Science Study Guide, Quarter I

Quarter I, Chemistry

ü  Be able to identify errors in the model of an atom by considering information from the Periodic Table. (videos and notes) See Homework #1

Example: Does Nitrogen (N) have 10 protons and 8 neutrons? Why not? Does Nitrogen have 6 electrons on its first shell? Why not?

ü  Be able to choose any atom and draw an accurate representation of the atom and calculate the neutrons properly. (video and notes)  See Homework #1

ü  Describe the covalent bond of H₂O. (remember to discuss the electrons and the valence shells)  (videos and notes)  See Homework #3

ü  Explain why the sand did not dissolve in the water from the lab conducted at school.  (notes and videos)  See Homework #3

ü  Describe the ionic bond of NaCl. (remember to discuss the electron and the valence shells) (videos and notes)  See Homework #3

ü  Explain why the salt did dissolve in the water from the lab conducted at school. (videos and notes) See Homework #3

ü  Explain some similarities and some differences about either (pick 2 pairs): Mixtures and solutions, Compounds and molecules, Molecules and ions, Pure elements and atoms or two of your choice.  (readings/copies and notes in notebook)

ü  How is the Periodic Table organized? Be specific by using chemical and physical properties, periods, groups, energy shells and more. Include a brief history of the periodic table. (videos, readings, and notes) See Homework #4

ü  Discuss which theory or discovery has influenced chemistry the most.  (timeline in notebook and notes)

ü  How does chemistry affect your world now? Include information about the global water supply, global health, and world nutrition.  (notes from iPad application in science notebook) See Homework #2 for a little information

ü  Make a connection between one historical event in chemistry and one current event that has made something possible today. (Timeline in notebook and iPad notes, your knowledge)

ü  How do you believe chemistry will improve people’s lives in the future? (personal investigation or use of space related article on blog) Include information about the global water supply, global health and world nutrition (iPad notes)  

ü  Design a question or questions about the future of chemistry. (Your brain, your knowledge, your curiosity) 

The Promise and Perils of Mining Asteroids

A new company has joined the ranks of entrepreneurs looking to space for their next economic opportunity.

There are some 9,000 asteroids described as "near-Earth," and they contain several classes of resources that entrepreneurs are now eyeing as economically valuable.
Elements such as gold and platinum can be found on some asteroids. But water, silicon, nickel, and iron are the elements expected to become central to a space "economy" should it ever develop.

Water can be "mined" for its hydrogen (a fuel) and oxygen (needed for humans in space), while silicon can be used for solar power systems, and the ubiquitous nickel and iron for potential space manufacturing.
