Easy Chemistry Experiments For Elementary Students – When I think back to my own childhood and school days, I don’t remember any chemistry experiments until middle school, which is a shame because there are so many wonderful, easy visual chemistry experiments for kids that can be done at home or at school. small children
I struggled a bit when we tried this because the reaction happens so fast, but Steve Spangler has a nifty method where he traps the vinegar in another small bag, which you have to pop to start the reaction.
Easy Chemistry Experiments For Elementary Students
This is a very simple demonstration or experiment that has never failed me, and all you need is a small neck, a balloon, and a container of either Alka Seltzer or an effervescent vitamin tablet. An alka seltzer or vitamin tablet reacts with water to release carbon dioxide bubbles that fill the jar and inflate the balloon.

This oil, water and food coloring exploration table is brilliant for even toddlers. Try a more structured approach for older kids, they can measure the amount of vinegar and baking soda needed to spread the reaction over the top of the beaker, or try adding a small amount of colored water to the oil.
If you don’t want to make as many layers as we have, why not try this smaller version and try to find an object to float on each layer.
Bubble Double Doo This lemon volcano is a great alternative to a traditional volcano and it’s easy because the lemons are already acidic.
Test the ph of vinegar and baking soda with a red cabbage indicator. What happens if you blow into the indicator?

Watching colors melt from Skittles or M&Ms melt into water is a great, quick, visual activity.
Who doesn’t love a giant bubble? Red Ted Art makes bubbles easy in this great video. Remember that the longer they leave the mixture the better, so allow plenty of time.
The infamous Coke and Mento reaction is very easy to watch and very impressive. Try comparing geyser sizes using diet and sugar-laden colas or using different types of carbonated drinks.
Fun at home with kids makes elephant toothpaste super easy, but be careful with hydrogen peroxide and be careful.

Film canister rockets are simple, inexpensive and great fun. All you need is a box of film, a vitamin tablet and some water. Experiment with different amounts of water and pellets to find the most explosive combination.

Everything we eat and drink is acidic and the things we use for cleaning are basic. This is because the basic substances have an unpleasant taste, but generally the cleaning agent needs the basic to remove dirt and grease.
Acids are a very common group of chemical compounds, many of which occur naturally. Acids can be strong or weak.
Citric acid, which occurs naturally in lemons, is a weak acid. Hydrochloric acid (used for soldering) and sulfuric acid (battery acid) are very strong acids.

Bases (often called alkalis) are another group of chemical compounds that have different chemical properties than acids. When bases and acids are added together, they will neutralize each other’s properties.
We describe whether things are acidic, basic, or neutral using a scale called the pH scale. The pH scale ranges from zero to 14. A substance with a pH of:
Acids and bases can be detected by a group of chemical compounds known as acid-base indicators. One of the first naturally occurring indicators known was a lichen called litmus. (Lichens are plant-like growths often found on rocks and tree bark.) Litmus turns red in the presence of acid or blue with a base.
Most of the indicators used to detect acids and bases are man-made. However, many plant pigments, such as the red cabbage you used, contain chemicals that act as acid-base indicators.

Learn more about gas by making a drink fountain using lollies/cookies. What a great way to learn more about chemistry!
Until you open the bottle, the gas is mostly dissolved in the liquid and cannot expand to form bubbles, which gas will do if it is not under pressure.
If you shake the bottle and open it, the gas escapes with the whoosh, taking some of the soft drink with it. Adding anything to a soft drink causes more bubbles to form and escape.
Easy Chemistry Experiments You Can Do At Home
Lolli gives surface very quickly, which means gas bubbles form very quickly in large numbers.
When you look into a soft drink glass, there are usually some streams of bubbles coming from specific points on the glass where the surface is uneven.
Sometimes you will see a stream of bubbles coming from the center and if you look closely you can often see a piece of dust with bubbles coming from the end.
As the lollipop melts, it creates hundreds of nucleation points which are tiny holes on the surface of the lollipop where more carbon dioxide bubbles can form.

When all this gas is released, it throws everything in the bottle into the sky in an explosion of incredible soft drink.
Follow these instructions to make your own bath bombs and learn about science while having fun in the bath!
When bath bombs dissolve in water, there is a chemical reaction between citric acid and sodium bicarbonate. The result is called sodium citrate. During the reaction, carbon dioxide is released. This causes the ‘fizzing’ you see, just like sparkling water.
Sweet almond oil is released during this reaction. It will create a thin layer on your skin that can help hydrate/moisturize it. Lavender oil is for fragrance.

You have just created an acid-base reaction in your mouth. When you combine an acid (acidic acid in this activity) and an alkaline (bicarbonate of soda) with saliva, they mix together to form gas in the form of many small bubbles.
This is called an acid-base reaction and is what gives syrup its fizz. You actually feel the sensation of carbon dioxide bubbles on your tongue. These are the same bubbles found in fizzy drinks.
Icing sugar is needed to add sweetness because citric acid and bicarbonate of soda are quite tart. Citric acid is one of the acids found in lemons, oranges and limes. That is why they are called ‘citrus fruits’.
Another acid in lemons and other acidic fruits is called ascorbic acid. This is commonly known as vitamin C. The jelly crystals just add flavor.
Chemistry Experiments And Activities For Kids
Vinegar, or diluted acetic acid, ‘eats’ the calcium carbonate from the eggshell, leaving only the egg’s inner membrane or back skin. As calcium carbonate is responsible for making the shell hard, vinegar-soaked eggs tend to feel soft and rubbery.
When calcium carbonate (eggshell) and acetic acid (vinegar) combine, a chemical reaction occurs and carbon dioxide is released. That’s why you see bubbles.
The chemical reaction continues for about a day until all the calcium carbonate in the egg is used up. Calcium carbonate is found in eggshells, seashells, limestone and many other materials.

Limestone is a sedimentary rock composed mainly of calcium carbonate. Usually it is white, but it can be colored by impurities; Iron oxide makes it brown, yellow or red and carbon makes it blue, black or gray. Texture varies from coarse to fine.
Most limestone forms over thousands of years from the skeletons of marine invertebrates. Important varieties of limestone include marl, chalk, oolite, travertine, dolomite and marble.
