  1. CST Prep 4th Grade science vocabulary

  2. An animal that eats plants • herbivore

  3. Groups of living things and the environment they live in • ecosystem

  4. The Earth’s innermost layer; ball shape, mostly nickel and iron • core

  5. The way organisms in ecosystem interact according to what they eat • food chain

  6. The layer just below the Earth’s crust (2nd layer and thickest layer) • mantle

  7. Animals that eat the remains of other animals that have died • scavenger

  8. The measure of the pull of gravity on an object • weight

  9. Movement of seeds from parent plant (wind, water, animals, people) • Seed dispersal

  10. A living thing such as a plant that makes its own food • producer

  11. A hardness scale from softest to hardest (1-10); diamond is hardest • Mohs

  12. Electrical force, strength of power source • voltage

  13. Sprouting of a seed • germinate

  14. A living thing that breaks down organisms for food • decomposer

  15. The space around a magnet where the force of a magnet can act • magnetic field

  16. A mineral’s ability to resist being scratched • hardness

  17. A vibration or shaking of the Earth’s crust • earthquake

  18. An animal that eats (meat) other animals • carnivore

  19. A device for determining direction (north, south, east, west) • compass

  20. A type of rock that forms from completely melted rock • igneous

  21. The Earth’s outer layer (1st layer) • crust

  22. Behavior or body part that helps an animal meet its needs in its environment • adaptation

  23. A diagram that shows how food chains relate and overlap • food web

  24. A circuit that has more than one path for current to flow • parallel circuit

  25. A test where you scrape a piece of rock on a white plate to determine color • streak test

  26. The amount of space an object takes up • volume

  27. A material made up of one or more minerals • rock

  28. A type of rock changed by heat or pressure but not completely melted • metamorphic

  29. A type of rock formed by layers of sediment squeezed together over time • sedimentary

  30. Powderlike male cells that travel from plants to help other plants reproduce • pollen

  31. The smallest unit of an element that has all of the properties of that element • atom

  32. A living thing that eats other living things for energy • consumer

  33. An object that attracts certain materials such as steel, iron, nickel • magnet

  34. Living things that cannot make their own food (mushrooms) • fungi

  35. A material that electrical current can pass through easily • conductor

  36. A device that converts chemical energy into electrical energy • battery

  37. The area where magnetic force is greatest in a magnet • magnetic poles (north, south)

  38. The flow of an electrical charge • current (electrical)

  39. The process of dropping or depositing sediment in a new place • deposition

  40. A temporary magnet made by passing electric current through a wire coiled around an iron bar • electromagnet

  41. The process of moving sediment from one place to another (wind, water, ice) • erosion

  42. An animal that has six-jointed legs • insect

  43. An electric charge that stays on an object (rubbing balloon on wool cloth, shuffling feet on rub) • static electricity

  44. A circuit that has only one path for current • series circuit

  45. A simple test of rocks to determine the hardness of the rock • scratch test

  46. Small organisms that can be seen only with a microscope, many only have one cell • microorganism

  47. A natural solid material with its particles arranged in repeating pattern • mineral

  48. An animal that eats both plants and animals • omnivore

  49. The transfer of pollen from a stamen to a pistil by wind or animals • pollination

  50. To reuse a resource to make something new • recycle
