Vernier brings its cutting-edge technology to your biotech lab! The new Blue Digital Bioimaging System allows you to illuminate your gels, capture the image digitally on your computer, and analyze the data using Logger Pro software. The Blue Digital Bioimaging System includes the BlueView Transilluminator™, Imaging Hood, ProScope digital USB camera with 1-10X lens, and a ProScope Stand.
The Garmin eTrex Vista Cx is the first GPS receiver to communicate with Logger Pro through USB (Logger Pro version 3.4.6 or newer, Windows only). The eTrex Vista Cx is loaded with popular features, including a barometric altimeter, electronic compass, sunlight-readable color screen and advanced GPS routing capabilities—all in a waterproof design. In addition, it comes with a blank 64 MB microSD card for storage of optional map detail.
A new addition to our line of sensors is an infrared thermometer. The sensor works by measuring the infrared radiation emitted by objects. For most objects, you simply point the sensor at the object and read its temperature. Our Infrared Thermometer features automatic backlighting, simple ON/OFF operation, and laser sighting.
Students at Susquehanna Township High School in Harrisburg, Pennsylvania, participated in a program where the students studied the life cycle of the blowfly and its relationship to the decomposition of a deer.
Judy Day, with the Science House, a NC State University K-12 science outreach program, has developed an activity investigating a plant’s response to gravity. Judy uses a ProScope USB digital microscope to record changes over time in a plant that has been placed on its side.
Airplane noise in the Long Beach area is a frequent topic of debate. This motivated Riley, Tim, and Mario to measure the noise level at points along the flight path of Long Beach runway 30 as their science project. Based on their research, they believed that planes landing would create a higher level of sound intensity compared to planes taking off.
We investigated whether the color of olive oil is due to chlorophyll. We tested two grades: extra virgin (purported to have the maximum amount of chlorophyll of all grades of olive oil since it is derived from the first pressing of the olives) and light (alleged to contain no chlorophyll).
