Print Resource

Abstract

Meteorologists, or weather scientists, use special tools for checking the current temperature and predicting what the temperature might be later in the day or week. At home, we can use a tool called a thermometer to measure the air temperature. By completing this activity, you can better understand that the air temperature changes day-to-day and can learn more about tools to track these changes. This activity can be developed individually by learners that shall be focused on the use of weather tools. Teacher shall maintain a close screw of the work performed by the learners.

Learning Outcomes

The learners will learn how to use daily materials in order to make a bottle thermometer.

  • Organize a teamwork by dividing tasks and roles.
  • Social skills such as leadership, organizational conscience or communication.
  • Critical thinking skills by answering questions before and after building the thermometer.
  • Understanding of air-temperature changes.
  • Management of time and resources in order to fulfil the proposed objectives.
  • Social responsibility and awareness.
  • Ecological competencies.
  • Learn about tools that trach temperature changes.
  • How to work in group.
  • How to understand physics principles.
  • How to create a bottle thermometer.

Other Instructions

In 7 simple steps you will have your bottle thermometer: o Pour the water into the glass bottle. o Pour the rubbing alcohol into the bottle. o Add a few drops of food coloring. Mix by swirling the bottle around, gently. o Insert the straw into the bottle. In the final product, the bottom of the straw should be within the colored water, but should not touch the bottom of the bottle. o Secure the straw with modeling clay at the top of the bottle. Make sure not to cover the top of the straw. o Place your thermometer in the sun and wait for a little while as the liquid rises. o Use the marker to draw a line on the outside of the bottle to show where the top of the liquid is in the straw. Write the date next to that line. Did the liquid in the thermometer rise after being in the sun? How long was the thermometer in the sun before you began to see the liquid rise? Did the liquid rise slowly or quickly?
