Ever feel like it’s nearly impossible to get kids excited about physical science? Changing the physical state of a common material can be all it takes to boost student engagement and curiosity. Water easily shifts between a solid, liquid, and gas at temperatures you can safely replicate in the classroom or home kitchen. Sprinkle these easy ice science experiments into your science lessons with kids to help them visualize physics concepts they would otherwise only read about in textbooks.
In these fun ice experiments, children will predict, measure, and analyze what happens to matter as it changes temperature and chemical composition. Here is everything you need to know about conducting simple ice experiments in the classroom.
How Do Fun Ice Experiments for Students Work?
Fun ice experiments allow kids to learn STEM concepts like phase changes, heat energy transfer, and density through hands-on activities. From tossing frozen blocks into hot water bowls, students observe exactly how chemicals interact with temperature shifts. If you’re teaching students about changes in state as part of your science curriculum, try using these ice experiments for kids to enhance lesson plans.
- STEM Lesson: States of Matter
Real World Connection: How liquids, solids, and gases interact
Ice Experiment Activity: Compare melt rates between different ice shapes
- STEM Lesson: Density
Real World Connection: Why objects float in freshwater but sink in saltwater
Ice Experiment Activity: See which liquid ice cubes float in
- STEM Lesson: Thermal Energy Transfer
Real World Connection: How heat flows from hot things to cold things
Ice Experiment Activity: Make ice blocks cold enough to freeze boiling water
Why Conduct Ice Science Experiments With Kids?
Each ice experiment helps kids develop skills that encourage STEM success later in life. Not only do these activities provide accurate STEM demonstrations, but they also create environments where children feel safe to ask questions and explore solutions.
Kids Learn About Heat Transfer and the Three States of Matter
When placed in the freezer, water molecules link to create crystalline ice. As students apply heat by adding salt or exposing cubes to warm air, they discover that heat energy always transfers from higher concentrations to lower concentrations.
Students Develop Observation Skills by Making Predictions
The scientific method is based on asking questions and recording results. You can help students practice the scientific method by asking them to predict which ice block will melt first under a variety of conditions. Predicting melt rates lets kids practice hypothesizing, recording data, and measuring time.
7 Fun Ice Experiments Students Can Conduct at Home or School
Have no fear! All of these activities require minimal supplies and preparation time. Many only use household supplies you probably already have stocked in your kitchen.
Experiment #1 | Salt and Ice Cubes Melting Race
- Goal: Test how additives influence melting times.
- Materials:
- Two identical ice cubes
- Table salt
- Two plates
- Timer or stopwatch
- Steps:
- Place one cube on each plate.
- Pour salt on one cube.
- Start your timer and observe which cube melts faster.
Science Behind the Fun
Salt prevents water from freezing through a process called freezing point depression. Adding salt to a frozen cube destabilizes the liquid’s balance. The ice cube melts because the liquid must remain liquid at lower temperatures when salt is present.
Experiment #2 | Ice Dig Activity
- Goal: Turn temperature energy concepts into a playful game.
- Materials:
- Large plastic storage bin
- Small plastic figures (animals, dinosaurs, etc.)
- Water
- Mini squeeze bottles filled with warm water
- Salt
- Steps:
- Freeze the small toys inside a large ice cube.
- Provide students with tools to release the frozen objects, including eyedroppers, warm water, and salt.
Science Behind the Fun
Warm temperatures and salt both help frozen cubes melt faster by speeding thermal energy transfer.
Experiment #3 | Colored Ice Blocks
- Goal: Allow kids to express creativity while learning about ice.
- Materials:
- Ice cube tray
- Food coloring
- Water
- Heavy paper such as cardboard or card stock
- Salt
- Steps:
- Mix water and food coloring.
- Freeze.
- Allow kids to rub dying ice cubes across salted paper.
Science Behind the Fun
Watching colored water melt across salted paper creates art while reinforcing science concepts about phase changes.
Evaporation, Sublimation, Condensation Quiz
____ is when a solid changes to a gas.
- Evaporation
- Sublimation
- Condensation
Answer: Sublimation! This occurs when dry ice begins to vaporize at room temperature.
Experiment #4 | Make Ice Out of Ice
- Goal: Show students how liquid water can instantly freeze when exposed to ice.
- Materials:
- Bottled drinking water (preferably in plastic bottles)
- Deep freezer
- Ice cube on a plate
- Steps:
- Freeze plastic bottles of water until they are very cold but still liquid.
- Pour liquid water onto ice cube.
Science Behind the Fun
Liquid water freezes rapidly when it comes in contact with a solid ice structure. The immediate freeze creates towers of ice that seem to appear from nowhere.
Experiment #5 | DIY Colored Bubbles Using Dry Ice
- Goal: Impress students by making gigantic transparent bubbles.
- Materials:
- Dry ice (frozen CO2)
- Warm water
- Bowl
- Strip of cloth or fabric
- Liquid dish soap
- Steps:
- Fill a bowl with warm water.
- Place a chunk of dry ice in water.
- Dip a cloth strip into dish soap liquid.
- Move the soap-coated fabric across the top of the bowl to create a film.
- Watch as carbon dioxide expands, filling the bubble with fog.
Science Behind the Fun
Dry ice is frozen carbon dioxide. As the cold CO2 absorbs heat, it releases gas that inflates your bubble.
Experiment #6 | DIY Fog Using Dry Ice
- Goal: Create a dense fog that kids will never forget.
- Materials:
- Dry ice
- Warm water
- Clear glass container (like a beaker)
- Steps:
- Fill any clear container with warm water.
- Place a small piece of dry ice in water.
Science Behind the Fun
Carbon dioxide changes from a solid to a gas at room temperature. As the gas escapes, it rapidly cools the air around it, forcing moisture in the air to condense onto millions of tiny ice crystals.
Experiment #7 | Ice Cube Float Test
- Goal: Teach kids about buoyancy using easy science projects for kids.
- Materials:
- Water
- Cooking oil
- Rubbing alcohol
- Ice cubes
- 3 clear cups
- Steps:
- Fill all cups with a different liquid.
- Place one ice cube in each cup.
Science Behind the Fun
Ice cubes float in water because they’re less dense than liquid water. However, cubes will sink in alcohol (regular blue rubbing alcohol works!) because alcohol is less dense than frozen water.
Are Dry Ice Experiments With Kids Dangerous?
Dry ice is perfectly safe to use during classroom science experiments as long as adults establish and follow clear safety guidelines. At -109.3 degrees Fahrenheit, dry ice can damage skin like an open flame would.
Ice Experiments and Student Safety Tips
- Educate students on the importance of wearing gloves when handling dry ice.
- Demonstrate proper handling techniques including the use of tongs.
- Never seal dry ice in an airtight container.
- Always use dry ice in open, well ventilated areas.
Can We Use Ice for Other Science Projects?
Besides these fun ice experiments, many easy science projects for kids only require a trip to your freezer. Try freezing distilled water into bottles, then use them to demonstrate rapid freezing in liquid water.
Students See Thermodynamics in Action With Ice Experiment Lessons
What Science Lessons Do Easy Ice Experiments Teach Students?
Many of these ice activities cover several different subjects in basic physical science.
Phase Changes and How Matter Changes Temperature: Contrasting between melting and sublimation helps kids understand the importance of molecular structure.
Mass vs Weight: Water weighs less than oil. When students place cubes into different liquids, they discover buoyancy is affected by molecular density.
Where Can Parents and Teachers Find Ice For School Experiments?
Teachers and learning coordinators should focus on establishing strong relationships with ice suppliers. Ice for your typical ice cube trays can come from your home freezer, but block ice and dry ice should be supplied by commercial vendors.
Whether you choose to build your own ice cubes from purified water or purchase colorful ice cubes for kids online, there are multiple ways parents and teachers can procure ice for classroom use. Learn more about harvesting and storing ice by contacting your local schools’ science department today!
