Oobleck is a classic science experiment that’s perfect for entertaining kids and adults alike. If you haven’t seen it in action, it’s pretty cool stuff and you’ll soon have your hands covered in it, happily making a mess that can be washed away with water.

Oblique is a non-Newtonian fluid. That is, it behaves like a liquid when poured, but like a solid when a force acts on it. You can grab it and then it will fly out of your hand. Make enough Ooblecks and you can even walk on them!

Welcome To The Krazy Kingdom: 6th Grade Science Fair

Where a green colored object falls from the Oblique sky and wreaks havoc in the kingdom. Here the Oobleck will be turned into a bowl and will likely cause chaos, but only because you can run around playing with it.

Start with water in a bowl and start adding cornstarch to it. You can use a spoon at first, but soon you will switch to using your hands to stir it.

When you’re about to add 1.5 cups of cornstarch, start adding it slowly and mixing it in with your hands. The goal is to achieve a consistency where the Oobleck reaches a liquid state and is still solid.

Sometimes you need more cornstarch. If so, continue adding more than the initial 1.5 cups. If it is too much, add a little water. You have to play around with it to see what feels weird.

Easy Stem Activities For Kids!

Now that the Oobleck is ready, it’s time to add color. We saved this step for later because mixing in food coloring is an interesting challenge. You need to mix the Oobleck slowly to mix it well.

Do not continue playing with Oobleck. That’s what it’s all about and there are tons of recipes you can try. Here is a short list:

Put it on the subwoofer and play some low frequencies at high volume (hard to set up, but worth it) Here are 8 science experiments for kids during the school holidays. This experience is great for older kids, or with the help of mom or dad. They can be made at home with ingredients you already have.

The things we eat and drink are acidic and the things we use to clean are basic. This is because the base material has an unpleasant taste, but the cleaning agent usually needs a base 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 a base and an acid are added together, they neutralize each other’s properties.

We use a scale called the pH scale to describe whether something is acidic, basic or neutral. The pH scale ranges from zero to 14. Substances whose pH is:

Acids and bases can be detected by a group of chemical compounds called acid-base indicators. One of the first natural indicators was a lichen called litmus. (Lichens grow like plants, often found on rocks and tree bark.) Litmus turns red in the presence of acids or blue in the presence of bases.

Most indicators used today to detect acids and bases are man-made. However, many plant pigments, such as the red cabbage you eat, contain chemicals that act as acid-base indicators.

Learn more about gas by making a soft drink fountain using candy/sweets. A cute way to learn more about chemistry!

Until you open the bottle, the gas is mostly dissolved in the liquid and cannot expand into bubbles, which gas would do if it wasn’t under pressure.

If you shake the bottle and then open it, the gas comes out with a sigh, taking some soft drink with it. Adding anything to soft drinks allows more bubbles to form and come out.

Lulls provide a very fast surface area, which means that a large number of gas bubbles form very quickly.

When you look at a glass of soft drink, there is usually some stream of foam coming from a certain point on the glass where the surface is uneven.

Sometimes you see a stream of bubbles coming from the middle 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 the entire contents of the bottle into the sky, in an incredible soft drink explosion.

Follow these instructions to make your own bath bomb and learn about science while having fun in the bath!

When bath bombs dissolve in water, a chemical reaction occurs between citric acid and sodium bicarbonate. The result is called sodium citrate. Carbon dioxide is released during the reaction. This causes the ‘sound’ you see, just like carbonated water.

Sweet almond oil is released during this reaction. This 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 mix acid (citric acid in this activity) and alkali (bicarbonate of soda) with saliva, they combine to form gas in the form of many small bubbles.

This is called an acidic reaction and is what gives the syrup its zing. You can actually feel the carbon dioxide bubbles on your tongue. This is the same foam found in fizzy drinks.

Icing sugar is needed to add sweetness because citric acid and bicarbonate of soda are quite acidic. Citric acid is one of the acids found in lemons, oranges and limes. That is why they are called ‘citric fruits’.

Another acid found in lemons and other citrus fruits is called ascorbic acid. It is commonly known as vitamin C. Jelly crystals only add flavor.

Vinegar, or dilute acetic acid, ‘eats’ the calcium carbonate in the eggshell, leaving only the egg’s inner membrane, or shell, behind. Since calcium carbonate is responsible for making the hard shell, eggs soaked in vinegar feel soft and rubbery.

When calcium carbonate (eggshell) and acetic acid (vinegar) combine, a chemical reaction occurs and carbon dioxide gas 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 mostly of calcium carbonate. It is usually white, but may be colored by impurities. Iron oxide makes it brown, yellow or red and carbon makes it blue, black or grey. The texture varies from coarse to fine.

Most limestone is formed over thousands of years from the skeletons of marine invertebrates. The main types of limestone include marl, chalk, oolite, travertine, dolomite and marble.

Acid rain causes reactions in this activity. One type of acid rain can be caused by air pollution caused by the burning of fuels containing sulfur atoms, which burn to produce sulfur dioxide gas.

When sulfur dioxide mixes with rain, it turns into weak sulfuric acid. When acid rain hits limestone, it slowly separates it, like an eggshell. People use limestone in buildings and sculptures.

If you collect a sample of a small rock and put it in vinegar, you can see bubbles appear, as happens with eggs. The presence of foam indicates that calcium carbonate may be present in the sample.

Calcium carbonate reacts with acid to produce carbon dioxide gas, which we see as bubbles. This is called the ‘acid test’. The ‘acid test’ is one of many tests used by geologists to identify rock samples.
