Improved CO₂ Gas Sensor

Our CO₂ Gas Sensor has been redesigned with several great improvements, including an expanded range to accommodate human respiration, lower power requirements allowing it to be used with a Go!Link, and a new sleek form factor. The new CO₂ Gas Sensor has two ranges for optimum resolution in each range. The low setting has a range of 0 to 10,000 ppm CO₂. This provides good resolution for small changes in CO₂ levels, such as the respiration of peas, photosynthesis of plants, or respiration of insects. The high setting has a range of 0 to 100,000 ppm, making it perfect for measuring the concentration of CO₂ gas in human respiration. The new CO₂ Gas Sensor can be used with a LabQuest, LabPro, Go!Link, or CBL™2.

BioChambers

Designing and conducting experiments using our CO₂ and O₂ Gas Sensors is easier than ever with our new BioChambers.

These versatile chambers come in two sizes: 250 mL and 2 L. Both can accommodate our CO₂ and O₂ Gas Sensors for studying the gas composition during photosynthesis or respiration. Use the 250 for small samples, such as peas, crickets, or leaves. Use the 2000 for plants or larger samples.

CO₂ and O₂ Sensors shown in the pictures above are not included.

Pulley Bracket for Vernier Dynamics System

We now have a simple bracket for attaching a pulley to the end of the track from a Vernier Dynamics System. The Pulley Bracket fastens to the underside of a Vernier Track and accepts the Vernier Ultra Pulley (order code SPA, $23) or other popular low-friction pulleys.

Use the bracket to create a half-Atwood machine. Monitor the pulley rotation with a Photogate if you want, or use a Motion Detector to follow the cart.

Fathom 2.1 Software Supports Vernier Sensors

If you teach mathematics or statistics, you may be familiar with Fathom Dynamic Data™ Software. Fathom allows you and your students to analyze, manipulate and display data in many revealing ways. In the past, Fathom users imported sensor data from web sites or other external sources; now you can collect data from most Vernier sensors directly into Fathom using a LabPro, Go!Link, Go!Temp, or Go!Motion. A complement to Logger Pro, Fathom is a perfect way to add extended statistical analysis tools to your classes. For more information, see www.vernier.com/fathom

Den of Inquiry Volume 2

The Den of Inquiry books are data-driven inquiry experiments that encourage students to ask questions, make predictions, and create and apply models. Each book has about 15 activities for either Fathom Dynamic Data Software or Logger Pro. The first volume has experiments that do not require sensors. This new, second volume offers a selection of sensor-based experiments in introductory physics. If you're looking for inquiry-based activities for your physics or mathematics classes, take a look at these books. Both include CDs with electronic versions of the activities, experiment files, and other information. Visit www.vernier.com/cmat/den2.html for further information, including a list of activities.

Ciencias con lo Mejor de Vernier
(Science with the Best from Vernier)

We took 42 of our best experiments from five subject areas and translated them into Spanish. Contents of the lab book include:

• Introducción a la Adquisición de Datos - 1 experiment
• Biología (Biology/Life Science) - 9 experiments
• Química (Chemistry) - 9 experiments
• Ciencias de la Tierra (Earth Science) - 9 experiments
• Física (Physics) - 9 experiments
• Calidad del Agua (Water Quality) - 5 tests

The book includes complete student experiments with materials list, step-by-step instructions, data tables, and questions. It has a Teacher Information section for each experiment, with complete directions for setting up experiments, helpful hints, and sample graphs and data. A CD is included in the back of the book with word-processing files of the student pages, so that you can easily edit them to your specifications.
