Labquest2 Probes in Fermentation Lab

The Core Biology courses have been studying the production of carbon dioxide by yeast during fermentation. In this class, the students used the Labquest2 and carbon dioxide probes to gather data on the amount of carbon dioxide produced (ppm) over time. They are comparing the results for four different sugars (maltose, glucose, sucrose, and lactose). The Labquest2 enabled to student to capture and share the data as it was being collected via their mobile devices.

These devices were purchased thanks to a very generous grant from the Bronxville School Foundation.

Fermentation Lab Set-up consists of the Labquest2 Tablet which collects data from a carbon dioxide probe (measures ppm) in a flask with 5 ml of yeast suspension and 5ml of a sugar solution.

Brendan's cell phone is receiving the data in real time from the Labquest2 tablet.

Briana sets the parameters for data collection on the Labquest2 while Peyton checks her technique.

Mary Clare and Peyton enter the information used to identify the particular data of this run of the experiment before they print out the graph and data table produced.

Ryan gives the whole process a "thumbs up" as his lab partners Chris, Yanni and Ralph concur.

Vivian semms quite relaxed knowing she has properly configured her group's Labquest2 to collect their data.

Environmental Science Class Discuss "Cradle to Cradle Design"

The Environmental Science class completed their research into global citizenry and "Cradle to Cradle Design" with a Socratic Seminar in which class members discussed what they had learned and what they felt they could do moving forward about intelligent design and its relationship to "hybrid" recycling of materials within the Biological Cycle and the Technological Cycle.

James, Henry, and Jill are listening intently to the discussion as Jocy jots down a thought that has just occurred to her.

Alex, Willow and Samantha are busy preparing for the seminar.

Claire, Emily and Meredith are listening carefully to the points being presented.

Liam makes a cogent point about how the "plastic" gyre in the oceans are impinging on the quality of life.

Paul makes his point as Kyle and Luke ponder what Paul is saying.

APES Students Transect Mark and Recapture Activity

Transect Marking is a process rather clearly defined in the following entry from Wkipedia:

     "A transect is a path along which one records and counts occurrences of the phenomena of study (e.g. plants).  It requires an observer to move along a fixed path and to count occurrences along the path and, at the same time, obtain the distance of the object from the path. This results in an estimate of the area covered and an estimate of the way in which detectability increases from probability 0 (far from the path) towards 1 (near the path). Using the raw count and this probability function, one can arrive at an estimate of the actual density of objects. The estimation of the abundance of populations (such as terrestrial mammal species) can be achieved using a number of different types of transect methods, such as strip transects, line transects, belt transects, point transects^[1] and curved line transects.^[2] "

In Dr. DiTulio's class the students had gathered plant population data from transects around the school campus. These pictures show them compiling their data onto maps of the areas they examined.

Probeware Technology Incorporated into High School Laboratories

     Thanks to a generous grant from the Bronxville Foundation, the high school science labs will be introducing new probeware technology into the classroom. Each lab table will now be equipped with a Labquest2 Probeware Tablet. The table interfaces with data collection probes, stores lab protocols for students to follow during the gathering of data, collects data in both tabular/graphical formats, enables statistical analysis of the data collected, allows students to take and save notes, and most importantly being WiFi equipped, the tablets can transmit all the data as it is collected in real time to each student's mobile device (IPads, IPods, Laptops, Android devices) when equipped with the proper APP. Completed experimental data maybe collected using a USB thumb drive, it can also be sent to each student's e-mail address for analysis on their home computer.

     The following is a promotional video describing the system from Vernier:



     The grant has enabled the department to equip each science discipline's lab with probes that can carryout basic investigations (for use in Core Bio, Core Chem, Core Earth Science and Core Physics courses) and advanced inquiry investigations that align with AP and IB curricula (for use in the Honors Biology II, Honors Chem II, Honors Earth Science II, Honors Physics II, AP Biology, AP Chemistry, AP Environmental Science, and AP Physics courses). This system will allow our teachers to adapt included labs/customize included labs/create new labs /and upload the lab protocols to the tablets using a Lab Creator and Lab Organizer Programs/Websites provided by Vernier.

     The system is completely portable, so students will be able to take the tablets and probes into the field to collect data for analysis. The following is a list of probes that will be available as classroom sets (one for each lab table, tablet). One set of probes will be assigned to each of the six high school classrooms.

Biology Probes - Temperature Probe, Hand Grip Heart Rate Monitor, Gas Pressure Sensor, CO2 Sensor

Inquiry Biology Probes - Temperature Probe, Hand-Grip Heart Rate Monitor, Gas Pressure Sensor, CO2 Sensor, Spectrovis Plus Sensor

Chem Probes - Temperature Probe, pH Sensor, Gas Pressure Sensor, Voltage Probe

Inquiry Chem Probes - Temperature Probe, pH Sensor, Gas Pressure Sensor

Earth Science Probes - Temperature Probe, Light Sensor, pH Sensor, UVB Sensor

Physics Probes - Motion Detectors, Dual-Range Force Detectors, Microphone, Differential Voltage      Probe, Photogates, Rotary Motion Sensors.

Bronxville Student to Represent County in National Brain Bee Contest

   
      Tepi Ennis snared first place in the local Brain Bee Contest held at the Burke Rehabilitation Center in White Plains. The Brain Bee is a trivia quiz competition which tests the participants knowledge of the nervous system.

     Tepi will represent the county in March in the US Finals to be held in Baltimore.
