The heliocentric theory is belief that the sun, not the Earth, is at the center of the universe. ]]> 2023-05-18 15:56:21 UTC https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2596461987 4tluu882 https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2596468679 Tycho Brahe charted the positions of hundreds of stars, using careful observation and detailed recordings. 
Today, all scientists follow Brahe example by taking careful notes of their observations and findings. ]]> 2023-05-18 16:01:48 UTC https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2596468679 4tluu882 https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2596474011 Johannes Kepler observe that planets moved in oval (elliptical) orbits, not circular ones. ]]> 2023-05-18 16:06:12 UTC https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2596474011 4tluu882 https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2596481904 Galileo Galilei was the first person study the sky with a telescope. He also was the first to use experiments to test his theories / ideas.
He supported Copernicus' heliocentric theory of the universe which got him into trouble with the Catholic Church. 
Galileo was also interested in mechanics--the study of objects and motion. ]]> 2023-05-18 16:13:10 UTC https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2596481904 4tluu882 https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2596485492 Isaac newton is best known for creating the laws of gravity and motion. 
He also invented a type of math known as Calculus. ]]> 2023-05-18 16:16:21 UTC https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2596485492 4tluu882 https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2596494777 A microscope is an experimental tool for examining objects that are too small to be seen with the naked eye.

Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.]]> 2023-05-20 00:55:42 UTC https://padlet.com/4tluu882/ndf078eu8hqkso3a/wish/2598073897
