A Great Introduction to Stoichiometry

This lab is one of my favorite activities to do in my classes and I look forward to it every year. The lab is simple, requires limited supplies, students love it (i.e. high engagement level), and I have found it to really set students up for stoichiometry.

Video-Enhanced Automatically-Graded Web-Based Pre-Lab Tutorials

In our freshman Chemistry laboratory course at Nicholls State University, tutorials (with embedded quizzes) are used as pre-lab assignments. The text and graphical information provide a sufficient basis to answer all the questions, but YouTube videos are embedded for students who may need additional help. The tutorials could be easily adapted for flipped instruction in high school and college lecture courses.

NGSS-ify Alka-Seltzer Rockets

Given a guiding question, students determined what they wanted to test, did the experiment and got their CER boards ready for review. Instead of a regular argumentation session, we had a glow and grow session, where students had to provide positive and negative feedback for each board.

Capping Off a Unique Redesign of the Laboratory Curriculum

A few years ago, the faculty in our department at Slippery Rock University of Pennsylvania decided to switch to an atoms first approach to the General Chemistry course. We took advantage of this change to systematically redesign the first semester of the laboratory curriculum to be a true “laboratory course” that focuses on laboratory practices, techniques, and equipment rather than on chemical theory.

Take Home Labs

Several teachers I know have had circumstances present themselves in which they may not always be able to provide lab experiences in a traditional lab setting. They still want to provide students with rigorous problem solving situations that require students to use the scientific method. Could rigorous take home labs possibly be the answer?
