Week#2_Prompt#3

Heating a pot of soup will overflow because the soup is in the process called thermal expanison. The pot that they are using is made of metal, which is a good thermal conductor, and on that point the temperature is rising really fast. Thermal expansion is when the temperature is increasing, the object is expanding. For example,when you leave the car outside, the heat is rising up in the car which is making the car expand. That is how heating a pot of soup can make the soup overflow

Week#1_Prompt#2

What happens when the ball is about to go down, it has potental energy. Now based in my reasearch, potental energy is when you are holding the energy inside the object. When you let go of the ball and that it bounces, that is kinetic energy. From my reading, it says that the kinetic energy is when the object is moving which is the moving energy. Also in my reasearch, I found when all of that is mixed together, you get the mechanical energy

Technology in Science

The reason why I like science is because it has so many things in math which is the subject I why the most. They have equations and it also has cool labs and chemicals. The last reason why I love science is because in science, I get to explore new thing s that I have never learned before. The reason why I like technology is because it makes life so much easier. Another reason why I like science is because with technology, there some many thinge we can accomplish in so little time with technology.
