  1. Science GPS ReviewGrade 5

  2. Scientific Inquiry Problem or question Hypothesis Procedure Observations Conclusions

  3. Earth Science Earth’s surface is changed through constructive and destructive processes. If something is constructed, it is built up. If something is destructed, it is destroyed.

  4. Earth Science Deposition (deltas, sand dunes) – the dropping of sediments that have been moved from one place to another

  5. Earth Science Plate tectonics – theory that giant plates of crust are slowly moving across Earth’s surface

  6. Earth Science Earthquakes – violent shaking of the Earth’s crust as built-up energy is released Epicenter – point on Earth’s surface directly above the focus of an earthquake

  7. Earth Science Volcanoes – formed when magma breaks through the surface

  8. Earth Science Seismic Waves – waves of energy sent through Earth’s crust when parts of the crust move suddenly

  9. Faults – cracks in the Earth’s crust where movement takes

  10. Earth Science Ring of Fire – are of many earthquakes and volcanoes along the edge of the Pacific Ocean

  11. Earth Science Surface features caused by destructive processes: • Erosion • Weathering • Impact of organisms • Earthquakes • Volcanoes

  12. Earth Science Erosion – carrying away of sediments by moving water, wind, or ice

  13. Erosion involves removal and transport.

  14. Earth Science Weathering – can be mechanical (rocks broken into smaller pieces called sediment) or chemical (rocks change into other materials or dissolve)

  15. Chemical weathering, takes place when at least some of the rock’s minerals are changed into different substances. Chemical processes include rain, acid etching by plants, oxidizing, and demineralizing by water.

  16. Mechanical weathering, involves physically breaking rocks into fragments without changing the chemical make-up of the minerals within them.There are four main sources of power for mechanical weathering.Gravity, Water, Wind, & WavesOf these, water appears to be the leader in changing the surface.

  17. Earth Science FLOOD CONTROL: dam – a wall across a river that controls the flow of river water

  18. Earth Science FLOOD CONTROL: levee – a wall along the banks of a river that serves to keep the water behind it

  19. Earth Science FLOOD CONTROL: storm drain – a system of pipes or channels that carry away storm water)

  20. Earth Science BEACH RECLAMATION: (Georgia coastal islands) – beach erosion is caused by dredging (deepening bodies of water), rivers changing direction, and rising ocean levels – beaches can be rebuilt through nourishment (adding more sand), building sea walls to stop erosion

  21. Earth Science BEACH RECLAMATION:

  22. Physical Science The mass of an object is equal to the sum of its parts. This clay ball has a certain mass. If I break it into pieces, the mass of the pieces will be the same as the entire ball.

  23. Physical Science Physical properties of matter: color, shape, texture, luster, density

  24. Physical Science Chemical properties of matter (can only be seen when a chemical change has happened) – air can cause rust, water, heat

  25. Physical Science Physical Changes Do not result in a new material Ex. Folding paper Ex. Water changing state (through changes in temperature)

  26. Physical Science Chemical Changes result in a new material being created. Ex. Oxidation from rusting of metal or browning of fruit Ex. Combining vinegar and baking soda to produce a gas Ex. Decaying material in a compost pile

  27. Physical Science When a chemical change occurs, there may also be: • A change in temperature • A gas being released • A change in acidity • A change in measurement • A change in physical attributes (color, texture, odor)

  28. Physical Science Static electricity – electric charge built up on material

  29. Physical Science Electric current – a continuous flow of electric charges

  30. Physical Science Complete circuit – the pathway that an electric current follows

  31. Physical Science Insulators (stop electric flow) and conductors (allow electricity to flow)

  32. Physical Science Parallel circuit – more than one pathway for the electricity to follow

  33. Physical Science Series circuit – only one pathway for the electricity to follow

  34. Physical Science Bar magnets (attract some metals) and electromagnet (a strong temporary magnet)

  35. Life Science Classify organisms into five kingdoms (animal, plant, fungi, protists, bacteria)

  36. Do you know that there are FIVE Kingdoms of living things? Moneran Protist Fungus Plant Animal Many- celled Many- celled One-celled with no membrane around the nucleus One-celled Most are many- celled

  37. Life Science Animals can be sorted into groups (vertebrate and invertebrates) Vertebrates can be sorted into groups (fish, amphibian, reptile, bird, mammal)

  38. Animals Vertebrates Invertebrates

  39. Mammals Vertebrates • Have body hair or fur • Have mammary glands that produce milk • Warm blooded

  40. Fish Vertebrates • Live in water • Breathe with gills • Streamlined bodies • Have cartilage or bony skeleton • Cold blooded • Mostly lay eggs

  41. Reptiles Vertebrates • Have dry, scaly skins • Egg laying • Breathe with lungs • Cold blooded

  42. Amphibians Vertebrates • Moist skin • Lay their eggs in water • Larvae have gills and live in water • Adults have lungs and live on land • Cold blooded

  43. Birds Vertebrates • Have feathers and wings • Lay eggs with hard shells • Breathe with lungs • Warm blooded

  44. Animals Invertebrates Vertebrates Cnidarians Mammals Flatworms Fish True worms Reptiles Molluscs Amphibians Echinoderms Birds Arthropods

  45. Life Science Plants can be sorted into groups – Vascular (have tubes) and nonvascular (absorb water through cells angiosperms (vascular plant that produces seeds from flowers), gymnosperm (vascular plant that produces weeds, but not flowers or fruit)

  46. Life Science Parts of an animal cell (membrane, cytoplasm – jelly-like substance, nucleus – the brain)

  47. Life Science Parts of a plant cell (membrane, cell wall, cytoplasm – jelly-like substance, nucleus – the brain, chloroplasts – make food and provide green color) Functions of cell parts

  48. Life Science Functions of cell parts
