Dear AACT,

Hopefully the instructions for the challenge include explicit direction to make the health and safety considerations part of the proposed designed method. ... Jim

PS. Please send a copy of the full challenge instructions so that I may confirm the presence of this important aspect.

PS. "There's more to lab safety than just labs!"

American Association of Chemistry Teachers
AACT provides its members with a robust collection of classroom resources created by teachers for teachers. Each month AACT will highlight a new resource to help you create engaging and informative lessons that you can implement into your curriculum.
The August High School Classroom Resource of the Month is the inquiry-based lab, Chemistry Composition Challenge. Students will have the opportunity to design a method to solve three chemistry problems involving moles, molecules, and density.
Objectives
By the end of this lab, students should be able to:
  • Identify an unknown substance using density.
  • Complete error analysis on an investigation.
  • Understand the relationships between mass, moles, and molecules and related calculations.
Teacher Preparation: 5 minutes
Lesson: 60-90 minutes
This resource aligns with the Next Generation Science Standards (NGSS)
HS-ETS1-2: Design a solution to a complex real-world problem by breaking it down into small, more manageable problems that can be solved through engineering.
