Week 1 April 13th 2009 1. This week and last week I learned how to read a periodic table and how to draw a Bohr model of the element in the table. The middle big letter or letters in the middle of the colored box is the chemical symbol with a certain color showing the physical state. Also just below the symbol of the chemical shows the full element name. The colored box surrounding the numbers and letters represents the metals, metalloids, and nonmetal. On the bottom of each individual box i the atomic mass. Towards the top of the small box it indicates the atomic number.

Week 3 April 23rd, 2009

1. This week we learned about the different forms of energy. There are two main types of energy are potential and kinetic. Kinetic energy is the energy of motion. Potential energy is stored energy. Gravitational, stored mechanical, chemical, and nuclear are all types of potential energy. Thermal, radiant, sound, motion, and electrical are all types of kinetic energy. In class together we made a web about these different types of energy forms for our notes and it really helped because the chart stuck in my mind. 2. Also we learned how to balance equations. The topic was mainly known as the conservation of matter (mass). We did a quick lab on this that helped us explain the law of conservation of matter. The law states that "Matter can neither be created nor destroyed by ordinary means. It can only change forms." We studied mostly on this subject is science class and it was also pretty rememberable for me.

Week 4 May 11th, 2009 1. Earlier this week I learned a lot about volume and mass of things. Going into more detail we looked at Newton’s law of gravity and movement. In an experiment we used a wooden ball and a steel ball. We pushed the two with a book with the same amount of force. The wooden ball of course went further because the mass was less. The steel ball had more mass which made it slower that the wooden ball. 2. This week, during our frog dissection I learned quite a lot. The whole lab was really interesting I thought, although the smell and touching the organs inside sort of grossed me out. First of all things that really stuck in my mind was the purpose and placement of all the organs inside. The most important organ is obviously the heart. It’s about two centimeters above the liver. The liver, which was located closest to the chest of the frog, is the largest organ in the body and very important also. Just underneath the liver lies a small sack called the gall bladder. Its job is to collect the bile. Then below is the gall bladder is the stomach (sort of in a J shape once you lift up the liver) which is connected to the esophagus taking the food of the frog to the stomach to be broken down into waste. Once this all happens it is taken in though the intestines. These lead to the cloaca or the rectum. These take the waste out of the frog’s body. Behind this system is two more, both the urogenital and repertory systems. The urogenital system transfers the urine to the bladder and out. And the repertory system takes the air into the lungs which are located almost under everything. Obviously fat bodies are around the organs to keep them from damaging others. There are more things inside too but too many to list.
