Task 3: Tensile stress
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: 10 minutes
The teacher prepares a beaker without a spout or a glass and a dropper for each pupil. For every working group he/she prepares a bottle with a washing up liquid. Pupils prepare at least 20 pieces of smaller coins or paper clips.
Pupils fill the beaker or the glass with cold tap water up to the edge. To make sure the beaker or the glass is completely full, they fill up the last drops of the cold water with a dropper and they do not move the container with the water any more.
Pupils start throwing the coins or paper clips carefully into the container with water. They keep doing this until the water starts flowing over the edge of the container.
