List the levels of organization in the human body from most simple to most complex
cell --> tissue --> organ --> organ system
100
Chemical and physical processes that break rock into small pieces is called _______________
Weathering
100
You leave a glass of water outside. The particles begin wo move faster and spread apart. This means taht the liquid water is turning into a ________ because it is undergoing the process of _______________.
Gas, Vaporization (The liquid water turns into a gas when the molecules move faster and spread apart, meaning that the water is vaporizing).

An airplane flies 30 miles in 3 minutes. What is its speed? (DON'T FORGET UNITS!!)
10 miles/minute (Speed = Distance / Time)
100
Which era do we currently live in?
Cenozoic Era (Remember - C stands for current!!)
200
Your body wants to stay at equilibrium. This is called _________________
Homeostasis
200
Acid in rainwater reacts with a rock, wearing a hole in it. This is called __________________ (Be specific!)
Chemical Weathering
200
When sodium (Na) and Chlorine (Cl) are combined, they form the new substance NaCl (table salt). What type of change occurred?
Chemical change (Remember, anytime a new substance is created you are dealing with a chemical change)
200
A ball has a mass of 1 kg and an initial velocity of 3 m/s. The ball is given an acceleration of 10 m/s^2 for 5 seconds. What is the net force on the ball? (DON'T FORGET UNITS!)
10 Newtons Force = Mass * Acceleration! Force = 1 kg * 10 m/s^2 = 10 Newtons This problem has a bunch of extra information that you do not need to solve the problem.
200
A kiwi (Ms. Bock's favorite fruit :) was placed on the back seat of a car. The car then accelerated towards a wall at 60 miles per hour (watch out!). What happens to the motion of the kiwi immediately after the car hit the barrier?
The kiwi moved forward at 60 miles per hour. (Remember, no force acted on the kiwi. According to Newton's first law, it will continue moving at the same speed until it hits the wall and is thus acted on by a new force).
300
This system supplies the blood with oxygen.
Respiratory System
300
_____________ removes rock particles and _______________ moves rock and sediment to new locations.
EROSION, DEPOSITION (Erosion removes rock particles and deposition moves rock and sediment to new locations)
300
Where is most of the mass located in an atom?
In the nucleus (Remember, protons and neutrons - which are much more massive than electrons - are found in the nucleus)
300
My cat Teddy is running 3 m/s to the North. I am describing Teddy's ________________.
Velocity (Velocity = Speed and Direction!!)
300
In each of the following examples, identify whether work is being done on the object. (A) You pick up your science textbook to turn it in to Ms. Bock (something you should all be doing) (B) You hold a 100 kg weight as you're waiting to pump some iron (C) You push on your bike that is stuck in the mud and refuses to move
(A) WORK - You are applying a force and moving the science textbook (B) NOT WORK - The weight is not moving (C) NOT WORK - The bike is not moving Remember - an object must be moving in order for work to be done!

This system provides structure and protection to your body.
Skeletal System

Name the four agents (or causes) of erosion.
Water, wind, ice and gravity
400
I have 0 mass and a charge of -1. Which subatomic particle am I AND where am I located?
I am an ELECTRON and I am located OUTSIDE OF THE NUCLEUS.

Your science book is sitting on a flat table. Why does it not move?
there is no net (overall) force acting on the book.
400
List the 4 time periods of Earth's history in order from youngest to oldest.
Cenozoic-> Mesozoic -> Paleozoic -> Precambrian Time (Remember, Cenozoic is youngest and Precambrian is oldest!)
500
This system breaks down food so your body can absorb nutrients.
Digestive System
500
As it flows over the land, a glacier picks up and moves weathered rock pieces. This is called ______________.
Erosion
500
All substances are classified as elements, compounds, or mixtures. Identify the correct classification for each of the substances below. 1. Table Salt - ?? 2. Dirt from the woods - ?? 3. Classroom air - ?? 4. Copper wire - ??
1. Table Salt - Compound 2. Dirt from the woods - Mixture 3. Classroom air - Mixture 4. Copper Wire - Element
500
Which of the following is FALSE? (a) Weight is a measure of the force of gravity (b) Mass and weight measure the same thing (c) Mass is a measure of the amount of matter in an object (d) A person's weight would be different on the moon
(b) Mass and weight measure the same thing NOT TRUE! Mass is a measure of the amount of matter in an object; weight is the measure of the force of gravity on an object.
