Science experiments lesson 15: How a plant drinks and gives out water · Set 249 · 40 questions

What you do (Roots in, leaves out): 1. Water the potted plant well. 2. Slip a clear plastic bag over a leafy branch. 3. Close it gently with a rubber band — not too tight. 4. Leave it in the sun for a few hours, then look for drops.
