A statement based on your experience is called an _______________.
Inference
It is the start of a new school year. Make an inference about when the school day will end. On what experience is this inference based?
Explain to me the difference between Mass and Weight.
Mass = how much matter you hold
Weight = how much matter you hold + gravity
Study the following picture. Which is the oldest layer of rock?
Which layer is the youngest?
A = oldest
E = Youngest
The energy of motion is called ___________
Kinetic energy
Define SCIENCE
Science is a process for answering questions. You start the science process by making observations.
Tell me the formula for area and volume
Length x Width = Area
Length x Width x Height = Volume
How much uranium is left if a solid piece goes through: a. one half-life? b. two half-lives?
a. 50% of the original amount
b. 25% of the original amount
__________is the transfer of heat through the motion of gases and liquids such as air and water. Explain to me how a lavalamp works.
convection!!
You observe that the plant in the window is turning brown. State a hypothesis to answer the question: Why is the plant in the window turning brown? Explain how you could test your hypothesis.
Hypothesis: The plant is turning brown because it has been given too much fertilizer. I could test this hypothesis by buying three of the same plants and change how much fertilizer each gets, giving one too much fertilizer, one too little, and one no fertilizer.
Tell me the difference between an independent variable and dependent variable
An independent variable is the variable that scientists change on purpose in an experiment. The dependent variable is the variable in an experiment that changes as a result of how another variable is changed.
Write a description that explains the wet and dry conditions for a tree with 25 rings.
25 rings = about 25 years old.
Wide tree rings indicated a very wet year and narrow rings indicated a dry year.
Relate the amount of kinetic energy to the speed of atoms.
faster the atoms, the more kinetic energy, the hotter the temperature.
slower the atoms, the less kinetic energy, the cooler the temperature.
What is the difference between an observation and an opinion?
An observation is a description of a thing or an event. An opinion is a statement that explains how you felt about some event or thing.
There are 3 graphs below. Identify each type of graph:

1- bar graph
2- pie graph
3- line graph
Tell me the order of the geological time eras and what lived in each period.
Cenozoic era = present. (Humans!)
Mesozoic era = Earth’s continents were connected in one “supercontinent” called Pangaea (Dinosaurs, flowering plants)
Paleozoic era = complex life forms developed, but glaciers covered the Earth in the Ordovician period, causing many of these new organisms to become extinct. Fish, reptiles, and amphibians developed during the rest of the Paleozoic era
Precambrian era = layers of rock formed the Grand Canyon and only single-celled organisms lived on Earth.
Conduction is the transfer of heat by the direct contact of atoms and molecules in solids. Give me an example of conduction.
ie. If you hold an ice cube in your hand, warmer hand atoms will transfer heat by conduction to the cooler ice cube atoms.
Explain to me the steps of the Scientific Method
Make observations, ask questions, state a hypothesis, collect data, draw conclusions
How many meters does each value represent?
a. 1,000 millimeters
b. 300 centimeters
c. 2 kilometers
a. 1 meter
b. 3 meters
c. 2000 meters
Compare and contrast bathymetric and topographic maps.
_________ is heat transfer through empty space. Heat transfer by radiation occurs without direct contact or movement of atoms.
Radiation is heat transfer through empty space. Heat transfer by radiation occurs without direct contact or movement of atoms.
