  1. Physical Science Semester 2 Unit 4 Matter

  2. 2/3/14Week of 2/3 to 2/7 • Entry Task • What are the “two pillars of science” that Einstein’s famous equation joined with c2 ? • Explain what Lavoisier became famous for. • Explain what Faraday became famous for.

  3. Today’s Agenda • Finish notes on movie. • Please take note of people, year and place, and what they accomplished as a scientist. • You will turn your notes in tomorrow after discussion.

  4. 2/3/14 • Exit Task • Give a detailed example of how society influences science and technology and vice versa. • This example can be from the movie or real life.

  5. 2/4/14 • Entry Task • Describe what you know about the structure of atoms. • Homework: read pages 278-290. Answer questions #1-7 on page 284 AND #1-6 on page 290. Due Friday 2/7/14.

  6. 1812 – Michael Faraday, electricity/magnetism, London, only gentleman are scientists 1885 Einstein as a child – his family designed lighting for the city 1771 – Antoine Lavoisier, France, Conservation of Mass, French Revolution, he gets guillotine—disliked tax collector 1897 Einstein in high school, poor student, fascinated by light 1846 – Faraday realizes electricity and magnetism are connected, invents electric motor, names the “invisible light” electromagnetism 1722- Emilie du Chatalay, France, “before her time”, translated Newton’s principia and realized he had made an error, velocity should be squared, fell in love with poet Voltaire, died at 43 after childbirth 1905 – Einstein’s miracle year, Germany, 5 papers, including E=mc2 in 3 pages 1919 – Fame finds Einstein via Max Planck. He divorces Mileva, marries cousin 1907 – Berlin, Germany; Lisa Meitner becomes first woman professor (1912)of physics 1920-30 “Golden Age of Nuclear Research” 1930’s – Nazis drive out Jewish intellectuals; Einstein leaves in 1933; Meitner barely escapes in 1938 1938 – Sweden, Robert Frisch (nephew) and Meitner “split the atom” realizing that lost mass is converted directly to energy during nuclear fission 1944 – Hann awarded prize for discovering nuclear fission (Meitner got little credit) 1942 Manhattan Project in US; bombs contain only a couple pounds of Uranium and Plutonium

  7. Today’s Agenda – create a timeline • You will be placed into a team. • Compile your notes so that everyone has complete notes to turn in. • 1 = Energy • 2 = mass • 3 = light • 4 = velocity (speed of light squared) • 5 = development of e=mc2, • 6 = confirmation of e=mc2 • Nominate a recorder, facilitator, data person, speaker. • WRITE CATEGORY ON TOP OF CARD. • One scientist per notecard. • Fill in Year, NAME, Nationality, Concept, Experiment(s), Challenges Faced. • These cards will go on timeline from 1700 to 1950. • Your team will present your cards.

  8. 2/4/14 • Exit Task • Explain how one scientist’s ideas evolved based on the work of other scientists. • Hold onto your notes!!! You will need them for the timeline project! To be continued Thursday.

  9. 2/5/14 • Entry Task • Explain how Einstein’s equation led to the splitting of the atom. • Hold onto your E=mc2 notes!!! You will need them for the timeline project! To be continued Thursday.

  10. Today’s Agenda • Class time to work on HW: • Read pages 278-290. Answer questions #1-7 on page 284 AND #1-6 on page 290. • Due Friday 2/7/14. • Also, in C-notes form, define the following terms: • Electric charge • Proton • Neutron • Electron • Nucleus • Atomic number • Isotopes • Mass number • Energy level • Quantum theory

  11. 2/5/14 • Exit Task • You may use a textbook: • Define atomic number and mass number. • Explain how they are different.

  12. 2/6/14 • Entry Task • What further questions do you have after having completed “Einstein’s Big Idea”? • Take out your notes. Assign groups….

  13. Today’s Agenda – create a timeline • You will be placed into a team. • Compile your notes so that everyone has complete notes to turn in. • 1 = Energy • 2 = mass • 3 = light • 4 = velocity (speed of light squared) • 5 = development of e=mc2, • 6 = confirmation of e=mc2 • Nominate a recorder, facilitator, data person, speaker. • WRITE CATEGORY ON TOP OF CARD. • One scientist per notecard. • Fill in Year, NAME, Nationality, Concept, Experiment(s), Challenges Faced. • These cards will go on timeline from 1700 to 1950. • Your team will present your cards. • Presentations Last 10 minutes of class. Each team 2 minutes! • YOU WILL BE GRADED ON YOUR PARTICIPATION AS YOU WORK!

  14. 2/6/14 • Exit Task • NONE – presentations for timeline. • TURN IN YOUR NOTES on the way out of class…

  15. 2/7/14 • Entry Task • Say Something Nice • HW – Turn in. • Turn in Einstein Notes. • Turn in Entry/Exit Task Sheet

  16. Today’s Agenda • Finish any presentations from yesterday. • Take Unit 4 Pre Test • Complete the self-assessment side of the Unit Map “blue sheet”– • Rate yourself 1-4 on each of the standards in the “start unit” column

  17. 2/7/14 • Exit Task • Trade and Grade • Please turn in your Entry/Exit task sheet for the week.
