Science Projects for Kids: States of Matter Sugar Crystals on a String

Sugar crystals on a string can be fun to watch grow and delicious to eat. When liquids evaporate into gases, they can leave material behind. That material can be very tasty, as shown by this science project for kids on states of matter. But note that this project requires adult supervision!

What You'll Need: •

Pan

•

Water

•

Stove

•

Sugar

•

Measuring spoon

•

String

•

Pencil

•

Glass

•

Scissors

•

Button

Step 1: Bring a small pan of water to a boil on the stove, and turn off the heat. Step 2: Add one tablespoon of sugar, and stir until it dissolves.

Step 3: Continue adding sugar, one tablespoon at a time, letting each tablespoonful dissolve completely before adding the next. When no more sugar will dissolve in the water, allow the saturated solution to cool. Step 4: Tie a string to the middle of a pencil, and set the pencil across the rim of a glass. Cut the string so that it just touches the bottom of the glass. Tie a button onto the bottom of the string. Step 5: Pour the cooled sugar water into the glass. Rest the pencil across the rim of the glass so that the string and button are in the solution. Step 6: Allow the glass to sit in a warm place without being disturbed for several days so that the water evaporates. As the water evaporates, it will leave sugar crystals on the string. You've just made rock candy.

Homemade Water Purifier

Try this homemade water purifier to see how suspended matter can be filtered from water. You may be surprised by how this science project for kids on states of matter works.

What You'll Need: •

Eight-inch-tall cardboard box

•

Two bowls

•

Water

•

Dirt

•

Wool yarn

Step 1: Set an eight-inch-tall cardboard box on a table. Set a bowl of clean water on top of the box. R.ELUMALAI , SGT Teacher { PUMS-Kavanoorpuducheri , Uthiramerur Block , Kancheepuram } – 9751366565 www.tnmanavan.blogspot.com

mwptpay; - 4.gUg;nghUs;fSk; gy;tif tPLfSk; KEEP READING BELOW

Step 2: Gently drop a small handful of dirt into the water. Much of the dirt will remain suspended in the water, and the water in the bowl will be discolored. Step 3: Set an empty bowl on the table right next to the cardboard box. Step 4: Twist together several one-foot strands of wool yarn to make a rope. Step 5: Put one end of this rope, or wick, into the bottom of the bowl of dirty water. Place the other end of the wick in the empty bowl. After a while, drops of clear water will drip off of the free end of the wick into the empty bowl.

What Happened? The material in your rope absorbs water and draws it from the bowl. It leaves the dirt behind, however, so the water that drips into the second bowl is clean.

Soda Pop in a Balloon

Gases can dissolve in a liquid, as this example of soda pop in a balloon shows. But they won't stay there if you release the pressure that holds them. Try this science project for kids on states of matter, and see what happens.

What You'll Need: •

Bottle of soda pop

•

Balloon

•

Watch

Step 1: Open a bottle of soda pop, and set it on a table. Step 2: Immediately slip the end of a balloon over the neck of the bottle. Pull the balloon's end well down over the bottle so that it fits tightly.

Step 3: Check on the balloon about every 10 minutes for any changes.

What Happened? Soda pop is carbonated. This means that carbon dioxide gas has been dissolved in the liquid under high pressure. Opening the bottle releases the pressure, and the carbon dioxide gas begins to escape from the liquid. The balloon trapped the carbon dioxide gas as it left the bottle, and then the gas inflated the balloon.

Cloud in a Bottle Make a little weather of your own with a cloud in a bottle. Clouds form when warm, particlerich air meets cool, moist air. This science project for kids on states of matter can help you understand just how the process works.

What You'll Need: •

Table

•

Candle

•

Match

•

Clear glass two-liter bottle

Step 1: On a cool day with little or no wind, head for your backyard and find a table. Step 2: Have a child light a candle, with help from an adult. Step 3: Turn the two-liter glass bottle upside down, and hold the candle inside the mouth of the jar for about 10 seconds. Don't use a plastic jar. The mouth of a plastic jug could melt. Step 4: Once the bottle's mouth has cooled a little, form a seal around the bottle with your mouth and blow. Once you pull your mouth away, you should see a cloud form inside the bottle -- just like in the skies above your home.

Soap Bubble Shapes

Who knew something as fun and as simple as blowing soap bubble shapes could also be an easy science project for kids on states of matter? See what shapes and sizes of bubbles your kids can blow while they learn about surface tension.

What You'll Need: •

Dish-washing liquid

•

Measuring cup and spoon

•

Glycerin

•

Water

•

Large container

•

Dishpan

•

Pipe cleaners

•

Plastic soda pop ring

•

Scissors

•

Stapler

•

Wooden sticks

Step 1: Add 1/2 cup of dish-washing liquid and two teaspoons of glycerin to 1/2 gallon of water in a large container. Step 2: Mix the materials together, and let them sit overnight. Step 3: The next day, pour the mixture into a plastic dishpan outdoors. Step 4: Shape pipe cleaners into circles of different sizes.

Step 5: Cut a circle of plastic from a soda pop ring, and staple it to a wooden stick. Step 6: Dip these devices into the bubble solution, and gently blow through the circles to make bubbles. Circles of different sizes will make bubbles of different sizes.

Stretch the Surface of Water

It may be hard to believe, but you can stretch the surface of water. See just how far you can stretch it in this science project for kids on states of matter.

What You'll Need: •

Small plastic cup

•

Water

•

Eyedropper

Step 1: Fill a small plastic cup all the way to the top with water. Step 2: Hold an eyedropper filled with water close to the surface of the water in the plastic cup, and gently release the water drop by drop. How many drops can you add to the plastic cup after it is "full"? Can you see that the water level actually rises above the top of the cup? Water molecules attract one another strongly so that the water holds together.
