Free Homeschool Science Curriculum - The Microwave Soap Experiment

We see changes all around us. The rusting of an iron object, the ripening of fruit, making of ice cubes, breaking of glass, baking of a cake, the burning of firewood or the souring of milk can teach us a lot about the types of changes that take place around us. I usually include such daily-life examples in homeschool curriculum so that children can learn using everyday occurrences and at the same time know why things change.

When you make ice out of water in a refrigerator, a new substance is not formed. The substance is the same: water. The only difference is that it has changed from liquid state to solid state. This change can be reversed by melting the ice cubes back into water. This type of change is called physical change.
 
When firewood burns, it turns into ash, a new substance. Furthermore, it is impossible to change ash back into wood. Therefore it is a chemical change. These are all occurrences that your child has experienced, and they can bring alive the homeschool curriculum.
 
When a fruit ripens, there is a change in taste and color, indicating that there has been some chemical change. A ripe fruit cannot become raw again, making this an irreversible change. What types of change occurs when glass breaks, when iron rusts or when milk sours?
 
The following experiment can teach us about change and lots more.
 
The Microwave Soap Experiment: You will need an Ivory soap for this experiment. Other soaps will not work as well or may not work at all. Take a microwave-safe dish and place a bar of Ivory soap on it. Place the dish in a microwave oven and run the oven for two to three minutes. Something magical happens!
 
You will notice that beginning from the point where the microwaves converge, the soap begins to foam. The volume of the foam increases within the next minute or so, and becomes about five times the volume of the soap bar. Don't touch the soap till it cools down.
 
Your eyes saw a change. Now touch the soap and find out if it was a physical change or a chemical change. Has the substance changed? Use it with some water and find out if the properties have changed.
 
When the microwaves heat up the air and water contained in the soap, air expands and water turns into vapor. The soap, which is softened by now, expands while trapping air bubbles inside it. As the soft soap expands it forms foam. This is a quick and safe experiment that could add meaning to your homeschool curriculum.
 
Now compare the above experiment to the baking of a cake. When you bake a cake, you mix flour, eggs, essence, sugar and other ingredients into the batter. The end product is something new: a delicious cake. Now, you cannot get the sugar or the eggs or the flour back in their original form. This irreversible reaction is called a chemical reaction.

Thiamine Mononitrate (Vitamin B1)

Vitamins help your body in one way or another. When you want to convert your food into energy, vitamins of the B group effectively do just that. Most food that you eat contains carbohydrates. Without the means of using this food as energy, you will not be able to do anything at all.

The job of Vitamin B is to convert carbohydrates into fuel which is glucose. This undergoes another process which then produces energy. That simple concept is the foundation of your body's metabolism and the functioning of your nervous system. Vitamin B is also important because it also maintains your skin, eyes, hair, and liver.

There are 8 variants of the B vitamins and Thiamine is one of them. It is also known as Thiamine mononitrate. People are more familiar with it being Vitamin B1. This is aptly named because it was the first B vitamin to be discovered.

Thiamine mononitrate is considered to be one of nature's stress relievers. This is evident because it strengthens your immune system and fortifies you body from any stressful conditions that may occur. Moreover, this supplement is very important in the metabolism process. It is an important asset that will form adenosine triphosphate (ATP) which is needed by every cell in the body for energy.

The lack of thiamine mononitrate in the body causes fatigue, depression, irritability and even abdominal discomfort. Since this substance converts carbohydrates, a deficiency of this particular vitamin causes problems in carbohydrate digestion. Other effects of thiamine deficiency cause pyruvic acid, a substance in the bloodstream, to build up. This can result in difficulty of breathing, loss of mental alertness, heart damage, or even beriberi.

In order to prevent this from happening, you should maintain a healthy supply of thiamine mononitrate in your diet. Although most foods contain the vitamin in small amounts, you can find a good supply of thiamine mononitrate in pork and organ meats. Also, rice, legumes, wheat germ, and cereals are some examples of food that contain the vitamin.

You should be able to maintain the levels of thiamine mononitrate in your body so that you can benefit from its positive effects. If you fail to do so, then your body may be at risk for harmful diseases.

Thiamine mononitrate is an important source of energy for your body. If you want to stay healthy, then you should make sure that what you eat contains this necessary vitamin.

Most Powerful Magnets in the World

The strongest magnets available nowadays are the neodymium magnets, made of a combination of neodymium, iron, and boron (abbreviated: NdFeB). They are called rare earth because their composition elements are found in the "Rare Earth" or Lanthanides portion of the Periodic Table of Elements.

First developed in the 1980's, neodymium magnets are characterised by exceptionally strong magnetic properties by even better resistance to demagnetisation, unlike most other types of magnets. NdFeB magnets are extremely powerful by volume and will retain magnet properties for decades (they are considered permanent magnets, even if they are not literally permanent).

This group of magnetic products provides the highest available magnetic energies of any material. NdFeB magnets require extremely high magnetising fields. They are are mechanically week, but magnetically very strong. Two magnets can snap together with enough force to chip or shatter on impact.

Sintered NdFeB magnets are hard and brittle. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is highly recommended for the magnet to be coated.

NdFeB magnets allow small shapes and sizes and have multiple uses in science, engineering and industry. Various kinds of sintered NdFeB magnets in specific shapes and sizes such as blocks, cubes, cylinders, discs, spheres, rods, rings can be ordered.

There currently aren't any known negative health effects from handling NdFeB magnets.

Stegosaurus Dinosaurs

Stegosaurus was a dinosaur that lived during the Jurassic period, between about 155 and 144 million years ago. It was a herbivore (plant eater) that lived in the regions that are today North America and Europe (a Stegosaurus fossil was found in Portugal in 2006).

Stegosaurus is quite simple to recognize. It had a small head, a bulky body, and a tail. Stegosaurus is usually depicted as a quadraped (walking on four legs), but it probably could have stood in a bipedal stance on its powerful hind legs when browsing from the branches of trees. The most recognizable feature of Stegosaurus were the bony plates on its back - these are usually depicted as standing upright, and were arranged in pairs or a zigzag fashion - however there are some scientists who believe the plates may have lain falt on the animal's skin. As well as the bony plates on its back, Stegosaurus also a number of spikes (the number varied depending on the particular species) at the end of its tail.

It is not entirely clear what purpose the bony plates served. One possibility is that they may have helped protect Stegosaurus from predators. Another idea is that because of their large surface area they might have been useful in temperature regulation - helping Stegosaurus to quickly warm itself up or cool itself down, depending on whether they were facing towards or away from the sun.

An average Stegosaurus was about 20 feet (6.1 meters) long, but some animals were considerably larger - the largest animals grew to a length of 30 feet (9.1 meters) and weighed around 2 tons.

The Top 5 Strangest &quot;Benefits&quot; Of Creatine

1. Does not increase muscle mass

So this is a hidden benefit because this proves that creatine is not a drug. What really happens in the real world to your body when you take creatine... the energy source your body uses for fast muscle movements like weight training is called ATP-CP. What happens is you body breaks down ATP and the breaking of those bonds releases energy for you to use.

Creatine naturally occurs in the body, but when you put more into your system, you are allowing your body to take ADP, the resulting amino acid from the break down of ATP, and turn it back into ATP. This simply gives your muscles more energy.

Muscle mass increase not from creatine, but because of the extra energy that creatine is allowing your body to produce. This lets you complete more reps and sometimes heavier weights.

2. Creatine gives you brainpower

Say what? More energy to grow your muscles and now increased brainpower? This creatine is beginning to seem like a miracle supplement.

Researchers at the University of Sydney and Macquarie University ran a study that found increased brain capacity. The test included an IQ test and things like remembering numbers chains. They used vegetarians because creatine is produced in the muscles of animals as well, they didn't want those dosages of creatine to affect their results.

However, they found that in the short-term the people that received creatine were able to perform better at each test. Dr. Rae, a doctor at the University of Sydney, was quoted as saying... "creatine supplementation give a significant measurable boost to brain power." Pretty cool huh?

Dr. Rae drew the conclusion that creatine was able to provide the brain with more energy to use for computational tasks. Make sense because creatine is all about creating more energy for your muscles!

3. Creatine can combat cancer

Now this is sounding a little too good to be true. However tests have been run and there is a connective tissue disorder called Dermatomyositis. This is a connective tissue disease that is marked by inflammation of the muscle and the skin. Up to 50% of the cases of Dermatomyositis actual contain the presence of cancer.

The muscles with this condition get so weak that you will actually have trouble moving, getting out of chairs, raising your arms, and even trouble holding your head up. You neck muscles can actually be that weak. So you can see this is a serious condition. Good news is that is very rare.

Creatine was introduced in two different studies, one in the UK and one in Sweden. The studies only worked with around 37 people, so as with all studies... further studies are required. However, creatine plus exercise according to this study showed a muscle strength increase in the subject that received the creatine.

4. Creatine fights the progression of Parkinson's Disease

Chalk another incredible benefit for creatine!

Studies have shown that creatine has severely slowed the progressive nature of Parkinson's Disease. Dr. Dian Murphey at the Nation Institutes of Health, commissioned a study of 200 patients in the early stages of Parkinson's.

These particular patients have not received any prior medication for the condition. So in these early diagnoses of PD (Parkinson's Disease), the speed at which the brain degenerates was slowed down.

Similar studies have found when creatine was tested on mice, I know not the best comparison, but... when tested on mice, the creatine acted as an antioxidant that prevented damage from compounds that are harmful to brain cells. Also the mice experienced no loss of the cells that are typically affected by PD.

5. Overall health in middle to older age men and women gets better

I am beginning to wonder how creatine ever got a bad name to begin with. This last "strange" benefit deals more with the normal affects of how creatine is typically used.

As the human body grows older the natural aging process will naturally deteriorate the muscle mass in your body and increase the amount of body fat. Unless you do something about it, you are looking for a painful number of the golden years.

To help middle to older aged men and women, a study was done to find out the affects of using creatine to help with their resistance training and muscle building. Surprising enough the men and women saw greater muscle benefits from taking the creatine.

They had increased endurance and muscular strength. This alone reverses the natural progression of the body and these subjects say body fat go down the muscle mass go up!
