Sugar and water experiment

Sugar is one of the chemicals you have in your home in relatively pure form. You can use sugar as a material for chemistry experiments. The projects range from safe-enough-to-eat because sugar is edible to adult-supervision-only because sugar is combustible.

Here are some of the things you can do with sugar. One tasty way to learn about the properties of sugar is to crystallize it. Colored and flavored sugar crystals are called rock candy. Consider how the covalent bonds in sucrose affect the way it dissolves in water to make the crystal solution.

How does the crystal form of rock candy differ from how sugar crystals look under a magnifying glass? Fans of the tv show Breaking Bad can adapt the regular sugar crystal recipe to make chemist Walter White's classic blue crystal product.

One way to layer liquids is to pour a light liquid over one that is denser. For example, you can simply demonstrate oil is lighter than water this way and also that oil and water are immiscible.

But, you don't have to use different chemicals to layer them. You can simply make the bottom layers more concentrated than the top ones. Try it yourself using colored sugar solutions. Sugar is a carbohydratewhich means it's a form of fuel in your body.

It's also a fuel in chemical reactions. For example, you can use sugar to make homemade black snack fireworks. These fireworks don't explode—they puff out columns of black ash. Chemistry is at the heart of any form of pyrotechnic. If the black snakes whetted your appetite for more fire fun, try making homemade smoke bombs. You only need two ingredients to experiment with these: sugar and potassium nitrate.

Combustion is a chemical reaction. While it's usually initiated by applying a heat source, such as a match, it's possible to start a fire without adding thermal energy. For example, mix sugar with potassium chlorate and see what happens if a drop of sulfuric acid is added!

Updated April 30, Younger kids can learn about different flavors and learn the vocabulary to describe them, while older children can figure out for themselves which parts of her tongue are sensitive to which tastes.

Note: Mapping tastebuds will require placing toothpicks all over a child's tongue, including the back of it. This can trigger a gag reflex in some people. Share Flipboard Email. Amanda Morin. Amanda Morin is a freelance writer specializing in child development, parenting, and education.

Updated February 18, Taste-related vocabulary Taste bud mapping. Ask the child to stick their tongue out in front of a mirror. Then, ask them to make a good guess about how the tastes and taste buds work. Set the paper aside.

Set up four plastic cups, each on top of a piece of paper. Pour a little lemon juice sour into the one cup, and a little tonic water bitter into another. Mix up sugar water sweet and salt water salty for the last two cups.

Label each piece of paper with the name of the liquid in the cup—not with the taste. Give the child some toothpicks and have them dip on in one of the cups. Ask them to place the stick on the tip of their tongue. Do they taste anything? What does it taste like? Dip again and repeat on the sides, flat surface, and back of the tongue. Once the child recognizes the taste and where on their tongue the taste is the strongest, have them write the name of the taste—not the liquid—in the corresponding space on the drawing.

If they want to draw taste buds and color in the tongue, have them do that, too.There are many elementary science projects and experiments that can be easily carried out using salt, sugar, water and ice cubes or some combination of these supplies. Experiments of this nature are suitable for elementary school children as an introduction to chemistry, specifically solutions, solutes and solvents.

The starting point for any experiment is a hypothesis: speculating an answer to the question you hope to answer with your experiment. Your hypothesis will be a definitive statement, the validity of which you will test in the experiment. Before you start, you should make a guess about what effect salt or sugar will have on the melting rate of ice.

Sprinkle one with a small amount of salt, one with the same amount of sugar, and leave the third as it is. Time how long it takes for each ice cube to dissolve. This experiment is suitable for early elementary students and will test the solubility of salt and sugar.

Fill two small, clear plastic cups halfway with water. Add a tablespoon of salt to one and sugar to the other. Time how long it takes each substance to completely dissolve in the water.

Sugar is more soluble and therefore should dissolve faster than the salt.

What Happens When You Mix Water and Sugar?

In this experiment, you will test how different solutes affect the temperature at which water freezes. Fill three small cups half-full with water. Add a tablespoon of salt to one and a tablespoon of sugar to another; stir until they are dissolved. Do not add anything to the third cup; it is your control. Place the three cups in the freezer, which should be set exactly to the freezing point of water: 0 degrees Celsius or 32 Fahrenheit.

Make sure each cup is clearly marked. Check your solutions every 15 minutes for two hours. You should find that the control cup has frozen entirely.

The salt and sugar water cups will not have frozen. Try lowering the temperature of your freezer gradually until the sugar water freezes. You will find that the salt water will be the last to freeze: this is because adding any soluble to water will lower its freezing point, but salt is more effective at this than sugar. This experiment is a good introduction to chemistry, as well as to lead into lessons about sea water and geography. In this experiment, you will dissolve salt into a small tub of water, while maintaining a second tub of fresh water.

Use two identical objects, one in each tub, to determine which solution allows objects to float better.

You should find that, with enough salt added, the salt water will better support the object and allow it to float better. Jennifer Reynolds is a professional writer covering crafting, electronics and entertainment topics.

She graduated in with a Bachelor of Arts in professional writing from York University. In this experiment, you will need three ice cubes of the same size. You should find that the ice cube sprinkled with salt will melt the fastest of the three.

About the Author. Copyright Leaf Group Ltd.Mix the yeast and sugar into the warm water and stir. I noticed that N was sniffing the concoction and asked her what it smelled like. Consider yourself warned. N wanted to feel it as it filled with air. As we went through the process, I thought of a few fun extensions for older kids or those who want to take this further.

How do you like your bread? And have you played around with yeast concoctions? I used to bake a lot of bread with my boys when they were younger pre-celiac diagnosis and they always loved my scientific explanation of why the bread rises: the yeast eats the sugar and farts. Yep, farts would be another not-so-pretty way to describe this process. Thanks for sharing your yeast experiments, Amy!

I love them, and we have to try this with maple syrup next time if I can convince my MS-adoring family to part with it first! This is the best blog for experiments!

Thanks for sharing all your great ideas. Hi Kristin, Thank you soooooo much for the kind words about Tinkerlab. And thanks for sharing us with your readers…. Hmmm…sugar, yeast and water…also known as Kilju or sugar wine! As well as CO2, yeast and sugar also produces Ethanol alcohol. Probably best not to teach the kids that part though! Point taken. What quantity of water did you use?

Comments What a great idea!! I pinned this! This is so fun! We did this today and the kids loved it.We set up an investigation to find out how the amount of sugar differs between common drinks.

We decided to calculate the amount of sugar in the full bottle or container rather than for the same amount of the drink as most people would drink a whole bottle, but as an alternative you could calculate the amount of sugar per ml or ml of each drink. Calculate how many cups of sugar you would need to drink to consume the same amount of sugar as one bottle of Ribena. We used this great balance from Learning Resources. Can you make your own balance?

This is especially true for the six solutions you made using sugar and water. By increasing the amount of sugar in the solution but keeping the amount of water constant, you create solutions that have increasing densities.

As the Sugar Rainbow reveals, a solution with a low density stacks on top of a mixture with a high density. Now supporting local bookstores via Bookshop. Facebook Twitter Instagram Tumblr. Smart videos for curious minds of all ages. Primary Menu.

Not necessarily! By dissolving different amounts of sugar in each glass of water, you change the densities, allowing the colors to stack like a rainbow! Add 1 tbsp of sugar and 2 drops of red food color to the first glass, and stir vigorously to completely dissolve the sugar.

Add 2 tbsps of sugar and 2 drops of yellow food color to the second glass, and stir completely again to dissolve. Add 3 tbsps of sugar and 2 drops of green food color to the third glass and stir. Add 4 tbsps of sugar and 2 drops of blue food color to the fourth glass. Use the syringe to transfer about half of the blue water into the empty glass. Still using the syringe, transfer half the green water into the rainbow glass.

Add it slowly on top of the blue water. It will sit on top.
