Matter MattersPoster Project

Objectives0 Students will explain that atoms are the smallest unit

of an element and are composed of subatomic particles.

0 Students will analyze models of the scientific theory of atoms.

0 Students will analyze models and describe the motion of particles in solids, liquids, and/or gasses.

0 Students will explain matter.

Introduction/Task0 The work of numerous scientists over the course of

thousands of years has led to the development of the modern theory of atomic structure.

0 Individually or with a partner, create a poster that shares the important contribution scientist made to the development of atomic models and theories.

0 Begin your task by reading the following slides…

Atoms0 Matter is anything that takes up space and has mass.

All matter is made of atoms. 0 Atoms are the basic building blocks of matter. They

make up everything around us; Your desk, the board, your body, everything is made of atoms!

0 Atoms are too small to see without powerful microscopes.

Atomic StructureThere are two basic components in every atom:

Electron Cloud

Nucleus

Subatomic Particles

Three subatomic particles make up every atom:

Subatomic Particle Charge Location

Proton Positive (+) Nucleus or “Core”

Neutron No Charge (0) Nucleus or “Core”

Electron Negative (-) Electron Cloud

Subatomic Particles

Electron Cloud:• Electrons orbit the

nucleus.

Nucleus or “Core”:• Protons and

Neutrons are found in the nucleus.

Atomic TheoryChanges over time…

Atomic Theory0 Because we can not see atoms, we use models to teach

and learn about atoms. 0 The atomic theory has changed over time as new

technologies have become available.

0 Remember: Scientific knowledge builds on past research and experimentation.

Atomic Theory Timeline

Scientist Information Model

John Dalton

All matter is made of atoms. Atoms are too small to see, indivisible and indestructible. All atoms of a given element are identical.

Scientist Information Model

J.J Thompson

Discovered the negative electron, and predicted that there also must be a positive particle to hold the electrons in place.

Atomic Theory Timeline

Scientist Information Model

Ernest Rutherford

Discovered the nucleus of an atom and named the positive particles in the nucleus “protons”. Concluded that electrons are scattered in empty space around the nucleus.

Atomic Theory Timeline

Scientist Information Model

James Chadwick

Discovered that neutrons were also located in the nucleus of an atoms and that they contain no charge.

Atomic Theory Timeline

Neutrons

Atomic Theory Timeline

Scientist Information Model

Neils Bohr

Concluded that electrons are located in planet-like orbits around the nucleus in certain energy levels.

Scientist Information Model(Many Scientists!)The Modern Atomic Theory

Electrons do not orbit the nucleus in neat planet-like orbits but move at high speeds in an electron cloud around the nucleus.

Poster Time!Time to create your poster!It must include the following:__definition of matter__carbon atom and labeled particles__all scientists, their theories, and their atomic models from this power point.Be creative, colorful, neat, and organized!!

Content

ExcellentPoster includes useful

and relevant information on all required

components of matter, atom structure, and the

scientist and atomic model. Information is

well-organized and accurate.

GoodPoster includes relevant

information on most components of matter, atom structure, and the

scientist and atomic model. Information is

accurate.

FairPoster includes relevant information on some of

the components of matter, atomic structure,

and the scientist and atomic model. Some

information is inaccurate and poorly organized.

PoorPoster does not include relevant information or has few components of matter, atom structure,

and the scientist and atomic model.

Information is poorly organized and inaccurate.

Work Quality & Effort

ExcellentThe work done exceeds

all expectations and shows that the student(s) is proud of their work. It is clear that best efforts

were put forth.

GoodThe work was done with

good effort that shows what the student(s) is

capable of accomplishing. It is evident that time was

put into this poster.

FairWork is done with fair

effort, but the quality is still not what the

student(s) is capable of. It is evident that the work

was rushed.

PoorWork is done with little

effort, which resulted in a low quality poster. It is

evident that the work was rushed and little time was spent on the final poster.

Work is incomplete.

Style & Creativity

ExcellentPoster has an element of

creativity and style, and is not just a list of facts. Poster conveys a clear understanding of the

topic.

GoodPoster is clear and

contains few mistakes. Good creativity and

neatness.

FairPoster lacks clarity of

information, creativity and neatness.

PoorPoster does not convey a clear understanding of the subject matter and there are many errors. Poster is not creative.

Time Management & Behavior

ExcellentThe student(s) worked

great managing time and did a stellar job with their

behavior.

GoodThe student(s) worked

well on time management and did a nice job with

their behavior.

FairThe student(s) did not

work well on time management, but did

alright with their behavior.

PoorThe student(s) did not

work well on time management and had

poor behavior.
