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 to move faster and spread apart. This means that 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).
100
An airplane flies 30 miles in 3 minutes. What is its speed? (DON'T FORGET UNITS!!)
10 miles/minute (Speed = Distance / Time)
100
What is a petrified fossil?
A fossil in which minerals replace all or part of an organism.
200
Your body stays the same on the inside even when your environment changes on the outside. 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 2 kg and a velocity of 3 m/s. What is the kinetic energy of the baseball? (DON'T FORGET UNITS!)
Kinetic Energy = 1/2 x mass x velocity^2 Kinetic Energy = 1/2 x 2 x 3^2 Kinetic Energy = 9 Joules
200
A kiwi (Ms. Bock's favorite fruit :) is flying through the air. It has a mass of 3 kg and a velocity of 4 m/s2. What is the kinetic energy of the kiwi? Don't forget units!
Kinetic Energy = 1/2 x mass x velocity^2 Kinetic Energy = 1/2 x 3 x 4^2 Kinetic Energy = 1/2 x 3 x 16 Kinetic Energy = 24 Joules
300
This system transports oxygen to the blood.
Circulatory 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
Which body system removes wastes from your body?
The excretory system
400
This system provides structure and protection to your body.
Skeletal System
400
Name 3 types of chemical weathering.
Possible options: water, oxygen, carbon dioxide, living organisms, acid rain.
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.
400
Your science book is sitting on a 4-meter table. Your book weighs 10 pounds. What is the potential energy of the book? (Don't forget to return your textbooks by tomorrow!!!)
Potential Energy = weight x height Potential Energy = 10 x 4 Potential Energy = 40 Joules
400
A scientist who studies fossils is called a _____________.
Paleontologist
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
What happens to the particles in water as water freezes?
The particles slow down and move closer together.
500
Which of the following is FALSE? (a) Kinetic Energy is the energy of motion (b) Potential Energy is the energy of position (c) Total Mechanical Energy changes as your kinetic energy changes (d) Velocity is speed with direction
(c) Total Mechanical Energy changes as your kinetic energy changes NOT TRUE! Total Mechanical Energy remains the same! It does not change!!
500
