  1. Lesson 2Scientific Tools

  2. Organism(s)Living Things

  3. Microorganism(s)Living thing too small to see with the unaided eye.

  4. Compound Light MicroscopeUses pairs of lenses to form a larger image. Ocular Lens Coarse Adjustment Knob Body Tube Fine Adjustment Knob Revolving Nosepiece Low Power Objective Lens Arm High Power Objective Lens Clips Stage Inclination Knob Diaphragm Base Mirror or Light

  5. Electron MicroscopeUses electrons instead of light to make extremely small objects visible.Can magnify up to 2 million times their actual size!

  6. RulerMeasures length or distance. Meter – Longer lengths Centimeter – Shorter lengths Liter – Measure liquids Milliliter – Measure liquids

  7. Thermometer Measures temperature.

  8. Graduated Cylinders and Beakers Measure Volume.

  9. Pan BalanceMeasures Mass or DensityDensity is mass divided by volume or M D = V

  10. Spring ScaleMeasures Weight.

  11. StopwatchMeasures Time.

  12. Microscopes and Hand LensesMagnify Small Objects

  13. Telescopes and BinocularsReveal details of faraway objects.

  14. Calculators and ComputersOrganize Data and Make Graphs.

  15. Line GraphsVisual display that uses 2 sets of data, like showing how a variable changes over time.

  16. Bar GraphDisplay that shows data as bars of different length.

  17. Circle GraphDisplay that shows data as parts of a whole.

  18. DiagramsPicture or group of pictures that display data.

  19. X – Axis – Horizontal or bottom edge of a graph.Y – Axis – Vertical or left edge of a graph.

  20. A Sieve – Container with mesh or perforated bottom.Used to filter large particles out of a mixture.

  21. Magnets –Attract metal objects

  22. Petri Dish – Growing bacteria

  23. PredictionA guess about what is likely to happen.
