So do not let us think that science is complete and will not be found new things again. Moreover, not let us think of what for teach our younger generation experiments science project. Because we think the science is complete so we think our young generation just has to memorize it. Not! This idea is not right at all. Our kids should be taught about the science project experiment as early as possible. Many benefits can be obtained our kids out of the habit of applying science project in solving everyday problems. Among the mindset of the child to be developing, when faced with the problem our kids not quickly collapsed and despair, the kids is no longer focused on the sadness of the problems that faced but more focused on finding a way out of the problem, that some of the reasons why the kids need to be introduced to the science project. But if you still do not have a picture, here we explain the example of kids’ science projects experiments:
Make oil and water to be mix
Things must be prepared:
- Bottles of mineral water
- Water
- Oil
- Food coloring
- Detergent
What to do:
Pour water which has been mixed with food coloring into bottles of mineral water. But do not get too full just fill half of it. The purpose of coloring the water is only so that the water apparent. Pour the oil into the bottle and shake. Allow the bottles and see what happens? Water and oil do not want to be mixed. Water is at the bottom layer and the oil is on the top layer. If you try to repeat the steps shaking the bottle as hard and as long as possible despite the oil and water still does not want to be mixed. How to make oil and water are mixed?. Now pour a little detergent and shake the bottle again. Look and see the results. After plus detergent, it is now willing to mix water and oil. How does science explain this?
Both water and oil have stronger bond cohesion of the adhesion. Cohesion is the force of attraction between particles of similar while the adhesion is attractive forces between the particles of different types, in other words the attraction of water particles with water and oil with oil particles stronger than the tensile force of water with oil. That is why water and oil seen do not want to be mixed. Water and oil can blend with added detergent. Detergent molecules consist of the head and tail that is bipolar. One part binds to water and other parts bonded with oil. This is why when you are washing dishes or clothes using soap, so that the fat can be dissolved and clean when rinsing by water.
Thus example of kids’ science projects experiments. Have a nice project experiment. >
