Transcript of 7th Grade Jeopardy Review

Jeopardy Review Game Properties of Matter Density and Earth's Structure Cells Heredity Classification 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 100 200 300 400 500 Order the levels of organization from simple to complex. Differentiate between a plant cell and an animal cell (three main differences). What is diffusion? Give the function of each of the following organelles in a cell:
Cell membrane
Cell wall
Chloroplast
Nucleus
Mitochondria Give the function of 3 different organ systems in the human body. Label the diagram drawn on the board. The density of a brick of steel is 7.7g/cm3. You melt the brick down and forge it into a mighty sword. What is the density of your sword? Describe each layer of the earth and list in order from least dense to most dense. Why do tiny particles of gold dust stay at the bottom of the pan when you're panning for gold? Describe the sorting of particles in a stream. What is matter? List three characteristics of matter. Describe the movement of particles in each of the three states of matter. How do you calculate mass, volume, and density? How does natural selection work? Give an example of an adaptation and how it helps an organism survive in its environment. Give an example and explain the difference between inherited and acquired traits. Define heredity. Compare living, once-living, and non-living things. How are organisms classified? List the orders of classification from most general to most specific. List the 5 kingdoms and describe a characteristic of each. Describe how to use a dichotomous key to identify an organism. Anything that has mass and takes up space (pretty much everything) Atoms are the smallest unit of matter. Two or more atoms combine to form a molecule. Mass, State, Ractivity Solid: Particles vibrate in place
Liquid: Particles can slide past each other
Gas: Particles spread out as far as possible bigger particles will be found at the source of the stream and particle size will decrease as the water slows down. Gold dust settles to the bottom because it is more dense than the other material in the pan Crust: Surface of the Earth Mantle: Molten rock
Outter core: Molten metal Inner core: Solid metal 7.7g/cm3 The natural movement of particles from an area of high concentration to low concentration. A plant cell has a cell wall, chloroplasts, and a large central vacuole. Cells work together to form tissues, 2 or more tissues form an organ, organs make up organ systems, and organ systems make up an organism. Cell membrane: controls what goes in and out of a cell
Cell wall: protects and supports plant cell
Chloroplast: produces food from sunlight
Nucleus: contains DNA
Mitochondria: provides energy for the cell in the form of ATP Ex:
Respiratory: provide O2 and removes waste CO2
Muscular: movement and heat production
Nervous: sensory imput and control of body systems Heredity is the passing down of traits from parent to offspring. They help to digest food in the intestines. In sexual reproduction, two parents contribute genes to the offspring. In asexual reproduction, one parent passes 100% of its genetic info the offspring. Ex:
Rabbits have long, powerful hind legs to help them escape predators. An organism has an adaptive trait that allows it to survive betterin its environment. Because it survives, it reproduces and passes the adaptation on to its offspring, so the trait becomes more common in the population. Living things have characteristics like metabolism, reproduction, growth, response to the environment, etc. Once-living thigs used to have those characteristics but don;t anymore. Non-living things never had any of the characteristics of living things. Organisms are classified based on observable properties and structure. Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species Bacteria: prokaryotic
Fungi: decomposers
Plantae: chloroplasts
Protists: unicellular eukaryotes
Animalia: multicellular eukaryotes Observe the organism carefully, read each of the options given in the key, then answer yes or no based on the description. If yes, follow the instructions given. If no, move on to the next option. Describe matter in terms of atoms and molecules. Discuss the advantages and disadvantages of maps and globes as models. A globe is good for showing relationships between continents and showing the correct sizes, but is not great for details and seeing things all at once, which is what flat maps are good for. Mass: use a triple beam balance
Volume: LxWxH (reg), water displacement (irreg)
Density: D= M/V Compare how sexual and asexual reproduction passes genetic info from parent to offspring.
