May 18, 2026 by Annette Kaminsky Leave a Comment

This super-easy expanding balloon science experiment includes balloons and two basic household staples, which is a win-win combination. The bubbly experiment is perfect for all ages, and children can easily help with the activity.

_______

Supplies to Collect

To perform this fantastic chemistry experiment, gather the following inexpensive supplies:

white vinegar
baking soda
large balloon
water or juice bottle
measuring cup (optional)
measuring spoon
funnel

The Expanding Balloon Science Experiment

In this fizzy science activity, start by stretching a large balloon and blowing a little air into it.

Next, let the air out and place a funnel inside the rolled edge. Spoon in three teaspoons of baking soda. If the bottle you will use is on the larger side, use heaping teaspoons of the powder. Shake the balloon a bit to get the baking soda to the bottom.

_______

Then pour vinegar into a clean water or juice bottle and fill it about ¼ to 1/3 of the way. Pour the vinegar into a measuring cup first to make this step easier.

Afterward, carefully fit the balloon snugly over the mouth of the bottle. Keep the balloon hanging off the side as you do this.

_______

Lastly, lift the balloon so the baking soda drops into the bottle and watch the two ingredients bubble and fizz as they react. The balloon will magically self-inflate.

_______

The Science Behind This Balloon Experiment

Vinegar is a liquid, and baking soda is a solid. In this bubbly, fizzing science experiment, there is a chemical reaction between the vinegar (an acid) and the baking soda (a base). As the two ingredients interact, they release carbon dioxide gas. The gas expands and goes up the balloon, causing it to inflate.

_______

Variations of the Expanding Balloon Science Experiment

To extend this magical science activity, try using different-sized bottles and varying amounts of vinegar and baking soda to see if the experiment works out just as well.

_______

To make the eye-appealing activity even more colorful, add food coloring to the vinegar in the bottle and use a clear balloon.

Salt and Ice Science Experiment

May 20, 2025 by Annette Kaminsky Leave a Comment

_______

This salt and ice science experiment is simple to set up and fun to do. Just a few supplies are needed for this ice-cold science activity. It’s perfect on a hot day, and makes a good pirate theme or Mother’s Day activity.

_______

Supplies to Collect

Gather the following supplies for this ice and salt science experiment:

food storage trays
food coloring
acrylic gems
bowl with salt
teaspoons
paint pot with water
eye droppers or pipettes
play tweezers
tray
safety glasses
waterproof table cover

_______

_______

Preparing the Salt and Ice Science Experiment

To prepare this science experiment, freeze gems in ice for two or three days.

Start by adding a layer of water with a few squirts of food coloring stirred in to the bottom of a food storage tray. Liquid watercolor paint also works well to tint the water.

Next, spread a handful of acrylic gems in the liquid. Then, carefully set the tray in the freezer.

Remove the tray from the freezer and add more water and gems the following day. Freeze the tray overnight again.

The third day, the ice is ready for the science and sensory activity. Many gems will be near the surface of the ice, and some may be sticking out a little. This is fine for younger children.

_______

To add more challenge for older children, pour a thin layer of water over the frozen gem-filled ice and freeze the tray again before setting out the activity.

_______

The Salt and Ice Science Experiment

When the layers of water are frozen, remove the ice from the food storage tray and set it on a large, edged tray placed on a table protected with a waterproof table cover.

_______

Add a bowl of salt with a teaspoon, an eye dropper or pipette in a paint pot filled with water, and a small bowl ready for freed gems. Include a set of play tweezers and a second teaspoon on the tray.

Drip water and sprinkle salt on the ice, and pry out the gems using teaspoons and tweezers. The salt and ice help melt the ice, making the removal of gems quicker and easier. Note: Safety glasses are recommended for this activity as gems may pop out of the ice. Check freed gems for broken edges and discard them.

_______

_______

Variations of the Salt and Ice Science Experiment

For variety or to use supplies on hand, replace the acrylic gems in this salt and ice science experiment with pom poms or animal figurines. Ocean animal figurines are a popular choice for this activity.

_______

Skip adding food coloring to the water during the freezing process. Note: The ice will be a little clearer if you use filtered or distilled water.

Offer the activity to a group of children by freezing four or more trays of gem-filled water and setting the supplies for each participant in a large active world tray.

_______

Explaining the Salt and Ice Science Experiment

Salt lowers the temperature of water. For this to happen, it must be in a solution with liquid water. The salt and water solution created in this experiment melts the ice quicker than letting the ice liquify on its own.

_______

Tying In Mother’s Day

This salt and ice science experiment is a perfect Mother’s Day activity. After freeing gems from ice, allow participants to pick one to glue to a Mother’s Day greeting that says “Mom, you’re a gem.” Allow them to save more gems in a small container to add to their treasure collection.

Candy Cane Wreath Experiment

December 20, 2023 by Annette Kaminsky Leave a Comment

_______

It’s tradition for me to do a candy cane science experiment every December, and each year I arrange the candy canes in a new way or change up the sizes and colors of the sweet treat. In this post, I debut my latest design, a candy cane wreath experiment.

_______

Follow me on Pinterest for more early learning ideas.

_______

Supplies to Collect

Gathering supplies for this simple science experiment couldn’t be any easier. Just select an edged waterproof tray, and purchase a package of candy canes. You may have some on hand already. Then fill a pitcher or large glass with water and you are good to go.

_______

The Candy Cane Wreath Experiment

To perform this inexpensive color science experiment, arrange candy canes around the edge of a waterproof tray in a wreath-like shape.

_______

If you look closely, you’ll notice one or two broken candy canes in the tray and a few oddly shaped ones. This science experiment is the perfect use for them, as I wouldn’t have wanted to hand those out as treats.

Next, slowly pour water into the tray until the candy canes are just covered in liquid.

Then watch what happens. You’ll see the candy cane colors slowly spread through the water.

_______

Note: The color changes happen quickly. Stay by the science experiment and have your camera ready to snap a few pictures.

_______

_______

_______

After a little while, you can carry on with other activities and periodically check in on the experiment to see even more color changes and view the candy canes melting away.

_______

The Science Behind This Candy Cane Color Experiment

Candy canes are made of sugar. The water breaks the sugar molecules apart. Then the food colors move through the water away from areas of higher sugar concentration (near the candy) to areas with less sugar. When the sugar concentration is the same in all areas, the colors stop moving.

Melted Candy Gingerbread Ornaments

December 12, 2023 by Annette Kaminsky Leave a Comment

_______

Making melted candy gingerbread ornaments was something I’ve wanted to try ever since viewing a beautiful four-sided, sweet-tasting red and white gingerbread house on Twitter a few years ago. It’s an eye-pleasing baking activity and a festive science experiment so I highly recommend giving the activity a go.

_______

_______

Melted Candy Ornament Supplies

_______

Gather the following supplies for this simple candy science activity:

red and/or green striped round peppermint candies
metal gingerbread cookie cutters
no-stick cooking spray
parchment or wax paper
cookie pans
cutting board
knife
vegetable oil
wooden skewer

_______

Melted Candy Gingerbread Ornament Tips

Before trying this minty STEAM activity, I read a few blog posts about making melted peppermint candy designs. This detailed Melted Peppermint Candy Ornaments post by onelittleproject.com was particularly helpful and had great tips.

_______

Making The Melted Candy Christmas Ornaments

_______

To make the melted gingerbread candy ornaments, start by picking out metal cookie cutters for the task. Generously sized gingerbread people and a house were my cookie cutters of choice.

Spray the cookie cutters with no-stick cooking spray.

Next, add parchment paper to one or more cookie pans and set the greased cookie cutters on the pans.

Then insert unwrapped red or green striped peppermint candies inside the cookie cutter shapes. For larger spaces, cut candies into halves or quarters on a cutting board and use the smaller pieces to fill in the gaps.

_______

Baking The Melted Candy Gingerbread Ornaments

To bake the candy gingerbread ornaments, set the oven temperature to 350 degrees.

Next, put the peppermint candy-filled cookie cutters in the oven and heat them for around six minutes.

Stay by the oven and make sure to turn the oven light on to view the candies melting. It’s okay to take a peek…the sweet creations won’t jump out of the oven. But they will melt down if they are in the oven too long.

When the candies are joined together and a little of the melted candy starts seeping around the cookie cutter edges, take the baking pans out of the oven.

_______

After around two minutes, dip a wooden skewer in vegetable oil and carefully make a little hole near the top of each decoration so a string can be drawn through. Then let the eye-catching creations cool for around fifteen minutes.

Before the ornaments cool completely, carefully pull away the sides of the cookie cutters from the candy shapes and gently push them out. Oh-so-carefully break off melted bits around the peppermint ornaments if there are any.

Let the beautiful striped ornaments cool completely.

_______

How The Melted Gingerbread Ornaments Turned Out

This is where I need to come clean. My candy gingerbread ornaments didn’t turn out perfectly. Each one had one broken bit. The red and white gingerbread person had two broken bits.

_______

But as a first try at making melted candy ornaments, I considered it a success. I determined afterward that I had left the candied shapes in the oven just a little too long (probably eight minutes) and needed to be even more careful in removing them from the cookie cutters after baking. So a second attempt would likely be more successful.

The activity did turn out well enough that I would confidently be able to introduce it to family members or a group of preschool students. The patterned ornaments were fun to put back together as mini puzzles, and they would be tasty treats broken down into small bits and shared. Broken ornaments could be crushed and infused with playdough or baked in a peppermint cookie recipe when the science experiment was over. And there could be a conversation about stripes, patterns, halves, quarters, and the smell and taste of peppermint.

Striped peppermint candies are economical to buy, and I’ll surely give this stunning melted candy gingerbread ornaments STEAM activity another go. How about you? Will you give it a try?

Dyed Peony Science Experiment

July 2, 2023 by Annette Kaminsky Leave a Comment

_______

Peony plants have large, bold flowers that grow profusely during the blossoming season. It’s always sad to see them go so I try to snap a few pictures before they drop off.

Don’t get scared off by the ants in this picture I took! Ants eat peony nectar and help keep peonies safe by attacking bud-eating insects.

Pretty light pink peony flowers and buds. Peony blooms are showstoppers during the summer season.

_______

After taking a peony and thrifted vintage teacup photo, I realized that a saved flower in a jar of water would provide the perfect opportunity for a dyed peony science experiment. Peony flowers have a dense cluster of petals, similar to carnations, so I wondered if the experiment would turn out as well. It worked wonderfully, so I highly recommend giving it a try.

A pretty in pink peony bloom complements a thrifted vintage teacup.

_______

Supplies To Collect

All you need is a few supplies to perform this oh-so-easy, nature science experiment. Gather the following:

peony flower stem with leaves
clear jar or vase with water
neon blue food coloring
spoon

_______

Warning: All parts of the peony plant contain a toxin and should not be ingested. Please supervise this activity closely. If your participants tend to put things other than food in their mouths, you may wish to choose another flower for this science experiment. This activity is commonly done with carnation flowers.

_______

The Dyed Peony Science Experiment

To perform this simple science experiment, fill a small, clear jar at least half full of water.

Add 10 or more drops of neon blue food coloring and stir it in. I use a blue hue, but any color of food coloring would work nicely.

Try this easy-to-do dyed peony science experiment today. This activity shows how water travels up peony stems and flows through leaves and petals.

_______

Set the sprig in the colored water overnight and observe it the next day. You’ll notice that the edges of the peony flower petals have turned blue.

Check the plant once a day after that to spot more color changes.

_______

Tell your little charges that coloring the water blue helps us see how water travels up the stem of a plant into the flower leaves and petals.

Note: The leaves and stems of my peony plant are dark, so it is difficult to see water travel up them. Choosing a plant with lighter leaves would show water travel through these plant parts better.

Large, light pink peony blooms are showstoppers during the summer season.

_______

The Importance of Water For Plants

Along with light, air, and good soil, water is super important to a plant’s growth and survival:

Plants are made of mostly water, and it helps them stay firm.
Plants cool down by releasing water from their stems and leaves. This helps them regulate their temperature.
Water carries important nutrients that help plants grow.
Sunlight, carbon dioxide from the air, and water are necessary for photosynthesis, which is how the leaves of plants create energy to survive.

_______

If you have an abundance of peonies, why not try this dyed peony science experiment with a variety of food coloring hues? Or you could perform it with carnations, which are easy to find and economical to buy.
