How is lightning created? And what is thunder? What kind of weather creates the most lightning? This science story shows how lightning is like the spark from static electricity, but much bigger.

Beliefs about the shape of the earth have varied over the millennia, but the Ancient Greeks were able to observe that our planet is round and even Eratosthenes attempted to measure its size. It was not until explorers had fully charted the globe that most people were really able to comprehend its spherical shape.

For thousands of years, people have been using the engineering design process.

Isaac Newton was always a loner, preferring to spend his time contemplating the mysteries of the universe. When the plague broke out in London in 1665 he was forced to return home from college. It was during this period of so much death that Newton gave life to some of the most important theories in modern science, including gravity and the laws of motion.
