What do protons tell you about an atom and what charge do they have?
Protons tell you the atomic number (name) of an atom and they are positively charged.
100
How are steep slopes represented on a topographic map?
Contour lines are closely spaced.
100
How do you calculate the atomic mass?
Protons + Neutrons
100
What are unbalanced forces?
Forces acting on an object that are unequal
100
If you get something in your eye use this piece of equipment
Eyewash station
200
Where are protons and neutrons are located?
In the nucleus.
200
What is a contour line?
A line on a topographic map that connects points of the same elevation.
200
What are rows and columns called on the periodic table?
Rows are periods and columns are groups/familes
200
What is Newtons' First Law of Motion?
An object at rest stays at rest and an object in motion stays in motion unless acted on by an outside force.
200
If you break a piece of glass in lab what do you need to do?
Tell the teacher
300
Where are valence electrons located?
In the outer most energy level.
300
Name two crustal features formed by a convergent boundary
Trench, Volcano, Mountain
300
What determines an elements chemical properties?
The number of Valence Electrons
300
What is Newton's second law of motion? How would you calculate acceleration?
Force = Mass X Acceleration: The relationship between the force of an object depends on its mass and its acceleration. You calculate acceleration by dividing Force by mass Force / Mass
300
What lab equipment do you need to measure the mass of a rock? What units will it be measured in?
Triple Beam Balance measured in grams
400
What are products and where are they located?
Products are new substances formed from a chemical reaction located on the right side of the arrow (yields) symbol.
400
How is new crust formed?
At a Divergent Plate Boundary (where two plates are moving away from each other).
400
What is a coefficient and what does it tell you about a chemical formula?
A coefficient is the large number in front of a chemical formula and it tells you how many compounds/molecules you have.
400
When calculating net force: objects going in opposite directions would be __________________
Subtracted.
400
How do you read a graduated cylinder?
At the bottom of the meniscus.
500
What is the law of conservation of mass and how can you tell if a chemical equation is following it?
Matter is neither created or destroyed. To follow the law equations have to have the same number and type of atom on each side (be balanced)
500
Describe a Convergent Boundary
Where two plates move toward one another and collide.
500
List all five ways you know a chemical reaction has taken place.
Color change Gas Prodution (Bubbles) Light Production Temperature Change Precipitate Formation
500
When opposite forces are unequal they are called ___________ forces. They cause objects to ________________, __________________, or move in the direction of the _______________ force. In other words, they cause objects to _________________.
Unbalanced, speed up, slow down, stronger, accelerate
500
What is the purpose of a Hypothesis?
An educated guess that tries to explain an answer to a question
