Overview:

This demonstration involves properties of carbon dioxide and hydrogen. A video is included in addition to the written instructions. It touches on a number of areas of chemistry: density of gases, solubility of gases, sublimation and combustion. Each of these areas could be explored in more detail, depending on the level of the group.

Chemistry - Explaining Solutions
Unrestricted Use
CC BY
Rating
0.0 stars
Overview:

This is a culminating activity to be used after completion of a Solutions unit, or later in the curriculum as review or evidence of concept retention. Students will create and label molecular level drawings of aqueous solutions, differentiating between dilute and concentrated solutions, electrolyte and nonelectrolyte solutions, and to illustrate how an ionic solid dissolves.  For each, students will explain in detail what is happening using Livescribe Echo pens.

Rating
0.0 stars
Overview:

In this "quick lab", students evaporate a saturated salt solution to produce a variety of salt crystals (table salt, epsom salt, alum) over a night or weekend. The following day, they draw, describe, and compare their crystals with those of their classmates.

Solutions: Solubility and Miscibility
Read the Fine Print
Rating
0.0 stars
Overview:

In this lab, students will investigate the solubility and miscibility of several substances using water as the solvent. Students will submit a lab report that includes predictions, data table, and analysis explaining whether materials were soluble or insoluble in molecular terms and/or drawing molecular diagrams of the substances.

Solutions and Solubility Curves
Read the Fine Print
Rating
0.0 stars
Overview:

In this lesson, students will learn about the components that make up liquid solutions as well as environmental factors that can change their characteristics. Students will also examine solubility curve graphs to explore how environmental factors affect the amount of solubility present in solutions. The teacher will begin instruction with a demonstration of supersaturation using a sodium acetate solution. Additional instructional resources include a solubility presentation, suitable for lecture, and handouts providing practice in reading and interpreting solubility curve graphs.

Why Does Water Dissolve Salt?
Read the Fine Print
Rating
0.0 stars
Overview:

Students make a 2-D model of a salt crystal and use water molecule cut-outs to show how water dissolves salt. After seeing an animation of water dissolving salt, students will compare how well water and alcohol dissolve salt. They will relate their observations to the structure of salt, water, and alcohol on the molecular level.
