Bubbles Away

There is nothing as much fun as blowing bubbles. Big ones, small ones, a great many altogether. Its all a matter of how you twist the hand and blow the air.  And guess what this fun activity can also be turned into a science experiment project. All you need to do is take some notes while you are having fun.

Here’s how we will convert bubble blowing into a science project worthy of entry in a science fair. First we need a problem to serve as the hypothesis. So lets say we are looking for the bubble solution that makes the bubbles last the longest. Or you could be looking for the bubble solution that makes the largest sized bubbles.

Next you need to mix up three to four different types of bubble solutions. Vary the basic ingredients of the bubble solution in ratio to see which bubble solution makes the best bubbles as per your hypothesis. Make sure that you record all the bubble blowing attempts and measurements.

This data can be represented in a nice table highlighting which particular combination worked the best for your bubbles. At the science fair have two of the bubble solutions available for blowing bubbles as part of your display. Have the best and the worst bubble solutions as per your data on hand to illustrate the difference with ease. Can you think of a more interesting science fair project?

Making fog in a bottle

Have you ever driven into the majestic mountains. What happens as you go higher up in altitude? The misty light fog that floats over the mountains is an enchanting sight indeed. You wish you could hold it in your hands and know that it will never happen. Or will it? Now imagine being able to make that fog in a bottle. Its a simple project that even a five year old can do. Check out just how to do it below.

Get a long neck bottle such as an empty glass soda bottle. Now just fill the bottle almost half full with hot water.  You can get an adult to help you heat the water up on the hob. Once you pour in the hot water let it sit a few minutes, then empty most of the water out. Just leave about one inch of hot water in the bottom of the bottle.

Now get yourself an ice cube out of the freezer. And stick in the ice cube in the neck of the bottle. Remember that the cube should block the neck of the bottle. Before your very eyes the fog will begin to form between the water and the ice cube. Here you go, fog in your hands. Try another interesting science project.

Small Science Projects to do at home

There is nothing like a few science projects to make the summer holidays fun.Of course some of these activities are best done under adult supervision so make sure you have someone around.

Make your own Cloud – here’s how you can catch a cloud in a bottle. Pour some water into a two litre plastic bottle. Now light a match and drop it in to the bottle. You can get a grown up to help you do this. Now cover the lid of the bottle immediately. Squeeze the bottle for a while and you will see your cloud beginning to form inside the bottle.

Color your own Flowers – you are going to need a number of white colored flowers. Take your pick from carnations, gladioli, roses,or any other white flower of your choice. Now cut the stem of the flower diagonally. Place it aside. In a flower vase add some water and a spoon full of food color. Now stand the flower stem in the vase and leave it overnight.  The next morning you will find that the flower is no longer white. It would have taken on the tinge of whatever food color you used.

There are a number of other experiments that you can do. Stay posted for the next blog post with even more interesting science projects to do at home.

Hands on Science Experiments

There are any number of science experiments that you can do at home. It has been proved time and again that a hands on approach to science results in better learning and retention. So if you read about a principle or theory you will remember it with some effort. But the minute you do a practical experiment based on the theory you will remember it with no effort at all.

That’s why hands on science experiments are a must. So what are a few such experiments that you can take on? There are many simple projects that need no elaborate set up, materials or extra learning.Further more each room in the house can give you a science experiment.

You can build yourself a baking soda volcano in the kitchen. Or do an experiment on buoyancy in the bathroom. You can use light waves from a lamp in the sitting room to prove that light travels in a straight line. As you can see the possibilities are many and endless.

All that is required is a seeking spirit and a curious mind. If you look at everything and wonder how it works you care well on your way to a hands on encounter with science experiments.

What do Science Projects teach you?

All of us have done some science projects at one time or the other. They are an inescapable part of modern education. However these formal science projects teach us more than the basic principle that they are based on. They teach us different transferable skills that stay with is long after these projects have been forgotten.

So what are these skills? The first would be the ability to make a prediction. One that is based on facts and consideration, not on a guess. This prediction is what serves as the basis for the hypothesis of the science project.

The next skill is knowing that if one variable changes the whole project can change. This cause and effect relationship is what helps us understand that if you change one thing the whole situation changes.

Then there is the skill comprehension. We read so many books, magazines, and articles to do the research for our project. We understand what is essential and leave the superfluous out. Then we get down to actually doing the science project.

Of course we also enhance our language skills and arithmetic skills if the project involves manipulating numerical data. Naturally these are skills that we put to use long after the science project is over.
