New Vernier Tools Demonstrate Key Engineering Concepts
Software & Technology just launched the Vernier
& Materials Tester (VSMT) to help students in both high school
and college to understand key engineering concepts. The VSMT is a device
help students who are designing, building and testing structures like
understand how important load and stress levels are.
The VSMT is a device about 20 inches tall that has a
sensor that can measure up to 1,000 N (units of force) and a
sensor that can measure with a precision of 0.1 mm resolution. With
these two tools,
students can record maximum breaking loads as well as the
force and stress. There is also video analysis software in conjunction
sensors that can help them visualize the exact moment when their
bend and break.
"When I taught, bridge competitions were one of my
activities," said Vernier co-founder and former physics teacher David
it was challenging to test all of the bridges and accurately apply force
measured way. Now, students can use the Tester with sensors and
devices to assess bridges and use the data to refine their designs."
The VSMT is accompanied by a tackle kit that has all
necessary aluminum plates, chains, rods and accessories to build bridges
structures of varying sizes and shapes.
The suggested price of the Vernier Structures &
Tester is $999.
For younger students — those in the fourth through
grades — Vernier has released a new lab book, "Investigating
Wind Energy," that
will guide them through inquiry-based investigations to learn
design methods. The lab book has 10 investigations and one culminating
where students can design, test and refine a wind turbine blade set that
converts wind energy to electrical energy.
The investigations and project are intended to help
explore quantitative current, potential difference, power and energy.
"These types of inquiry-based investigations engage
in scientific discovery at an earlier age and provide the foundation
as they progress through STEM instruction," Vernier said.
suggested price of "Investigating
Wind Energy" is $25.
