Easy 6th Grade Science Experiments

Science fairs are a great platform to let children have a hands on experience on various scientific facts. As kids get to perform the experiments on their own, their interest is aroused and they become more involved in the subject.

School kids, especially 6th and 7th graders are often thrilled about performing such procedures on their own. In this story, there are some easy 6th grade science experiments, which are absolutely safe and simple. You can perform them at home for better understanding of the concept.

Science experiments allow you to understand a complicated scientific concept quickly and in a better way. The ones given in this story can be performed using minimal ingredients, some of them coming from your kitchen.

Here, you will use raw eggs, water, and salt for explaining how density of a fluid affects the buoyancy of objects. Take plain water in a tall glass and drop an egg in it. You will find that the egg sinks to the bottom of the glass. Now, take another glass and fill it half with water. Add 4 to 6 spoonfuls of table salt to it and let it dissolve. When all the salt has dissolved, take another glass of plain water and start pouring water in the salt water glass.

Make sure you do not disturb the salty water at the bottom of the glass. Now, take the same egg and drop it in this glass, and see what happens. To your surprise, you will find that the egg keeps on sinking until it reaches half way through the glass, and then starts floating there.

The reason behind this astonishing phenomenon is density. As density of water is lower than egg, egg cannot float upon it. When you add salt, you increase the density of water, so that egg can now easily float upon it.

This concept is same as that of a mini volcano, in which you mix acid and base to create an effervescent gas. You will need an empty bottle, vinegar, baking soda, and a balloon. Fill the bottle with vinegar until it is well below the half mark of the bottle. Take the balloon and start filling it with baking soda by stretching its neck. Fill about 3 to 4 tsp of baking soda in the balloon.

Hold the bottom of the balloon and turn it upside down. Make sure you do not let any baking soda fall into the bottle. Affix the neck of the balloon to the neck of the bottle, without loosening your grip from the bottom. Now gently, release the bottom so that soda starts falling into the vinegar.

As soon as vinegar reacts with baking soda, an effervescent gas shoots upwards through the bottle. As it cannot escape, it enters the balloon and starts inflating it.

Ever wondered why do we love loud music, but simply cannot stand loud noise of the same magnitude? Music soothes our mind and induces a feeling of calmness. Different genres of music have different effects on the human mind. Visit a kindergarten or a day care facility and perform this procedure on small kids.

Play different genres of music and see how kids react, do they become violent and aggressive or do they mellow down and go to sleep? Carefully, note down your observations and make tables and charts showing your interesting conclusions.

This is an interesting procedure, which allows you to monitor the growth of fungus from various samples. Collect a sample on a Q-tip from between your toes, inside your ears, from your dog's mouth, and so on. Place the samples in damp plastic bags and monitor the growth. Which of the samples shows maximum fungus growth? Record your observations.

You can access free 6th grade science experiments and projects on the Internet. Although there is no harm in copying or repeating the project concept, make sure you present them in an innovative way.
