Reaction Rainbow

Make some tree bubbles, show how solutions make reactions happen, observe a buffer in action, use math to model pH, and do a drop-count titration in this engaging kit. 

This Launch level kit includes a full-color student workbook and a detailed teacher guide, with step-by-step instructions for both hands-on and reading-based activities designed to engage students in acid-base chemistry. Both teacher and student will be able to open the box and start within minutes. This kit is designed to provide over 15 hours of education and entertainment. 

In this kit, the student will engage in these hands-on learning experiences:

• Find out about a fascinating foam that forms on certain trees and recreate it yourself. 
• Investigate how solutions work and learn about different reactions. 
• Think about the properties of acids and bases using buffers and the pH scale. 
• Dig into the mathematical models of pH and acid-base chemistry.
• Explore the process of titration using modeling and hands-on methods.  

Use the Reaction Rainbow kit to answer questions such as:

• What chemical reactions cause soap and other interesting products to form?
• Why do many reactions only happen when dissolved in water?
• How is the pH scale used to describe acids and bases?
• How do buffers keep the pH of solutions stable?
• What is a titration?
• What is the purpose of acid-base chemistry?

Your student is ready for this kit when:

• They have some experience representing chemical reactions using written and mathematical models. 
• They are comfortable measuring different volumes of liquids using standard laboratory containers. 
• They understand the differences between elements, compounds, and mixtures.

The Reaction Rainbow kit is a part of the Science Unlocked Launch series and is recommended for middle and high school students in grades 8-12.
