ElectricityElectricity is the movement of electrons. We use

electricity is everyday things and is a vital source of power that we need. Examples is a house, light

bulb, and to power other appliances.

WavesWaves transfer energy with or without a

medium. Examples are putting on bed sheets, an earthquake and a flag being blown in the

wind.

Electromagnetic WavesElectromagnetic waves transfer energy

without a medium. Examples are radio waves, X-rays, infrared rays and visible light.

ColorColor has 7 different wave lengths that is in

visible light. They are red, orange, yellow, green, blue, indigo and violet. Black absorbs all

wavelengths and white reflects all wave lengths.

The EyeThe eye has two different types of cells that are

called rod cells and cone cells. Rod cells let us see shades of gray and cone cells lets us see primary

colors. It has the cornea, optical nerve, the retina, and the iris.

Conductors and InsulatorsA conductor is a substance that allows electricity and

heat to pass through. Examples is copper, iron and metal. An insulator doesn’t allow electricity and heat

to pass through. Examples is rubber, plastic and wood.

LightningLightning first starts inside a cloud that starts to build

up protons and electrons. They then are separated and the protons are on top and the electrons are at the

bottom. Lastly, the electrons create an electric charge and is released onto the Earth.

ForceThis is what we everyday people use to move

or stop objects. In order stop an object, a force is required to stop it.

Physical and Chemical Change

A physical change is when you change an objects appearance and examples are folding paper, and writing on paper. A chemical change is when you

change a object and it becomes a new substance and examples are burning paper and moss on rock.

MixturesThese are when two or more objects are

physically combined. The particles are able to be seen. Examples are salad, salsa, and rocks

w/ water.

Solute and solventA solute is the object that is being dissolved and

examples are M&M’s, tongs, and skittles. A solvent is the object that is doing the dissolving

and examples are water, acid and juice.

Physical and chemical properties

Physical is something that describes an object and examples is a red door and a blue pen. Chemical

properties is something that describes a chemical change. They are three properties that describe a chemical change

and that is flammability, combustion, and reactivity.

Kinetic and potential energy

Kinetic energy is energy that are in motion. Examples is swimming, and someone that is sliding off hill.

Potential energy is that is being stored, Examples is someone getting ready to dive and someone getting in

position to run.

Newton’s LawsNewton’s first law is anything that is moving can be

stopped by applying force. Newton’s second law is the more mass something has the more force you need to

apply. Newton’s third law is something has an equal and opposite reaction when you use force.

SolidA solid is one of the three states of matter.

The particle arrangement in a solid are tightly packed together and not moving. Examples of

solids are a desk, a chair and a wall.

LiquidA liquid is one of the three states of matter. The atoms of a liquid are that they’re close

together but they are still moving. Examples is water, milk and juice

GasA gas is also on of the three states of matter.

The particle arrangement in a gas is that they’re spread far apart and they are moving.

Examples of gas is helium, smoke and air.

Homogenous MixturesA homogenous is a mixture when you can’t

see the particles. Examples is soda, milk, juice and tea.

Heterogeneous Mixtures Heterogeneous mixtures are mixtures when you can see the particles. Examples is salad,

salsa and rocks w/ water.

CompoundA compound is two or more elements

chemically combined. Compounds are found everywhere. Examples are water, humans, a

computer and a desk.

ElementAn element is a pure substance that is made

up of its own atom. Elements are naturally made but they can be man- made. Examples

are oxygen, helium and gold.

InfrasoundInfrasound are very low sounds that cannot be detected by the human ear. Animals that

use infrasound are whales and elephants.

UltrasoundUltrasound are very high pitch sounds that

cannot be detected by humans. Animals that use this ability are bats, cattle and dogs.

ReflectionReflection is when light waves reflect off an

object. Examples are some ponds in water and mirrors.

Parts of an atom There are three types of an atom it is the proton,

neutron, and electron. The proton is in the nucleus and is a positive charge. The neutron is also in the nucleus

and it is both a positive and a negative charge. The electron is outside the nucleus and is a negative charge.

OpaqueOpaque is when you cannot see through an

object. Examples are a door, a table and a computer.

TranslucentTranslucent is when you can only see the

shape of an object. Examples are a fog, frosted class and vinegar.

Transparent Transparent means that you could see

through an object. Examples are a window, a mirror and water.

Melting PointA melting point is when a solid is melted into

a liquid. Example is ice melting into water.

Freezing PointThis is when a liquid is turned into a solid.

Example is water freezing into ice.

Boiling Point This happens when a liquid is turned into a gas. Examples is water boiling and turning

into steam.

SublimationSublimation is when a solid is turned into a gas. Example is dry ice turning into carbon

dioxide.

CondensationCondensation is when a gas is turned into a

liquid. Example is a cold drink on a hot, sunny day.

LightLight is something that makes things visible for other objects

such as a light bulb. There are many different kinds of light like X-rays, infrared rays, UV rays, and visible light. Like waves,

light has wavelengths but they are not specifically considered waves but instead they are considered electromagnetic waves.

CommentsThis assignment is the longest PowerPoint that we’ve done so far. It’s

really a lot of work that Mr. A. has taught us just for one semester. All these slides that I have done isn’t even all the work that Mr. A.

has done. I really learned a lot of stuff this semester some of it was so much that I don’t even remember. I have to give credit to Mr. A for

all the stuff that he planned for us for just one semester,
