Practical activity

Topic: Osmosis

Goals: Consolidate in practice the students’ Theoretical knowledge from the Lesson “Osmosis” and allow students learn about how plants absorb water in practice by using colored water and celery stalks.

Practice: The supervisor had put celeries into colored water to demonstrate how the plants would absorb water. After 5 hours, students examined how the plants changed their color. Students cut the bottom of the celery and could see where the water transported up into the celery stem.
