Coloring Fabrics With Dyes from Plant Materials K-12 Experiments & Background Information

Knowledge of acids and bases doesn't need to be a secret. Learners use red cabbage to create an indicator solution, then test how adding lemon juice (acid) and detergent (base) changes the color of the solution. They then use the concept...

Here's an activity that will change how one sees color. Pupils try out an experiment on chromatography where they place a drop of food coloring on a coffee filter, add several drops of water, and watch the colors spread and separate....

Students explore the light spectrum. The teacher uses holographic diffraction grafting film on an overhead to demonstrate the true nature of color. After observing a vivid rainbow, students recognize that white light is composed of all...

The classic carnation color-change activity for demonstrating water transport up a plant stem is played out in this video. Add the clip to a PowerPoint presentation or show it when teaching plant structure to young botanists. If you have...

Young scholars explore light and color, including how colors are mixed to produce new colors, how light is filtered, and how light is reflected off of surfaces. They read materials provided, complete worksheets, and complete hands-on...

Photocopy single-color images onto acetate transparencies and either demonstrate or have your class experience the combination of colors to produce images. Children will learn that cyan, magenta, yellow, and black combine to make all of...

Fourth graders explore how colors react in water (chromatography) and other solvents. They observe, investigate, measure, record data and communicate their results in the form of graphs/charts and narration presented to the class....

Everyone loves the beautiful colors of fall, but where they come from and how they change color is a mystery. In this project, you will uncover the hidden colors of fall by separating plant pigments with paper chromatography.

In this experiment, students will explore the properties of color using chromatography then observe and compare color patterns to differentiate compositions of various colors.

Students explore the components of light as a combination of several colors. The focus of the lesson reveals that objects are viewed in a certain color because that color is reflected off of the object.
