Scientific method includes:
Hypothesis: the starting point of your investigation, a proposed explanation based on limited evidence Question: what you are exploring, it is not in the book, but it literally means question Experiment: a way to explore your question and test your hypothesis Experimental group: the people or beings of subjects that you are studying, the group that experiences the experimental intervention Control group: a group that does not experience the experimental intervention Placebo: fake treatment Placebo effect: effect that we see when members of a control group display a measurable response to a placebo Independent variable: factor being deliberately changed in the experiment Dependent variable: measured result of an experiment, seen in both the experimental group and the control group Sample size: number or subjects in the experiment Result: measurable by units, what you learned Evidence based conclusion: your result and seeing how it relates to your hypothesis Scientific theory: a hypothesis that is supported by many years of rigorous testing and thousands of experiments Five functional traits of life: Growth: And increase in the organism's size as the number of cell making up the organism increases. Reproduction: the process of producing new organisms, offspring are similar but not necessarily identical to their parents in general structure, function, and properties. Homeostasis: organisms maintain a stable internal environment, even when the external environment changes. Sense and respond to stimuli: organisms respond to stimuli in many ways, they may move toward a food source r away from a threatening predator. Obtain and use energy: all living beings require an input of energy to power their activities. organisms obtain energy from food (which they either produce themselves or consume from the environment). Chemical reactions convert that energy into usable forms. The sum total of all these reactions is metabolism. Review of chemistry, important terms:

Draw it outSection 04: Yin Yoga
Yin is a slow stationary practice with poses being held from 1-5 minutes allowing connective tissue to safely stretch while activating the flow of energy through the Meridians and having a positive affect on students. This practice is based off of Traditional Chinese Medicine. This practice implements biology because Yoga helps lower stress hormones that compromise the immune system its also conditioning the lungs and respiratory tract, stimulating the lymphatic system to release toxins from the body, and bringing oxygenated blood to the various organs to ensure their optimal function is there. We will learn about DNA and how it makes the components that we covered the week beforeWeek of August 6 to 10Dna: Deoxyribonucleic acidCh. 7, pg. 122 We will talk about what DNA is and how carbs, proteins, and fats are coded and then talk about food and nutrients. DNA: is the molecule of heredity, common to all life forms, that is passed from parents to offspring.

Chapter 2: elements of Life
Five functional traits of life, pg 23:
Growth: And increase in the organism's size as the number of cell making up the organism increases.
Reproduction: the process of producing new organisms, offspring are similar but not necessarily identical to their parents in general structure, function, and properties.
Homeostasis: organisms maintain a stable internal environment, even when the external environment changes.
Sense and respond to stimuli: organisms respond to stimuli in many ways, they may move toward a food source r away from a threatening predator.
Obtain and use energy: all living beings require an input of energy to power their activities. organisms obtain energy from food (which they either produce themselves or consume from the environment). Chemical reactions convert that energy into usable forms. The sum total of all these reactions is metabolism.
Review of chemistry, important terms:
Activity: work in groups of three or four, split up the words in the list into groups of four and look for the definitions in the book. Then share the definitions with each other:

Review of chemistry, important terms:
- Element: a substance whose atoms all have the same number of protons, same atomic number
- Matter: anything with mass, physical substance
- Atom: basic unit of a chemical element
- Proton: subatomic particle with positive electric charge, equal in size to an electron but of opposite charge
- Electron: subatomic particle with a charge of negative electricity, found in all atoms, primary carrier of electricity
- Neutron: subatomic particle of about the same mass as a proton but without an electric charge, present in all except those of ordinary hydrogen
- Monomer: a molecule that can be bonded to other identical molecules to form a polymer
- Polymer: a substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together
- Nucleus: positively charged central core of an atom, has protons and neutrons
- Organic molecule: composed of carbon atoms in rings or long chains to which are attached other atoms such as hydrogen, oxygen, and nitrogen
- Inorganic molecule: composed of other elements, not a combination of hydrogen and carbon
- Carbohydrate: large group of organic compounds, include sugar, starch, and cellulose
- Monosaccharide: any of the class of sugars that cannot by hydrolyzed to give a simpler sugar
- Protein: built from building blocks called amino acids
- Lipid: organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents, oils and waxes
- Nucleotide: a compound consisting of a nucleoside linked to a phosphate group, nucleotides form the basic structural unit of nucleic acids such as DNA
- Nucleic acids: a complex organic substance present in living cells, expecially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain
- Macromolecules: a molecule containing a very large number of atoms, such as a protein, or synthetic polymer
Activity: work in groups of three or four, split up the words in the list into groups of four and look for the definitions in the book. Then share the definitions with each other:
Types of bonds:
- Ionic bond: the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion. Ionic bonds require an electron donor, often a metal, and an electron acceptor, a nonmetal.
- Covalent bond: the sharing of electrons between atoms. This type of bonding occurs between two atoms of the same element or of elements close to each other in the periodic table. This bonding occurs primarily between nonmetals; however, it can also be observed between nonmetals and metals.
- Hydrogen bond: a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

Components:
Dissolving:
- Phospholipids: a lipid with a phosphate group in its molecule
- Hydrophobic: does not like water
- Hydrophilic: likes water
Dissolving:
- Solvent: able to dissolve other substances
- Solute: component in a solution, what is dissolved in the solvent
- Solution: a mixture, with a solute in a solvent
| | |
Water terms:
- Polar molecule: must contain polar bonds due to a difference in electronegativity between the bonded atoms
- pH: is a measure of hydrogen ion concentration; a measure of the acidity or alkalinity of a solution
- Acid: Solutions with a pH less than 7 are acidic
- Base: pH greater than 7 are basic
- Hydrogen bonds in water: Polar molecules, such as water molecules, have a weak, partial negative charge at one region of the molecule (the oxygen atom in water) and a partial positive charge elsewhere (the hydrogen atoms in water).
- Adhesion: is the tendency of dissimilar particles or surfaces to cling to one another
- Cohesion: cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another, water is attracted to water
