Task 2: Oxygen in the air
Topic: Air
Level: Primary (1.–5. Graders)
Thematic Unit:
Subject: science
Recommended age of pupils: 6–11 years old or older
Time allocated: preparation: 5 minutes, implementation: 5 minutes
The teacher prepares a tea candle for each pair of students, a beaker or a glass, some matches, a soup plate or a bowl. Pupils fill the plate or the bowl with cold tap water, light the tea candle and place it carefully on the water surface. They take a beaker or a glass and close it carefully over the candle. They observe the course of the experiment and write the results in the table in the worksheet. It is important to advise pupils to watch the ongoing experiment until the end – when the last candle goes out and the water surface in the glass rises above the water surface in the plate.
