize love and warmth.
Blue: Blue is a primary color that is often associated with calmness and tranquility. It is commonly used to represent stability and harmony.
Yellow: Yellow is a primary color that is often associated with happiness and positivity. It is used to convey feelings of joy and optimism.
Secondary Colors
When you mix two primary colors together, you create secondary colors:
Orange: Mixing red and yellow creates orange, which is often associated with enthusiasm and creativity.
Green: Mixing blue and yellow creates green, which is often associated with nature, growth, and freshness.
Purple: Mixing red and blue creates purple, which is often associated with luxury, royalty, and creativity.
Tertiary Colors
When you mix a primary color with a secondary color, you create tertiary colors. These include colors like red-orange, yellow-green, and blue-purple.
Color Wheel
The color wheel is a visual representation of how colors relate to each other. It consists of primary, secondary, and tertiary colors arranged in a circle. The color wheel helps us understand color relationships and how different colors can complement or contrast with each other.

The Living Environment: Students understand that cells are the basic unit of life, that all life as we know it has evolved through genetic transfer and natural selection to create a great diversity of organisms, and that these organisms create interdependent webs through which matter and energy flow. Students understand similarities and differences between humans and other organisms and the interconnections of these interdependent webs.
Cells: Students describe how living things are made up of one or more cells and the ways cells help organisms meet their basic needs.
Give examples of organisms that consist of a single cell and organisms that are made of a collection of cells.
