The only chemistry experiments I can recall doing growing up were in advanced chemistry in high school and as a chemistry major in college, which is unfortunate because there are so many excellently visual, simple activities for excellence in science education.
We connect chemistry with lab coats, beakers, and specialty substances. Still, the truth is that school chemistry teachers can do many science activities with essential, everyday life items frequently present in your pantry.
These enjoyable and cool chemistry experiments, organized by topic, are designed to help for chemistry teachers introduce the basics to the kids.
This magic milk test is sure to become your favorite chemistry experiment. Mixing a little milk, some food coloring, and a dab of liquid soap results in strange interactions. Discover the fascinating scientific secrets of soap through this experiment, then astound your chemistry students.

Pour the following liquids into a plastic bottle to create a density lava lamp: a layer of vegetable oil, clear corn syrup, and water with a few drops of food coloring. Make sure the top of the bottle has room. Before adding an extra strength Alka seltzer pill, wait for the liquids to settle. Water and Alka seltzer react, bubbling up through the oil layer.
Add blue, red, and yellow food coloring to three transparent plastic cups. Give your kids an empty ice cube tray and pipettes to produce new colors by mixing two primary colors. Two primary colors form a new secondary color. This shows how chemical reactions occur.
Fill the bottom of the empty water bottle with a few spoonfuls of sugar for the yeast balloon experiment. Using warm water, fill the bottle to about halfway. Add yeast to the mixture. Place a balloon over the bottle opening after swirling the contents. After a while, the balloon begins to inflate and grow in size.
The baking soda and vinegar volcano is a fun project in the field of chemistry that may be used to replicate an actual volcanic eruption or as an illustration of an acid-base reaction. Baking soda (sodium bicarbonate) and vinegar (acetic acid) react chemically, producing carbon dioxide gas, which creates bubbles in the dishwashing solution.

In this simple chemistry experiment, kids fill a jar three-quarters of the way with water and add food coloring as desired. Add a tablespoon of baking soda and stir. Add a quarter cup of uncooked rice and a couple of teaspoons of white vinegar. Observe how the rice moves.

The traditional baking soda and vinegar acid-base chemistry experiment has been twisted in this science experiment using exploding baggies. Insert a folder tissue containing three tablespoons of baking soda quickly into a bag, and take a step back. Watch the bag slowly get bigger until it bursts.

Turn eggs into rubber with this simple chemistry experiment for kids. Carefully put a raw egg in a clear jar or cup. Pour enough vinegar into the cup so that the egg is completely covered. Add a few big drops of food coloring and stir the mixture gently. Over a few days, the vinegar breaks down the eggshell.

Begin by reÂmoving as much paÂper from the scratch pad of a matchÂbox as possible. IgÂnite it in a porcelain cup or plate. After that, remove the unburned remains. A thick greasy liqÂuid has accumulated at the bottom. To create white smoke, put the liquid on your fingers and rub them together.

This is a cool chemistry experiment that you can perform in your class. Baking soda produces carbon dioxide gas when heated. Similar to typical intumescent fireworks, the snake shape is created when the pressure from this gas forces the carbonate from the burning sugar out.

In this experiment, a candle is used to burn soot onto an egg, which is then submerged in water. The eggshell’s surface is covered with the soot that accumulates, and if the burnt shell is submerged in water, it turns silver. The egg appears silver because the soot deflects water and covers it with a thin layer of air that reflects light.

In this elementary school chemistry level experiment, diluted lemon juice is utilized as ink on paper. Until it is heated, the lettering is invisible, but the hidden message is revealed when it is heated. Lemon juice is an organic component that, when heated, oxidizes and turns brown.

You will divide the color black into other colors for this elementary school chemistry level activity. A coffee filter is folded in half. To form a triangle, fold twice more in half. A black washable marker is used to color the coffee filter’s tip. A little water is added to a plastic cup. Observe after inserting the coffee filter’s black end into the cup. You should see blue, green, and even red as the water separates the ink.
Pupils will use coffee filters to separate the colors of several markers in this science experiment. After seeing the outcomes, they can use the resulting coffee filters to make a bright floral craft.

In this chemistry activity, elementary school kids will adapt their finished science project into a chromatographic art piece. Younger children can make a vibrant collage, while older children might do a weaving art project.

After mixing water and cornstarch, allow the children to dip their hands into this non-Newtonian fluid, which has properties of both a solid and a liquid. Oobleck feels firm to the touch after a rapid tap because the cornstarch particles are compressed. However, slowly plunge your hand into the mixture to see what happens. Your fingers should slide in like water.
Fat molecules tend to clump together when cream is shaken. After some time, the buttermilk is left behind as the fat molecules stick together to create a lump of butter. Making butter is the ideal chemistry for kids in elementary school.
Fill four bowls with an equal amount of ice cubes each for this activity. Generously add baking soda, salt, sugar, and sand to the different bowls. After about every 15 minutes, check on your ice and take note of the varying melting levels.

Put your skittles or sweets in a white container and try to mix up the colors. Water should then be carefully poured into the container; observe what occurs. When you pour water over the skittles, the color and sugar dissolve into the water. The color then spreads through the water, making it the color of the skittle.
A straightforward STEM activity for the classroom involves making homemade slime whose color changes with temperature. The color of the slime changes at a particular temperature when heat-sensitive pigments (thermochromic pigments) are added. The thermochromic dye applied may cause the color to change at specific temperatures making this my favorite slime recipe.

Even though it sounds impossible, learning how to poke a stick through a balloon without popping it with the correct scientific knowledge is feasible. Elastic polymers found in balloons enable the balloon to stretch. The skewer is enclosed by these polymer chains, which stop the balloon from popping.
Borax crystallization is an exciting science activity. The results of letting the crystals grow are lovely, but it does require some patience. Children may practically observe changes in matter as crystals form and how molecules respond to temperature variations.
Increase your elementary school students’ attention in chemistry lectures using this hands-on crystal-growing activity, a hybrid of a craft project and a science experiment. While crystal-filled geodes naturally form over thousands of years, you can produce your crystals in a single day using materials you can find at the grocery store.
