pH
Comment on this resource
This lab activity is designed to teach students how to test for pH and understand its relationship to them and their environment. They will learn what pH is, draw and label a pH scale, measure the pH of various items, and explain why it's important to understand pH, for example, the danger presented by substances having very high or low pH.

This lesson will help students gain experience in asking questions and conducting inquiry by exploring the separation of colors in water and other solvents; and to communicate and share findings of student investigations. The lesson uses a technique called paper chromatography, which is demonstrated using water, ink, and a coffee filter. Scientists use chromatography frequently to separate and identify ...

In this lesson, students will view salt under varied magnifications and begin to construct the understanding that materials may be composed of parts that are too small to be seen without magnification. They will observe salt with the naked eye, and then under a hand lens, microscope, and the electron microscope (the electron image is via the Internet). In order to complete this lesson, it is important ... Full description.

Comment on this resource
The colligative properties of solutions consist of freezing point depression, boiling point elevation, vapor pressure lowering, and osmotic pressure. These properties ideally depend on changes in the entropy of the solution on dissolving the solute, which is determined by the number of the solute molecules or ions but does not depend on their structure. This resource presents the derivations of the ... Full description.
