​Scientific Instruments

​Scientists developed new tools and instruments to make precise observations that the scientific method demanded.

​The first Microscope was invented in 1590 by a Dutch maker of eyeglasses, Zacharias Janssen.

• Looking at far off objects, such as armies and ships on the horizon.

• Looking at Microscopic organisims and other Phenomon.

• Looking at planets and moons.

• Tp improve vision.

​A Dutch drapery merchant and amateure scientist named Anton Van Leeuwenhoek used a microscope to observe bacteria swimming in tooth scrappings.

​In 1643, one of Galileos's students, Evangelista Torricelli developed the first mercury barometer, a tool for measuring atmosphere pressure and predicting the weather.

​In 1714 , German Physicist Gabriel Fahrenheit made the first theromometer to use mercury in a glass. Fahrehnheit theromoster measured water freezing at 32°.

​

​A Swedish astronomer, Anders Celsius created another scale for the mercury thermometer in 1742. Celsius scale showed freezing at 0°.

Medicine and the Human Body During the Middle Ages, European doctors

had accepted as fact the writings of an ancient Greek physician named

Galen. However, Galen had never dissected the body of a human being.

Instead, he had studied the anatomy of pigs and other animals. Galen

assumed that human anatomy was much the same.

​

In the 1500s, a Flemish

physician named Andreas Vesalius proved Galen’s assumptions wrong.

Vesalius dissected human corpses and published his observations.

His

book, On the Structure of the Human Body (1543), was filled with detailed

drawings of human organs, bones, and muscles.

Multiple Choice

Andreas Vesalius proved the anantomy of a human being?

• Is similar to a pig

• Unique

• Differ from person to person

• Is simular to great apes.

​Robert Boyle pioneered the use of the scientific method in chemistry.

​

Studied ancient alchemy (Alchemists believed that base metals such as lead and copper could be transformed into silver and gold).

​

Applied his observations and experimentation to the principles of the scientific method to be used in chemistry.

​

​Challenged Aristotle's idea that the physical world consisted of four elements earth, air, fire, and water.

​

​Proposed that matter was made up of smaller primary particles that joined together in different ways.
