Candy Cane Science Experiment

January 1, 2022 by Annette Kaminsky Leave a Comment

_______

This Christmas I went on a candy cane hunt, primarily to add a few of these festive treats to my preschoolers’ party bags. Although easy to find in the past, I visited three different stores before I spotted some.

Candy canes had been brought up in class discussions, so I thought the children would be excited to discover them in their party bags. As I tried to give one child extra candy canes for his siblings, I noticed that he was furiously trying to give his original ones away. It turned out that he immensely dislikes them! So needless to say, there were a few candy canes leftover at school after the holiday celebrations.

So then came Plan B…the decision to use some for this easy-peasy candy cane science experiment.

_______

Supplies To Collect

Gather just three supplies for an easy-to-perform candy cane or candy experiment with a WOW factor.

_______

The supplies for this science experiment couldn’t be any simpler. Gather the following three things:

white or cream-colored dinner plate with a rim
cup of warm water
two large candy canes

_______

Conducting The Candy Cane Science Experiment

Try this candy cane Science experiment today! It is easy to do and has immediate results.

_______

Place two candy canes in the center of the plate in a heart shape.

Slowly pour in warm water to a level just beneath the plate rim.

The food coloring will immediately diffuse from the candy canes, and the color patterns will change right before your eyes!

This experiment can be tried with other colors of these treats. The red, pink, and white color scheme below would work perfectly for Valentine’s Day.

_______

Variation Of The Candy Cane Experiment

There was a second candy escapade this holiday season, as a type of striped, spherical, Christmas candies I purchased turned out to be much too hard. I tasted one, and it just wouldn’t dissolve in my mouth. I imagined students choking on the candy on the drive home from preschool, and didn’t want to risk that. As you might have guessed, the super hard candies didn’t make the treat bag cut.

Conveniently, these holiday candies work in the same science experiment. In the picture below, the candies are arranged next to the rim of a plate. When warm water is added, green and red food colors slowly move through the liquid away from the candies. The process is so slow, the colors blend to make a rich brown hue soon after they spread. Since little learners love mixing colors to make brown, they would be excited to see this!

An oh-so-easy Christmas candy science experiment. Can't you smell the candy already?

_______

The candies can be placed a little farther apart around the plate rim, so the colors don’t mix as quickly when water is added. Or they can be spread apart as in the picture below. Then moving red and green colors are visible a little while after warm water is added.

Try this Christmas candy Science experiment today! It is easy to do and has immediate results.

_______

Tip: If the colors in the candies dissolve at a snail’s pace, as in one of my experiments, you can choose to use hot water. This will speed up the scientific process. Make sure little learners observe what happens only with their eyes, keeping their hands and bodies away from the plate.

After the science experiment is finished and the liquid is cool, you may wish to let your little charges taste a teaspoon of colored water. It will have a strong mint taste.

_______

Explanation Of This Candy Cane/Candy Experiment

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

Water temperature is a variant in this experiment. Sugar dissolves quicker in warm water, and food coloring moves at a faster paste.

This science experiment is so easy to set up and has immediate results, perfect for little learners. And participants get to use their senses of sight, smell, taste, and touch. Try it today with candies or candy canes!

Turtle Pond Sensory Bin

November 4, 2021 by Annette Kaminsky Leave a Comment

Easy to sert up nature-based tutle pond sensory bin.

_______

Why debut a turtle pond sensory bin, eggs included, in fall? Because although we generally associate spring as the time for baby animals to be born, many turtle hatchlings peck out of their shells in autumn.

And…because I have a light-up “toss and dive” turtle set that I’ve longed to use for over two years! I never stored it in a permanent spot because I was always planning to do a pond activity “very soon.” But with so many fantastic curriculum ideas to choose from every week, “soon” never came.

So this September as I was reorganizing storage areas, I noticed the colorful turtles once again. I googled “turtles in fall” to see how I could use them alongside typical fall themes such as leaves, pumpkins, bats, and spiders. Finding that turtle eggs and hatchlings are part of the fall season motivated me to include the diving turtles in a sensory activity at this time.

_______

Ten Turtle Reproduction Facts

Although turtles spend a lot of time in water, nearly all lay their eggs on land.
Many turtles lay a clutch of eggs in about 3 – 6 weeks after mating.
Mother turtles dig a nest in sandy or wet dirt with their hind legs. They cover the eggs laid in the nest with soil and plants.
Depending on turtle size and species, there can be from 5 to 100 eggs in a clutch.
Most turtles don’t guard their nests, leaving right afterwards.
It takes the baby turtles two to three months to hatch.
Most hatch in autumn, pecking their way out with an egg tooth.
These fall babies often stay in the nest through winter and emerge the following spring.
They survive their first winter by not eating and living on their own fat reserves. Some can handle cold temperatures and may even produce a sort of antifreeze.
Only a few turtles survive to adulthood. Turtle eggs and hatchlings have many predators.

_______

Turtle Pond Supplies To Collect

Loose parts for a turtle-themed sensory bin.

_______

A turtle-themed sensory bin can be set up very quickly with the following supplies:

kitchen supply bus bin
turtle figurines
rocks of varying sizes
small logs or twigs
gemstone slices
real or artificial leaves
marbles
small disposable food container with a ridge
a large piece of brown craft foam

_________

Making The Turtle Pond Sensory Bin

Nature[ based, easy to set up turtle pond sensory bin.

_______

Pour a layer of water into the bin. I used a kitchen bus bin for this activity.

Add rocks, logs, and gemstone slices.

Cut a few curves around the edge of the foam, and a hole in the middle just big enough to fit the disposable container. Float the foam in the water.

Set the disposable container in the hole to represent a turtle nest.

Add marble “eggs” to it. I used blue marbles because they were handy, but real turtle eggs are white or cream-colored.

This turtle pond sensory bin includes a sunken nest with "eggs."

_______

Surround the “nest” with a few craft or real leaves for covering the eggs up.

Add turtle figurines. Three light-up “toss and dive” turtles are the stars of this sensory bin, but any turtle figurines would be heartily welcomed by early learners.

Felt Pen Chromatography Experiment

October 30, 2021 by Annette Kaminsky Leave a Comment

_______

This felt pen chromatography experiment uses supplies from the kitchen, has quick results, and can be tailored to a variety of topics. Creativity and center play is easily incorporated. And the experiment is super family-friendly.

_______

Basic Felt Pen Chromatography Experiment

See what colors felt pens are really made up of with this felt pen chromatography experiment.

_______

The simplest version of this experiment is to draw three filled-in circles with nonpermanent felt pens near the bottom of a section of paper towel.

Add a thin layer of water with 2.5 ml salt stirred in to a measuring cup or jar. Place the towel with the colored side down into the container. The water level should sit just below the felt pen colors.

Simply watch what happens!

After the color movement stops, remove the paper towel from the container and let it dry flat. Discuss the color changes/new color results.

_______

Felt Pen Chromatography Experiment Scary House

Scary house imaginative play with a felt pen experiment chromatogram.

_______

Although I am not into scary things and don’t do much frightening stuff with my preschool students, this version of the experiment produces a house that bats and spiders might like to inhabit. And here’s where the creative element kicks into high gear.

Draw the outline of a house on a paper towel section with a black nonpermanent felt pen. Trim the edges with scissors. Then add a thin line of black to the bottom of the house with the felt pen. Pour a little water with a bit of salt added into an ice cream pail. Position the paper towel so it reaches the bottom of the pail but does not slide in. Watch the immediate results. Then check back periodically to note more color changes.

This easy-to-do felt pen chromatography experiment has stunning results.

_______

When the colors have finished spreading, take the paper towel out of the pail, and dry it flat.

_______

Tip: Choose nonwashable felt pens for this experiment, as washable felt pens do not work well.

_______

The color on my paper towel chromatogram stopped just short of the top of the house. I decided to wet the top a bit so the color filled in completely. That made the design ready to be a placemat for pumpkins, bats, and spiders.

Try this easy-to-do felt pen chromatography "scary house" experiment. It has possibilities for art and imaginaive play.

_______

Two Felt Pen Chromatography Experiment

Try this easy felt pen chromatography experiment using a permanent and nonpermanent felt pen.

_______

Using both permanent and nonpermanent black felt pens produces nice results too. For this second version, draw the house on the paper towel with a black permanent felt pen. Then fill in the thin line of color at the bottom with a nonpermanent felt pen. Finish the experiment with the same process as above.

As with the first project, the resulting colors did not spread to the very top of the paper towel house. So I wet the top of this chromatogram too. The color record looks like a house on fire to me, so adding people, pets, firefighters, and orange, black, and clear gems creates another imaginative play invitation.

_______

Interpreting The Felt Pen Chromatography Experiment

The Merriam-Webster dictionary defines chromatography as “a process in which a chemical mixture carried by a liquid or gas is separated into components as a result of differential distribution of the solutes as they flow around or over a stationary liquid or solid phase.”

Although each felt pen appears to be just one color, the hues are actually made up of different chemicals called pigments. As saltwater seeps up stationary paper towels, the pigments move up with it. New colors appear because some pigments travel faster than others, and certain colors are less soluble and/or adhere to the paper towel more.

Each color-infused paper towel is called a chromatogram, a graphic record of the separation of colors into different pigments by chromatography.

Chinese New Year Sensory Play

January 14, 2021 by Annette Kaminsky Leave a Comment

Chinese New Year sensory tub with red and gold accessories in a dyed chickpea base.

Have you ever dyed chickpeas? I finally gave it a try, and it is soooo addicting! I made the first batch red to use for Chinese New Year sensory play.

In experimenting, I thought the chickpeas looked nice in a combination of dark red, speckled red, and natural hues. All deep red chickpeas seemed overpowering in the sensory tub.

Chickpeas dyed with varying amounts of red acrylic paint.

How To Dye Chickpeas

A quick and easy way to dye chickpeas is with acrylic craft paint.

Supplies to collect:

large bag of chickpeas

red acrylic craft paint

measuring cup

tablespoon

large sandwich bags

plates or trays

Scoop one cup of chickpeas into a large sandwich bag. Add a tablespoon of red acrylic craft paint. Seal the bag well and knead the chickpeas for a few minutes until they are covered in paint.

Open the bag and set it on a table. After ten minutes, pour the chickpeas onto a tray or plate. They will be completely dry in another ten minutes.

Chickpeas dyed with red acrylic paint for sensory play.

To get a speckled paint look, add half a tablespoon of paint to one cup of bagged chickpeas and knead well. Repeat the drying process.

Then color a cup of chickpeas with one-quarter tablespoon paint.

Leave some chickpeas undyed. This will give you four color varieties to add to a tub or bin for Chinese New Year sensory play.

To have enough chickpeas for a group sensory tub, dye more of them!

Note: Acrylic paint washes off hands, tables, dishware and cutlery easily. If it spatters onto your clothes, wipe the paint off with a wet cloth before washing.

Color Explosion Science Experiment

January 1, 2021 by Annette Kaminsky Leave a Comment

This dramatic color explosion science experiment is one of the simplest ones you will find. It uses ingredients you probably have in your home, is easy to set up, and shows stunning, instant results.

Supplies To Collect

serving tray

milk

food coloring (1 – 4 colors)

liquid dish soap

Kitchen supplies to carry out the color explosion milk experiment.

Conducting The Experiment

Pour a thin layer of milk into a serving tray placed on a table. I use an inexpensive 12-inch x 12-inch tree-shaped vegetable tray to add interest to the experiment. About three cups of milk will provide a nice layer in a serving tray this size.

Squeeze drops of food coloring in different parts of the tray. Use one, two, three, or even four colors. Primary colors work well.

Squirt a little dish soap in a few color pools.

Pools of food coloring in the color explosion milk experiment.

The food coloring immediately explodes to the tray edges, blending and making new colors.

Try adding a bit more food coloring, and one more squirt of dish soap. I add a little more blue, red, and yellow to the bottom right section because most of the color has moved to other areas of the tray. I squirt a tad more soap on top. There isn’t a noticeable change right away. In fact, after the initial color burst, nothing much seems to happen.

A second dose of food coloring and dish detergent are added in this color explosion milk experiment.

But wait! The experiment doesn’t end here. Leave the tray on the table undisturbed, and check back a few times over the next half-hour. The food coloring slowly moves through the milk and fills the tray.

Each time you look, new color designs are visible on the surface of the milk.
