1: Jesus Arenivar | 8th grade | Mrs.Reid | 2nd period

2: Laboratory Safety Rules | Lab safety is very important. Now that I know what to do these safety rules will help me in the future. Lab safety is important to me because I can get hurt if I do not do the right thing. I will use these safety rules when I am at home because sometimes I will be using the same kind of chemicals at home. This unit has really taught me how to be safe in a lab. | Hazard- A danger in the science lab that should be reported to the teacher | Precaution- Steps taken by a student to be safe in the science lab | Waft- The way to smell things in a science lab; it is done by cupping your hand and fanning the smell towards your nose | Flammable- Easily set on fire | corrosive-destructive; steadily harmful | How can you use these lab safety rules in real life?

3: Periodic Table | The periodic table is very important to scientist all over the world. It has all the elements known to man, but theres still more to discover. The table classifies the elements by their reactivity, valence electrons, and other propeties. There are groups and periods which also classifies the elements. | valance electron- an electron in the outermost energy level of an atom | periodic law the properties of elements tend to repeat in a regular pattern when elements are arranged in order of increasing atomic number | period a horizontal row of elements in the periodic table group a vertical column of elements in the periodic table | Element cube- it contains all the information about an element to its name and mass | Will they ever find more elements?

4: . | Newton's Laws | Newtons three laws have explain many things about motions in our everyday life. They explain why things move and why things stop. Coming from a man born in the 1400s. Without these laws Einstein couldn't have come up with his theories. | Balanced Forces When two or more forces are exerted on an object, if their effects cancel each other out and don't change the object's velocity | Force It is a push or a pull Friction The force that brings nearly everything to a stop Net force The combination of all the forces acting on an object | Unbalanced Forces If the net force is not zero

5: Electromagnetic Spectrum | THe electromagnetic spectrum is The entire range of radiation extending in frequency from approximately 1023 hertz to 0 hertz or, in corresponding wavelengths, from 10-13 centimeter to infinity and including, in order of decreasing frequency, cosmic-ray photons, gamma rays, x-rays, ultraviolet radiation, visible light, infrared radiation, microwaves, and radio waves. | Wave-A disturbance that transfers energy from one place to another. Wavelength-The distance between two corresponding parts of a wave. Crest-The highest part of a transverse wave. Trough-The lowest part of a transverse wave. Amplitude-The distance between the rest position and the highest or lowest part of a wave. | Why cant we see some wavelengths?

6: Weather and Climate | Wheather and climate are two different things. Climate is the weather r of a place for a long period of time.Weather the state of the atmosphere in terms of such variables as temperature, cloudiness, precipitation, and radiation. Both still are affected by the sun and theres different weather climate all over the world that affected us in everyday life. | atmosphere-The blanket of gases that surrounds Earth air mass-A large region of the atmosphere where the air has similar properties throughout land breeze-Wind that blows from land to sea sea breeze-wind that blows from sea to land precipitation-Any form of water particles that falls from the atmosphere and reaches the ground | Why does weather change over millions of years?

7: Environmental Changes | Over millions of years the environment changes in many ways. It can happen naturally such as wildfire which changes the forest or and flood. Animals can also change the environment such as humans who pollute we can destroy a whole environment. So those are some changes that change the environment | Pollution-the occurrence in the environment of a substance or form of energy in concentrations large enough to have an adverse effect on people, their property, or plant or animal Wildfire- A large, destructive fire that spreads quickly Flood-An overflowing of water onto land Extinction-The state or process of a species, family, or larger group being or becoming extinct. Global Warming- The gradual increase in the temperature of the earth's atmosphere, believed to be due to the greenhouse effec | Will the environment ever stop changing?

8: Reflection Page | One left page in my interactive notebook as i feel are my best work is the chemical and physical change page. I used very detailed colors and little notes telling me what the drawings were. The colors weren't just random the showed what color the objects were and had meaning. I think this shows my skills as a scientist as I know how to take notes and let see other scientist my work and they will know what everything is and means. | Another page i feel is my best work is the page where all our progress with our grades thorough the years. I can see how far I have progressed through the years with my work. This shows my understanding of science thus making me a better scientist
