big bubble ball Bubblology Experiments

(Including bubble Castle, light show and a child)in-a-bubble).It's also good for Scout or any kid who loves science experiments who work on badges.These experiments are part of the family School Science program I teach and I promise your child will like it.
If you pour a few drops of water on a sweater or fabric, you will notice that the water will take the ball (or oval shape, if the drop is large enough ).If you touch the water ball with a soap finger, the water ball will disappear into the fiber of the fabric!What happened?Soap "moistens" the water by reducing the surface tension of the water by about twice"thirds.The force that keeps the water droplets spherical is called surface tension.
That's why you can fill a glass of water without spilling it.The water becomes "wet" because without soap it can't get into the fibers of your clothes and make them clean.That's why you need soap in the washing machine.
Soap also makes the water elastic.
If you ever try to spit bubbles in your mouth, you know you can't get a bigger fistsized spit-Bubbles are formed completely and separated floating in the air.The water itself has too much surface tension and too much force to gather the molecules together.Soap, they relax and stretch.Soap stretches the water and creates bubbles.
The soap molecule looks like a snake-it's a long chain with two very different ends.The head of the snake loves water, and the tail loves soil.When the soap molecule finds dirt particles, it wraps its tail around the dirt and holds it there.
In order to create the best foam for science teaching in home schools, you first need to create the best foam solution.Gently mix 12 cups of cold water in a shallow tub with a glass of green Dawn (or transparent ivory) dish soap.A few tablespoons of glycerin.(You can find glycerin in the pharmacy.Find all kinds of things that are perfect for a solution of soap: lemon juice, corn syrup, maple syrup, glycerin .
..... Wait.
Each will add its own properties to the bubble solution.(When I was teaching this class, I had all sorts of buckets and regular soap and water so we could compare.) The absolute best time to make huge bubbles is on a cloudy day, right after the rain.
Bubbles have a thin cell wall and quickly evaporate in direct sunlight, especially at low temperatureshumidity day.Glycerin increases moisture and prevents rapid thinning of bubble cell walls.Tips for teaching home school science: it's convenient to put a box in it: paper clips (two different sizes), rubber bands, soap (clear Ivory and green or blue dawn ), straw, rope, plastic pulp basket, plastic water bottle and wire container.
Label your box with "bubble learning experiment.Pull out the box, add the child, and step back.Numerous small bubbles can be created with a strawberry basket.
Just dip the basket into the foam solution and rotate.You can also use plastic sixGas tank rack.Trumpet bubbles are produced by using a modified water bottle.
Cut off the bottom of the bottle, dip the large end into the soap solution, and blow the small end on the lips.You can separate the bubbles from the trumpet by rolling the outsole up and away from your bubbles.The foam Castle was built with straw and plates.
First, apply a bubble solution on a smooth surface (such as a clean cookie sheet, plate, or table top.Dip one end of the straw into the bubble solution and blow the bubble across the surface.Make a larger dome with a smaller dome.Note that when the bubble is connected to another bubble, it changes the shape and size.
Stretch and squish!Get one hand-There are bubbles of size in each hand.Put them together (so they join instead of pop music!).What if you put them together?When I teach this class, the light show is one of my favorite shows.
Find a big flashlight and put it at the end (or use a thin flashlight with three clothes ).Rub the soap solution at the bottom of the uncolored plastic cover (like rubbing from a coffee can ).Balance the lid on the flashlight (or spring) with soap side upType hat ).
Blow a hemisphere bubble on the lid.
Find a dark room, turn on the flashlight, blow it gently along the side of the bubble and watch the color spin.Strange shapes are the easiest way to show how soap makes water elastic.Dip the rubber band completely into the soap solution and pull it up.
Stretch the rubber band with your fingers.Distortion and adjustment of various shapes.Note that bubbles always find a way to fill the shape with a minimum surface area.
Create Mobius bubbles by cutting a thick rubber band or a "thick ribbon" to give one end and a halfScrew and reconnect together.Polygon shapes allow you to make bubbles of square and four-sided triangles.Create a different 3D shape by making the pipe cleaner into cubes, tedrahedrons, or whatever you want.
Alternatively, you can use a straw attached to a rope in the shape of a 3D triangle using a thread.Note how the film always finds its minimum surface area.Can you make square bubbles?Use the huge bubble of the straw and the rope, twist two straws on the 3 feet rope and tie the tie.
Grab a straw with each hand and immerse in a soap solution.When you walk, make big bubbles with soft wind.Find the air heater (warm air pocket) and bring your bubbles up!Kid-In-A-Bubble in the children's plastic pool and pour in your best bubble solution.
Drop the hula hoop and make sure there is enough bubble solution to cover the hula hoop.Let your child stand in the pool (use a stool if you don't want to get your feet wet) and lift the iron ring!For a more permanent project, use the longitudinal semi-sliced old car tire (hard way) to hold the bubble solution.As a teacher, science teacher at home school, engineer and university lecturer, Aurora Lipp has helped children learn science for more than ten years.
