Day 1 • Scientific Method Review
Scientific Method • So what’s really involved….go to the next slide…..
Words to know (define) • Observation • Hypothesis • Independent Variable • Dependent Variable • Control Group • Experimental Group
Control Group vs. Experimental Group Click here for a controlled vs. uncontrolled experiment! What’s wrong with this? Water
Peer Review • Working together is important in science…COLLABORATION • Important to verify the validity of scientific research • Anonymous group of experts in that field
Practice Experimental Scenario #1 • A student investigated whether ants dig more tunnels in the light or in the dark. She thought that ants used the filtered light that penetrated the upper layers of earth and would dig more tunnels during the daytime. Ten ant colonies were set up in commercial ant farms with the same number and type of ants per ant farm. The same amount of food was given to each colony, and the colonies were in the same temperature. Five of the colonies were exposed to normal room light and five were covered with black construction paper so they did not receive light. Every other day for three weeks the length of the tunnels was measured in millimeter using a string and a ruler. Averages for the light and dark groups for each measured were then computed. The averages are listed in the following chart. Independent variable? Dependent Variable? Things to keep constant? Control group? Experimental group? Conclusion? More Practice Problems Click me!

Day 2 Classification and Taxonomy • Review and discuss
Characteristics of Life • Genetic code • Made up of one or more cells • Respond to stimuli • Grow and develop • Use and obtain resources to produce energy • Reproduce • Maintain Homeostasis • Evolve over time
Genetic Code • All living things have DNA made up of the same types of nucleotides (ATGC) • These nucleotides code for the same 20-23 Amino Acids • How are all living things so different? • Because we have different sequences of DNA=…. • different SEQUENCES of our Nucleotides=Different sequences of AMINO ACIDS= .. • different living things
Both SEXUAL and ASEXUAL reproduction require REPLICATION of DNA in order to produce offspring
Survive and Reproduce!!! All living things are trying to…????
Classification of Life • 3 Domains • Archaea • Bacteria • Eukarya • 6 Kingdoms • Archaeabacteria • Eubacteria • Protista • Fungi • Plant • Animal
Cladograms • Tree-like diagram showing evolutionary relationships
EOQ1 Test Question review • Questions: 10, 11, 24, 25, 31, 34, 35, 36, 38, 42, 43, 44, 49, 54, 57, 60

Day 3 Water, Carbs, and Lipids • Review and discuss
Properties of Water • Water POLARITY allows… • Versatility as a solvent • Capillary action-adhesion and cohesion (high surface tension) • Expansion upon freezing • Energy released when Hydrogen bonds form in ice • High specific heat= temperature moderation
Macromolecules • Polymer • Monomer
Carbohydrates • Monomer: monosaccharide (glucose) and disaccharides (sucrose, lactose, maltose) • Functions: • Glucose makes ATP (energy) in cell respiration (instant energy) • Polymer: polysaccharides (glycogen, starch, cellulose) • Functions: • Glycogen/Starch Energy storage in animals/plants (chains of glucose) • Cellulose structure…CELLULOSE…plant cell walls
Carbohydrates • Divided into 3 main groups: • Monomer: Monosaccharide or Disaccharide • Polymer: Polysaccharide • Link between monomers is called: GlycosidicLinkage • Formed by a dehydration/condensationreaction • Always have Carbon, Hydrogen, and Oxygens • Cx(H2O)y • Common name: sugar • End with suffix “-ose” • Function: Energy/fuel, structure,storage • GLUCOSE!!!! • What all cells need for energy
Carbs in the Living world • Click here to check it out
Lipids • Hydrophobic • Fats (triglycerides) • Phospholipids • Oils • Waxes • Steroids • cholesterol • Major Function: • ENERGY STORAGE • Water proofing
Triglycerides • Made of mostly carbon and hydrogen…some oxygen • Usually not soluble in water • HYDROPHOBIC!!! • Not a polymer but is made of molecular units • Glycerol + 3 Fatty Acids= FAT • Linkage is called ESTER linkage • Dehydration reaction • Function • Energy storage • Insulation • Waterproofing • Water synthesis
Phospholipids -make up the cell membrane -Have Phosphate group (charged) with two fatty acid chains attached -makes the cell membrane hydrophilic AND hydrophobic

EOQ Test Practice • Do Not write in test book • QUESTIONS:Water: 2, 12, 17, 20, 21, 26, 40, 45, 47 Carbs/Lipids: 1, 7, 13
Making It Make Sense • Umbrellas • Create an umbrella for carbs and one for lipids and complete • Water Square • Copy and complete for properties of water • Include a picture representing each property Property 1 Property 2 Water Property 3 Property 4
Day 4 Nucleic Acids, Proteins and Enzymes • Review and discuss
Nucleic Acids Central Dogma Of Biology DNA RNAProtein • Monomer: Nucleotide • Structure of a Nucleotide • Made of a phosphate group, a sugar (ribose or deoxyribose), and nitrogenous base • Polymer: Chain of nucleotides (nucleic acids) • Contain Carbon, hydrogen, oxygen, phosphorus, and nitrogen • Deoxyribonucleic acid (DNA) • Ribonucleic Acid (RNA) • FUNCTION: Store and transmit hereditary, or genetic information…makes PROTEINS that do everything!
