Dandelion Sensory Tray

June 3, 2025 by Annette Kaminsky Leave a Comment

_______

With their cheery, bright color and ability to grow profusely in many different places, dandelions are super noticeable during the spring, summer, and fall seasons. All parts of dandelions are safe for handling and are edible, so the weedy flower is suitable for many educational activities.

_______

Young children delight in an early spring sighting of a field of dandelions, and the first thing they often excitedly do is make a bouquet of fluffy yellow flowers for their mom or teacher. After the petals fall off, a puffball forms on each plant, which children love to blow. This dandelion sensory tray allows early learners to explore the fast-growing, nutritious plant in another way.

_______

Supplies to Collect

_______

Since dandelions grow on lawns, in parks, and in many other environments, collecting them for a flower nature sensory tray is quick and easy. Gather a bunch of dandelion flowers and leaves from an area where no pesticides have been used. Include large plants if available. As shown in many of my other nature sensory bins, the following supplies make suitable accessories:

non-breakable vases or storage jars
pitchers with water
mortar and pestle sets
baking tins
spoons
scissors
small rocks

_______

Preparing the Dandelion Sensory Tray

Sensory bins are often one of the most effortless play invitations to offer, and this dandelion sensory tray is no exception.

First, set dandelions in small non-breakable vases or storage jars with water added.

Note: Wash the dandelions first if you have children participating who may put them in their mouths.

_______

Next, add two or more pitchers filled with cool water.

Then arrange place settings with baking tins and spoons.

Add a few mortar and pestle sets, and two or more pairs of scissors.

Lastly, sprinkle small stones and more dandelions around the bin. The tray is now ready for participants to investigate.

_______

Exploring the Dandelion Sensory Tray

_______

Children welcome sensory experiences of any kind, and this dandelion play invitation is sure to delight. The flower-filled tray offers the following benefits:

Smelling fresh dandelions exercises the sense of smell.

Bergenia Flower Sensory Bin

May 31, 2025 by Annette Kaminsky Leave a Comment

_______

Bergenia plants are easy to grow, and the beautiful bell-shaped flowers pop up in early spring. Before the dainty blooms die, consider using them in a sensory bin. The bell-shaped flowers and glossy evergreen leaves offer a unique sensory experience in this Bergenia flower nature bin.

_______

Before including it in a sensory play activity, it’s always good to check if a plant is toxic. I was happy to learn that NO part of the Bergenia plant is toxic for humans to touch or consume. The plant is also non-toxic to dogs, cats, and horses.

_______

Supplies To Collect

———-

Gather the following supplies for this flower-themed sensory bin:

Bergenia flowers, stems, and leaves
small rocks
twigs
mortar and pestle
bowls
spoons
scissors
large sensory tray

_______

Preparing the Bergenia Flower Nature Bin

———-

The setup for this bloom-themed sensory bin is super simple. If offering the bin to a group, add place settings with bowls, spoons, mortar and pestles, and scissors to a large sensory bin. Active world trays are a great choice for the bin.

Next, place a non-breakable pitcher or vase with water and Bergenia flowers in the center and spread the large glossy leaves around it.

Then set in twigs and small rocks. The bin is now ready to investigate.

Exploring the Bergenia Flower Sensory Bin

Invite participants to smell, feel, cut, mix, and grind the supplies in the sensory bin.

Explain that the Bergenia plant is also called “elephant ears” (because of the shape of the big, waxy leaves), or “pigsqueak” (because of the sound two leaves make when rubbed together.)

———-

Encourage children to rub two leathery Bergenia leaves together to make pigsqueak sounds.

Don’t be surprised if your little charges describe the leaves as being lettuce, and call the stems rhubarb, as this plant bears a resemblance to both.

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.

_______

Follow me on Pinterest for more early learning ideas.

_______

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.

Airplane Rice Sensory Bin

May 16, 2025 by Annette Kaminsky Leave a Comment

_______

This airplane rice sensory bin is easy to set up and pleasing to the eye. Putting it together is the perfect opportunity to practice how to dye rice in gorgeous blue hues.

_______

How to Dye Rice

_____

The process of dying rice is super simple and very satisfying! Gather the following supplies:

white rice
blue food coloring
vinegar
measuring cup
closable sandwich bags
teaspoon
parchment paper
large tray

_______

The Rice Dyeing Process

Dyeing rice is a quick process as rice doesn’t need much drying time. I feature basmati rice for the task, but any kind of white rice will work.

The first step in dyeing the grain is to measure one cup of rice into a closable sandwich bag.

_______

Next, drop in a teaspoon of vinegar.

Afterward, add three generous drops of blue or turquoise food coloring.

Seal the bag and shake and squeeze the contents until the blue color distributes evenly.
Note: An alternative to this method is to add a few teaspoons of vinegar to a jar and stir in the food coloring. Then spoon a teaspoon of colored vinegar into the rice-filled sandwich bag.

If the blue shade of the rice isn’t as dark as you would like, simply add a little more food coloring and vinegar to the bag and shake it some more.

_______

Lastly, spread the colored rice on a large serving tray covered with a sheet of parchment paper and leave it to dry for about twenty minutes. If you do not have parchment paper, just spread the rice on the tray. Any excess food color should wipe off pretty easily with a wet cloth.

The closable sandwich bag is reusable, and more batches of rice can be colored in it.

To add variety when dying multiple batches of rice, add a little more vinegar and food coloring to some bags. The mix of lighter and darker hues will add interest to a sensory bin. Using blue and turquoise food colors in different batches also adds contrast.

This activity is perfect for children to participate in, and it is bound to be a hit. Give each child a closable sandwich bag to measure in rice and color it. Or offer them a plastic storage container with a lid to dye the rice. As the ingredients are mixed, the container makes a shaker, adding a musical experience to the activity.

_______

The Airplane Rice Sensory Bin

_______

Putting together the airplane rice sensory bin is as easy as dying the rice. Simply pour the rice into a small storage bin. Add a few airplane figurines and some cotton balls for clouds. Or instead of the figurines, add popsicle stick or mini paper planes.

Salt Painting Earth Art

The first planet to create is our Earth as seen from outer space. Complete this salty art activity over two days.

Day One:

Protect an art table with a washable or disposable table cover.

Cut out a circle measuring 18 cm/7 inches from 8 ½ x 11-inch or 9 x 12-inch cardstock paper.

Pour white glue into a small container or paint pot.

Set the sturdy paper circle, pot with white glue, glue paddle, and disposable plate on the prepared art table.

Dip the glue paddle into the white adhesive and spread it on the circle in shapes of land forms.

_______

Using a teaspoon, generously sprinkle salt over areas of the circle that contain glue.

Tip the circle sideways over a disposable plate and shake off excess salt. (The leftover spice can be used for more salt painting planet art projects.)

Let the gluey circle dry overnight.

_______

Day Two:

Cover an art table with a washable table cover.

Prepare the watercolor paints: Mix a few drops of blue food coloring into a paint pot containing water and a few drops of green food coloring into a second water-filled pot. Or mix a lighter and darker hue in each color for more variety.

_______

Set the raised salt circle on the art table with two hues of green food coloring. Add an eye dropper or pipette to each pot.

Using the droppers, carefully drip paint onto the salt-covered areas of the circle.

_______

Then, with a paintbrush, carefully brush blue watercolor paint around the raised salt land forms to represent water.

_______

Set the painted art project aside to dry.

The earth art looks stunning adhered with a glue stick or glue gun to a black or dark blue 8 ½ x 11-inch or 9 x 12-inch cardstock or construction paper background. Displayed in a group, this salt painting planet art project looks stunning.

_______

Salt Painting Jupiter Art

_______

Jupiter also looks amazing in a salt painting planet art activity. To create planet Jupiter with this art technique, spread the glue in a stripy design to show Jupiter’s banded, cloud-covered look. Sprinkle on salt and shake it off next. After the spice-covered glue dries, drip red and yellow food coloring paint onto the raised salt areas. Then, carefully brush orange food coloring paint (or orange liquid watercolor paint diluted with water) between the raised salt areas for contrast.

_______

As with the salt painting planet Earth project, a group of arty Jupiter planets looks stunning when displayed on dark cardstock paper backgrounds.

_______

The salt painting art with an Earth theme is a great activity for Earth Day. Both art projects are welcome additions for a space theme.
