Introduction
Space education continues to capture the imaginations of students and educators alike. With the increasing focus on STEM (Science, Technology, Engineering, and Mathematics) in classrooms, hands-on activities that demonstrate real-world scientific methods are more important than ever. databot, with its versatile sensor capabilities, provides an engaging way to bring these concepts to life. One exciting application is using the transit method to identify exoplanets—a technique that has helped astronomers discover thousands of planets outside our solar system.
What is the Transit Method?
The transit method is a popular technique used by astronomers to detect exoplanets. This method involves monitoring the light from a star and observing small dips in brightness that occur when a planet passes in front of it. These dips, or transits, are telltale signs of an orbiting planet, allowing scientists to determine the planet’s size, orbit, and sometimes even its atmospheric composition.
Bringing the Transit Method to the Classroom
databot makes it easy to demonstrate the transit method to students with a simple, hands-on experiment. By using databot’s ambient light sensor, educators can easily simulate the detection of an exoplanet in the classroom. You can also use two databots where one acts as the light source and the other is sensing the change in light intensity. See the video below and setup instructions using LEGO® robotics as a great example. You can develop your own solution based on the availability of resources in your classroom, the important part is to have a light sensor to gather the data for analysis.
How to Setup and Demonstrate the Transit Method in Your Classroom
- Setup: Create a model that will pass a small object (representing a planet) in front of a bright light source (representing a star) on a regular cycle, representing the time a planet might take to orbit its star. See the LEGO® model as an example, if you don’t have LEGO® materials create your own solution.
- Data Collection: Position databot’s ambient light sensor facing the light source and start the experiment. As the object moves in front of the light, databot will record the changes in light intensity.
- Analysis: Students can then analyze the data, identifying the moments when the light dims as the object transits the “star.” This data can be used to understand the principles of the transit method and how astronomers detect exoplanets.
