Making Molecules Summative

Molecules are made up of different elements connected by bonds which are shared electrons of the atoms.Molecules are something that are very important to learn about. If we understand molecules we can know how to manipulate objects for the better. We can create new technologies and invent new things that will completely revolutionize this world. We can manipulate cancer molecules and create a cure for it and other diseases. This molecule is important because it is used to fertilize plants so they grow faster and better. Sulphuric acid is also important because it is used to wash out impurities out of gasoline to make it less dangerous in the motor.

Particles Behaving Strangely

Clothes dry at room temperature because the particles of water on the clothes are always moving because a water particle is a group of molecules always moving together. As the particles start moving off the clothes, the gas particles, which are always moving randomly, mix with the water particles and take them off the rest of the way.

In this picture you can see the yellow particles ( the water particles) mixing with the blue particles ( the air particles )

Liquids boil at a lower temperature when they are at a higher altitude because there is more are pressure in a lower altitude. So, the pressure from the air particles don't let the water particles move out of the kettle. They need more energy from the heat to escape. When there is little pressure the water molecules escape easily so the boil faster. They need less energy from the water to escape.

Here is a chart comparing both altitudes.

We can smell things around corners because particles from the solid are always moving so some move off the food and stick into our sensors in our noses. So, the brain identifies the smell and sends a signal to the nose.

Here you can see the red particles from the pizza moving from the pizza, mixing into the air particles and then sticking to our sensors.

My phenomenon:

A bathroom is hot after a shower because the hot particles from the water have more energy so they move from the shower into the glass and the walls. The air particles and the hot water particles mix and create a warm and dense particle.

Potential and Kinetic energy

Potential and Kinetic energy are how everything around us works, moves and transforms the world. 

Potential energy is energy stored inside an object. An example of potential energy is a loaf of bread because the energy in the bread isn't moving inside it. Kinetic energy is moving energy. An example of kinetic energy is a running person because it is using energy that is moving while he is running.

Energy has many forms. Some forms of energy are mechanical, heat, sound and chemical energy. 

Energy cannot be created or destroyed, but it can be converted from one form to another form. For example, in a laptop electric energy from the plug converts into sound and light energy when the laptop turns on.

In order to understand ourselves better, we need to understand what our body is made of, which is energy. With the knowledge of understanding energy we could invent new things because everything is made of energy. We could predict what is going to happen with the earth. These things couldn't be done without understanding energy.

Analyzing energy

Today in class we did something very interesting. We used tracker to understand how different types of energy appear in a cart. I learned that the kinetic energy of an object affects the speed in many ways. We saw in the velocity graph that when the cart was moving down the ram it was gaining speed but when it got to the bottom it started to decrease. We also saw in the kinetic energy graph that it was the same. When the cart was moving down the ramp the energy was increasing and when it got to the bottom it started to decrease. We can conclude that the velocity comes from the gravitational energy of the cart converting into kinetic and/or mechanical as it moved down the ramp  so it gained more velocity. When the cart got to the bottom of the cart it decreased because the cart didn't have any gravitational energy to convert into kinetic so i started to lose the velocity.
