SECOND SEMESTER
(04/04 to 04/08)
Topic: Protein Synthesis
Standard: HS-LS1-6 (Molecules to Organisms)
Objectives (Students will be able to understand that):
- Gregor Mendel was an Austrian monk that studied science and math at the University of Vienna
- Mendel established rules of heredity while studying garden peas: the law of segregation, the law of independent assortment, and the law of dominance.
- Mendel is widely regarded as the father of modern genetics.
- Before Mendel’s experiments, scientists largely accepted the blending theory of inheritance.
- After allowing the plants to self-pollinate, pure strains called the Parental generation, or P generation, were produced.
- Crosses within the P generation produced the F1 generation, a generation of hybrids displaying only dominant traits.
- Crosses between F1 generation plants produced the F2 generation, a generation where 75% of plants displayed dominant traits, and 25% displayed recessive traits.
- Crossing traits with Punnett squares helps determine the probability of which genotype an offspring might inherit.
- Crossing a single trait, such as flower color, is known as a monohybrid cross.
- Crossing two traits, such as flower color and plant height, is known as a dihybrid cross.
(11/14 to 11/18)
Topic: Atomic Structure
Standard: HS-LS1-2, HS-LS2-2, HS-LS2-7 (Atomic Structure)
Objectives (Students will be able to understand that):
- A solution is a uniform mixture of one substance in another, the substance being dissolved in a solution is the solute, and the substance that does the dissolving is the solvent.
- The concentration of a solution is a measure of the amount of solute dissolved in a given volume of solvent.
- Solutions can be mixtures of solids, liquids, or gases.
- Neutral solutions have an equal number of hydrogen (H+) and hydroxide (OH–) ions.
- Acids have more hydrogen ions (H+) than hydroxide ions (OH–). Acids taste sour and can be corrosive.
- Bases contain more hydroxide ions (OH–) than hydrogen ions (H+). Bases taste bitter and feel slippery.
- The pH scale ranges from 0 (very acidic) to 14 (very basic).
- Buffers maintain a stable pH by neutralizing small quantities of acids or bases.
- The bicarbonate buffer system is a homeostatic mechanism that controls the pH of human blood.
Homework:
(09/27 to 10/08)
Topic: Atomic Structure
Standard: HS-LS1-2, HS-LS2-2, HS-LS2-7 (Atomic Structure)
Objectives (Students will be able to understand that):
- Covalent bonds form when two atoms share electrons.
- Ionic bonds form when one atom transfers electrons to another atom.
- Hydrogen bonding occurs when hydrogen bonds with a negatively charged atom.
- Coefficients tell how many molecules are present and subscripts tell how many atoms of an element are present. If there is no expressed coefficient or subscript, assume it is 1.
- To find the total number of atoms of a specific element in an equation, multiply the coefficient by the subscript.
- Exergonic reactions involve a net release of energy and endergonic reactions involve a net absorption of energy.
- Enzymes are catalysts that accelerate chemical reactions.
- Redox reactions are chemical reactions that involve the transfer of electrons between atoms.
- In oxidation reactions, a reactant loses 1 or more electrons and becomes positively charged.
- In a reduction reaction, a reactant gains 1 or more electrons and becomes negatively charged.
(09/13 TO 09/24)
Topic: Atomic Structure
Standard: HS-LS1-2, HS-LS2-2, HS-LS2-7 (Atomic Structure)
Objectives (Students will be able to understand that):
- Atoms consist of 3 kinds of subatomic particles: protons, neutrons, and electrons.
- The nucleus is the center of an atom and contains the atom’s protons and neutrons.
- Protons are positively charged, neutrons have no charge, and electrons are negatively charged.
- An element’s atomic number is determined by its number of protons.
- An element’s atomic mass is determined by its number of protons + neutrons.
- Electrons spin around an atom’s nucleus in energy levels.
- Atoms have a neutral charge because they contain the same number of protons and electrons.
- The number and arrangement of electrons in an atom determines if it will combine to form compounds.
- Compounds have different physical and chemical properties than the atoms that compose them.
Homework 1:
(08/16 TO 08/27)
Topic: THE UNIFYING THEMES OF BIOLOGY
Standard: HS-LS1-2, HS-LS2-2, HS-LS2-7 (Unifying Themes of Biology)
GOALS:
- Join and become familiar with Google Classroom
- Explore Google Drive (Docs, Sheets, Slides)
- Sign out and receive text books
- Learn how to upload an assignment to Google Classroom
- Student Handbook: Redos
- Website link
Objectives (Students will be able to understand that):
- Biology is the study of all living things.
- There are 6 themes that unify the study of biology.
- The cell is the basic unit of structure and function.
- Unicellular organisms are made up of one cell, whereas multicellular organisms are made up of more than one cell.
- Homeostasis is the state of internal stability.
- DNA is a large molecule containing the hereditary material of a cell.
- Unicellular organisms typically produce offspring identical to themselves via asexual reproduction.
- Multicellular organisms typically produce distinct offspring via sexual reproduction.
- Genes are short segments of DNA that carry the instructions for a single trait of an organism.
