Week 4

Measurement is a way of describing how big or small something is. It is important in science because we need to be able to measure things accurately in order to understand the world around us. Let’s look at some examples to help understand measurement:

  1. Length: Length is how long something is. We use units like meters (m) and centimeters (cm) to measure length. For example, the length of a pencil might be 15 cm, while the length of a classroom might be 10 m.
  2. Mass: Mass is how heavy something is. We use units like grams (g) and kilograms (kg) to measure mass. For example, a small apple might have a mass of 100 g, while a bag of potatoes might have a mass of 2 kg.
  3. Volume: Volume is how much space something takes up. We use units like milliLitres (ml) and Litres (L) to measure volume. For example, a glass of water might have a volume of 250 ml, while a swimming pool might have a volume of 100,000 L.
  4. Time: Time is how long something takes. We use units like seconds (s), minutes (min), and hours (h) to measure time. For example, it might take 30 seconds to run across a field, while it might take 1 hour to bake a cake.

By learning how to measure things, we can better understand the world around us and make important observations and predictions in science.

Measurement tools or devices

Here are 5 measurement tools or devices commonly used in science and engineering:

  1. Ruler or tape measure: A ruler or tape measure is used to measure length or distance. It typically consists of a long, flat piece of material with markings in units of measurement such as inches or centimeters.
  2. Balance or scale: A balance or scale is used to measure mass or weight. It typically consists of a platform on which an object is placed, and a beam or digital display that shows the weight of the object in units such as grams or kilograms.
  3. Thermometer: A thermometer is used to measure temperature. It typically consists of a glass or plastic tube filled with a liquid, such as mercury or alcohol, that expands or contracts as the temperature changes, and a scale that shows the temperature in units such as degrees Celsius or Fahrenheit.
  4. Stopwatch or timer: A stopwatch or timer is used to measure time. It typically consists of a digital or mechanical display that shows elapsed time in units such as seconds or minutes.
  5. Graduated cylinder or beaker: A graduated cylinder or beaker is used to measure volume. It typically consists of a container with markings in units of measurement such as milliLitres or Litres, which allows for accurate measurement of the volume of a liquid.
