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.
