Rainbow in a Tube (Ages 6-18)

One of our most popular science workshops - everyone loves making these rainbows in a tube!

This amazing workshop shows how beautiful science can be.  Students learn about density so they can stack-up all the colors of the rainbow and prevent them from mixing.

 

The Rainbow in a Tube workshop is an engaging and interactive learning experience designed to introduce students to the concept of density through a hands-on experiment. The experiment involves creating a tube with six different colors of water, each with a different density (created by adding salt), and observing how they settle in the tube. Students will learn how to calculate density from mass and volume.

Objectives

• To introduce the concept of density to students and explain its importance in science and everyday life.
• To provide students with a fun and engaging way to learn about scientific concepts through a hands-on experiment.
• To teach students how to calculate density from mass and volume.
• To encourage students to ask questions and think critically about the experiment and the scientific principles behind it.
• To promote teamwork and collaboration among the students as they work together to create the tube and make observations about the density of the water.
• To inspire students to pursue further learning and exploration in the field of science.

Outcomes

Upon completion of the science workshop, students will have achieved the following outcomes:

• Developed a basic understanding of density and how it relates to mass and volume.
• Acquired the ability to calculate density from mass and volume.
• Demonstrated an understanding of how salt can be used to change the density of water.
• Improved teamwork and collaboration skills through working together to create the density tube.
• Enhanced critical thinking skills as they ask questions and make observations about the experiment.
• Developed an appreciation for the fun and interactive nature of science, and a desire to further explore the subject.
