6. 🪟 Window-Bag Water-Cycle Lab
Predict what may appear on the inside of a sealed bag. Then explore the model stages.
Try this practical lab with an adult
You need: a clear resealable bag, a little room-temperature water, a marker and tape.
- Ask an adult to add a little water, seal the bag and mark its starting waterline.
- Have the adult secure it upright at a suitable window, out of reach of children who might pull it down.
- Observe later and on the next day without opening it. Conditions affect whether droplets appear.
- Look for liquid at the bottom and any droplets inside higher up.
Observe and record: Draw what you actually see. Do not assume the bag must change within a fixed time.

7. 🥣 Evaporation Watch Lab
Advance a model observation interval and compare the water in an open dish with water inside a covered dish.
Try this practical lab with an adult
You need: two identical shallow dishes, equal small amounts of room-temperature water, a clear cover and paper.
- Set the dishes side by side where they will not be disturbed. Add equal amounts of water.
- Cover one dish and leave the other open. Mark or record the starting levels.
- Observe over a suitable interval chosen by the adult. Keep the place, dishes and starting amounts alike.
- Look at the water and any droplets under the cover. Do not taste the water.
Observe and record: Record changes without claiming the covered dish has no evaporation. Water can evaporate and condense inside it.

8. 🧴 Cold-Bottle Droplet Lab
Compare a sealed cold bottle and a sealed room-temperature bottle. Explore where new outside droplets can come from.
Try this practical lab with an adult
You need: two sealed plastic water bottles, one chilled by an adult, two dry plates and a cloth.
- An adult prepares one cool bottle and one at room temperature. Keep both sealed.
- Dry the outside of each bottle and place them on separate dry plates.
- Wait and look closely without opening the bottles.
- If droplets appear, note which bottle they are on. Very dry air may give little or no visible change.
Observe and record: Sketch any droplets. Discuss water vapour in the surrounding air and whether the sealed bottles leaked.

9. 🌧️ Rain-Collector Observation Lab
Read three model collection records. Find the greatest amount, then make a sensible note about the dry interval.
Try this practical lab with an adult
You need: a stable straight-sided plastic container, marker, ruler and notebook.
- Ask an adult to choose a safe open location and place the container securely during a suitable rain interval.
- The adult retrieves it. Observe and mark the collected depth with help.
- Empty it after recording; compare another interval of the same duration if practical.
- Keep the container and location consistent. Avoid storms and unsafe outdoor conditions.
Observe and record: Write the date, interval and depth. Different collection durations do not make a fair direct comparison.

10. ⛰️ Rainfall and Runoff Tray Lab
Add model rain to a slope, watch the route and choose where surface water gathers.
Try this practical lab with an adult
You need: a shallow tray, a firm washable sloping surface or a little clean sand, room-temperature water and a teaspoon.
- An adult makes a gentle slope inside the tray and keeps the activity on a protected surface.
- Drip a small amount of water near the higher end using the teaspoon.
- Observe movement toward lower places. If using sand, notice whether some water soaks in.
- Keep all water in the tray and clean up spills with adult help.
Observe and record: Draw arrows showing the route you actually observed. Separate flowing over the surface from soaking into material.

How to use the lab activities
Open the practical-lab instructions inside each activity for materials, steps and an observation prompt. An adult should manage the setup and cleanup. Use small amounts of room-temperature water unless the instructions ask an adult to prepare a chilled bottle. The screen models are simplified and do not predict exact real timings, quantities or weather. Games and labs share one active main workspace; extra practice is independent.

Five Parent and Teacher Tips
Follow one route before exploring others
Begin with lake water, evaporation, cloud droplets, rain and water gathering again. Then explain that water can also soak into the ground or move through other routes.
Keep invisible vapour different from visible droplets
Water vapour is a gas we cannot see. Clouds and condensation droplets contain liquid water or ice. Diagram arrows represent movement rather than visible vapour.
Let students make and check predictions
Ask what they think will happen before a lab. Compare that prediction with the actual observation without treating a different result as failure.
Record the conditions
Note the materials, observation interval and what changed. Real results depend on temperature, humidity, airflow and the setup. Do not invent a measurement to match a model.
Connect the worksheet with a lab
Use the worksheet download already provided on this page for written practice. After a lab, ask the child to sketch the setup and explain one change in a sentence.
Water Cycle Class 2 Notes and Learning Guide
What is the water cycle?
The water cycle describes the continuing movement of water on, above and below Earth’s surface. Water changes place and can change between solid ice, liquid water and invisible water vapour. A water cycle diagram for Class 2 helps children follow a simple pathway through these changes.
Evaporation and condensation
Evaporation changes liquid water into water vapour. The Sun provides much of the energy driving the water cycle, but evaporation does not require boiling or bright sunshine. Conditions affect how quickly it happens. Condensation changes water vapour into liquid water, such as droplets forming on a sufficiently cool surface.
Clouds and precipitation
Clouds contain tiny liquid droplets and may also contain ice crystals. Water vapour itself is invisible. Under suitable conditions, cloud droplets or ice particles grow and fall as precipitation. Rain and snow are examples. Not every cloud produces rain at every moment.
Collection and other water routes
Water can gather in rivers, lakes and oceans. It can also flow downhill as runoff, soak into the ground or remain temporarily in a puddle. The four-part water-cycle model is a useful introduction, rather than a complete route followed by every drop. There is no single permanent starting or finishing point.
Learning through practical activities
The window-bag lab connects evaporation, condensation and returning drops. The open-and-covered dishes help students think about where water goes. A chilled-bottle comparison explores droplets on a cool surface. Rain records and a runoff tray connect observations with collection and surface flow. Students should describe what actually happens, including little or no visible change.

Water Cycle Class 2 Questions and Answers
What is the water cycle for Class 2?
The water cycle is the continuing movement of water between places such as water bodies, the air and the ground. Water can also change form during this movement.
What are the four water-cycle stages taught in Class 2?
Evaporation, condensation, precipitation and collection are four useful introductory stages. Real water can take additional routes, including movement through soil and plants.
What is evaporation?
Evaporation is the change from liquid water to water vapour. Water vapour is an invisible gas.
What is condensation?
Condensation is the change from water vapour to liquid water. Droplets on a sufficiently cool surface are a familiar example.
What is precipitation?
Precipitation is water falling from clouds to Earth’s surface. Rain, snow and hail are examples.
What does collection mean in the water cycle?
Collection describes water gathering in places such as rivers, lakes and oceans. Water may also gather temporarily in puddles or move into the ground.
What does the Sun do in the water cycle?
The Sun supplies much of the energy driving the water cycle, including energy used in evaporation.
Can water evaporate without boiling?
Yes. Evaporation can happen from liquid water without boiling. Temperature, airflow, humidity and exposed surface area can affect its rate.
Are clouds made only of water vapour?
No. Visible clouds contain tiny liquid droplets and may also contain ice crystals. Water vapour itself is invisible.
Does the water cycle stop after rain?
No. Water continues moving and changing form. Some rainwater flows, soaks into the ground, gathers or evaporates again.
Why is the water cycle important?
It moves water through the environment and connects water bodies, the air, the ground and living things. A continuing cycle does not make safe freshwater unlimited.
Which water-cycle practical activities can Class 2 students try?
With adult help, students can observe a sealed window bag, compare open and covered dishes, inspect a chilled bottle, record collected rain and explore runoff in a tray. Record actual results rather than expecting every setup to behave exactly like a diagram.
