What causes the seasons on Earth? 

Background Information

Weather is always changing. Humans have been dividing up the year based on these changes in weather for thousands of years. A division of a year based on weather is called a season. Different regions of the Earth have different names for seasons and different types of seasons. The most common seasonal names used are Winter, Spring, Summer, and Fall.

A novel activity that demonstrates one of the effects of a microgravity environment. In this exercise, the structure of a flame is filmed while simultaneously plotting the acceleration of the system as it is released and experiences freefall. The apparatus is low-cost, possibly using only scrap materials found in the classroom. A PocketLab One is paired with a smartphone and used to collect the data.  Conceptually, the exercise is straightforward, though considering noise in the data, limits of the system, and chemistry applications could easily enrich the content.

Although there are a number of Web-based screen animations illustrating Kepler’s Law of Equal Areas, there are virtually no widespread physical demonstrations using actual hardware—at least not until Ozobot made the scene!  Now with Voyager and Ozobot working together as a team, the motion can be visualized and studied quantitatively

Over the past twenty years, scientists have discovered hundreds of what are known as exoplanets—planets that orbit stars outside of our own solar system.   Different groups of scientists worldwide have used a variety of methods to detect these planets.  In this lesson we will investigate a method that has been quite fruitful in finding exoplanets as a result of the Kepler Mission, launched by NASA in 2009.  Another similar mission is CoRoT, led by the French Space Agency.  These missions identify exoplanets by a method called transit, in which the b
