Electricity is an interesting subject. There is so much you can learn from it, like how our lights turn on or how we make cell phones. This is all a mystery until we finally get a little bit of information in our brains. I've just read two articles, "Energy Story" and "Conducting solutions". I also watched a video called Hands-on Science with Squishy circuits. I learned so much valuable information from these resources.
In the article,"Energy Story", it tells you all about basic energy and how scientists found out how it works. It tells you about each part of an electron and what part is what. The center is called the Nucleus. Electrons and atoms move together to create what is known as electricity. Atoms and electrons flow through an object

When a solution conducts electricity, the charge is carried by ions moving through a solution. Ions are atoms or small groups of atoms that have an electrical charge. Some ions have a negative charge and some have a positive charge. Pure water contains very few ions, so it does not conduct electricity very well. Not all substances are made up of ions. Some are made of uncharged particles called molecules. Sugar is such a substance. When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. That's why in Hands-on Squishy Circuits, the sugar PLAY-DOH did not produce electricity. The salt had ions in it to produce the electricity needed to make the LEDs light up. In Hands-on Squishy Circuits, AnnMarie Thomas showed us how she took a home-made PLAY-DOH recipe and turned it into a science experiment. It’s amazing that three and four year old children play with something so revolutionary. We may not realize this now, but if we start introducing this stuff to these children, they’re going to become such intelligent adults. I ask myself this question everyday,”Do I want my child to be successful in life, or let them flip burgers at McDonalds?”. I want my child to be able to learn and succeed as they progress in life. This is extremely important for children these
In "Energy Story" uses an explanation of atoms and tells us the parts of an atom and its structure. In the text it
Concrete operations (ages 7-11) – As a child accumulates experience with the physical world, he/she begins to conceptualize to explain those experiences. Abstract thought is also emerging.
Electrolytes are substances that have the capacity to conduct electricity when it is dissolved in water. In an “electrolytic solution”, if two electrodes, one being positive and the other negative, are placed in the solution then ions have the ability to transport free electrons to and from both of the electrodes. Electrolytes have the ability to created currents, however a stronger electrolytes will be able to conduct more current than a weaker electrolytes. Acids in a solution are good electrolytes since the acids supply the solution with hydrogen ions. If a solution contains organic compound has sugar or starch, then that solution won’t conduct electricity well since organic compounds are contributing as many hydrogen ions as acids. Electrolytes can be found in modern technology and allow them to function for example power watches, cars, and flashlight rely on electrolytes to be able to function. In these
The flow of electrons makes a charge that delivers useful power which could be used to light an LED
Sensory play is a wonderful medium for children. Through hands on investigations Eva is able to build her own theories about her world and explore new ideas. It is also a great way to introduce early math and science skills. During the experience we use descriptive language and propose questions that promote the development of these skills “is it full? is it empty? Is it heavy? how can we? why do you think that?”
The three stories that I have read about electricity has a purpose or a main idea. In "Energy Story" it was about showing the importance of electricity and how much an average human has that is bound to work with electricity. In "Hands-on Science" they taught you how to make your own circuit or electricity by normal thing in your kitchen. Finally, in "Conducting Solutions" they think of random stuff to conduct solutions for electricity. All three of these stories had something in common, these where all ways to show the importance of electricity and how to save it.
way to take banal scientific concepts and explain them to kids in such a cool and captivating way
The four concepts present in our toy is object permanence, palmer grasp, sensory stimulation and self-recognition. Object permanence is the ability for the child to understand that an object continues to exist even when they cannot visually see it (Martin and Berke 176). Garden Adventures promotes the development of object permanence by playing with the Peekaboo Bunny. Parents promote play by hiding the bunny in the bush and eventually the child will understand that bunny is still present even though they can not see it. Similarly, Garden Adventures promotes sensory stimulation through the different textures, sounds and smells present. Sensory stimulation information processed through taste, touch, visual, smell or audio (Martin and Berke
To understand how this electricity works we must start with the basics. The atom is the smallest unit of matter, consisting of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Electric charges that are the same repel each other and charges that are different attract each other. Electric charges can exist alone, unlike magnetic poles.
For a second, imagine yourself in a frozen cabin, with wet wood, oil and wax, trying for hours to make a fire in order to get light and heat in your room. This procedure ended in 1897, thanks to the American inventor Thomas Edison, who was finally able to produce a long-lasting light-bulb in his laboratory. Although it looks simple that turning on the lights just require to turn the switch on, the scientific theory behind it is quite complicated. Creating an electrical system requires a conversion from any sort of energy to electrical energy. For example, one of the first electrical energy sources was coal. Burning coal produces high temperatures that transfer into potential energy. Potential energy is then changed to electrical by the application of stress.
Children love toys. That is not new news. Some toys are for mere pleasure while others have learning content. Classic toys known as shape sorting toys offer not only entertainment for young minds but also help contribute to a child’s physical, emotional, social, and cognitive development. Shape sorters are a favorite among young children and infants. This is because they are challenging to the child, yet still fun. By figuring out how to drop each piece into its proper hole, kids learn to categorize and eventually name shapes (a skill they master around age two). Between fifteen and eighteen months, most kids will start to develop the hand-eye coordination and problem-solving skills they need to be able to sort. Shape sorting toys are great aide to the development of a young child and many developmental theories can be applied to support the fact. (“Benefits Of Shape Sorter Toys”)
The ability for children to discover is innate. From birth children discover all sorts of different things about the world around them. It has even been said that "babies are as good at discovery as the smartest adult" (Gopnik, 2005). Discovering is the natural way that children learn. By interacting with the world around them, they ar...
We have come a long way from where we are now and when we started. During the beginning of time, we did not have cars, stoves, or even cellphones. Now thanks to several different inventions and discoveries we hold the opportunity to use many things that can help us with our daily tasks. Electricity is one of the major inventions that helps with operating all the electrical base appliances we use on a daily basis. Almost half of the electricity used by industry is for lighting. Most of the light is produced by incandescent light bulbs. What is an incandescent light bulb? How does it work? Who was it discovered by?
Crystals with ionic properties, such as sodium chloride completely dissociates in water. Thus, ionic compound form crystal, they have a high melting point and known to dissolve evenly in aqueous solutions. Water molecules have conduction properties, which makes the dissociation process conducive. Consequently, this physical states will contribute to the ionic compounds to conduct electricity. ( Ian Guch and Cavalcade Publishing, 1998-2009)
Also on the horizon are smart objects. These objects are geared more to small children then those in high school or college. Objects with animations such as building blocks that can talk and light up to indicate to a child how to stack them correctly. Objects that will test a child’s spelling and reading skills. Smart books and tools that require a child to listen and react.
