Every animal needs water — but they don't all get it the same way!
📋 NGSS Standard: K-LS1-1 — Use observations to describe patterns of what plants and animals (including humans) need to survive.
🎯 Learning Objective
Students will DESCRIBE at least 3 different ways animals get water and MATCH each method to a specific animal example.
💡 The Big Idea
All animals need water to survive — it's one of their four basic needs (remember from Lesson 1!). But not every animal sips from a puddle. Animals have amazing and surprising ways to get the water they need. Dogs lap, frogs soak, and desert tortoises munch on juicy cactus. Today, you'll discover all three methods — and try them yourself!
absorb = to soak up | moisture = tiny amounts of water | hydration = getting enough water | adaptation = a body trick for surviving in tough places | lap = to scoop water with the tongue | permeable = lets water pass through
📦 Materials
🏠 All Household Items
Shallow bowls or plates (one per station)
Water
Food coloring (for Station 2)
Paper towels (for Station 2)
Juicy fruit — orange slices, watermelon chunks, or grapes (for Station 3)
Towel for cleanup (you'll need it for Station 1! 😄)
🔬 The Science
Water is one of the four basic things every animal needs to survive. But animals have evolved different adaptations — clever strategies — to get the water their bodies need:
Drinking directly — like dogs and cats, who lap water from a bowl or stream
Absorbing through skin — like frogs, who can soak up water through their moist skin without even opening their mouths!
Eating wet food — like desert animals that munch on juicy cactus or fruit to get the moisture they need
Each strategy works best in different environments. Desert animals, for example, can't rely on puddles — so they've evolved to get water from their food instead.
💡 Fun facts to share: Koalas rarely drink water — they get almost all their moisture from eucalyptus leaves! And some desert beetles collect fog on their backs and let it roll down to their mouths. Nature is wild.
🧪 Drinking Stations Activity
Set up three stations and visit each one. Compare which method gets the most water the fastest!
🐕
Station 1 — Lap It Up!
Like a dog or cat: Fill a shallow bowl with water. Try lapping water from it using only your tongue — no hands allowed!
Spoiler: It's surprisingly hard for humans. Dogs curl their tongue forward like a ladle scooping forward to scoop water up — try it! (Cats actually curl their tongue backward, which is different. Dogs go forward!)
🧠 Think about it: Why would lapping work better than just putting your face in the bowl?
🐸
Station 2 — Soak It Up!
Like a frog: Add food coloring to water in a shallow plate so you can see it clearly. Lay a dry paper towel flat on top of the colored water. Watch what happens!
Frogs absorb water directly through their skin — they don't even need to drink! Their skin is specially designed to soak up moisture from the ground, puddles, or damp leaves.
🧠 Think about it: Did the paper towel absorb water slowly or quickly? Where do you think frogs like to sit?
🌵
Station 3 — Eat It!
Like a desert tortoise: Bite into a juicy piece of fruit — an orange slice, watermelon chunk, or grape. Notice how much liquid is inside!
Many desert animals can't find puddles or streams, so they get their water from the food they eat. Desert tortoises eat juicy cactus pads. Some animals eat insects that are full of moisture.
🧠 Think about it: If you lived in a desert with no puddles, which food would give you the most water?
📊 Compare Results!
After visiting all three stations, discuss:
Which method got the most water the fastest?
Which was the most surprising?
Which would work best if you lived in a rainy forest? What about a hot, dry desert?
💬 Discussion Questions
🗣️ Question 1: The Camel Puzzle
"A camel can go a long time without drinking. Where do you think it stores extra water?"
Most people think camels store water in their humps — but actually, their humps store fat! Camels can go without drinking for up to two weeks in cool weather (less time in heat) because their body is extremely efficient at conserving water — not because they store it. They can drink a huge amount at once (up to 30 gallons!) and then use it very efficiently. Their kidneys and sweat glands are specially adapted to waste as little water as possible.
🗣️ Question 2: Desert Life
"Why do you think animals that live in the desert have to get water from food instead of puddles?"
Deserts get very little rain, so there aren't many puddles or streams. Animals that live there have evolved clever ways to get water from their food — like eating juicy cactus or insects full of moisture. It's called an adaptation — a special trick that helps them survive in a tough environment!
🚀 Extensions
🌿 Koala Research: Look up photos of koalas eating eucalyptus leaves. They almost never drink water — all their moisture comes from leaves! Can you find another animal like this?
🪲 Fog Beetle: Draw a picture of a Namib desert beetle collecting fog on its back. Research how its bumpy shell is designed to catch tiny water droplets from morning fog.
📚 Read Aloud:"What Do Animals Need?" or any National Geographic Kids book about desert animals
🏜️ Desert vs. Rainforest: Draw two habitats side by side. For each one, name 2 animals and show how each gets water.
🧪 Absorption Race: Test different materials — paper towel vs. cloth vs. plastic wrap. Which absorbs water the fastest? Why do you think frogs have moist, permeable skin?
👩🏫 Parent/Teacher Notes
All household materials: Fruit from the kitchen, bowls, paper towels, food coloring — no special supplies needed. Substitutions are fine — the specific fruit doesn't matter, just something juicy (wet food category). An orange, grape, watermelon chunk, cucumber, or even a slice of tomato all work.
Station 1 warning (in the best way): The lapping activity is hilarious and kids absolutely love it. Have a towel ready — things will get wet. Let them laugh! That's the fun.
Connect to Lesson 1: Reinforce that water is one of the 4 basic animal needs from earlier in the unit. This lesson shows the how, not just the what.
Fun fact to share: Koalas get almost all their moisture from eucalyptus leaves and rarely drink water. Some desert beetles collect fog on their backs and let it roll down to their mouths — nature's own water collector!
Vocab to reinforce:absorb (to soak up), moisture (tiny amounts of water), hydration (getting enough water), desert adaptation (a special body trick for surviving in dry places)
Assessment: Can the child name at least two different ways animals get water? Can they explain why desert animals eat wet food instead of drinking from puddles? That's success.

How It Gets Water
Science Note
🐕 Dog
🫧 Drinks from puddles
Dogs lap water by curling their tongue forward (like a ladle scooping forward) to scoop it up — very efficient! Note: cats curl backward; dogs curl forward.
🐸 Frog
💦 Absorbs through skin
Frogs have permeable skin designed to absorb moisture. They often sit in damp soil or shallow water to rehydrate.
🐢 Desert Tortoise
🌵 Eats juicy cactus
Desert tortoises eat cactus pads, wildflowers, and other juicy desert plants to get moisture. They can store water in their bladder!
💡 Discussion Answer Notes
Q1 — Camel's hump:Camels store FAT in their humps, not water! Their amazing bodies are extremely efficient at conserving water. They can drink up to 30 gallons at a time and use it very slowly. Accept any answer that engages with the question — the real learning is in the surprise that it's fat, not water!
Q2 — Desert animals eating wet food:Deserts get very little rain — sometimes less than 1 inch per year! With no puddles or streams, animals have adapted to get water from juicy plants, insects, and other food sources. Key word to reinforce: adaptation. Look for answers that show understanding of scarcity (not much rain = not much water to drink).
✅ What Success Looks Like
Child can name at least two different ways animals get water (e.g., drinking and absorbing).
Child can explain why desert animals eat wet food instead of drinking from puddles (no rain, no puddles).
Child correctly matches all three animals on the worksheet.
Bonus: Child uses a vocabulary word like absorb or adaptation in their explanation.
🐸 Bonus Fun Facts (For Curious Kids!)
Koalas almost never drink water — they get nearly all their moisture from eucalyptus leaves.
Namib desert beetles collect fog on their bumpy backs in the early morning and let tiny droplets roll down to their mouths. A built-in fog collector!
Thorny devil lizards in Australia have tiny channels on their skin that funnel rainwater and morning dew straight to their mouths.
Kangaroo rats in North American deserts almost never drink water — they get all their moisture from dry seeds through a metabolic process.
