Animal dissections are often being used in schools. It allows a hands on experiment and not just looking at a piece of paper or a computer screen. It is also easier to see the body parts because you can move them yourself instead of looking at pictures. It also allows you to see the body systems and how they move throughout the body. These are the reasons that I think that animal dissections are used in schools.

Semester Project
K2
K2 is a mountain in the Himalayas. It is currently 28,251 feet high, making it the second tallest mountain in the world. I think that the mountain will continue to rise. The Indo-Australian plate still moves 67mm (6.7cm) every year. This would mean that the mountain is rising faster than it can erode.
How the Universe was Created?
I know that many people believe that the universe was created by a big bang and that its still expanding and many people also think that God created it. I think that God caused the big bang because the Earth was once a formless void. The proof is in Genesis 1 verse 2 “Now the Earth was formless and empty, darkness was over the surface of the deep, and the spirit of God was hovering over the waters.” That is how i think the universe was created.
What really happens in a chemical reaction?
For a chemical reaction to be classified as a chemical reaction, there has to be a new substance created. The reaction occurs when the electrons of one atom breaks off and joins with another atom. Temperature change, bubbling, and color change are signs that a chemical change has happened, but does not tell you what really happens.
Lab Safety
Lab safety is very important. Without it, people can get hurt. Always read the instructions before beginning the experiment. You don’t want to accidentally smell something you’re not supposed to. Never play around in the lab. You could spill a beaker of a poisonous liquid or burn yourself. Clean your station before you leave. You don’t want other classes to mess with the things or they could hurt themselves.
