How To Make Soap With Kids

Fun Science Activity for Kid Homeschool

Experiments Bubblology
to share with their children

By Aurora Lipper

This article teaches kids about the science of bubblology and gives a handful of totally fun activities to experiment with their learning of science education at home (including castles, bubbles, light shows, and a child-in-a-bubble). It is also good for the Boy Scouts working on a badge, or for a child that science experiments love. These experiments are part of a school science program at home that I teach, and I promise that your kids will love it.

If you pour a few drops of water on a sweater or material, you will notice that the water just sit there on the surface of a ball (or oval, if the drop is large enough). Touching the soapy water ball with a finger, the ball is lost in the fabric fibers! What happened?

Soap makes water "wetter" break the surface tension of water by about two thirds. The force that keeps the water drop-shaped area called surface tension. It is the reason you can fill a glass of water in the past the edge without spread. The water becomes "wet" because no soap, no fibers can enter your clean clothes. That's why you need soap in the washer.

The soap makes the water too elastic. If you've ever tried blowing bubbles with his mouth just using spit, you know you can not get bigger, saliva fist-sized bubbles and float to completely separate in the air. The water itself is the surface tension much, too many forces holding the molecules. When you add soap to it, relax a bit and stretch. Soap makes water stretch and form a bubble.

The soap molecule looks a lot like a snake - is a long chain has two very different purposes. The head of the snake loves water, and the tail end loves the land. When the soap molecule find a speck of dirt down its tail around the earth and keep it there.

To make the best bubbles school science education at home, you first have to make the best solution bubbles. Gently mix 12 cups of cold water in a shallow pan with a cup Dawn green (or light ivory) soap dish. If it's a hot and dry, add a few tablespoons of glycerin. (Glycerin can be found at the pharmacy.) You can add all sorts of things to find the perfect soap solution: the lemon juice, corn syrup, maple syrup, glycerin ... to name a few. They each add their own properties to the solution of the bubble. (When I teach this class, I have buckets of each variation along shallow dish soap and water so we can compare.)

The most favorable time to make bubbles giant that is on a cloudy day, just after the rains. The bubbles have a thin wall that evaporates quickly in direct sun, especially in a day low humidity. The glycerin adds moisture and discourages the rapid thinning of the cell wall of the bubble.

Council for Science Education Homeschool: Keep a box of Ivory with these items inside: paper clips (in two different sizes), rubber bands, dish soap (clear Dawn and green or blue), straw, rope, plastic berry baskets, plastic water bottles, and wire hangers. The label box "Experiments Bubblology. Pull the tray out, add kids, and one step back.

Zillions of small bubbles can be made with baskets of berries. Simply dip the basket in the bubble solution and turn around. You can also use plastic six-pack soda can holders.

Trumpet The bubbles are created using a modified version of a water bottle. Cut the bottom of the bottle, dip the large end into the soap solution, put the small end to your lips and blow. You can separate the bubble away from the trumpet of the laminate at the large end up and away from your bubble.

Bubble Castles are built with a straw and a plaque. First, the bubble solution is spread across a flat surface (like a clean baking sheet, plate, or table). Immerse the end of a straw into the bubble solution and bubbles the entire surface. Make larger with smaller domes inside. Attention the shape and bubble size changes when connected to another.

Stretch and Squish! Obtain the size bubble in each hand. Slap at the same time (so to join, not pop!). What if I join them slowly?

Light Show is a favorite to teach this class. Find a large flashlight and endure to the end (or use one of three fine clothes pins). Rub the soap solution the rest of the bottom of a colorless plastic lid (like a coffee can). Balance of the cover, her face with soap up in the flashlight (or spring-clamps). Blow a bubble hemisphere at the top of the lid. Find a dark room, light the lantern, and blow gently along the side of the bubble and see the swirling colors.

Weird shapes are the easiest way to show how soap makes the water load. Dip a band rubber completely in the solution of soap and pull up. Stretch the rubber band with your fingers. Twist and adjust in all sorts of ways. Note that the bubble always find a way to fill out the form with the least amount of surface. Making a Moebius bubble by cutting a thick rubber band or ½ "thick tape from one end half back, and replace together.

Polygon forms allow you to square and tetrahedral bubbles. Create different 3D shapes by bending pipe cleaners made into cubes, tetrahedrons, or whatever you want. Alternatively, you can use straw threaded on chain of events in 3D triangular shapes. Note how the film always finds its minimum surface. Can you make square bubbles?

Using Bubbles giant straw and rope, wire two straws on three feet of string and tie. Grasp one straw in each hand and immersion in a solution of soap. Use a wind soft, like walking to make big bubbles. Search heat of air (warm air bags) to make bubbles up, up, up!

Kid-In-A-Bubble in plastic pool of a child, pour the solution of the best of the bubble. Place a hula hoop down, making sure there is enough bubble solution for cover the basket. Have your child stand in the pool (use a bank if you do not want wet feet), and lift the hoop! For a more permanent project, the use of old car tire cut in half lengthwise (the hard way) to hold the bubble solution.
