Easy Science Fair Projects to Do With Kids - How Ships Float [sciencetechnology-center.blogspot.com]
Most parents and especially homeschoolers are always on the lookout for easy science fair projects to do with the kids. Here is one of our very easy science fair projects to do with the kids. In this project you are going to learn how ships float.
Simple boats such as rafts float because they are made of material that is lighter than the water. Usually materials such as light wood or reeds, that are less dense than water, are used.
Heavy boats work differently and they float as a result of the upthrust of the water that occurs because of their weight pushing on the water. The upthrust is their pushing force. By putting something on the water and letting it go, you will see that it is pushing the liquid out of the way. The further it goes the more water it pushes up. Now, when this upthrust becomes the same as the object's weight, the object will float. This is the principle used for boats.
Now here is a very simple experiment to test upthrust< /strong>
What you will need for your project:
2 polystyrene blocks, one double the size of the other A tank or a bowl of water A wooden block A MarbleMethod for this easy science fair project to do with the kids:
Place the two polystyrene blocks in the water Notice that they float because they are made of very light material So, for them to float only a small amount of upthrust is needed Now you can try to push them under the water You should be able to feel the upthrust pushing back Place the wooden block in and you will notice that it floats deeper in the water because it is heavier or denser than the polystyrene blocks Now drop the marble in, you will notice that it sinks immediately as the upthrust is not enough to keep it floatingWhen doing a project such as this, remember to make notes of all your steps and to take photos for your display. It is also important to make use of the proper scientific method to make sure you do a good project.
In this project, what would you say is your hypothesis? Which part of this experiment is your control? How would you describe your method?These are some of the things you will have to know if you want to do a winning science fair project. Even easy science fair projects to do with the kids, needs to adhere to this as they have to learn from the very beginning to do it correct.
The next easy science fair project to do with the kids..
Making use of the upthrust with a hollow hull
What you need for this experiment:
A pair of scissors Kitchen foil about 20cm X 15cm Kitchen paper towels The same tank of water MarblesHow to do this easy science fair project:
First of all place the flat piece of kitchen foil in the tank Give it a slight push and notice that it sinks with the slightest push because it does not replace a lot of water, so the upthrust in minimal Remove the foil from the water and carefully dry it with the kitchen paper without tearing it Now you have to carefully, without tearing the foil, model it into a simple boat shape with your fingers Place your boat in the water What happens? Why does it happen? Now start filling your boat with marbles, as your cargo What happens now? Why does it happen? How many marbles can you place in your boat before it sinks? Why does it eventually sink?In answering these questions, think of the experiment above. Now you have demonstrated how a boat works. Even though it is made of metal, it is filled with a lot of air and this creates enough upthrust to make it float. If the boat is overloaded though, it will eventually sink.
