====science is a very fun subject. its one of my favorites. Science to me is a mixture of adventure and mystery, but lets get to the real definition. Science is a study of nature, our world and the far reaches of the universe. Science teaches us about things in the world such as electricity, molecules, erosion, the water cycle, etc. Science is pretty much the study of the natural world through observation and logical reosoning, such as marine biology, the study of under water life, scientist who study pretty much ALL of the natural world, archeologists who study what has happened in the past, such as the extinction of dinosaurs. I can go on and on and on. So science is a very complicated yet very fun subject to me and it will help me understand alot on how things happen in the Real World. It can also help us create new inventions for the future, and can also help us on how and why things happen, and how it can and or will happen in the FUTURE.Science also helps us power our way through hard situations such as hurricanes and violent storms by scientists studing what the humidity and stuff like that is like so that the can let us know. Science also helps us with providing us with electricity to power our electronics such as tv's ps3's etc. as you can see science is in pretty much our ENTIRE life so science is VERY, VERY, VERY important to most of us but it should be ALL of us, and we can start by paying attention to our environment and pollution because before we know it we could be back to the caveman ages and we might even kill ourself's by killing all the trees in forest's and stuff. So remember science is about the natural world so we have to take care of it.====

====heyy guyz it's Dru here. my hobbies outside of school are playing video games and playing football with my friendz. 1 reason why i like scince is because it really helps me know about why everything happens the way it does. .What i look foword to learning this year is ELECTRICITY.Thats all for now so I see you guyz later!!!!!!!!====

Heat retention- Does salt water hold more heat than freshwater?

__Thermal Energy__
Thermal energy is an example of kinetic energy, and is the temperature of the inside of an object. It is an example of kinetic energy because of the uneven moving of particles, creating temperature. This will probably be the main factor of this project.Thermal energy is very very small, that its not visible by the human eye, but it visisble be scientific machine. So obviously this is a very important factor.

__Saltwater__
salt water is ussaly found in beaches and oceans, so thats probably going to be my sorce of saltwater. Saltwater is the mixter of water and broken down rock thats been broken down.
