Some people can remember things almost effortlessly, while others struggle to keep in mind the most basic things. In this science experiment we are going test the memory of your friends and family. The optimum number of people to test is between 5 to 10. So make a list of all the people whom you can get to participate.

Next make a random sequence of all number from 0 to 9. Note it down. Then repeat this step till you have 10 random number sequences with you. Write down or print out each number sequence to an index card. On the back of the first index card write 1, the second write 2 and so on.   You will now have 10 index cards with a random string of numbers on them.

These will be used to test your volunteer’s memory. Give the friend the first card to read and memorize. Repeat with all ten cards. Now read back a string of numbers from a particular card and ask him which number index card it was written on. Go through all the index cards in random order and mark the right or wrong answers given by your friend.

After you have the answers of your friend you can calculate the percentage of how often he was right. The higher the percentage the better his memory. Repeat this science experiment with all your other volunteers. You can change the test by asking them to recite the number string on a particular index card to make it tougher.

One of the most difficult fields of scientific research is social behavior. Every year a large number of scientific studies are undertaken to try and understand the human nature better. Some of them come up with conflicting results, other defy common sense and logic, but all of them are immensely entertaining.

Most of the studies are based on the volatile area of relationships, while courtship rituals and dating behavior tend to dominate the scene. So it isn’t surprising that at the University of South Brittany a study was conducted to see how the weather could affect social behavior.

In specific, an attractive 20 year old male approached women in the 18-25 age bracket walking alone down the road and asked for their phone number. The solitication took place on cloudy days and sunny days but not on rainy days. The data collected indicated that the women were more receptive and open to flirtations when it was sunny as compared to when it was cloudy.

So if you are looking to get the phone number of that special girl, just wait till its sunny. Why not give yourself the boost of knowledge from a scientific research project to up your chances of getting that phone number?!

You think of a lake and its  usually pictures of still open waters on which you can float a boat that come to your mind. Not so with the lakes buried under Antartica. These lakes are hidden below many layers of ice, but they do exist as the US scientists who drilled into Lake Whilliam recently proved.

This lake which is buried almost under a kilometer of Antarctic ice was sensed by the drilling equipement. The breakthrough was then verified by sending down a remotely controlled camera. The scientific exploration project at Lake Whilliam is not th eonly one of its kind.

There have been ongoing efforts to shed light on the buried lakes of Antartica by a number of different nations. Last December a team of British investigators were unfortunate and had to leave their study of Lake Ellsworth incomplete as they faced technical problems.

The Russians were sucessful in obtaining samples from Lake Vostok, another buried lake in Antartica. They have not yet announced any major discoveries based on the tests conducted on the water sample as yet. There are more than 300 identified bodies of water under the Antartic ice and the scientific exploration project will be a long one.

Now that we know how to spot germs on our hands we can convert it into a full fledged science experiment. The objective is going to be to find out which part of the hand the germs cling to the longest and how the lenght of time spent washing hands affects them.

Besides the Glo Germ Gel and the Ultra Violet Light pen you are going to need a few friends to help you carry out this experiment. First record the area of germ concentration on the individual’s hands before washing hands with soap. Then record the reduced germ concentration areas. Then make them wash their hands for another two minutes thoroughly and see how many germs are left.

You will need to repeat the process with each friend who takes part in the experiment to collect enough data to examine. Now corelate the data to find which parts of the hand are the most difficult to rid of germs. You can divide the hand into sections like palms, fingers, between the fingers, around the fingernails and the back of the hand.

Note down all your observations and formulate the conclusion based on these observations. You can make two lists for after the first hand washing and the second hand washing. It is an easy and interesting science project to do.

There are germs everywhere, or so we have been told. In this fun to do science experiment we are out to prove that there are indeed germs to be found in abundance all around us. Germs are essentially microscopic organisms which are so tiny that they cant be seen by the naked eye.

Not all germs are bad for us, but some kinds of bacteria and viruses can make us ill. So it is a good idea to get rid of any germs on your hand before every meal. After all who knows which germs on your hand are going to cause you to fall sick and which ones are harmless.

 Thanks to Glo Germ Gel we can now actually observe the germs on our hands using the ultra violet light pen. First apply the gel to your hands like you would use a hand lotion. Now darken the room and shine the ultra violet light pen on your hands to see where germs are concentrated on your hands.

Now go to the sink and wash your hands with soap and water nicely. Return to the dark room and shine the ulta violet light again. You will see that washing your hands has truly helped you get rid of a number of germs on them. Try out this science experiment with your friends for fun.

There are a number of ways that a seed can move away from its parent plant and put down roots to reproduce. One of the most common means of seed dispersal is blowing in the wind. Here in this science project we will investigate how the size and shape of a particular seed can help or hinder in wind dispersal.

Take a look at the different kinds of seeds you will need. Make sure there is enough variety such as a coconut, a dandellion seed, burdock seed, apple seed and mango seed will do fine. Each seed is of a different size and has specific characteristics. Now we need to decide which one is ideal for wind dispersion based on their size, mass and shape.

A coconut is obviously much too heavy for wind dispersion due to its heavy mass. A mango seed is also heavy and these two may be better suited for water or animal dispersal. With seeds of apple, burdock and dandellion which are all relatively light consider the texture of the seeds.

 The hook like burdock seeds are better suited to clinging to animal fur and being dispersed and the smooth apple seeds are more likely to be swallowed by the animals. Blow all the seeds away and you will realize that the fluffy dandellion seeds are more suitable to parachute down greater distances from the parent plant in the wind. make detailed observations to support your science projects.

A little seed is a very important part of our lives. The potential plant lying dormant within the seed can produce food that will feed us enabling us to live. This biology based science experiment is simple and easy to follow. Just take a look at the various ways nature has provided plants to protect their seeds.

In this experiment here we are going to take a look at the different kinds of seeds that fruit plants produce. If we try and make a comprehensive study of all kinds of plant seeds the scope of the experiment will be way beyond your grade level. So pick between five to ten fruits that are commonly available to get started.

A few good ones are Apples, Peaches, Coconuts, Mangoes, Grapes, Oranges, Kiwis, etc. The things that are going to be observed and recorded in the project include the size of the fruit as compared to the size of the seed, the number of seeds per fruit and the protection provided by the fruit.

You can pick other factors if you want to make a more detailed science project out of it. You will need to physically examine each fruit and its seeds to record your observations. Make sure you take plenty of pictures to make it visually appealing.

<p>It seems that your daily sweetened drink may have you at a higher risk for depression as per a recent scientific study. Dr Honglei Chen is the author of a new study conducted at the National Institutes of Health in Research Triangle Park in North Carolina. The study claims that adults who have sweetened beverages on a regular basis can be at an increased risk of triggering depression.<br />
As per Dr Chen sweetened beverages like coffee and tea may have important mental health consequences. The study was conducted on 263,925 people who were in the 50 to 71 age group. They were evaluated on their consumption of sweetened beverages like soda, fruit punch, tea and coffee over a period of ten years.<br />
At the end of the decade the participants of the study were asked if they had been diagnosed with depression. As per the records 11,311 participants out of the original 263,925 had been diagnosed with depression since the year 2000. While others might argue that such a portion of the participants being diagnosed with depression may have little to do with their beverage intake habits, the tentative link has been established.<br />
Sweetened beverages have had a full blown effect on obesity and weight gain in other scientific studies and this may be another ill effect that you may have to watch out for. The initial study does need to be followed up further before conclusive results can be announced. It may be healthier to take your beverages minus the sugar for the body and the mind in the future. </p>

A simple chemical reaction can be used to blow up a balloon as demonstrated in the last blog post. Now learn how you can use that simple scientific demonstration to make a full fledged science project. The process of the experiment has already been described so here we will focus on the variables that you can use to create the science project.

The size of the water bottle can be the first variable that we use in the project. Does the smaller half liter bottle help blow up the balloon better than a larger one liter bottle? Follow the identical process in both cases and note the difference down in your notebook.

Another variable can be the temperature of the vinegar in the water bottle. Warm up the cup of vinegar in the microwave for a minute and cool down another cup of vinegar in the freezer for one minute. Now use the two different temperatures of the cups of vinegar to observe what happens in the science experiment.

The last variable that you can use is the amount of baking soda that you fill into the balloon. Does two spoons of baking soda fill it up faster than one spoon. What happens if you increase the quantity to three spoons. Answers to all these variables will give you a great science project.

Here is another balloon based science experiment that you can perform. We use the by product of a simple chemical reaction to inflate a balloon. Here’s what all you will need to conduct this experiment.

A half liter water bottle, a balloon, a cup of white vinegar, couple of spoons of baking soda and a funnel. In case you don’t have a funnel handy you can make one out of plain paper by making a cone and taping it to hold it in position.

Stretch the balloon out a bit by pulling it along to loosen the rubber in it. That way it will be easier  Now use the funnel or paper cone to fill the baking soda into the balloon and keep it aside. Pour the cup of vinegar into the empty water bottle.Very carefully without letting any of the baking soda fall into the bottle attach the mouth of the balloon onto the open mouth of the water bottle that contains the vinegar.

Make sure that its a good fit and no air can escape out of the sides. Now hold up the balloon straight so that the baking soda inside can fall into the bottle. As the baking soda reacts with the vinegar the reaction will cause the release of a large amount of carbon dioxide which will shoot up into the balloon and inflate it. A simple science experiment that you can amaze your friends with.
