Atoms

Physical Science spent time today discussing the nature of the atom. The 3 major subatomic particles were introduced (with the proton and neutron being described), as was the beginning of the development of the current model of atomic structure. Although I didn't plan it, a nice introduction of the 4 fundamental forces (gravity, electromagnetism, strong nuclear and weak nuclear) was given and generated some productive class discussion. Here are a few videos with a bit more information on that topic:

An ultra-quick overview of the 4 fundamental forces:



Now, a bit on the strong and weak nuclear forces:



And, gravity and electromagnetism:



Physics and Honors Physics continued on with their laboratory unit by completing their lab using an inclined plane to determine acceleration due to gravity and starting to use the Vernier Dynamics system to graphically and mathematically explore Newton's Second Law of Motion.
