Immobilization of Lactase Enzyme on Alginate Beads - A Quick Test

Andrea Amato | Mon, 01/07/2019 - 18:18

I came across an interesting Journal of Chemical Education article that explains how it is possible to crosslink sodium alginate, leading to the formation of calcium alginate beads. Calcium alginate beads are hydrogels and one of their uses is to immobilize enzymes in their structure. I thought it would be cool to immobilize some lactase enzyme onto calcium alginate beads and investigate its ability to hydrolyze lactose. 

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?

Summer of POGIL: Reflections and Teaching Tips

Stephanie O'Brien | Tue, 07/17/2018 - 09:35

The summer is an ideal time for reflection, a time to process and grow as an educator. This summer I was fortunate enough to attend the POGIL® National Meeting at Washington University in Saint Louis as well as assist as one of the facilitators at the Northeast Regional Meeting at Manhattan College. While there are numerous ways to spend your summer vacation, I wanted to share some reasons why POGIL® draws me in time and again.

The Chemistry of Outer Space

A variety of activities performed at a science camp that relate to the chemistry of the solar system are reported. These activities could prove useful in the chemistry curriculum or in planning for National Chemistry Week in 2018, the theme of which is Chemistry is Out of This World!
