arely passing grade. This made it difficult for him to find
work in a university after graduation.
3. Arrhenius was interested in physical chemistry, biology,
astronomy, and meteorology.
4. Arrhenius suggested that life may have spread from one part
of the universe to another when living spores from one planet
escaped their atmosphere and were then pushed along by

Skill Sheet 16.1: Benjamin Franklin
1. Franklin learned through reading, writing, discussing, and
experimenting.
2. Franklin’s hypothesis was that lightning is an example of a
large-scale discharge of static electricity.
3. Franklin’s reported results were that the loose threads of the
hemp stood up and that touching the key resulted in a static
electric shock. He concluded that the results were consistent
with other demonstrations of static electricity; therefore,
lightning was a large-scale example of the same phenomenon.
4. If the kite had been struck by lightning, the amount of charge
coming down the hemp string would most likely have
electrocuted Franklin.

radiation pressure to other places in the universe until they
landed on another hospitable planet.
5. Arrhenius was one of the first to explain the role of
“greenhouse gases” in warming the surface of the planet. He
also proposed that humans could change Earth’s average
temperature by adding carbon dioxide to the atmosphere.
