5/15/09 week 4

This week we did dicechtion of frogs and It was fun. We learned where everything is in the frog, like the stomach is under the liver and connecting to the small intestine, and the heart is under the liver and the heart has three chambers. In the female it has the overy sack that holds the eggs and ostium is on the top of the colled tube.

4/23/09 week 3 This week we leard Forms of Energy like Kinetic Energy-energy of motion and Potential- stored energy or energy of position. Kinetic has electrical, radiant, Thermal, Motion and sound. Potential has Chemical, Stored mechanical, Nuclear and Gravitational. Also Energy is the avility to do work. Law of Conservation of Energy can neither be created nor destroyed. Can only change from one form to another. Ex. Carturns stored chemicla energy into energy of motion. 4/13/09 week 1 Last week I learnd about how atoms are made. In the nucleus there are protons (positive charge) and neutron (no charge). Atoms also have electrons, they have negative charge. They're found in electron clouds or shells. Each, energy level holds a certain number of electrons. I think I'm still a little confused on how to read the Periodic Table.

4/17/09 week 2 This week we leard about making compounds. Compounds are 2 or more different elements. Also when you wright the ion, witch is a atom has an electrical charge, you write the superscript- a # written above and to right of symbol to show ion's charge. Then when you write the formula like Calcium Chloride CaCl2 you put the subscript - a # written below & to right fo a symbol to show how many of each element you have in a formula.
