lab 9

Lab nov 6

• Objective: to observe the different characteristics of of different members of the animal kingdom
• Materials: microscope, live and mostly dead specimens, pencil paper

lab 8

• Biodiversity
• Goal: better understand the differences in different types of living organisms
• Bacteria: single cell, no nuclei, mostly heterotrophic, some decomposers, parasites, mutualists, some autotrophs, chemoautotrophs
• Bacilli shape, coxus shape, spirilli shape
• Protists: large size, single or multicellular, membrane bound organelles, complex DNA and nucleus
• Mix of parasites, autotrophs, heterotrophs, primarily aquatic
• Plants: lower plants are primitive and simplistic and upper plants
• Lower: things like moss
• Higher: plants like bushes and flowers and such
• most are photosynthetic
• Materials: microscopes, prepared slides

Lab 7

• Sickle cell anemia: identifying sickle cells which can cause blood clots and lack of oxygen to the body parts resulting in organ failure
• Gel electrophoresis to seperate hemoglobin proteins, sickle cell is negative charged and will go positive side
• Materials: electrophoresis machine, pipet, gel plate, salty solution.
• Transcription and translation- meant to show us how genes work
• Two step process: transcription in the nucleus and Translation in the cytoplasm
• Genetic architecture: get a better sense of how alleles fit together, and determine what the parental phenotypes were through looking at the offspring
• Materials: Punnet squares, Rebop, random alleles in an envelope.

  

lab 6

Biological chemicals lab

• Testing to see examples of chemicals in food
• Materials: testing solutions, benedict’s reagent, Sudan 3, biurets reagent, water, chicken broth, egg proteins, lugols iodine
• Looking for color change in different foods
• Measuring vital signs at rest
• Measure resting heart rate
• Measure blood pressure systolic and diastolic
• Materials monitoring systems

Lab 5

Lab October 2nd

Mitosis and cytokinesis same thing

Most of the cells life is spent in interphase

Five stages of mitosis

• Prophase-  appearance of chromosomes
• Metaphase- chromosomes line up along equator of cell
• Anaphase- splitting of chromatids
• Telophase- segregation of chromosomes
• Cytokinesis- two new cells
  
  
  Mateirials: HCl, tip of root, dye, H2O,

lab 4

materials: TLC strip, Microscope, elodea, other plant, water, solvent

The goal of todays lab was to understand how plants store there energy and how they get their pigment from the son. we did this by placing chlorophyll on the TLC strip, and also by looking at the elodea and other plant under the microscope and observed the pigment change and levels

Lab 3

Materials: auger plate, dropper, methyline blue, IKI,  Petri dish, glucose, dialisis tubing, weigh bags, elodea, NaCl, charcoal

Goal: Our goal for the experiment was to explore the role osmosis and diffusion play in the cell measure the difference traveled between IKI and Methyline blue in the auger plate by the end of it the methylene blue had expanded 1mm all around and the IKI had expanded 2mm. then we looked at the difference between an Isotonic and hypotonic elodea, and charcoal under the microscope, and saw elements of Brownian movement in both.
