In chemistry, eighth graders explored the periodic table of elements, often described as the ultimate map of matter. They learned to read the table like scientists—discovering how atomic numbers and atomic masses reveal information about each element’s structure, bonding potential, and the shared properties within each column. With each lesson, students grew more confident in understanding how the periodic table organizes and explains the world around us.
One question that sparked lively curiosity was: “How can an element have a negative boiling point?” To find out, students conducted a hands-on Dry Ice lab. Wearing goggles and gloves, they observed how this compound sublimates, changing directly from a solid to a gas at room temperature. They watched Dry Ice “boil” on the counter, producing dense vapor clouds, and experimented with how everyday objects reacted to the extreme cold. From squealing pennies to bubbling vapors, the lab brought to life the concept of boiling points and how temperature affects different substances on Earth.
To deepen their understanding, each student selected an element to research in depth. They created Bohr models, uncovered the discovery stories behind their elements, and explored everyday uses—from technology and medicine to construction and art. To showcase their creativity and knowledge, students designed custom T-shirts celebrating their chosen element. The results were as stylish as they were scientific!
