Watch the GPB Chemistry video #303: Electrons in Atoms and take notes.
For Wednesdsay, 9/2 – Dress for Lab!
Watch GPB Video #304 – Electron Distributions and take notes:
Today, we will review calculating atomic mass, complete the “Beanium” Lab with analysis and if there is time, we will start discussing Nuclear Chemistry, focusing on the nucleus of the atom. Here is the power point for that lesson:
Also, here is the beanium lab and the atomic mass worksheet from Monday, in case you lose your copy,
Beanium Lab (Average Atomic Mass)
We took review atomic theory, took notes on atomic structure and worked on some classwork on atomic structure. Here are links to the power point and the classwork below.
4th period people: We took the SLO today so we may not have had time to get to atomic structure until Monday.
Watch the GPB Chemistry video #302 – The Structure of the Atom and take notes.
Research the following people/events,take notes, and then create a chronological timeline of the development of the atomic theory. This is an in-class assignment.
Quantum Mechanical Model
Plum Pudding Model
Dalton’s Atomic Theory
Gold Foil Experiment
Cathode Ray Experiment
Aristotle/ Democritusnotes page
Watch the GPB Chemistry video #301: The Development of the Atomic Theory and take notes:http://www.gpb.org/chemistry-physics/chemistry/301
Plus – Finish reading the article, “So Tired in the Morning – The Science of Sleep” and answer the questions. You received this in class today.
So Tired in the Morning article
– Id lab equipment
– Lab Safety Equipment location
– Scientific method:: know the parts of the method, be able to id then in an experiment, accuracy vs. precision, and significant figures in calculations
– Matter physical and chemical properties/changes, pure substances (elements & compounds) vs. Mixtures (homogeneous & heterogeneous), be able to solve density problems
-Heat: define heat, temperature, endothermic and exothermic; be able to solve q = mC(delta)T problems, answer questions about goldfish lab
Due Friday, 8/14
Research the 5th state of matter and write the name and definition on a piece of paper and hand to me tomorrow.
