      Mixtures: equipment diagrams

      Lesson details

      Learning outcome

      I can create scientific diagrams of common laboratory equipment, showing how they are used together.

      Key learning points

      1. Laboratory apparatus are designed for specific uses and choice of apparatus impacts the quality of results
      2. Equipment can be communicated using 2D drawings/images
      3. Scientific diagrams illustrate how equipment is used together for practical investigations

      Keywords

      • Apparatus - A piece of equipment that is designed for a particular use.

      • Scientific drawing - A 2D representation of a piece of apparatus.

      • Scientific diagram - Use scientific drawings to show how equipment is set up for an investigation.

      Common misconception

      Pupils either put too much or not enough detail into their drawings = muddled representations

      Use the 'less is more' approach, and remind pupils to include labels - **clarity is key**. Allows for less detail and avoids any confusion.

      Teacher tip

      Show pupils equipment not covered in the lesson and challenge them to use the rules to create a representative scientific drawing. Create practical set-ups around the room and challenge pupils to draw the diagrams to represent them.

      A type of mixture

      Q2.
      If you needed to measure the volume of a liquid, which apparatus would you use?

      Balance
      Beaker
      Correct answer: Measuring cylinder
      Ruler

      Q3.
      What unit is commonly used to measure mass in the laboratory?

      Correct Answer: grams, g

      Q4.
      When measuring the volume of a liquid, which unit of measurement is typically used?

      Correct Answer: cm³, cubic centimeters, cm3, cm^3

      Q5.
      How might the presence of impurities in a substance affect the accuracy of measurements taken during an experiment?

      They increase the cost of the experiment
      They make the substance look different
      Correct answer: They can alter the melting and boiling points of the substance

      Q6.
      When measuring the temperature of a liquid, why is it important to ensure the thermometer is not touching the sides or bottom of the container?

      To keep the thermometer clean
      Correct answer: To obtain a more accurate temperature reading of the liquid
      To prevent breaking the thermometer
