Task 3: The speed of evaporation of commonly available liquids
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 various liquids, which pupils encounter on a daily basis, and the same number of slides and droppers. Pupils make a single drop of the liquids on the slides or unabsorbent mat by using the droppers and watch the process. Pupils should already be able to estimate precisely, what the order of the vaporization of the given solution will be, and they write it in the attached table.
