Spring has surely sprung when you see new leaves on the trees, but how do plants breathe? Biological science can be absolutely hands-on and engaging for young learners. All you need to do is head outside and grab a few leaves to get started.  Learn all about how plants breathe and take learning outdoors with this fun and simple spring STEM activity.

HOW DO PLANTS BREATHE?

Let’s head outside and learn how leaves breath in this simple spring stem activity. Head outdoors, grab some fresh leaves and be prepared to see some fun breathing from leaves!

This simple spring activity asks the question: How do plants breathe?

YOU WILL NEED:

  • Shallow glass bowl or container
  • Fresh leaves (actually removed from the tree)
  • Lukewarm water (room temperature will work if necessary)
  • Patience, this leaf science activity will take a few hours of magic before you can start to observe anything happening.
  • Magnifying glass (optional)

HOW PLANTS BREATHE ACTIVITY SET UP:

STEP 1:  Cut a green leaf off of a plant or tree. You will need fresh leaves and not leaves picked off the ground.

STEP 2: Add lukewarm water to a shallow glass container or bowl. 

STEP 3: Place a single layer of leaves inside the water, submerging them just below the surface with a small heavy item. Place the bowl in the sun.

STEP 4: Wait for 2 to 3 hours.

STEP 5: Watch as little air bubbles form on the top of the leaves.  What is happening?  If have difficulty seeing the bubbles, use a small magnifying glass!

PLANT RESPIRATION IN THE CLASSROOM

This simple how plants breathe activity is perfect for science learning in the classroom or at home. My best tip is this! Set this activity up at the beginning of the day and check in to see plant respiration in action right before lunch OR start it after lunch and observe what happens before your class leaves for the day. Remember, it will take a few hours before you’ll be able to see respiration in action!

Variation: If possible gather a few different specimens of leaves and observe any differences during the process!  Different types of broad tree or plant leaves will be easiest to observe.

HOW DOES A PLANT BREATHE?

The simple science behind this how plants breathe activity is plant respiration!

Oxygen is an important gas for animal life on earth!  Without it, we can’t breathe!  Plants help us breathe by taking in carbon dioxide (for photosynthesis) and letting out oxygen through their leaves. This process is called plant respiration.

WHY DO PLANTS NEED SUNLIGHT?

The sun is key to this science activity!  The leaf uses the sunlight during photosynthesis, which is where the plant converts the light energy into chemical energy or food for the plant. During photosynthesis, the leaf gets rid of what it doesn’t need which is extra oxygen and water.

Check out our photosynthesis worksheet for kids!

Photosynthesis is what allows us to see the bubbles! All the extra oxygen the plant releases during photosynthesis can be seen in the form of bubbles of gas which rise to the surface in the water.  The bubbles you see in the water is plant respiration in action!

Learn about why plants are called producers in the food chain!
