The Chemistry of Bathtub Tints
Jack Randall, one of our resident chemistry gurus, just can’t leave things alone. Jack has taken a cute bath product called Bathtub Tints (made by Crayola(R)) and turned it into an opportunity to conduct chemistry experiments. As Jack puts it, “It may not be bath time, but it’s time to do some investigations with these little bundles of fun.” You might like to try some of these activities with your students.
The Volume of a Person
Eric Koser and his 9th grade physical science students at Mankato West High School in Mankato, Minnesota had spent lots of time doing experiments with overflow cans exploring mass, volume and density. They also spent some time considering what the density of a person might be and decided to measure it. Fortunately, one of Eric’s colleagues is married to a welder and she had her husband build a human-sized overflow can. Eric used Force Plates to measure the density of a person.
Friends of Trees
On October 28th, 23 Vernier Software & Technology employees volunteered their time to plant trees in the wetlands near our office. This was a joint project with the non-profit group, The Friends of Trees. We planted 200 trees and spent a lot of effort to make sure the trees survive. The trees that were planted in the same spot five years ago were all destroyed by nutria from the nearby creek. We used tubes, stakes, and wire to keep the nutria away.
It was a physically exhausting job, but we had a good time and it will be very interesting to watch the trees grow over the next few years.
Happy Halloween from Vernier
We hope that everyone will have a safe and happy Halloween. In our offices, strange creatures roamed about and brought sweet treats along. Here are a few of the funny and creative costumes this year.
Our programmers demonstrated how to count in binary.
Our front office department showed us their nerdy side.
Not to be outclassed, our marketing department snatched the best group costumes award with their Willy Wonka and the Chocolate Factory theme.
Join the Celebration!
Vernier’s 25th anniversary is fast approaching and we want you to share the celebration. We know that many of you have great stories about how data-collection technology changed your teaching and enhanced your students’ learning. We want to celebrate your use of technology in science and showcase your classroom. If we publish your story, you will receive 25th Anniversary T-shirt, and $100 Vernier Gift Certificate. We will be publishing up to 25 stories.
Experimenting with a Thermocouple
Thermocouples are one of the most common temperature sensors. They can be used to measure temperatures between -200 and 1400 degrees Celsius. If you have never had the opportunity to do an experiment using a Vernier Thermocouple, here are three activities to try: Flame Mapping, Bending Glass, and Heating Curve for Ethanol. This might be just what you need to heat things up this fall.
Flying with Vernier
Brian Czapor and some of his fellow students from the University of Akron participated in the SAE (Society of Automotive Engineers) Aero Design® Competition. In order to improve their design, they used the Vernier LabPro and our 3-Axis Accelerometer to give them flight data.
English Language Learners Use Go!Temp for Language Growth
It is the goal of English Language Learners (ELL) teachers to make every lesson a language lesson. Using lessons with hands-on activities not only gets the children physically active in a lesson, but also provides opportunities for developing language. This has been the experience of Charlotte Park Elementary School first grade ELL teacher Dr. Juanita M. “Marti” Moore. Read more »
