Colors Collide or Combine
Source Institutions
Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.
Traveling Through Different Liquids
Source Institutions
Learners observe and record what happens when they manipulate bottles containing a liquid (water or corn syrup) and one or more objects (screw, nail, paper clip).
Exploring How Liquids Behave
Source Institutions
Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.
The Liquid Rainbow
Source Institutions
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
Exploring Liquids
Source Institutions
Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
Peripheral Vision
Source Institutions
In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.
Chemistry Is Colorful
Source Institutions
In "Chemistry is Colorful" learners explore different materials through paper chromatography.
Nature of Dye
Source Institutions
"Nature of Dye" allows participants to create their own dyes and art while exploring how chemicals interact and how these interactions can have real-world applications.
Changing Colors
Source Institutions
In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.
Candy Chromatography
Source Institutions
Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.
Light is Made of Colors
Source Institutions
Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.
Canned Heat
Source Institutions
In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.
Chromatography
Source Institutions
In this activity (page 3 of the PDF), learners will observe a physical change.
Using Color to See How Liquids Combine
Source Institutions
Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.
See the Colors in Leaves
Source Institutions
Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.
