Vernier Video Analysis™, a new member of our family of apps, is available. Right now, you can get a free trial through June and take advantage of our special introductory pricing. Many physics instructors have long used the video analysis feature in Logger Pro® as a tool to help students learn key topics such as projectile motion, uniform acceleration, center of mass motion, and topics outside of mechanics.
We recently used our Go Direct® Respiration Belt to investigate the biomechanics of running. This sensor has a built-in pedometer that can measure steps and step rate. With this in mind, we modified our “Barefoot Running” experiment, which is available as a free download.
The temperature and the pH at which enzymes function are extremely important. Most organisms have a preferred temperature range in which they survive, and their enzymes function best within that temperature range. If the environment of the enzyme is too hot, acidic, or basic, the enzyme may irreversibly denature, or unravel, until it no longer has the shape to function properly. The enzyme catalase is found in nearly all living organisms; students can use our O2 gas sensors to quickly investigate the effect of temperature, pH, or other factors on catalase.
Middle school students have a lot of energy, but their muscles can actually fatigue faster than they realise. This idea of muscle fatigue is explored in the experiment “Get a Grip” found in our new middle school e-book, Exploring Life Science. In this experiment, students squeeze a bulb connected to Go Direct® Gas Pressure Sensor.
Add another layer to your investigation of rotational motion by integrating this activity designed for advanced high school and college physics. The Centripetal Force Apparatus Moment of Inertia Accessory Kit is an excellent tool to expand the range of experiments and investigations with the Centripetal Force Apparatus or the Go Direct® Centripetal Force Apparatus.
Do you teach force and motion? Equipped with a load cell to measure force and both an accelerometer and gyroscope to measure motion, our Go Direct® Force and Acceleration is perfect for hands-on science activities. Drag a sneaker across the floor to study friction, or tie Go Direct Force and Acceleration to a string and swing it around your head to investigate circular motion
Balance is a complex task that involves input from multiple sensory sources. Visual input, proprioceptors from the limbs and joints, and input from the inner ears are all involved in balance. In “Balance,” students use the accelerometers in the Go Direct®Force and Acceleration Sensor to detect movement while a subject balances on two legs and then on one leg, with eyes open and then closed.
Complete a conductometric titration using Go Direct® Conductivity Probe. Data is automatically graphed in Graphical Analysis 4, and students can use the analysis tools to determine the equivalence point.
Our chemistry team recently posted a free experiment to our website, “Absorbance and Fluorescence Characterization of Vitamin B2.” In the experiment, students explore the properties of riboflavin using a spectrometer and our free, recently updated Vernier Spectral Analysis®. Spectral Analysis v4.8, released in February 2019, now includes fluorescence support. You still get the user-friendly interface that walks students through the data-collection process to easily set up a full spectrum experiment, Beer’s Law experiment, kinetics experiment, or emissions; but now you will have these options for fluorescence data as well.
During a recent snowfall, Richard Born, an associate professor emeritus from Northern Illinois University, captured a slo-mo video (240 frames/s) of falling snowflakes using his iPhone® X. The camera was approximately a foot in front of a wooden fence to serve as a background for the falling snow.
