This post focuses on the virtual chemistry laboratory activities created for students pursuing a bachelor of science degree in Primary Teacher Education at the University of Bologna.
The lab activity shared here is a simple experiment where students use stoichiometric principles to experimentally determine the amount of sodium bicarbonate in an Alka-Seltzer tablet. Novice students tend to find stoichiometric calculations difficult, so practicing the calculations on a pre-lab assignment boosts their confidence and ultimately leads to more successful labs. The Asynchronous Video Pre-Lab Assignment shared here demonstrates the procedure and the calculations required in the experiment.
Teaching during COVID was challenging; however, a few positive results surprisingly emerged. For one, Josh Kenney filmed a small library of chemistry lab videos for use in virtual chemistry labs after his school switched to remote learning. At first, he wasn't sure if he would continue to use those videos when his district returned to in-person instruction until he discovered that they would make excellent pre-lab assignments.
During the last few semesters, a small survey has been deployed at Bradley University where students were to describe and classify items of litter that they found. The purposes of the surveys were to get students thinking about some of the chemical implications of solid waste and give the students some experience with a citizen science project. The most recent iteration of the survey, and some of its results, are described.
This post addresses concerns about the quality of the future of chemistry education in an online environment.
EdPuzzle is a content delivery tool that can increase student engagement and metacognition. Here, we will explore how to use this application to help your students learn in a remote or hybrid setting.
In this virtual activity, a video introduces stoichiometry and guides students to think conceptually using a simple baking analogy. Afterward, stoichiometry calculations connect to the analogy, that are then reinforced with a simple experiment. Finally, students explore a PhET simulation to deepen their knowledge.
The Types of Chemical Reactions Lab is a favorite for many teachers and students. Chemistry comes to life as students record observations. This virtual version by no means replaces the students physically conducting the reactions themselves but during these times this activity can be used to supplement the teaching of chemical reactions.
Ben Meacham is editing videos using software he had not used until just a few weeks ago. He shares what he has learned about creating these videos for his students that are now virtual. Students can watch the steps of the procedure and collect data from the video so they can complete a post-lab assignment.
In this activity, students learn about solubility and concentration. They watch videos that explain the dissolving process, how to calculate the molarity, supersaturation and how to make rock candy. They also use a PhET simulation to explore factors that affect the concentration of a solution.
