All living things breathe, including plants. But plants don’t have lungs and don’t breathe in oxygen. Instead, they breathe in carbon dioxide through holes in their leaves called “stomata.”
Look at stomata under a microscope. Apply a thin layer of clear nail polish on the top and bottom surfaces of a leaf. When the polish dries, apply a piece of clear tape, press, and gently peel and remove. Place the tape on a slide to view under a microscope. Take it further and compare the size and density of stomata from different plants.

Make a Personal Connection
Have a mindful moment outside your classroom. Go to an area where there are plants and find a comfortable position. Close your eyes or lower your gaze as you take slow, deep breaths. As you inhale, think about how you are breathing in oxygen coming from the plants around you. As you exhale, think about how you are breathing out carbon dioxide, something plants need to live. Keep breathing slowly and think about how we need plants to live, and they need us. Take one final breath, stretch your arms outward, and thank the plants for their role in our lives.
