Serc: Investigating Compositions: Using Chromatography to Explain Color Patterns

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....

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...

What is a color spectrum? Simple, it's comprised of the colors of the rainbow. Have the classs read a passage about the color spectrum and then complete two short answer activities. 

The concluding skills unit offers learning opportunities and reviews in preparation for assessments. Scholars participate in lessons that examine spelling patterns, prefixes, suffixes, pronouns, and adjectives, draft a letter, and listen...

Colors are more than just a pretty effect. Learners explore what color change means in terms of chemical properties and reactions. They create a pH solution using cabbage leaves and observe the changes when acids and bases are added. 

Don't let your brain play tricks on you! Learners test brain reaction rates while it is receiving multiple stimuli. They time each other reading a set of color words written in different colors and again when they are written in black....

Watch celery change from green to purple in a video that demonstrates how celery absorbs food coloring to change the color of the leaves. The resource has viewers thinking about the science behind types of water and photosynthesis.

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....

Using their own classification methods students will identify the types of trees found around their school and neighborhoods. Students will then present their classification methods to the class. Later students will use dichotomous tree...
