The Lungs and Spirometry Parameters B-41

Posted on June 17, 2013 How much air do we breathe? The normal amount of air that we breathe in and out when we are at rest is called tidal volume (TV). An average tidal volume is around half a liter. We can also inhale a very large amount of air and then exhale all the air we can, the volume of that exhaled air is called our vital capacity (VC) (typically 3.1-4.8 liters). We cannot exhale all the air from our lungs. There is approximately 1.2 liters of air that remains in our respiratory tracts; it is called the residual volume (RV). The total amount of air that we can hold (the vital capacity plus the residual volume) is the total lung capacity (TLC). Its volume is approximately 4.2-6 liters.In this activity we will measure the tidal volume (TV) and the vital capacity (VC) using a spirometer logger sensor. Download experiment

Soil Moisture B-20

Posted on July 3, 2013 Soil is composed of different particles; most of them originate from the degradation of rocks (mineral particles). Others come from plant or animal residues (organic particles). Soil can also contain living materials (bugs, roots etc.).The particles have small spaces between them called pores. When the pores are filled mostly with air, the soil is “dry”. When they are filled with water then the soil is “moist”.The NeuLog soil moisture sensor can be used to know when to irrigate becuase the plant does not have enough water. The sensor is called a tensiometer, which is used to measure the energy status (or potential) of soil water. The measurement is directly related to the ability of plants to extract water from the soil.In this activity we will monitor the moisture of soil in a pot containing a plant. Download experiment

Static Electricity P-44

Posted on July 17, 2013 Static electricity is the result of an imbalance between negative and positive charges in an object. Charges build up on the object’s surface until they find a way to discharge. By rubbing certain materials against each other, negative charges can transfer from one object to the other. For example, when rubbing a balloon against a woolen fabric or your hair, the balloon becomes negatively charged and the hair/fabric becomes positively charged. In this experiment we will rub together different objects and measure their charge with a charge logger sensor. A Faraday cage will be used to protect the objects from external electric fields.

Simple Pendulum P-46

Posted on August 1, 2013 A simple pendulum is a hypothetical apparatus consisting of a point mass hanged on a thread. The thread’s mass is negligible and it is free to vibrate without friction. The motion of the hanged mass is harmonic, it swings back and forth at a constant amplitude. This is true as long as the angle from the original position is small. The amplitude of a real life pendulum swing declines over time because it is subjected to friction. A pendulum’s period is the time it takes to the hanged mass to swing back and forth. The period of a simple pendulum depends on the length of the thread and the gravitational acceleration (g); not on the mass of the pendulum. A pendulum with a long thread has a greater period than one with a shorter thread. The period and the frequency (1/period) are independent of the initial angular position (for small swings). In this experiment, we will measure the angular position over time of a swinging hanged mass connected to a rotary motion sensor through a thread. Different lengths and different masses will be examined, and the expected period will be compared with the measured period. Download experiment

What’s New?

NeuLog presents, Sense: A robotic and computer programming system which allows users to explore, problem solve, and advance their computer programming abilities from just starting in visual block programming, to Python and C languages. The sense platform can be expanded by over 45 different NeuLog sensors so that you can create solutions and codes the world has never thought of for any problem you try to over come.

 

Neulog’s ability to email data at the end of an experiment is built using Google’s mail system. In February of 2017 Google made a security update that that disabled this ability. Do not worry, we created a free update that reinstates the capability. Please take a moment to download and install the newest NeuLog software here.

Our WiFi modules (WIFI-201 and WIFI-202) can now work both with NeuLog sensors and Panda multi-sensor. In order to work with the sensors type wifi201.com in the URL bar. In order to work with the Panda multi-sensor, type panda201.com.  The new NeuLog Panda multi-sensor includes Temperature, Light, Barometric pressure, Altitude, Sound, Relative Humidity, Dew-Point, Magnetic Field and G-Acceleration sensors. Panda is used for environmental data collection and other experiments in Natural Science, Biology, Physics and Chemistry. It is specially designed for primary school level.   Three new sensors are now available: mA Current,  Resistance and Geiger counter logger sensors. Scholastic Tech Tools Stopped by at ISTE, look what they have to say:  Click here to see the review A new version of the NeuLog application has been released for PCs, Mac computers ,Tablets and Smartphones! The application allows you to operate NeuLog logger sensor in a very simple and intuitive way. Including these great new features: Automatic sensor recognition, new design, user friendly interface, graph markers and more! With our  WiFi Communication module  you can now use NeuLog logger sensors with any device which uses the Wi-Fi technology, such as iPads and Tablets with Android, PC computers with Windows / Linux or Macintosh with OS (the last firware update) The NeuLog Application Programming Interface (API) allows users to control NeuLog sensors with their own software. check out our new blog!
