Scientific method

• What is the Scientific Method?

  A structured way to plan experiments
• Why is planning important before conducting an experiment?

  To ensure the experiment's success
• What is the first step of the Scientific Method?

  Observation
• What can an observation in an experiment be based on?

  Something noticed or a given task
• What is the purpose of the research step in the Scientific Method?

  To gather more information about the topic
• What is a hypothesis?

  A prediction about the experiment's outcome
• What should you do after researching your topic?

  Formulate a hypothesis
• What is essential when planning an experiment?

  Clear and easy-to-follow steps
• What should be included in the experiment plan?

  Measurements, quantities, units, and equipment
• Why is it important for the method to be repeatable?

  To allow others to verify the results
• What is the purpose of collecting data in an experiment?

  To analyze and draw conclusions
• What is a common way to present collected data?

  As a table
• What should you consider when collecting data?

  Units and necessary equipment
• What is the analysis step in the Scientific Method?

  Examining data for trends
• How can you present your analysis?

  In the form of a graph
• What does the conclusion explain?

  What was learned from the experiment
• What should you comment on in your conclusion?

  Whether the hypothesis was correct
• What makes a good experiment?

  • Change only one variable
  • Repeat measurements for accuracy
  • Have a control for comparison
  • Present results in clear tables and graphs
• What are the characteristics of a good graph?

  • Suitable title
  • Labeled axes with titles and units
  • Accurate scale
  • Clearly plotted points
• What is an independent variable?

  Something you are changing
• What is a dependent variable?

  Something you are measuring
• What is a control variable?

  Things kept the same for fairness
• What is a method in an experiment?

  Steps for another person to test
• What is the definition of matter?

  Anything that occupies space and has mass
• What are particles in matter responsible for?

  Determining if matter is solid, liquid, or gas
• How are particles arranged in solids?

  Closely packed together
• Why can solids not flow?

  Particles cannot move position
• How are particles arranged in liquids?

  Close together but can move past each other
• What happens to liquids in a container?

  They take the shape of the container
• How are particles arranged in gases?

  Free to move in all directions
• What happens to gases in a container?

  They fill the container completely
• What is melting?

  When solids break apart to form liquids
• What is freezing?

  When liquids form solids by removing heat
• What is boiling?

  When liquids become gases by heating
• What is condensation?

  When gases form liquids by removing heat
• What is the boiling point of water?

  100 °C
• What is evaporation?

  Slow gas formation below boiling point
• What is diffusion?

  Movement from high to low concentration
• How can diffusion be demonstrated in a liquid?

  By adding potassium manganate to water
• How can diffusion be demonstrated in a gas?

  By smelling food from a distance
