Using the average current, the students determine the number of electrons liberated during the reaction. Knowing the mass of copper lost by the anode and the number of electrons liberated, the students are able to determine the number of copper atoms removed from the anode, which they use to determine the mass of a single copper atom.

Jean-Jacques Rochat spent a few days skiing near his chalet in Ovronnaz, Switzerland. Even though he is no longer a science teacher (now a principal), he could not resist collecting data.
Ute Kaden took her Vernier LabPro and sensors to the North Pole! At a latitude of 89° 58.5′ she measured salinity, temperature, barometric pressure, and acceleration due to gravity.
Anna Mika, 7th grade teacher at Cumberland Middle School in Cumberland, WI, worked with her students to design a research project that NASA could implement on a high-altitude research balloon. The students’ project was to measure the protection from UV radiation provided by various clothing materials.
In collaboration with researchers from the University of Kentucky, Heidi Anderson, AP Biology teacher at Paul Laurence Dunbar High School in Lexington, KY, has developed an inquiry-based investigation of heart rate. What makes her approach unique is she studies crayfish.
Spectral analysis of four common food dyes is a great way to introduce spectral analysis, as it helps students understand the relationship between the color of the solution and the ideal wavelength they should use to measure variations in absorption. Students are often surprised to see that yellow dye peaks in the blue wavelengths and red dye peaks in green wavelengths.
David Drummer, physics teacher at Kutztown Area High School in Kutztown, PA uses a K’NEX® rollercoaster and Vernier 25-g Accelerometer to investigate impulse and challenges his students to design crash protection using paper and masking tape to reduce the maximum force needed to stop the car.
In the spirit of Thanksgiving, we’re bringing back the Turkey Activities! Two years ago, we had several activities themed around Thanksgiving. Due to their popularity, we’ve brought them back.
Thomas Haff, physics teacher at Issaquah High School in Issaquah, Washington, often gives his students inquiry based problems to solve. This year, he asked his students to determine the amount of force a tennis racket will exert on a tennis ball.
Brian Lamore is a physics teacher at the Chinquapin School in Highlands, Texas. While preparing to evacuate his school for Hurricane Rita, Brian recognized a unique opportunity to collect some data. Brian set up a LabPro with a Barometer to collect the changes in atmospheric pressure as the powerful storm went by. Fortunately, Brian made it through the storm safely and captured some great data.

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.
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.
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.
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.
Parker Moreland has been volunteering at an intermediate school in New Milford, CT, where he has come up with a clever modification of the “What Causes the Seasons” lab in our Earth Science with Computers book. Continue reading about “What Causes the Seasons?”
In March 2005, Olathe North HS (Olathe, KS) students Kevin Skov and Greg May, along with teacher Steve Obenhaus, took a trip to the southern reaches of Texas to explore Laguna Madre’s hypersaline characteristics. Laguna Madre, a large body of shallow water separating Padre Island from the South Texas mainland, is one of only a few hypersaline lagoons in the world.
