Experiment setup for identifying planetary transits with a Vernier Light Sensor Maya Falck, Scott Godsen, and Rebeca Waysek, teachers at The Spence School in New York City, New York, were inspired by an activity developed through NASA’s Kepler ...

Our new Human Physiology Experiments: Volume 1 lab book contains a complete set of laboratory instructions for our Go Direct human physiology sensors. This book also includes several new and exciting activities, such as the “Balance” experi...

During the 17th century, there were two competing models to describe the nature of light. Isaac Newton believed that light was composed of particles, whereas Christopher Huygens viewed light as a series of waves. Because Newton observed straight-lin...

It can be challenging to find a safe wet lab activity that demonstrates the periodicity of common periodic properties. In this International Year of the Periodic Table, try incorporating a conductivity probe, such as our versatile Go Direct Conducti...

Spectroscopy can be used to determine the concentration of a substance in an aqueous solution. Spectroscopy can also be used to measure the progress of a chemical reaction. The rate law of a chemical reaction describes, in equation form, the effec...

Cell respiration refers to the process of converting the chemical energy of organic molecules into a form immediately usable by organisms. Glucose may be oxidized completely if sufficient oxygen is available by the following equation: All organism...

Cell respiration refers to the process of converting the chemical energy of organic molecules into a form immediately usable by organisms. Glucose may be oxidized completely if sufficient oxygen is available by the following equation: C6H12O6 + 6O2(...

Scientists working in forensic labs are often asked to perform DNA profiling or "fingerprinting" to analyze evidence in law enforcement, mass disasters, and paternity cases. In this laboratory activity, you will enter into the role of a forensic scie...

Olive oil is made by pressing or extracting the rich oil from the olive fruit. It seems like a simple matter to press the olives and collect the oil, but many oil extraction processes exist for the many different types of olives grown around the worl...
