Two Classifications* of Cells O Prokaryotic Cells 1st form of life O Have NO nucleus – DNA is free (called the “nucleloid”) O ONLY form Unicellular organisms (one-celled) O Example: Bacteria (e. coli, staph, salmonella) O O Eukaryotic Cells Evolved from prokaryotes O Have a nucleus with bundled DNA O Can form unicellular or multicellular organisms. O Example: Amoebas, plants animals, fungi, protists O *Note: There many TYPES of cells (skin, muscle, hair, sex, etc.,); these are the two categories that ALL cells fall under! It is the DNA within cells that controls what type of cell they will be. Cell Organelles Organelle & Function *Cell Membrane: Outer cell lining for protection *Cytoplasm: Jelly-like liquid that organelles float in *Nucleus: “Control center” that contains organism’s DNA *DNA: The hereditary material of organisms *Vacuoles: Store nutrients and waste *Mitochondria: Jelly-bean shaped producers of energy (ATP) for cell Plant Organelles PLANT-SPECIFIC organelles: *Cell Wall: Gives plant cells shape and structure (rigidity), made of cellulose *Chloroplast: Site where photosynthesis in plant cells occurs *Large central vacuole: Stores waste and water EVALUATE: What are some similarities between plant and animal cells? What do you notice about the vacuole of the plant cell? Why do you think plants evolved to have cell walls and animals did not? Parts of a Cell 8th Grade Science Monday, April 15, 2013 A cell is like a… 8th Grade Science Monday, April 15, 2013 Draw and label an analogy of the cell to something you are familiar with. Possibilities: a school, an airport, a factory, a mall, the solar system, etc. Example: In a grocery store, the sliding doors are like the cell membrane because it decides what goes in and out of the store. The shelves are like the vacuoles because they store materials. The workers are like the mitochondria because they are the energy of the cell, and the store manager is like the nucleus because they tell the store and the people in it what to do. 8th Grade Science Do Now Tuesday, April 16, 2013 For the topographic maps below, a) Identify the landform shown. b) Explain which one you think would be the easiest to climb and why.

The student knows that the Law of Conservation of Energy states that energy can neither be created nor destroyed, it just changes form. The student is expected to: (A) investigate methods of thermal energy transfer, including conduction, convection, and radiation; (B) verify through investigations that thermal energy moves in a predictable pattern from warmer to cooler until all the substances attain the same temperature such as an ice cube melting Body Systems 8th Grade Science Wednesday & Thursday, April 17 & 18, 2013 Human Body Systems - Musical Review - Circulatory - Respiratory - Skeletal - Muscular - Digestive - Excretory - Reproductive - Integumentary - Nervous - Endocrine Body Systems Card Match 8th Grade Science Wednesday & Thursday, April 17 & 18, 2013 With your table, match: --Body system name --Description of system --Examples of organs in the system Body Systems Card Match 8th Grade Science Wednesday & Thursday, April 17 & 18, 2013 SKELETAL SYSTEM Supports the body; works with muscles for movement, produces red blood cells.

When she ordered us to the stoves to prepare our assignments, she said, “Now don’t forget to use wooden spoons.” As I stirred my sauce, I contemplated the physics behind the mystery of the wooden spoon and decided it must have something to do with heat conduction. I approached Mrs. Jones to test my theory. “Why wooden spoons?” I asked. Do you know why Mrs. Jones wanted the class to use a wooden spoon? 8th Grade Science BRAIN BREAK Wednesday & Thursday, April 17 & 18, 2013 “Because, she replied, “if I have to sit here listening to all your metal spoons banging against metal pots, I’d go nuts!” Schlitterbahn!! – page 63 8th Grade Science Wednesday & Thursday, April 17 & 18, 2013 Schlitterbahn Opens Longest Waterpark Ride in the World Look for examples of…. • Conduction • Convection • Radiation Energy 8th Grade Science Wednesday & Thursday, April 17 & 18, 2013 Using the cheer: conduction, convection, radiation Write an example of each.
