Grades: K-5

Learning Goals:

  • Identify the lungs as the organ responsible for breathing.
  • Explain how humans breathe.
  • Describe how to take care of their lungs.
  • Identify water as a necessity for the body to function.
  • Learn how to make an “Agua Fresca” drink.


One recipe makes approximately 10-12 servings (1/2 cup each). Determine amounts needed based on number of kids

  • Watermelon (sliced into triangular sections with skin, then peeled and cubed by students)
  • 3 cups Water
  • 2-3 teaspoons lime juice
  • 1 tablespoon honey
  • Blender
  • Chef’s knife
  • Plastic knives for students
  • Paper plates
  • Strainer
  • Pitcher
  • Large Spoon
  • Cups


  • Inhale: to breathe in air
  • Exhale: to breathe out air
  • Hydrated: the body has enough water or moisture needed to function


  1. Aquaman is a unique superhero who learned many of his skills through training and scientific secrets. He has many different powers. Aquaman has superhuman strength and stamina, which means he can do something active for a long time without getting tired. Aquaman can swim extremely fast, breathe underwater, and can see in the dark. He can even communicate to marine animals and tell them what to do by simply using his mind.
  2. Aquaman’s powers help him to be strong and successful underwater. As humans, we can only be under water for a short amount of time because our bodies need oxygen from the air to survive. You have two lungs in your chest that allow you to inhale, which means breathe in air, and exhale, which means breathe out air. You can feel your lungs working by putting your hand on your chest, inhaling, and then exhaling. Did you feel your chest get bigger as your lungs took in air, then get small again when you exhaled?
  3. Each time you take a breath, the air travels down your windpipe to your lungs, which then carries oxygen to the rest of the body. Then when you exhale, the air you breathe out carries waste that your body doesn’t need. Besides simply breathing, your lungs also allow you to laugh, talk, sing, shout, and more!
  4. Since your lungs have such an important job, keeping them healthy is a smart idea. Some ways to keep your lungs healthy are by breathing in clean air (no smoke or pollution) and by exercising. As you exercise, your lungs become stronger and better at taking in air to give your body the oxygen it needs.
  5. Aquaman doesn’t need to breathe in air the way we do. Instead, his body depends on water. You don’t have the ability to breathe underwater like Aquaman, but every part of your body also depends on water and works best if you are hydrated. Hydrated means that your body has enough water or moisture to work. You wouldn’t be able to talk or sing if your throat were too dry!
  6. Today we will make Agua Fresca, which is a term in Spanish that means a cool watery drink, sometimes with fruits or edible flowers in it. This drink will help our bodies stay hydrated on a hot day. The Agua Fresca we will make includes a fruit: watermelon. The name tells us one reason why this fruit is so good for our bodies. Can you guess what part of the name ‘watermelon’ tells us is good about it? (WATER) Watermelon is so juicy and helps quench our thirst and keep us hydrated because it’s made of 92% water!

Your kids will make their own Aquaman’s Watermelon Agua Fresca. One recipe makes approximately 10-12 servings (1/2 cup each).

  • Invite the children to wash their hands. Ask the children to help set up their cooking area. All fruit should be washed.
  • Place the watermelon on a cutting board and cut it into sections to reveal the inside of the fruit. Demonstrate how much juice flows from the watermelon just from cutting it. Cut into slices.
  • Pass out watermelon slices. Demonstrate how to cut fruit away from peel and then cut into cubes. Ask the children to describe the texture of the watermelon. It is almost like a sponge that has soaked up a lot of water.
  • Put the watermelon cubes into the blender.
  • Measure out honey and add to blender.
  • Measure lime juice and add to blender.
  • Measure out half of water and add to blender.
  • Blend the water and fruit mixture. Ask the children to observe how the water/juice levels change as the watermelon is blended because of how much liquid it contains.
  • Pour contents of blender through a strainer into a pitcher. Add remaining water and stir until well combined. Add ice or put in the fridge before serving if desired/time permits.
  • Pour the agua fresca into the cups. Ask children to try the drink and to tell you if they feel more hydrated.

What I Learned/Assessment:

  • What part of your body allows you to breathe in air?
  • What does it mean to inhale and exhale?
  • What can you do to keep your lungs healthy?
  • What does your body need you to drink in order for your lungs and other organs to work?
  • Why does a drink with watermelon keep us hydrated?
