It is always helpful to have a lab that can be adapted to meet the needs of students. The "Magnesium Lab" is one of these experiments.
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?
The September 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: reticular chemistry; laboratory research experience for students; historical perspective; chemistry and the environment; laboratories using color to understand chemistry; electrochemistry laboratories; DIY instrumentation; organic semiconductors; orbitals; computer-based learning and computational chemistry; from the archives: paper chromatography.
It’s the beginning of a brand new school year, and a brand new opportunity to capture students’ interest in chemistry and the joy of lab-based sciences! In thousands of chemistry classrooms across the country, teachers will be planning labs, demos, and ways to have students be engaged and excited about learning.
Erica Jacobsen shares highlights from the June 2018 issue of the Journal of Chemical Education.
How do you demonstrate how a buffer system works? I did some brainstorming, devised a plan and it went well. This post is a description of what I did.
This activity is designed to determine the concentration of Vitamin C (ascorbic acid) in a produce protector (in this case, Ball® Fruit Fresh) by an iodometric titration method.
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
Recently, while attending the High School Teacher Day at the ACS National meeting in New Orleans, we were given Wack-A-Pack™ valentine balloons and encouraged to play with them. I am a huge fan of finding chemistry in the real world and using it as an integral part of my instruction; and as we were experimenting, I was reminded of a rather fun activity I had done on Valentine’s Day with my AP students.
Titrating this year for me has an added complication. The complication is that half of the science department has to be completely packed up and out of our rooms, including chemicals and equipment, before school ends. Half of the department is going to be completely remodeled (my half of course). Teaching must still go on in the middle of the madness.
