The Scientific Method

  • Problem or Question
    Step 1
  • Hypothesis
    An educated guess about what you think will happen
  • Experiment
    A way to test your hypothesis
  • Gather & Record Data
    Observations of what your discovered
  • Conclusion
    Summary that you create after interpreting your data

Scientific Investigation

  • Observation
    What you notice with your 5 senses
  • Results/ Data
    What you record once you finish an experiment
  • Hypothesis
    An educated guess of what you think will happen
  • Dependent Variable
    The part of the experiment that changes as you change the independent variable
  • Independent Variable
    The part of the experiment that a person changes. What you test.
  • Procedure
    Steps you use to complete an experiment
  • Constant
    The part of the experiment that always stays the same in order for an experiment to be fair
  • Purpose
    Why you are doing the experiment
  • Materials
    All the things you need for the experiment
  • Conclusion
    The results and why the results happened

States of Matter

  • Mass is the amount of space and object takes up
  • A LIQUID has molecules that move freely and bounce off each other
  • Volume is the amount of gas an object has
  • A SOLID has molecules that are very close together and hold on to each other
  • A GAS has molecules that are close together but do not hold onto each other
  • Molecules are the tiny particles that make up matter

Solids

Solids have

  • Definite Shape
  • Definite Volume
  • Neither/ Unknown

Liquids

Liquids have

  • Definite Shape
  • Definite Volume
  • Neither/ Unknown

Gases

Gases have

  • Definite Shape
  • Definite Volume
  • Neither/ Unknown

Matter and Changes in State

  • Weight
    How strongly gravity pulls on an object
  • Buoyancy
    An object's resistance to sinking
  • Mass
    How much matter an object has
  • Volume
    How much space an object takes up
  • Melting point
    The temperature at which a substance melts
  • Boiling point
    The temperature at which a substance boils
  • Freezing point
    The temperature at which a substance freezes
  • Matter
    Anything that takes up space and has mass
  • Element
    Has only 1 ingredient
  • Compound
    Made of 2 or more elements that can ONLY be separated chemically
  • Mixture
    Made of 2 or more elements mixed together, but each elements stays the same and does not change.
