Week 4 This week I learned about the external anatomy of a frog. The external anatomy of frogs show lots of adaptations. Their long legs alow them to jump far aways from preditors and helps them swim fast. Frogs have sllimy skin with allows them to breath through their skin. They have covering over their eyes so they can see in the water. They have a big mouth so they can swallow their prey whole. As you see, frogs are a well adapted to their enviorment.

Also, this week I learned out the frogs internal anatomy. The internal anatomy is simalar to the humas internal anatomy. The frogs liver, though, is te one of the bigest organs in its body. This organ helps digest the the food the frog eats. The stomach also helps digest food. Then the smaller intestine, which is as long as the frog its self, large intstine, and then finally the rectum. So that proves frogs are the same as humans.

Next week I would like to learn about all the different adaptations that animals have in this community. Some adaptations in a mouse are long legs, big nose, thick fur, and huge ears. Same with horses, elk and deer. Mountain lions have good site, keen sent, great refleces, warm fur, and sharp claws. Many other animals have adaptations which helps them survive in the wild and catch prey.

Week 3 This week I learned about the different types of energy form. The first energy form is kinetic energy. Kinetic energy is sound(compression waves), motion(moving objects), thermal (vibrations of atoms), radiation (electoromagnetic energy), and electrical (movement of electric charges). Potential energy is stored mechanical, chemical, gravitaional, and nuclear. Kinetic energy is being used and potential energy can be used.

Week 2 This week I learned lots of things. I learned about metals, nonmetals, and metaloids. Metals are good contucters of electricity and heat, they are on the left side of the P. Table, and they have few electrons on their valence shells. Nonmetals are on the right side of the P. Table, they almost completely fill their valece shells, and they can not conduct electricity or heat very well. Metaloids have the fewest elements on the P. Table.

This week I have also learned about how different elements react to the same acid, if the elements are maleable or brittle, and I learned the different colors and textures of different elements. Only three elements reacted to the acid, only two were maleable and didn't crush, and they all had differnet colors and textures. Zinc, Magnesium, and Bismuth were the elements that reacted, and Copper and Magnesium were the ones that were maleable.

Next week I want to learn more about grouping the elements. I want to learn about all the different properties and charicteristicts. I want to do new labs with the elements and figure out which ones will blow up with others. Hopefully I can figure this out by the fourth of July and scare all my friends. I want to learn about nobal gases and how they work. Maybe I will learn all of tthis next week.

 * Week One.**

This week I learned lots of things. I learned mainly about valence shells. Valence Shells are energy levels that surround the nucleus. Each energy level can only hold a certian amount of electrons for example: The first energy level can only hold 2 electrons, the second can hold 8, the 3rd can hold 8, the forth can hold 18, and so on. You can tell how many electrons there are in the atom through how many protons there are in the atom.

Last week I learned all about the atom. The atom has a nucleus that consists of protons and neutrons. To tell the atomic mass, you have to take the number of protons and add the number of neutrons. If you subtract the atomic mass from the number of protons then you will get the number of neutrons. J.J. Tompson found that atoms have negitive charges in them because negitive charges are atractive to positive charges.
