Sixth Grade Science Study Guide 2014-2015 8. 1. What is the formula to calculate density? “Of Life” Anything living, once living, or from something living Density = mass ÷ volume 2. When using a microscope, you should 9. never focus toward the slide. 3. 4. Give some examples of biotic factors: Animals, plants, dead animals and plants, fungi, bacteria, etc. Write a simple procedure to determine which of two baseballs can go the farthest: 10. A(n) ecosystem is all the living and nonliving things in a particular area that interact with one another. Hit each baseball with the same amount of force and measure the distance traveled. 11. Write the levels of organization in an ecosystem, from the smallest to largest level: How can you determine if a cell is prokaryotic or eukaryotic? Eukaryotic cells have a nucleus, prokaryotic cells do not. Organism, Population, Community, Ecosytem 12. _________________________________ 5. What does biotic mean? A cell has DNA that lies free in the cytoplasm inside a single rod-shaped cell. What type of cell is it? What is a compound? A chemical with two or more different elements 13. About 99% of the Earth’s atmosphere is made up of Nitrogen prokaryotic and Oxygen. 6. Describe the following Kingdoms: 14. Plantae: Multicellular, eukaryotic, autotrophic Fungi: unicellular or multicellular, eukaryotic, heterotrophic, don’t move Two hydrogen atoms and one oxygen atom 15. Animalia: unicellular, or multicellular, eukaryotic, heterotrophic, can move Give an example of a compound: H2O, NaCl, CO2 16. 7. The compound of water is made of List the levels of taxonomic classification from highest to lowest: What sort of energy is found in the spring of a closed Jack-in-the-Box? Mechanical potential energy Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species 17. What form of energy is stored in our food? Chemical potential energy Sixth Grade Science Study Guide 2014-2015 18. During energy transformations some energy is always transformed into 27. Substances that are less dense float on substances that are Thermal energy more dense. 19. 20. Scientists have designed solar cells to trap solar energy and convert it to electrical energy energy. A softball is dropped off of the side of a building. Ignore the effects of air resistance. As the ball continues to fall freely, the kinetic energy of the ball 28. An inclined plane reduces the effort force to lift a load by spreading the work out over the length of the plane 29. Increases. Sketch a roller coaster and indicate the position at which a roller car would have the most kinetic energy and where it would have the most potential energy. A roller coaster car would have the maximum kinetic energy at the bottom of the first hill, it would have the maximum potential energy at the top of the first hill. 30. Energy can neither be created A battery converts chemical energy into electrical energy for human use. 24. Name some physical properties of matter: Mass, volume, density, color, solubility, malleability, ductility, hardness 25. Give some examples of physical changes: Melt, dissolve, freeze, evaporate, break, stretch, 26. Name some chemical properties: Flammability, reactivity with acids and bases, rusting, tarnishing, Analyze the data in the following table. Time Distance (seconds) (centimeters) 1 9 2 18 3 4 36 5 45 What is the approximate distance the object has traveled at the end of three seconds? nor destroyed. 23. What is the formula for calculating speed? Speed = distance ÷ time 21. 22. How does an inclined plane help us to do work? 27 centimeters 31. The soft layer of the mantle on which pieces of the lithosphere move is called the asthenosphere. Sixth Grade Science Study Guide 2014-2015 32. The graph below shows the motion of a motorcycle rider. Using data from the graph, a student can conclude that after 25 seconds the rider will have moved a distance of – . Distance vs. Time 40. Draw the beams of a triple beam balance to show 345.6g. 300 grams on the hundreds beam, 40 grams on the tens beam, and 5.6 grams on the ones beam. 41. List some non-renewable energy resources: Fossil fuels (coal, oil, gas), nuclear fuels, 42. There are three beakers with liquids with measurements as shown: 250 meters 33. Venus is the hottest planet. 34. A type of rock that forms when hot, liquid How do the liquids compare in terms of mass, volume, and density? rock hardens is called igneous rock. 35. The lithosphere is made of the crust and the rigid, upper part of the mantle. 36. The longer the inclined plane, the The liquids have the same volumes but different masses, so they have different densities. less effort force required to move a load. 37. What are tectonic plates? Slabs of lithosphere that float on the asthenosphere During an investigation, students added 5 grams of salt to 50 ml of water. The solution was stirred, poured into a Petri dish, and left undisturbed for three days 43. 38. The asteroid belt is located between the orbits of which two planets? Mars and Jupiter 39. What protects the Earth from the temperature extremes of space? Our atmosphere What is left in the Petri dish after Day 3? 5 grams of salt Sixth Grade Science Study Guide 2014-2015 44. The planetary motion modeled by object Y is called revolution. 45. The unit of time based on the motion of object Z is day. 46. Sally finds a block of wood that has a volume of 100cm3. Its mass is 250 grams. What is its density? 2.5 g/cm3 47. What do all living things have in common? They are all made of cells 48. Give the name of each Kingdom: Kingdom 1 - Animalia Kingdom 2 - Plantae Kingdom 3 - Fungi Kingdom 4 - Protista
