# 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 .
• Materials :

• paper 1/4",1/2" inch ruler
• celery stalk with leaves
• jar,water,different food colors
• student worksheet and pencil.
• # Procedure :
