One thing that I learned in science class this week was how to dissect frogs. When dissecting frogs I learned that when cutting it open with scissors you have to pull up so that you don’t damage the organ. The frogs that we dissected this week were leopard frogs. The frogs tongue is connected to the front of the frogs mouth so that it can catch pray easier. The biggest organ in the frog was the liver.======

A interesting thing that i discovered this week was that small intestine is longer than the frog; the frog was 10cm and the small intestine was 12cm. Also the frogs forelegs only had 4 toes instead of 5 like the hind legs. Frogs have 2 pars of teeth vomerine and maxillary. The vomerine teeth holds prey and the maxillay teeth rips the prey. Another thing that i discovered was the the eggs go through the oviducks.======

23 April, 2009 One thing that i learned in science this week was the forms of energy. There are two forms of energy, kinetic and potential. Kinetic has 5 forms of energy thermal, electrical, sound, radiant, and motion. Potential has 4 forms of energy stored mechnical, nuclear, gravitational, and chemical.

A interesting thing that i learned is balancing equations. When balacing equatons you have to have the same number of carbons and reactants.

April 13, 2009 One thing that i learned in science this week was how to draw Bohr modles using the atomic number and atomic mass. I also learned that the first shell can only hold two electrons, the second can hold eight electrons, the third holds eight electrons too, the fourth can hold eighteen electrons, the fifth can also hold eighteen electrons. Another thing that i learned was parts of the Periodic Table. A part of the periodic table is metals. Another part of the table is nonmetal. Also there is metalloids in the periodic table.

A intresting thing that i discovered how to do this week was how to draw Bohr modles. Bohr modles can be drawn for all of the elements. Bohr modles aren't the easiest things to draw as I learned, but after a few days of practicing I learned how to draw them correctly. Bohr modles have shells the first are just called shells but the last one is called the valence shell. That is one interesting thing that i learned this week in science.

Something that i don't get is how to draw ions. Drawing ions is confusing because you have to see whether the compond loses or gains electrons. Also because you have find the element symbol. Another reason that ions are confusing is because of the superscripts and the subscripts.
