Refection about the Movie about Dirt

In science class my class and I have watched a movie about soil. The movie has explained how soil contains today much more toxins than before because of pollution. Soil contains all of the kingdoms (Animal, plant, fungus, Protists, and Bacteria) which means that soil is very valuable and productive. Soil has been used other 3000 years for a variety of things like building houses or pottery. Soil is the main material for agriculture and planting. Slowly the soil is been even more polluted which the underground waters take to the closest body of water and pollute it again with the same toxins and poisons. Thus, many species of fish has died because of this pollution , but only jellyfish can survive living in these conditions. The movie is explaining he idea that soil is being lost because of not paying attention. On the other hand, they did not explain the other idea they have leaned too much on one idea and have neglected the idea of why are polluting the soil why. The movie did not explain this idea. In my opinion we are polluting soil because we are not even paying attention let alone undertake something for the soil which is the chemical of life.

Hot Chilly Pepers can Help to Prevent Allergies!

The study, which appears in the August 2011 scientists ,have found out that hot chili peppers, which are known for their spiciness and about "tearing out" people, have came up that on a contrary hot chili peppers can help with allergic symptoms like: a stuffed nose, tiered and red eyes, and choking.   Scientists say that hot chilly peppers clear mostly all of the parts when having allergies. How do hot chilly peppers clear out parts of our body that are endangered by allergies? Well this is a good question. Hot chilly peppers with their strong smell clear and mostly disinfect the nose and lungs. In order to disinfect the lungs by the hot chilly peppers is a bit disturbing. Hot chilly peppers have to have their strong smell and taste in order to disinfect the body parts. To disinfect the lungs and esophagus you would have to swallow a piece of the chilly peppers. On the other hand, for the nose you would have to smell the piece for a while.

What Scientific Activities have I did this Summer

During this Summer I was the whole time in Monte Negro. Up in the mountains where there is a lot of rocks i got an idea to start making a little wall of stone. However, to support that big stone wall or just a stone on top of a stone, there has to be either cement or concrete. This was a lot of fun for me, mixing water sand and cement which is almost as like cemestry. to get this hard and supporting substance you have to mix thse 3 substances which are water and cement  and sand. This typeof a substance is a conpund substance which mean that 2 or more elements give one more element which is the third one. How does this form? Easily, the molecules in the whole 3 substances integrate and form the thirs compound substance this is how it works. But if there is any element from these 3 missing then it wont make the concrete nor it will be supportful nor it wont be a conpund substance but it will be just a mixed substance. After wards I used the cement to stick the stones on top of each other, and it will last who knows up to when.

Goals For this Year in Science

I am back from my holydays and now I am 7th  grade. Now I have to make new goals for this year. My goals in science class this year are:

1. To be better in physics this year.
2. To be even more better in tests and earn even better grades.
3. And to study more and better for tests and to be more efficient more while doing tthis year.

Today we have done an interesting experiment. Measuring the movement of the balls made out of different materials powered by human breath. We used a Styrofoam ball, a big marble, a small marble, a ping pong ball, a golf ball and a tennis ball. For blowing, we used a straw and we blew with our normal breath, with a middle strength breath, and with a hard breath. We taped a ruler on a desk so we can measure the length of every ball's movement. Here are the results: with a normal breath the shortest length was traveled by tennis ball; with a normal breath the longest length was traveled by ping pong ball; the tennis ball traveled the shortest distance when powered by middle breath; the ping pong ball traveled the longest powered by the middle strength breath; the hard strength breath moved the tennis ball for the shortest length and ping pong ball for the longest length; normal breath didn't even move tennis and golf ball. What we have learned is that movement of an object is always related to its mass and the amount of energy - force needed to create its movement.

KWL Forces and Motions

In science class we have began a new unit which is called forces and motions. I don't know much about forces and motions, in second grade I have learned about gravity which is a force on planet Earth how it pulls everything to the earths surface. but  since then and on haven't learned much about gravity so I'm looking forward to learn more about forces and motion. I have also some specific questions about this unit like what is motion? How does motion effect people? How many forces are? How many motions there are? What is effected by forces and motions?
