Science Fair Project Ideas

Unlike a lot of other subjects, science is purely based on facts and truths. It involves explaining and predicting various phenomena using experiments. Compared to adults, kids have a higher tendency to absorb things that they see and hear around them. As such, this is the best time to teach them science subjects. Traditionally, science subjects would be taught using textbooks. However, it has been scientifically proven than cognitive learning techniques are better than the traditional methods. Cognitive learning involves touching, watching, listening and experiencing. This is one of the main reasons why science activities for kids are gaining steady popularity.

There are various projects and experiments that can be used to teach science subjects to kids. In addition to keeping them interested, such activities will give them a better grasp of the subject. Science education is a vast field comprising of various subjects such as social, space, earth, life, physical, etc. Learning such subjects provides the kids with certain skills that are required to lead a fulfilling life. Scientific literacy is an integral aspect of today’s society. It enables one to think and take responsible decisions. Increasing population, diminishing natural resources, global warming, poverty, drug resistant diseases and political turmoil are just a few of the numerous problems faced by the world today.

Proper scientific education prepares the kids to face such problems and tackle them effectively. Including science projects in the curriculum is a good way to ensure that they receive proper scientific education. While choosing such projects, parents and teachers must ensure that the activities are entertaining as well as informative. Monotonous projects rarely serve the intended purpose. The internet is filled with numerous science experiments that parents and kids can try out at home. Furthermore, there are several online videos that can be used to teach the kids. It is a well-known fact that interactive videos can capture the attention of kids.

Certain science projects involve more than one person. Educators can try such projects at school. They can divide kids into groups and assign a project to each group. Regardless of the activity, teachers and parents must keep an eye on the kids. Certain activities, especially those involving potentially dangerous substances, should be demonstrated to the kids rather than letting them do it by themselves. There is no denying the fact that science experiments for kids have a significant influence on their scientific education. However, care should be exercised while selecting the experiments so that they are more informative than entertaining.

There are a number of different kinds of solar power systems customers can choose from. Deciding which ones you want will depend to great extent on what you find important. The main difference between the different kinds of systems has to do with which kinds of panels they use. In general, the most efficient solar panels are the most expensive. This is a bit of a trade off. You can save money up front by installing less expensive panels, but you save more money in the long run by installing more efficient ones. In the following paragraphs, you will learn about three of the most popular types of panels, beginning with the most efficient.

Single Silicon Panel Based Systems

It is important to define what is meant when it is said that that single silicon panels are the most important solar panels available. In a nutshell, more sunlight is converted to electricity by these panels than by any other kind. This is because of their higher silicon content. Of course, that higher silicon content also makes them more expensive. On the other hand, because they are more efficient, you need fewer of them. The fact that fewer of these panels can produce the same amount of electricity as a larger number of less expensive ones make them especially suitable for rooftop installations.

Polycrystalline Silicon Panels

Also known as “poly” panels, these panels are typically used in some of the least expensive solar power systems customers can buy. They are commonly used in roof installations as well, because they only take up slightly more room than single silicon panels. Even though they are less efficient, they are not the least efficient option. Therefore, they make an excellent choice for customers looking to strike a balance between initial affordability and long-term efficiency. As you can probably imagine, these facts make them extremely popular choices for residential solar systems.

Building Integrated Panels

These are also known as “building integrated photovoltaic’s (BIPV’s). They look like part of your roofing, and because of that, they are commonly referred to as “solar shingles.” This is a great idea for people whose main objection to the installation of solar panels is their appearance. The only problem is that BIPV’s are the least efficient solar panels commercially available. As a result, you need a very large roof with lots of sun exposure if you want to be able to use these panels to produce enough electricity to lower your energy bills. Another drawback to solar shingles is that they do not last as long as your other options would.

Now that you are more familiar with the different types of solar power systems to choose, it should be easier for you to make your own decision. Obviously, you will need to find a company that offers the kinds of panels you are interested in. In any case, a proper installation will make a significant dent in your energy expenses in the long-term, and solar power is environmentally responsible as well.

It’s a warm day, and you would like to take your kids out on a picnic. How about converting a homeschool science experiment into an ice cream making session? Amaze your kids by showing them that with their help, you can make ice cream for them, and that too at their favorite picnic spot.

You will need to do some preparations the previous night or an hour before you set off for the picnic. Boil a mixture of one cup of milk with half a cup of sugar and a pinch of salt in a boiling water bath. Add three beaten egg yolks to the mixture and stir till you get a thick custard-like mixture that coats the spoon. Cool it and add vanilla essence and about two cups of heavy whipping cream and stir. Pour the mixture in 3 to 4 small zip-lock bags, each enough to make one serving. It is preferable to secure this bag with another zip-lock bag. Now put the zip-lock bags with the mixture in an ice chest full of ice. You can now put the ice chest in your car as you travel to your favorite picnic spot. It is very essential that the ice does not melt on the way for your home school science experiment to be a success.

At the picnic table you can put each zip-lock bag into a larger zip-lock bag that is half filled with ice. Sprinkle some salt over the ice and seal the large bag. Do this with all the smaller bags containing the ice cream mixture. Adding a little water to the ice will help enhance the process. Have as many such bags as many kids there are. Hand over one such bag to each kid and ask the kids to squish and shake the bags. Maybe they can toss them up and catch them. The more they squish and shake the bags the faster will the mixture turn into ice cream. Let them have fun with the bags for ten minutes. You can allow another five minutes of shaking, shaking and shaking!

Then ask each kid to bring their ice cream pack to you for examining. Open each bag, and voila! Ice cream’s ready! Once done, let them enjoy their frozen treat! Isn’t this a fun home school science activity? How did the liquid mixture turn into ice cream? And that too, quicker than it would take in a refrigerator? The very first thing to remember is that you have divided the mixture into smaller bags and not into one container as you would do in a refrigerator. Without salt, when ice melts (at 0 degree Celsius or 32 degrees Fahrenheit), it turns into water by absorbing some heat from the atmosphere. At the same time the water gives out heat and refreezes into ice. This is called a state of equilibrium. The mixture requires a temperature less than 0 degree Celsius in order to make ice cream.

Salt breaks this equilibrium by changing the make-up of the ice and the water. Now the ice melts, but the water does not refreeze into ice since it now requires a temperature less than 0 degrees Celsius to refreeze. The ice now gets no heat to melt, and therefore draws heat from the mixture, making the ice cream mixture even colder.

Furthermore, salt (sodium chloride) splits up in the water into charged particles of sodium and chlorine. The whole mixture of ice, water and salt now becomes a special compound that freezes at a temperature of -21.1 degrees Celsius or -6 degrees Fahrenheit. Therefore the liquid ice cream mixture becomes a frozen paste. To get more great science experiments and activities visit the free “Home school Parent’s Guide to Teaching Science” at the link below.
