Overview

In this CLAW (Chemistry Laboratory Alternative Work) At-Home experiment, students will perform an experiment using household chemicals and materials. It was designed as a substitute for in-person laboratories, usually performed at the college level, during the COVID-19 pandemic.  However, it may also be used as an experiment that students can carry out in the lab or for student projects.

Instructional Objectives

The objective of this at-home chemistry experiment is to determine the conditions and properties favoring solubility. Mixing of commercially available household items are carried out to qualitatively evaluate and understand solubility behavior.

Benefits

  • This hands-on home experiment is an engaging way to manipulate and measure chemical compounds outside an official laboratory set-up;
  • Experimental data recorded by the students can be analyzed to write a complete lab report.

Challenges

  • It may be difficult to estimate the time needed for students to complete this activity at home.
  • Gathering of chemicals and material usually carried out by a technician must be done by each student.

Tips

The list of chemicals and material necessary for the experiment should be given to students as soon as possible to make sure they have the time to purchase and gather the needed items.
