- Educator Quick Start Guide: These content area specific guides provide samples of guided questions and student prompts designed to incorporate each Collisions HE content area into your chemistry lectures and tutorial classes for both pre-instructional and post-instructional use.
- Formative Assessments: These documents are fillable PDFs for student practice that directly align to each Collisions content area. They can be used to analyze student understanding or to help reinforce a specific concept.
- Extension Activities: These are analysis activities that can be used to extend learning by prompting students to draw connections to additional chemistry concepts covered in Introduction to Chemistry and General Chemistry courses. In these activities, students ‘collect data’ in the Collisions HE Sandbox, and analyze the results to draw conclusions about a concept.
