A French chemist who studied electrically charged objects and proposed two types of electricity.

Vitreous and resinous; Du Fay's classification of electrical charges.

The type of electric charge that attracts negative charges; later named by Franklin.

The type of electric charge that repels positive charges; later named by Franklin.

Similar charges push each other away, a phenomenon observed by Du Fay.

Different charges pull towards each other, as noted by Du Fay.

Materials that allow electricity to flow through easily, distinguished by Du Fay.

Materials that resist electric flow, preventing it from easily passing through.

Electricity found in nature, such as during lightning, noted by Franklin.

An experiment showing how lightning is a form of natural electricity; involved a kite and key.

A self-educated inventor, scientist, and politician, renowned as a Founding Father.

Franklin's formal education ended at age 10; he thrived independently.

Franklin established a printing business in Philadelphia and became Pennsylvania's official printer.

By 1748, Franklin retired to focus on science and philanthropy after accumulating wealth.

Franklin conducted groundbreaking experiments on electricity, challenging supernatural theories.

In 1752, Franklin famously flew a kite to study electricity during a storm.

Franklin found that pointed electrodes conduct electricity better than spherical ones.

From 1764-1765, he charted the Gulf Stream to improve naval navigation.

Franklin was a key figure in the founding of the United States.

"Do not squander Time; for that's the Stuff Life is made of."

A device that safely directs lightning to the ground, invented by Franklin.

A powerful ocean current that flows eastward across the North Atlantic, named by Franklin.

Eyewear invented by Franklin allowing vision correction for both distance and near.

A musical instrument crafted from glass bowls that produces notes when rotated.

A historic document drafted by Franklin among other Founding Fathers.

The current that runs eastward and was charted by Franklin, leading to the Gulf Stream.

Clouds containing electrical charge, demonstrated through Franklin's experiments.

Franklin chose not to patent his inventions, sharing them freely with the world.

One of Franklin's inventions designed to maximize heat output while minimizing fuel use.
