Instant Ice Science Experiment for Kids

Sharing is caring!

• Facebook 210
• Pinterest 82

This easy instant ice science experiment requires very few supplies but has a big impact. All you’ll have to do is pour liquid water and watch it magically turn into ice before your eyes!

See the Instant Ice Science Experiment in Action

• Bottled water
• Glass or ceramic bowl
• Plastic tray or shallow metal cookie sheet
• Curious kids

• Put water bottles in the freezer for two hours. (You might want to set a timer to remind you to get them out!) Lay them on their sides for the best results, but try not to dent them.
• Remove the water bottles from the freezer before they freeze. (You’ll know they’re ready when crystals form when you jostle the bottles.)
• Place a ceramic bowl upside down on a flat surface (like a tray) to catch the water overage.
• Place an ice cube on top of the pouring surface.
• Then SLOWLY pour while instant ice forms!

How the Instant Ice Science Experiment Works

This simple but amazing instant ice science experiment is more than just a cool one (see what I did there?). The science behind this experiment lies in the freezing temperature of water and how ice crystals form. This experiment is sometimes referred to as Supercooled Water or Flash Freezing. When the freezing temperature is reached, the water molecules freeze by forming ice crystals.

Why did we put an ice cube on top of the bowl? Because it’s easier for the water molecules to turn to ice on top of already-formed ice crystals. As the ice crystals build on existing ice crystals, they eventually freeze the entire bottle of water.

The process of starting the ice crystals is called “nucleation.” Nucleation starts from an impurity or scratch or piece of dust on the container holding the water. In this case, the nucleation is the water bottle. One ice crystal attaches to the imperfection, and the others grow on top. Isn’t science cool?!

Check for Understanding

Explore this concept further by asking your kids these questions and experimenting:

• Would the experiment work the same if the water had food coloring added to the water?
• Would the results be the same if you started the experiment with hot water in the bottles before you put them in the freezer?
• Does the temperature in the room change the results?
• How high of an ice tower can you pour before it breaks?

What Makes Ice Melt Faster?

What makes ice melt faster? Let’s investigate with simple ice melting experiments that kids of varying ages can enjoy. Learn about lowered freezing points, freezing depression points, and more! We love simple science experiments for kids!

Free Printable Ice Melting Experiment Worksheets!

Let’s get right to learning all about ice. Head to the kitchen, open the freezer and be prepared to experiment with these different ice projects.

Grade Level: Suitable for Kindergarten through 3rd Grade

Project #1: What Makes Ice Melt Faster?

In this experiment, you will investigate what makes ice melt faster, by adding several different solids to your ice. Make sure to use the scientific method and pick variables for this project.

💡 Make ice cream in a bag and homemade slushies to explore the concepts further.

Supplies Needed:

• Muffin tin, jars, or containers
• Various solids. You can start with table salt and sugar, but also include different types of salt, baking soda, sand or dirt etc.
• Stopwatch or clock to determine the time of the experiment

Experiment Set Up:

STEP 1: Add 4 to 5 ice cubes to 6 cupcake cups. Make sure the same amount of ice is in each one.

STEP 2:  Add 3 tablespoons of each solid to a separate container of ice. 

• Add 3 tablespoons of baking soda to cup #1.
• Add 3 tablespoons of salt to cup #2.
• Add 3 tablespoons of sand to cup #3.

Cup #4, cup #5 and cup #6 are your controls and will have nothing added to the ice.

STEP 3: Set the timer to check back on the ice cubes every 10 minutes over 1/2 hour and record your results. Then draw your conclusions.

What did you find caused the ice to melt fastest?

EXTENSION: Use a timer to record how long each material took to melt the ice. Record the results. Try adding solids of your own choice and record that data, too. Now, turn the data into a graph!

Science Explanation: Why Does Salt Melt Ice?

Unsurprisingly, adding salt (sodium chloride or NaCl) made the ice melt fastest. Baking soda was second as it’s a type of salt and can lower the freezing point of water. However, it is a powder. Sand did not do much! So why does salt melt ice?

Salt lowers water’s freezing or melting point. It interferes with ice crystals, and by mixing with the liquid water on the melting ice, it speeds up the melting process. This is also called a lowered freezing point.

💡 Read more about the Freezing Point Depression further below.

Project #2: How Quickly Can Ice Melt?

In this experiment, you will explore how quickly you can melt a pile of ice cubes! At what temperature does ice melt? Read on to learn more!

The challenge is to see how quickly you can melt the ice cubes. This can be done individually or in small groups. If you choose to use the small group format, make sure to allow a few minutes for the kids to brainstorm ideas together.

• Paper towels
• Optional: Table Salt (sodium chloride, NaCl), Cloth, Paper, Small Plastic Food Containers

STEP 1: Give each kiddo or group of kids the materials, including paper towels and a specific number of ice cubes on a plate.

STEP 2: Encourage the kids to use the materials to try and melt the ice quickly!

STEP 3: When the race is over (set a specific amount of time that works for you), ask groups to share the steps of their melting process. Discuss what worked and why. Also, discuss what you would do differently the next time!

💡 Use a timer and record how long it took each kiddo or group of kids to melt the ice. Record the results. Try two more times and record that data. Now, turn the data into a graph!

The Science: Freezing Point Depression

Freezing point depression explains why adding something to a liquid, like salt to water, can cause it to freeze at a lower temperature than it usually would (lowered freezing point).

Here’s an example to help you understand: Think about plain water. It freezes and turns into ice at 32°F (0°C). But if you add salt (sodium chloride) to the water, the freezing point drops. The water now has to be even colder than 32°F to freeze! This is why salt is often spread on icy roads in winter – it helps melt the ice by lowering the water’s freezing point.

💡 The salt and water, when mixed, become a chemical solution !

In simple terms, adding certain substances (like salt) to a liquid makes it harder for that liquid to freeze! Ice at the freezing point of water has less energy or heat than water at the same temperature!

💡 Learn more about the freezing point of water with our freezing water experiment .

More Ways to Melt Ice Cubes

There are many possible ways to melt ice. The simplest way is just to leave the ice to melt at room temperature. The heat energy in the warmer room works to break up the ice structure to turn it to water. We see this all the time with the ice cubes in our drink glasses or if we accidentally leave one out on the counter.

You could hold the ice cube in your hand (brrr, chilly) to speed up the melting process since your body is usually warmer than the room. To make it melt even faster this way, try rubbing your hands together really fast before holding the ice cube. Rubbing your hands together quickly creates friction, which adds more heat through an increased temperature!

Another way to generate more heat and a higher temperature is to rub the ice cube on a piece of cloth.

How about placing the ice cube on a dark piece of cloth or paper and placing it in sunlight? Dark colors retain heat from sunlight better than light colors, so you might feel hotter wearing a dark T-shirt in the middle of a hot summer day!

💡 See our what colors absorb heat best experiment.

Project #3: How Do You Keep Ice From Melting?

In this third experiment, you will investigate how to keep ice from melting. Instead of seeing how fast ice melts, let’s try to keep it cool instead!

The challenge is to see how slowly you can keep the ice from melting by reducing the amount of heat or energy that surrounds the ice. This can also be done individually or in small groups. Remember, if you do choose to use the small group format, make sure to allow for time for the kids to brainstorm ideas together.

• Small zip-top bags
• Small plastic containers (as close to the same size as possible so they are uniform)
• Various materials (eg Aluminum foil, cotton balls, paper towels, rubber bands)

💡 There are quite a few items that can be potentially used for this ice cube insulation challenge! Check out the recycling bin, junk drawer, garage, and more. This is also where our dollar store engineering kit comes in handy. You can use the items you have available for a budget-friendly STEM challenge.

STEP 1: Brainstorm. What are the best materials available to keep the ice from melting?

STEP 2: Decide what materials or combination of materials you want to use to keep your ice cubes from melting by insulating them! Create one or more insulated containers to test your ideas. You can choose a specific amount of time for this portion of the project or split the STEM challenge up over several days.

STEP 3: When all the insulated containers are finished, place an ice cube in a small zip-top plastic bag and then place it in the insulated container. Make sure to put the lids on!

💡 As a control , you will want to place a zip-top bag, with an ice cube into it, in a similar container that is not insulated. This control container is for comparison. By creating a control, you make it possible to determine whether the materials (variables) you chose are responsible for the outcome!

STEP 4: Place all the containers in a cool dry place away from a heat source or direct sunlight. No extra energy is needed here!

STEP 5: Check your containers every 10 minutes. Notice any differences Record your observations until all of the ice is completely melted. Make sure you do not handle the ice or remove the ice from the container while you make your observations.

STEP 6: Think about what materials worked best and why. How can you improve your results?

Science Explanation: How Insulation Works

Everyone knows that when you remove ice from the freezer, it will melt over time. However, most of us don’t think about why it happens. The air around the ice cubes is usually warmer than the ice and it causes the ice (solid) to change into water (liquid). States of matter too!

So, if you do not want the ice to melt, you need to keep the warm air (heat energy) away from the ice by using an insulating material. Some great insulators just for a hint are felt, newspaper, and wool. Insulation prevents the transfer of heat to the ice so the ice crystals stay icy and cold longer.

Insulation is also used to keep our houses warm in the winter in cold parts of the world by keeping the cold out! Additionally, insulation can keep the heat out of a house on a hot day too! Insulation can keep up comfortably when the temperature drops and when it rises!

This is a fun, non-toxic project for kids of all ages, and the best part is you likely have everything you need at home. All you need is ice, salt, and food coloring.

You can use any type of salt for this project. Coarse salt, such as rock salt or sea salt , works great. Table salt is fine. Also, you could use other types of salt besides sodium chloride (NaCl). For example, Epsom salts are a good choice.

You don't have to color the project, but it's a lot of fun to use food coloring, watercolors, or any water-based paint. You can use liquids or powders, whichever you have handy.

• Food coloring (or watercolors or tempera paints)

Experiment Instructions

• Make ice. You can use ice cubes for this project, but it's nice to have larger pieces of ice for your experiment. Freeze water in shallow plastic containers such as disposable storage containers for sandwiches or leftovers. Only fill the containers part way to make relatively thin pieces of ice. The salt can melt holes all the way through thin pieces, making interesting ice tunnels.
• Keep the ice in the freezer until you are ready to experiment, then remove the blocks of ice and place them on a cookie sheet or in a shallow pan. If the ice doesn't want to come out, it's easy to remove ice from containers by running warm water around the bottom of the dish. Place the pieces of ice in a large pan or a cookie sheet. The ice will melt, so this keeps the project contained.
• Sprinkle salt onto the ice or make little salt piles on top of the pieces. Experiment.
• Dot the surface with coloring. The coloring doesn't color the frozen ice, but it follows the melting pattern . You'll be able to see channels, holes, and tunnels in the ice, plus it looks pretty.
• You can add more salt and coloring, or not. Explore however you like.

Clean Up Tips

This is a messy project. You can perform it outdoors or in a kitchen or bathroom. The coloring will stain hands, clothes, and surfaces. You can remove coloring from counters using a cleaner with bleach.

How It Works

Very young kids will like to explore and may not care too much about the science, but you can discuss erosion and the shapes formed by running water. The salt lowers the freezing point of water through a process called freezing point depression . The ice starts to melt, making liquid water. Salt dissolves in the water, adding ions that increase the temperature at which the water could re-freeze. As the ice melts, energy is drawn from the water, making it colder. Salt is used in ice cream makers for this reason. It makes the ice cream cold enough to freeze. Did you notice how the water feels colder than the ice cube? The ice exposed to the salty water melts faster than other ice, so holes and channels form.
