1. Capillary Action Experiment Using Flowers 

This experiment is colorful, a lot of fun to do, and allows children to learn about the scientific phenomenon of capillary action.

To perform this experiment, you will need some mason jars, water, flowers (preferably carnations), and liquid food coloring. You can use whatever color you like; however, vibrant and colorful ones just seem more pleasing.

First off, fill the mason jars with six ounces of water and put the food coloring in each jar. Now, don’t be shy to put in enough food coloring because if you don’t put in a good amount, you may not be able to notice the results. 

Then, take your flowers, cut the stem at an angle, and place them in the jars. These need to be placed someplace sunny, and in about three days, you will notice distinct colors starting to appear on the flowers.

The flowers change colors because they absorb the water by capillary action, much like they do when placed in soil.

2. Color Explosions in a Jar

If you have a child who likes color and fireworks, this might be an excellent project to work on with him/her.

It is incredibly simple, and most of what you need for this would already be present at your house, which makes it convenient. To work on this project, you only need a jar, oil, water, and some food coloring. 

Now, first, fill 3/4th of your glass with warm water, and in a separate bowl, mix three to four spoons of oils and mix it with drops of different colors of food coloring. Then, go ahead and pour the oil mixture into the jar of water.

At this point, you will notice that the food coloring will sink from the oil into the water, expand, and start mixing in with the different colors. This will appear like tiny explosions or fireworks in the jar and is quite pretty to look at.

The reason why this happens is the difference in density of the two liquids. Oil is denser than water, and it floats on the top, whereas the food coloring isn’t soluble in oil. The droplets sink in the water and start dissolving.

3. Coffee Filter Chromatography 

Chromatography has several types and is a widely used technique in labs. Some might feel it’s too advanced; however, if done the right way, it might grab the kid’s attention and teach them a thing or two.

It is essentially a separation technique that allows the observer to see the different pigments present in a mixture. 

For this experiment, you will need a marker, coffee filters, food coloring, small glasses, and water. Most of this is pretty much present in your house.

First, using the marker, draw a circle around the center of the coffee filter. Then, make it into a cone by folding it in half and then folding it in half again.

Add some food coloring to a shallow glass of water and place the filter cone in the water. Make sure you don’t get the marker ring wet. You will notice the colors flow up the paper in a beautiful manner.

This can be a great opportunity to teach children about molecules and how chromatography is useful in the lab.

4. Learning About Magnetism While Fishing

All kids seem to be fascinated by magnets and love playing with them. Magnets can be used to introduce children to science and be a great starting point to later introduce them to compasses, geology, and several other uses of magnets.

In this experiment, your children will learn the difference between magnetic and nonmagnetic materials, all while fishing at home!

For this experiment, you need an assortment of iron objects (nuts, paper clips, etc.), some nonmagnetic objects (rubber bands, buttons, etc.), and a bin with a little bit of water, which will only serve as a sensory element.

To make the fishing stick, you will simply need to tie a magnet using a string to a pencil. 

After you’ve set up the experiment comes the fun part! Let the children fish using the stick and collect the objects in a pile. Then, explain that the leftover objects in the pile are the nonmagnetic ones.

5. Learning About Effervescence 

This is one of the coolest and most engaging experiments you can perform with a kid. Through this experiment, they can be introduced to the interesting phenomenon of effervescence, and most of what’s used in it is already available in most homes.

For this experiment, you need clear carbonated soda, one tablespoon salt, a spoon, a small jar, and food coloring. Fill the small jar about halfway with carbonated soda.
Then, go ahead and add the food coloring of your choice to it and stir. Finally, add salt to this and observe what happens next. 

You will notice bubbles starting to form and coming to the surface, which is super cool to witness. This happens due to the salt pushing the carbon dioxide to the surface.

6. Learn About the Deep Blue Ocean

You can enjoy doing a crafty project with your kids and teach them all about the different layers of the ocean.

It can be made even more interesting by talking about how far the light travels in water, what animals live in each layer, etc.

You will need five small containers, food coloring (blue, green, and red), water, ocean animal figures, paper, and a marker to make this project. 

Write down the name of each ocean layer and label each jar with it. If you are using animal figures, then place them in the jar before adding the water.

Make sure to search which creature lives in which part of the ocean layer. Fill each container with water and add food coloring. For six ounces of water, add:

Sunlight Zone: Touch a toothpick with the blue food coloring and dip it in the container.

Twilight Zone: one drop of blue food coloring

Midnight Zone: two drops of blue food coloring

Abyss: four drops of blue food coloring

Trenches: five drops of blue, two drops of green, and one drop of red food coloring

7. Icy Lanterns

This activity is perfect for the winters when it’s cold and chilly out.

Building ice lanterns can be a great engineering challenge for kids as they decide the base of their project and how it will go about.

It truly is very fun and gives a beautiful outcome. 

For this experiment, you will need a battery-operated candle, large and small plastic cups, decorative pieces like pom poms, beads, pipe cleaners, tinsel, etc., food coloring, and a freezer. 

Firstly, take the pipe cleaners and twist them so much so that they can spiral along with the large cup and act as a balancing medium for your decorative items. Then, carefully balance the beads and other things on them. 

Next, slide the small cup inside the larger cup and secure it with tape.
Finally, add water between the cups such that it only goes in the large cup.

Add a few drops of preferred food coloring. Put this in the freezer for five hours or until completely frozen.

Ten frames can be of great aid in providing a strong number sense to children and easily demonstrate numbers less than or equals to ten.

If you have a little one who’s working on a ten frame, they will enjoy a penguin-themed one a lot.

There are several penguin-themed ten frame printable worksheets available online. 
For this activity, you need some penguin erasers, penguin ten frame worksheets, and a dry erase marker or crayon if you choose to laminate them.

Print as many as you like and write a number on them. Then, instruct the children to use the erasers and count up to the number.

This will aid in bridging the gap between theoretical counting and physical counting. You can also teach them simple subtraction and addition using the same method.

10. Send Secret Messages Using Cranberry Juice

This is perhaps one of the coolest experiments the kids can perform using regular things around the house.

Have the kids write secret messages to each other and decode them using cranberry juice.

It seems magical yet is pure science. You will need a small pot, cranberry juice, water, cranberry sauce, paintbrushes, baking soda, and white paper for this experiment. 

First, mix the cranberry sauce and juice in the pot and bring it to a boil over medium heat while stirring in between. Then, to make the invisible ink, mix 1/3rd cup of hot water and four tbsp of baking soda.

Using the baking soda mixture and a paintbrush, write a message on paper and dry it.
After letting the cranberry juice cool down, dip a paintbrush in cranberry juice and paint over the dried messages to reveal the secret picture. 

Cranberry juice is acidic, whereas the baking soda mixture is basic. Even though the baking soda mixture dried clear when it interacted with the acidic mixture, a color change from red to blue was observed, and the secret message was revealed.
