Respiratory system and speed dating

INTRODUCTION

Usually when I ask students how they learn most efficiently, they say that they learn more by doing than listening. When studying respiratory system, you can use two activating methods: ”speed dating” and building a model of lungs demonstrating mechanics of breathing.

TOPIC

Human respiratory system.

GOALS

Goals of transversal competences or 21th century skills

  • Thinking and learning to learn
  • Cultural competence, interaction and expression

Goals of biology

  • anatomy of respiratory system
  • gas exchange
  • mechanics of breathing
  • control of ventilation

ACTIVITY/METHOD

  1. ”Speed dating”

Every pupil gets one question about respiratory system. He has some time to find out the answer and memorize it. Then pupils gather in a circle formation, two pupils sitting face to face. They´ll ask the questions from each other. If the answerer don’t know the right answer the asker must complete it. When they have asked both questions they´ll switch the question notes and stand up. When everyone are standing the outer circle changes the places clockwise. You can carry on untill same questions pop out or time runs out.

  1. Building a model of lungs

Build a model of lungs demonstrating the mechanics of breathing. Pupils gets instructions and materials. They have to figure it out and make some observations and conclusions.

MATERIALS

Plastic bottles, rubber bands, small transparent plastic bags, balloons, straws, Blu-Tack or modeling clay and handouts about the model.

USE OF ITC, APPS, WEBSITES

STUDENT ACITIVITY LEVEL

High

NEW IDEAS

Pupils could do the ”Speed date”-questions in advance by themselves. They could take photographs or videos building the model and make a report about it.
