Formation of the Solar System
Nebula- a cloud of gas and dust in space, the remnants of an exploded star.
Supernova- An exploding star, it crates a shock wave that could have nudged our nebula and started the formation of our solar system.
Collapse and Spin- As the cloud collapses it spins faster and faster. This causes it to flatten into a disc.
Sun Ignites- When the pressure inside the sun becomes great enough to cause nuclear fusion the sun ignites sending out a wave of solar wind that blows away the loose gas and dust.
6.1 Notes
Layers of the Earth (see notes from ch 3)
Continental Crust- Thicker and less dense than oceanic crust.
Oceanic crust- Thinner and denser than continental crust. Contains much more iron and magnesium.
Seismic Waves- Vibrations that travel through the planet during an earthquake. These vibrations are recorded by a seismometer and give us a picture of the inside of the planet, like a sonogram.
Continental Drift- The hypothesis that states the continents are drifting around and once formed a super continent (Pangaea).
Alfred Wegener- Scientist that proposed the continental drift hypothesis. pg 227
Evidence that supports Continental Drift
1- Puzzle Pieces (S. America fits next to Africa)
2- Similar fossils found separated by oceans
3- Similar geology and mountain formations separated by oceans
4- Signs of shifting location (fern fossils on Antartica0
The big unanswered question- What is the mechanism that causes the continents to move?
Answer- Mid-ocean ridge is where new oceanic crust is being formed.
Sea Floor Spreading- The oceanic crust is spreading from the mid-ocean ridge.
Magnetic Reversal- The Earths poles have flip flopped many times.
Magnetic Striping of the sea floor- The iron particles in the magma record Earths magnetic feild, creating a record of the magnetic reversals.
The age of the sea floor- Rock samples taken from the sea floor show the crust is oldest near the continents and youngest near the mid-ocean ridge.

The Changing Earth
The planet is estimated to be 4.6 billion yrs old.
It is constantly changing. The processes we see today have been
going on for a long time.
The Rock Cycle includes the weathering (breaking down) of rock and the erosion (transport) of sediment.
The 3 primary forms of rock are igneous, sedimentary and metamorphic.
See fig 2 pg 105 for rock cycle details.
Water Cycle includes the following 7 "tions"
evaporation, condensation, precipitation, percolation (soaking into the ground), respiration (animals), transpiration (plants), transportation (runoff)
Carbon Cycle includes the process of pulling CO2 out of the air (photosynthesis), and the release of CO2 by combustion (burning) and decomposition.
Nitrogen and Phosphorus are cycle between living organisms and the environment.

3.3 Notes
Heat Flow is the flow of energy from warmer material to cooler material.
Nearly all the energy on the planet comes from the sun and that energy travels between all the spheres.
Electromagnetic Spectrum (see diagram)
Convection is the transportation of heat energy from one place to another by the movement of a fluid.
Convection current is a current driven by differences in density.
Convection currents in the oceans are driven by differences in temperature and differences in salinity.
In the atmosphere warm air rises because gravity pulls the denser air down forcing the less dense air up.
Convection in the geosphere transports heat from deep in the Earth and the motion is a driving force for plate tectonics.
Conduction allows for the transfer of thermal energy between systems. The warm ground heats the air.
Energy in the form of solar radiation enters our planet systems and is converted and transferred back and forth. The energy is neither created or destroyed. Some energy is radiated back out into space. The rest is converted into chemical energy by photosynthesis or passed in some way around and around.

Notes for 3.1
The Earth has 5 primary spheres
Geosphere, Atmosphere, Hydrosphere, Biosphere, and Cryosphere (not in book)
Geosphere- Copy fig 2 on page 85, there are 2 ways of looking at the layers, by composition and by physical properties
Atmosphere- Bottom layer is the troposphere. We live in the troposphere and most of our weather takes place in the troposphere. The next layer is the stratosphere, then mesosphere, and thermosphere.
Convection is the transportation of heat from one place to another. The heat is carried by something (water, air).
Convection Current- A current driven by differences in density. Warm water is pushed up by denser cold water. The water carries the heat from one place to another.
Uneven heating of Earth's surface causes the movement of air. This movement transports heat from warm places to cold places keeping things moderate.
Hydrosphere- All of the water on the planet. 97% of the water is in the global ocean.
Biosphere- All the living and recently living things. Energy from the sun is converted to chemical energy by plants. That chemical energy and the matter in the organism is used by plants and animals (circle of life)

Habits of mind
4. Creative- Come up with new solutions, new ideas
5. Critical Thinking- The ability to analyze and make connections
6. Persistence- Do not give up, keep trying.
7.Adaptable- Adjust to the situation.
8. Integrity- Be truthful, honest.

Introduction Volume
Area unit is cm2
Volume unit is cm3
1 cm3 = 1 ml (milliliter)
1,000 ml = 1 Liter
Introduction Graduated Cylinder.
Hydrophobic- repels water.
Hydrophilic- attracts water.
Graduated cylinder is hydrophilic so the water climbs up the glass a little forming the meniscus.
Measure below the meniscus.
9/14
Volume by Displacement
Method for determining the volume of an irregularly shaped object.
- Measure the amount of water in the graduated cylinder.
- Add the object, make sure no air pockets are trapped in the object.
- Measure the water again.
- The difference between the two measurements is the volume of the object.
9/15
Introduction Triple Beam Balance
Before you measure an object follow these three steps.
- Clear the pan
- Set the weights to zero
- Check the pointer and adjust if needed
Fulcrum- The point that the beam balances on.

Introduction to the Caliper
(see post)
9/7
Caliper Lab
Question- What happens to the rate of change when I suck on a sucker?
Hypothesis- Do you think it will get smaller at a constant rate or does the rate increase or decrease and describe why.
Data Table vs Graphs
A data table (chart) organizes the data
A graph makes it easier to interpret the data.
- Pie Chart- good for showing the parts of a whole.
- Bar Graph- good at comparing.
- Line graph- good at showing change over time.
Create a data table from the Caliper lab trials.
(Bring data table to class 9/8)
9/8
Graph Caliper Lab Data and discuss results.
Line Graph
- Make sure you place a descriptive title at the top of the graph.
- Label the X and Y axes and include the units.
- Scale your graph so that the data range fits and fills the graph. (don't make a graph with all your data points in the corner and the rest of the graph is empty)
- If graphing multiple lines include a legend (key).

Introduction Habits of Mind
Curiosity- It is important for scientists to be curious. Curiosity drives them to figure out new things.
Open to New Ideas- Scientists need to keep an open mind and consider new ideas.
Skepticism- Scientists need to be critical and question those same ideas.
Here is an image of the calipers we will be using in class.
The zero on the moving jaws indicates the current setting.
This caliper is currently set to 22mm.
-"Mind the Gap" Measure with the parts of the jaws that touch when it is closed.
-3 measurements shown in the picture. The upper jaws (inside diameter), lower jaws (outside diameter), the stinger (measures depth)
