SI - 1.15.13

People of Science

 
Below is a list of names that we have discussed thus far. Try to match the descriptive terms with each person.
 
People:
Charles Darwin
Alfred Russel Wallace
Thomas Malthus
Herbert Spencer
Dr. Okazaki
Jean-Baptiste Lamarck
 
Descriptions:
Inspired Darwin's work to include the "struggle for existence" as a part of natural selection
"Differential survival and reproduction"
Did a lot of field work throughout his lifetime
"Descent with modification
A statistician
Believed that evolution occurred through "acquired characteristics"
Proposed Theory of Evolution through Natural Selection
Wrote an "Essay on the principle of population"
Known for the term "Survival of the Fittest"
Took a trip on the Beagle around the world
Came up with ideas of Natural Selection independently of Darwin
 
 

Thought Questions

What type of reasoning is used to create a hypothesis?
What type of reasoning is used to test a hypothesis?
Is the term "theory" the same as hypothesis?
How does Natural Selection Occur?
Is Natural Selection the only way evolution occurs?
What evidence supports Darwin's original ideas of Natural Selection?
What is the strongest type of chemical bond?
What is an isotope?
What isotope did Dr. Okazaki use in biological experiments?
What is the weakest type of chemical bond?
What bond holds together a water molecule?
What particle within an atom has a negative charge?
 

Atoms and Chemical Bonds

Draw the following molecules and compounds and then label any bonds, or ions with the appropriate type. Circle the nucleus and place appropriate charge symbols on atomic particles. Draw a star over the valence electrons. Indicate the atomic number and atomic mass of each element used. You may need to look at a periodic table to find out how many protons each element has.
 
Salt (Na Cl)
Nitrogen Gas Molecule
Water Molecule
2 Water Molecules bonded
Deuterium
Tritium




Welcome to my blog

Welcome to my blog!


I will be using this blog to post information given during SI sessions, and also any exam reviews that are held. Occasionally I may update with thought questions or other relevent information that may help you in this course. Please don't hesitate to ask any questions you may have about information posted here, and good luck this semester.
