SKYWARD BOUND
Skyward Bound: The Journey Begins
How does water escape the Earth and travel into the sky? Today we explore the invisible forces driving the water cycle: solar energy and phase changes.
Grade 3-5 Earth Science Driven by Solar Energy
THE ENGINE Powering the Cycle
SOLAR POWER
The Sun: Our Engine in the Sky
Without the Sun, the water cycle would completely freeze! The Sun radiates solar energy (thermal energy) down to Earth's oceans, lakes, and rivers.
Energy Transfer
Thermal energy warms up the surface water molecules, causing them to move faster and faster until they break free!
1. Thermal Energy Warms the Liquid Molecules speed up!
How thermal energy drives the cycle Slide 2 of 6
PHASE CHANGE 1 Liquid to Gas
EVAPORATION
Liquid → Gas
Water vapor is completely invisible to our eyes!
What is Evaporation?
As liquid water absorbs thermal energy, molecules break their surface bonds and float up as an invisible gas called water vapor.
Puddles Dry Up Heat from solar radiation turns wet ground into dry air.
Ocean Escape Salt stays behind; only pure water evaporates into the atmosphere!
Invisible water vapor ascends into the atmosphere Slide 3 of 6
PHASE CHANGE 2 Gas to Liquid
CONDENSATION
What is Condensation?
As warm water vapor rises higher, the atmosphere grows colder. Water vapor loses its thermal energy, slows down, and clusters back into tiny water droplets.
Cloud Formation
Millions of microscopic condensed droplets cling to dust particles in the air, gathering together to create the clouds we see in the sky.
Gas → Liquid
Cooling down causes molecules to pack tightly again.
Cooler temperatures in the upper atmosphere transform water vapor into clouds Slide 4 of 6

LAB: Cloud in a Jar
Investigating thermal energy, evaporation, and condensation in a closed microclimate.
The Science Goal
How do cold air and warm air interact to create a cloud? By simulating thermal energy differences in a sealed jar, we will observe phase shifts right before our eyes.
Materials Needed
Glass Jar & Lid
Ice Cubes
Hot Water
Hairspray / Match
Think Like a Scientist (Hypothesis)
If we pour hot water into a jar, place cold ice on the top lid, and spray a small amount of aerosol (to act as dust particles), then a cloud will form in the jar because...
Draw Your Observation
[ Draw the jar, label: 1. Hot Water, 2. Ice Lid, 3. Cloud Vapor ]
Bottom: Warm Liquid Top: Cold Gas
Lab Observations
1. Minutes 1-2 (Evaporation phase):
Describe what you see rising from the hot water:
2. Minutes 3-5 (Condensation phase):
Describe what forms near the ice lid when hairspray is added:
Lab Reflection Questions
1. Thermal Energy Connection: What provides the thermal energy in our real atmosphere to start evaporation?
2. Condensation Catalyst: Why did we need to spray hairspray (or light a match) inside the jar to get a visible cloud?
3. Energy Flow: Did the water vapor GAIN or LOSE thermal energy when it hit the ice at the top of the jar?

Gravity and Flow Worksheet Aqua Quest Unit • Lesson 2 Name: ______________________ Date: ________
Gravity & Landscape Flow
Investigating gravity's pull: precipitation, runoff, infiltration, and basin collection.
Earth's Heavy Puller: Gravity! If the Sun is the "engine" that lifts water up, Gravity is the silent force that pulls it back down. As water drops in clouds grow too heavy, gravity brings them to earth, guiding them down slopes and soaking them deep into the soil.
Part 1: Map the Downward Journey
Station A
Precipitation
Station B
Runoff
Station C
Infiltration
Station D
Collection
Match each Station Letter (A-D) to its corresponding description below:
Water pools in oceans or rivers.
Gravity pulls rain from heavy clouds.
Water sinks directly down into soil layers.
Water slides quickly downhill over slopes.
Part 2: Gravity & Landscapes Fill-in
gravity precipitation runoff infiltration
1. As droplets inside clouds gather and grow heavier, the pull of _____________________ becomes stronger than air resistance, resulting in _____________________ falling.
2. When rainwater lands on a steep mountain slope, it travels down as _____________________ until it reaches a low-lying valley or basin.
3. On flat soil, gravity pulls water straight down, starting the process of _____________________, which hydrates plant roots and refills aquifers.
Part 3: Deep Thinker Question
If Earth had much weaker gravity (like our Moon), how would precipitation and cloud formation be affected? Explain.

The Water Cycle
How water moves endlessly through Earth's atmosphere, landscapes, and oceans.
Sun's Heat Provides Thermal Energy
Condensation Vapor cools & forms tiny cloud droplets.
Evaporation Liquid → Gas
Precipitation Heavy droplets fall
Peak (Solid)
↔
Oceans (Liquid)
Runoff
Gravity slides water downhill over slopes and rocks.
Infiltration
Gravity pulls liquid straight down into dry soil pores.
Collection
Water gathers in major ocean and lake reservoirs.
Thermal Energy Transfer
The Sun radiates heat. Adding thermal energy makes liquid water molecules move faster and escape as vapor. Losing thermal energy cools vapor back into clouds.
The Force of Gravity
Gravity pulls condensed water droplets back down to Earth's surface as precipitation. Gravity also moves surface water downhill (runoff) or down into ground cracks (infiltration).

Assessment Rubric & Answer Key
Grading rubric for student self-evaluation and key criteria for full scientific understanding.
H2O Explorer Scoring Rubric
Criteria Beginning (1 pt) Developing (2 pts) Proficient (3 pts) Core Vocabulary Confuses basic definitions (e.g., evaporation vs condensation). Can define core terms but struggles to explain soil infiltration/runoff. Accurately defines all 6 key cycle terms with real-world examples. Force & Energy Connect Does not identify how gravity or the Sun impacts the water cycle. Identifies that the Sun heats water, but misses the role of gravity. Clearly explains how Sun drives lift (evaporation) and gravity pulls down (precipitation). Experimental Evidence Draws basic diagram but lacks scientific labeling or notes. Records lab steps correctly but struggles to synthesize conclusions. Uses visual labeling, detail, and answers lab questions with scientific facts.
