We are pleased to announce the 2008 Vernier/NSTA Technology Award Winners. The winners are awarded for their innovative use of data-collection technology using a computer, graphing calculator, or other handheld in the science classroom.
Vernier consultant, Walter Rohr, came across an article published in the February 1989 Journal of Chem Ed that described a method of resolving mixtures with overlapping spectra without determining molar absorptivities or complicated mathematics. The method developed by Blanco called Multi-Wavelength Linear Regression Analysis, or MLRA, allows the composition of a binary mixture with overlapping spectra to be resolved with only three measurements—the absorbance of a standard solution for each component, and the unknown mixture itself.
Brillion Middle School teachers Ryan Peterson and Matt Van Thiel have their 8th grade Earth Science students do a fun and engaging activity on topographic mapping. The activity is based on the Earth Science with Vernier activity “Ocean Floor Mapping.” Using plastic utility tarps, they create a simulated lake in their classroom.
“With media attention on species extinction and global warming, environmental science has an intrinsic interest for students. The best way to study the environment (the air, water, and soil) and the interactions among biological organisms in the environment, is by performing good experiments using the inquiry model of learning. In today’s classrooms, experiments can be improved though the use of quality sensors and measuring equipment. This book helps students do both.”
The Vernier LabQuest just received a wonderful review in MultiMedia & Internet@Schools, an educational publication. The review gave the LabQuest a 5-Star rating (out of 5) with the following grades:
East of Use: A
Product Support: A+
“Students will enjoy using LabQuest…. I was impressed by the rugged construction. This is definitely a tool that will last, which makes it an excellent buy—especially with today’s tight funding…. I have no doubt that LabQuest is going to get plenty of use in my classroom. I would highly recommend it for every classroom that is serious about engaging students in meaningful scientific investigations.”
