Sun & Ocean Interactions Activity: 8 Hands-On Stations for Teaching the Water Cycle and Weather (TEKS 5.10A)

Chris Kesler · 8 min read

Pour ice water into a clear plastic cup, set it on the table, and within minutes the outside of the cup is dripping. Where did that water come from? Not the cup. The water that's beading up on the outside came out of the AIR. It was invisible water vapor a minute ago. Now it's a droplet you can wipe with your finger. The same process happens in the atmosphere every day on a planetary scale. That's the water cycle.

That's TEKS 5.10A. It asks 5th graders to investigate and explain how the Sun and ocean interact in the water cycle and in weather patterns. They have to use "evaporation," "condensation," "precipitation," "water vapor," and "water cycle" with meaning. They have to explain why the Sun powers the whole thing.

The Sun & Ocean Interactions Station Lab for TEKS 5.10A puts two cups on every group's table — one hot, one ice cold — and asks them to feel the warm humid air rising off the hot cup (evaporation) and watch droplets bead up on the cold cup (condensation). Then they look at a U.S. precipitation map showing Forks, Washington getting 119 inches a year and Phoenix, Arizona getting 8 inches, and they explain WHY. By the end, they can trace a single water droplet from the ocean, into the sky, into a cloud, and back to the ground.

8 hands-on stations for teaching the Sun, the ocean, and the water cycle

A station lab is a student-led activity where small groups rotate through 8 stations (plus a 9th challenge station for early finishers) at their own pace during one to two class periods. You become a facilitator instead of a lecturer. You walk around, spot-check, and break misconceptions while kids work through the rotation.

The Sun & Ocean Interactions Station Lab has four input stations (where students take in new information on evaporation, condensation, precipitation, and the water cycle) and four output stations (where they show what they learned). Here's what's at each one.

4 input stations: how students learn the water cycle

🎬 Watch It! —

A short YouTube video introduces the water cycle from the source (the Sun) all the way through evaporation, condensation, and precipitation. Three questions on the answer sheet check whether students caught the big ideas: what the repeating evaporation-condensation-precipitation process is called, what state of matter water is in when it evaporates (gas), and what water vapor condenses into when it rises into the cold atmosphere (clouds). The video gives kids a moving picture of the cycle before they meet the vocabulary on paper.

📖 Read It! —

A one-page passage called "Water Cycle" opens with a relatable hook: where did the water in your water bottle come from? It might have been frozen in a glacier or rained somewhere else first. The passage walks through 97 percent of Earth's water being in oceans, the Sun heating that water and turning it into water vapor (evaporation), the vapor rising and cooling into clouds (condensation), and the clouds releasing rain, snow, and hail (precipitation). Vocabulary is bolded throughout (water vapor, evaporation, condensation, precipitation, water cycle). Three multiple-choice questions follow, plus the vocabulary section. Comes in two reading levels (Dependent and Modified) plus a Spanish version.

🔬 Explore It! —

This is the station where the water cycle stops being a diagram and starts being something kids can FEEL. Each group has two cups: Cup A is full of hot water, Cup B is full of ice water. Students carefully hold their hand above Cup A and feel the warm humid air rising (that's evaporation happening in real time). Then they look at the outside of Cup B and notice droplets beading up out of nothing (that's condensation pulling water vapor out of the air). Five questions tie it together: what does the air over the hot cup feel like, where does the energy for evaporation in nature come from (the Sun), what do you notice on the sides of Cup B, and how does this relate to clouds and precipitation. A water-cycle diagram with labeled evaporation, condensation, precipitation, transpiration, ocean, stream, river, lake, and groundwater is included.

💻 Research It! —

Twelve reference cards walk through evaporation (with a diagram of water vapor rising from oceans, lakes, and a tree), condensation (with photos of clouds), precipitation (with rain, snow, and hail photos), and the full water cycle in one labeled diagram. The standout card is a U.S. precipitation map paired with a data table: Denver gets 15.5 inches per year, Forks, WA gets 119.72 inches, Miami gets 61.9 inches, New Orleans gets 63.5 inches, Phoenix gets 8.3 inches, Detroit gets 30.97 inches. Four questions tie it together: what the Sun provides, what the Sun's energy does to liquid water, what kind of air condenses water vapor back to liquid, and what the rainiest areas in the U.S. have in common (proximity to oceans and big bodies of water). The geography piece makes the lab feel relevant to wherever the student lives.

4 output stations: how students show what they learned

📋 Organize It! —

A two-part card sort. First, students match five vocabulary terms (EVAPORATION, CONDENSATION, PRECIPITATION, WATER VAPOR, WATER CYCLE) to their definitions. Then they match five image cards (A: arrows rising from a lake, B: a sky full of clouds, C: rain falling from a storm cloud with lightning, D: water vapor rising as visible steam, E: a labeled water cycle diagram) to the matching vocabulary word. The picture-to-word match is the part where kids who memorized definitions but didn't really understand them get exposed. A sky full of clouds is condensation. A storm with rain is precipitation. The visible steam image trips up almost every group because they call it evaporation when it's technically condensation (the steam is visible because the vapor has already condensed back into tiny droplets).

🎨 Illustrate It! —

Students draw a quick sketch showing the path a water droplet could take through the water cycle, including as it becomes part of our weather. Four things have to be labeled: evaporation, condensation, precipitation, and weather. The droplet-journey framing turns abstract vocabulary into a story. By the time a kid has drawn a droplet starting in the ocean, evaporating up to a cloud, condensing into a cloud, falling as rain, and running off as a stream, they've internalized the full cycle without writing a single sentence.

✍️ Write It! —

Three open-ended questions in complete sentences. First, why are the Sun AND the ocean both important to the water cycle (the Sun provides the energy, the ocean provides 97 percent of the water). Second, how does the water cycle help create weather on Earth. Third, what is the difference between evaporation, condensation, and precipitation. The Sun-and-ocean question is the title question of the standard and the one most directly testing TEKS 5.10A. The weather question is the bridge between the water cycle and the kid's lived experience of rainy days and snowstorms.

📝 Assess It! —

Three multiple-choice questions plus a fill-in-the-paragraph that uses the five Read It! vocabulary words (evaporation, condensation, precipitation, water vapor, water cycle). The multiple choice covers what rain, snow, and hail are examples of (precipitation), what it's called when water turns from a liquid to a gas (evaporation), and what the continuous movement of water through atmosphere, land, oceans, and living organisms is called (water cycle). The paragraph traces water from the ocean, through evaporation, condensation, and precipitation, and back. If you're grading the lab, this is the easiest station to grade.

Bonus Challenge It! station for early finishers

🏆 Challenge It! —

Four optional extensions: write a song or rap (at least two verses and a chorus) to help remember the water cycle and how it affects weather; write a creative story from the point of view of a water droplet going on an adventure through the cycle; create a colorful poster that illustrates the steps of the water cycle and how each step affects weather; or build a crossword puzzle using at least 10 vocabulary words from the lab (paper or via the Discovery Education puzzle maker, with an answer key). Requires teacher approval before they start.

How this fits into a complete Sun & Ocean Interactions unit

This Station Lab is the Explore day of our full Sun & Ocean Interactions Complete 5E Lesson for TEKS 5.10A. The complete two-week unit follows the 5E method of instruction and includes an Engage hook, the Sun & Ocean Interactions Station Lab for Explore, PowerPoint slides and interactive notebook pages for Explain, student choice projects to Elaborate, and an Evaluate assessment.

Most 5th-grade teachers grab the full 5E because the Station Lab lands hardest with the days around it. But if you just need a strong hands-on day on the water cycle and how the Sun powers it, the Station Lab on its own does the job.

Materials needed to teach Sun and ocean interactions

Materials beyond what's in the download:

Two clear plastic cups per group for the Explore It! station — one for hot water (Cup A) and one for ice water (Cup B). Clear cups make the condensation droplets much easier to see.
Hot water for Cup A (a teacher's electric kettle or a microwave-heated pitcher works; the water doesn't need to be boiling, just hot enough to feel through the cup).
Ice water for Cup B (just ice and tap water from the classroom sink, mixed about 5 minutes before kids hit the station).
Towels or paper towels for the inevitable spill at the Explore It! station.
Colored pencils or markers for the Illustrate It! station, especially blue for water and gray for clouds.
Pencils and the printed answer sheets (included)
A device with internet for the Watch It! station

Common student misconceptions this lab fixes

"Clouds are made of cotton or smoke or something else, not actual water."
5th graders look up at fluffy white clouds and call them "sky cotton" or compare them to smoke. The Explore It! station ends that idea in 30 seconds. When students hold their hand over the hot cup, they feel warm humid air rising. When they look at the cold cup, they see actual water droplets forming on the OUTSIDE of the cup — water that came from the air. The Read It! passage names it: "In the atmosphere, water vapor can condense in large enough quantities to form clouds." Clouds are condensation. The Research It! cloud photos confirm it. By the end, kids know that clouds are just billions of tiny water droplets suspended in the air, exactly like the droplets on the cold cup but way higher up.
"The Sun dries things up, but that's where the water ends. It doesn't go anywhere."
5th graders think evaporation is the end of the story: the puddle dries up, the water vanishes, end. The Read It! passage takes this on directly with a parenthetical reassurance: "Don't worry! Even though ocean water is constantly evaporating, the oceans aren't slowly disappearing. Other processes return the water to the oceans." The Explore It! station shows them where the water goes: it becomes water vapor (a gas) in the air. The Research It! water cycle diagram shows the full path — evaporation up, condensation into clouds, precipitation back down. The Write It! Sun-and-ocean question forces them to put it in their own words. By the end, evaporation is the START of a cycle, not the end of a story.
"It rains when the clouds bump into each other."
Cloud-collision is one of the most stubborn 5th-grade explanations for rain. It sounds reasonable. It's wrong. The Research It! card 5 explains the real mechanism: "As clouds form, they may eventually become saturated or have too much liquid water to hold. The clouds release this liquid in the form of precipitation." Clouds rain when they hold more water than the air can support, not when they smack into each other. The Explore It! Cup B demonstration is the perfect analogy: condensation builds up on the cup until a droplet gets too heavy and runs down the side. That's exactly what happens in a cloud, just on a planetary scale. The Assess It! paragraph asks them to use the word "precipitation" in a sentence about clouds releasing water back to Earth.

Tips for teaching Sun and ocean interactions in your 5th grade classroom

Two things make this lab go smoother the first time:

1. Refill the cups between rotations.

Cup A (hot water) cools off after a couple of rotations and stops producing the warm humid feeling kids need to notice. Cup B (ice water) loses its outside droplets once it warms up. Have a thermos of hot water and a small cooler of ice water near the station so you can top off the cups between groups. Two minutes of prep saves the demonstration. If you forget, the third and fourth groups will still get the idea from the diagram, but they won't get the visceral "oh, I can feel it" moment.

2. Talk through the visible-steam misconception before they start.

If a kid sees steam coming off the hot cup and calls it evaporation, they're half right. The water vapor itself is invisible (true evaporation), but what they see as visible "steam" is actually that vapor already starting to condense back into tiny droplets in the cooler air. This catches every group at the Organize It! station because image D is a black background with white visible steam. Mention this once before the lab starts and you'll save yourself five explanations during the rotation.

Frequently asked questions

What does TEKS 5.10A cover?

Texas TEKS 5.10A asks 5th grade students to investigate and explain how the Sun and ocean interact in the water cycle and in weather patterns. Students should be able to use evaporation, condensation, precipitation, water vapor, and water cycle correctly; explain that the Sun is the energy source for the whole cycle and that the ocean holds about 97 percent of Earth's water; and connect the water cycle to the rain, snow, and storms that make up weather.

What's the difference between evaporation, condensation, and precipitation?

Evaporation is when liquid water gains energy from the Sun and turns into water vapor (a gas). Condensation is the reverse — water vapor cools and turns back into a liquid (forming droplets or clouds). Precipitation is when those droplets get heavy enough to fall back to Earth as rain, snow, sleet, or hail. The Explore It! hot-cup-and-cold-cup demo lets kids feel and see the first two in real time.

How long does this Sun & Ocean Interactions activity take?

One to two class periods (45 to 110 minutes total). The Explore It! cup station takes the longest the first time through, so plan for two periods the first time you run a station lab. Once your class has the rotation routine down, most groups can finish all 8 stations in one period.

Do I really need hot AND cold water?

Yes, and that's the whole point. The hot cup demonstrates evaporation (you can feel the warm humid air). The cold cup demonstrates condensation (water beads up on the outside). With just one or the other, kids only see half the cycle. Both together is what makes the demo work. A thermos of hot tap water and a pitcher of ice water is all you need.

Can I use this in a 1:1 digital classroom?

Yes. The full digital version (PowerPoint or Google Slides) works in 1:1 classrooms and Google Classroom. Students drag vocabulary and image cards at the Organize It! station and type their answers. The Explore It! hot-and-cold-cup demonstration is harder to digitize, so if you're fully remote, sub in a short video showing the same setup or have students try the cold-cup-on-the-counter version at home.
