Week 4 May 15 1. This week we disected frogs. we learned about their external, internal. We cut open the chest and evaluated a fen stomach, and the organs, the biggest was the liver. When we opened the stomach we found about nothing, but when we opened the large intestine we found a lot of undigested beetles and bugs. we also learnded the different stuff the frog eats. while we cut we found every part we were suppose too. 2 Later this week on disection we learned about the urogential system and brain. We found the testes and the bladder, kidneys and the oviducts, this was in a male but across from us someone had a female that had eggs under her stomach, this meant that the frog was ready to have babys. We cut the brain out of the rain and we did not succsessfully get the brain out without it getting smashed. 3. I would like to do the frog disection again it was very fun and gave me alot of knowledge.

Week 3 April 23

1. This week I learned about the different forms of energy which are kenetic, and potential. There are many different forms for each energy like for kinetic there are thermal, motion,electrical, radiant, and sound. Kenetic energy is the energy of motion this is energy that is moving. P Potential energy is stored energy, like a spring, some of them are chemical, stored mechanical, nuclear, and gravitational. 2.This week I also learned the conservation of matter lab. there were three trials each trial existed with vinegar, and baking soda. For the first trial we put the baking soda, and vinegar in a beaker then the reactants made the kleenax which the baking soda was in desolved. The second was put in a two liter bottle and it also desolved. The final trial was put in a flask and covered by a baloon, which was inflated. 3. This week I had a question on nothing i pretty much understould the deals.

Week 2 April 17

1. This week I learned how different elemnents are malleable and not malleable. We also add acid to the crushed elements to see the reaction. Same elements that were malleable were the iron, which stuck right to the hammer, the aluminum was totly flat. There were no elements that were malleable. The reactions to the acid was very interesting, most of the metals reacted. the reaction was like a fizzy sode it was like the element was desolving. 2.This week we also learned about compounds. Some stuff we learned about compunds was how they are formed, they are made by different elements That combine together. We did a worksheet how to connect compounds we hade to make a model, Then under the model we had to write the name of that compound, after we did this we had to write the Ions which tells if the elements had positive or negative charges, Then finaly we wrote down the formula. 3. This week I didn't totaly get the models we made of the number of electrons in an elements shell. I did not get how many electrons should go in a valence shell. I would like to know how to get the number of electrons in each shell, and how many shells each electron has this would really help me out.
