Lesson: How is water transported in plants?
In this lesson we are going to explore the journey of water to all parts of the plant and how it evaporates through the leaves. We will identify that this process is called TRANSPIRATION. Our investigation will explore the rate of transpiration in plants and which factors can affect it. Your teacher will tell you which scientific skill, either Planning or Presenting and analysing data or Evaluation, to focus on during this lesson.
