Final Science Review
Lab Safety
• Be able to indentify Unsafe events
and know how to correct them to make a safe lab environment.
1. What unsafe things do you see?
2. What would you do differently to make this lab safe?
Scientific Inquiry
• Apply the steps of the Scientific MethodThe animals that live in Martin’s pond are dying as the pH levels are in the acidic range. However the animals that live in Potter’s pond are fine and healthy. 1. Both ponds are only 1 mile apart from each other.2. They receive the same rain fall3. They both are same size in surface area.
Scientific Inquiry
• Apply the steps of the Scientific Method1. What question can you test by doing an experiment?
2.What hypothesis can you come up with?
3. What data can you collect to support your hypothesis?
Chemistry
• Know these terms:– Atomic Mass- Protons + Neutrons– Atomic Number=Protons=Electrons– Protons- + particle in the nucleus of an
atom–Neutrons- no charge particle in the
nucleus of an atom– Electrons- - particle located in energy
levels around the atom.
Chemistry • Know that the :– Periodic Table is in order of increasing
atomic number from left to right.– Put these atoms in order
Chemistry• Be able to identify which elements will
combine together.
• Goal is to get 8 outer electrons.• http://www.youtube.com/watch?v=5IJqP

Geological Time• Know the term Uniformitarianism-
the present is the key to the past.• They way landforms form today is
the way they formed millions of years ago and will continue to form in future.
500 Million years ago Today 500 Million years from now
Geological Time• Know that environments change over
time and animals need to adapt to fit their environments.
• http://www.youtube.com/watch?v=YX8VQIJVpTg
• Describe the environment for these animals.
Earth Layers
Remember this and you’ll be fine.http://lightspeed.fort-dodge.k12.ia.us/safevideos/Video.aspx?id=Q9j1xGaxYzY
Plate Tectonics• Know that convection in the mantle
causes the crust to move.• http://www.youtube.com/watch?v=xE
YLx_bhtoA• What do you think would happen to
crust movement if the material in the mantle was hotter?
Plate Tectonics• What do you think the Earth would
look like if convection and plate tectonics did not occur?
Plate Tectonics• Use these words to fill in the paragraph
below.Tension, Seismic Waves, Rock Layers,
Convergent Boundary, Transform Fault Boundary
When two plates come together at a _________ ________ they build up __________ .When the two plates slide past each other it sends ______ _______ through the ______ ______ and creates an earthquake a long a ________ ________ _______.

Rock Cycle
Rock Cycle
• What do we use rocks and minerals for?
Rock Cycle
Atmosphere and Weather• Know that following:– Gravity keeps the atmosphere in place.– Therefore the greatest concentration if
air molecules in located closer to earth/ground.
Atmosphere and Weather
1. What type of pressure system is near Texas? Low Pressure
2. What type of weather does this bring?Bad / Changeable weather
Atmosphere and Weather
1. What type of air mass is moving south through Iowa?Cold Front, cooler and drier air
2. What happen to the temperatures and weather in Iowa over the next few days?
More cold fronts so temps. will stay cool and no changeableWeather due to high pressure systems.
Atmosphere and Weather
• Know why tornados and thunderstorms commonly form over the Midwest.
• Know that the sun heating the Earth unevenly causes weather.
• Know that the tilt of the Earth on its axis produces the seasons.
Atmosphere and Weather• Know that the tilt of a planets axis produces
seasons.
Our Solar System• The Inner Planets–Mercury–Venus (Earth’s Twin)–Earth–Mars
• These planets are called the rocky metallic planets.
• They are smaller and form closest to the sun.
Our Solar System• The Outer Planets– Jupiter–Saturn–Uranus–Neptune
• These are called the gaseous planets.
• They are larger and form furthest from the sun.
AstronomyKnow that….
1. A day on each planet is not the same, they all
rotate around their axis differently
Mercury 59 daysVenus 243 daysEarth 23 Hr. 56 min.Mars 24 hr. 37 min.Jupiter 9 hr. 55min .Saturn 10 hr. 39 min.Uranus 17 hr. 14 min.Neptune 16 hr. 7 min.
The Universe• The Big Bang Theory
–A theory that says the universe began from an extremely hot and dense state about 13.6 billion years ago.
–The universe has been expanding ever since.
How will the Universe end?2. An expanding universe- The universe
is expanding and it’s speeding up.Eventually it will over come the force of
gravity and it will not contract back into a small point of hot energy and matter.
Over trillions of years the universe will grow cold and die out.
Astronomy
• Know how objects from space have affected Earth’s geological and biological history.
