Parts of an Atom 12-5-16

1st Verse: They’re tiny and they’re teeny, Much smaller than a beany, They never can be seeny, The Atoms Family. Chorus 2nd Verse: Together they make gases, And liquids like molasses, And all the solid masses, The Atoms Family 3rd Verse: Neutrons can be found, Where protons hang around; Electrons they surround Chorus: They are so small. (Snap, snap) They’re round like a ball. They make up the air. They’re everywhere. Can’t see them at all. #18.Atom’s Family Success Criteria: I can recognize that all matter consists of atoms.

How can the student best test the strength of the generator? a. place a magnet on a spring scale and record the force of the magnetic field b. place the generator on an electronic balance, and record its mass in kilograms c. connect the generator to a circuit that contains appliances and then observe if the appliances work.

6. Technicians plan to develop a new type of keyboard that will have alphabet letters in different positions from a standard keyboard. Which will best help the technicians decide if the new keyboard is an improvement over the standard one? a. analyzing the problems that people have using standard keyboards b. asking people their opinions of how they like standard keyboards c. comparing the speeds at which people type on each style of keyboard

7. All too often, modern technology items end up being thrown away once newer and faster models are available. Which example of modern technology shown below can harm the environment? a. Disposing of old computers in landfills where toxic chemicals may leak into the soil b. Designing more efficient car engines that burn less gasoline per mile c. Using cloth bags at grocery stores instead of using throw-away plastic bags

Learning Intention: I can identify the subatomic parts of an atom I can recognize all matter is made up of atoms. Success Criteria: I can list substances in the classroom that consist of matter with my neighbor. I can name the parts of the atom and their charges. I can draw an atom and label the parts in a foldable.

Brain Pop!!!

Atoms Foldable Atoms Atoms- The smallest unit that an element can be divided into and still be the same substance. All matter is made up of atoms. Matter is anything that is a solid, liquid, gas, or plasma.

Proton Positively Charged (+) Inside the nucleus The other ½ of atom’s mass #Protons= Atomic # (Element’s Identity)

Neutrons Neutral particle NO charge (0) Inside the nucleus ½ of atom’s mass Keeps protons together Neutrons= Atomic mass- Atomic #

Electrons Negatively Charged (-) Outside the nucleus in the electron cloud No effect on atom’s overall atomic mass. Responsible for ability to form bonds.

Things that are not made of matter Ask yourself if it is a solid, liquid, or gas. Example: Time is not made of atoms. Time is not a solid: You can not touch it Time is not a liquid: You can not drink it. Time is not a gas: You can not smell it. Example: Energy is not made of atoms Energy is not a solid Energy is not a liquid Energy is not a gas Example Force is not made of atoms Force is not a solid Force is not a liquid Force is not a gas

Be More about Atoms 4 Legend 9.0 =protons =neutrons Beryllium Success Criteria: I can recognize that all matter consists of atoms. More about Atoms We once thought atoms were the smallest particles. We now know there are even smaller particles They are called sub-atomic particles Notice the sub-atomic particles in this beryllium atom It has 4 (blue) protons (So the atomic number is four) It also has 5 (green) neutrons and 4 (orange) electrons 4 Legend =protons =neutrons Be Beryllium 9.0 =electrons
