  1. 3. What stays the same in an experiment.
  2. 5. A tool that is used to add/remove a small amount of liquid in an experiment.Pipettes measure liquid in 1-2 ml.
  3. 7. Beam Balance A tool used to measure the mass of an object.(How much matter is inside of it.)
  4. 8. Using resources wisely.Reducing,reusing,and recycling where possible.
  5. 9. A summary of what was observed during an experiment.A good conclusion tells if your hypothesis was correct,what happened, describes what you learned and what you could improve if the same test was repeated.
  6. 11. A small, enclosed container that holds a small ecosystem which includes living organisms, their food source, and the nonliving elements they require to survive.(O2/CO2/H2O,ect...)
  7. 13. A tool used to measure the volume of a substance Graduated Cylinders record volume with more exact measurement than a beaker.(Ex.You can measure exactly 13 ml with a Graduated Cylinder,while a beaker measures larger amounts like 50,or 100 ml.)
  8. 17. The thing that you change in an experiment.(You can only have one independent variable in an experiment.)
  9. 19. A tool that is used to determine direction by identifying magnetic north.
  10. 20. A container that is used to hold and measure the volume of a substance(not very exact,measures in units of 50.)

  1. 1. Step by step directions that explain what actions need to be taken to complete an experiment.
  2. 2. Weaknesses that a model has that makes it not exactly the same as the real item.(Ex.Although a ball can be the same shape and color as the sun, it is not the same temperature.)
  3. 4. What changes in an experiment due to you changing something else. What you measure in an experiment.
  4. 6. Measurements and recorded observations that take place during an experiment(charts,and graphs.)
  5. 10. Scale A tool that is used to measure the pull of gravity on an object.(Weight)
  6. 12. An educated guess about what will happen in an experiment.Written as an if....then....because....statement.
  7. 14. Facts that are observable and measurable.
  8. 15. Using observations combined with prior knowledge to describe what possibly happened.
  9. 16. A tool that is used to magnify an object so that it appears larger than it actually is.
  10. 18. Enclosed container that holds a small water ecosystem for fish and other aquatic animals.
