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 Method The 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 fall 3. They both are same size in surface area.

Scientific Inquiry Apply the steps of the Scientific Method 1. 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. Y Y

The answers are … ElementAtomic # Atomic Mass ProtonsNeutronsElectrons Li37ABC O8DE8F AlG27HI Chemistry

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.

Geological Time Know that environments change over time and animals need to adapt to fit their environments. QIJVpTg QIJVpTg Describe the environment for these animals.

Earth Layers Remember this and you’ll be fine. dodge.k12.ia.us/safevideos/Video.aspx? id=Q9j1xGaxYzY

Plate Tectonics Know that convection in the mantle causes the crust to move. x_bhtoA x_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 ________ ________ _______. Convergent Boundary Tension seismic wavesRock Layers Transform Fault Boundary

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 changeable Weather 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 The Inner Planets – Mercury – Venus (Earth’s Twin) – Earth – Mars These planets are called the rocky metallic planets. These planets are called the rocky metallic planets. They are smaller and form closest to the sun. 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.

Astronomy Know that…. 1.A day on each planet is not the same, they all rotate around their axis differently Mercury59 days Venus243 days Earth23 Hr. 56 min. Mars24 hr. 37 min. Jupiter9 hr. 55min. Saturn10 hr. 39 min. Uranus17 hr. 14 min. Neptune16 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. Jmk&feature=results_video&playnext=1&list= PL F46B9DFCD Jmk&feature=results_video&playnext=1&list= PL F46B9DFCD
