**# A UNIT ON MEASUREMENT

**Lesson plan 1:** How does water travel in plants?

**Time frame :** About 90 mins.

borrowed from Aylett Nurseries

**Objectives :**

Students to observe how water travels in plants.
Students will see how fast the liquid travels on an hourly basis.
Students will measure the color move using 1/4",1/2",inch .
