Is She a Witch?
Any factor that can be controlled, changed, or measured in an experiment.
What is a variable?
This graph shows information that is connected in some way (such as change over time).
What is a line graph?
Energy formed when an atom splits apart or when two atoms join to form one.
What is nuclear energy?
A force (a push or pull) applied to an object which forces the object to move.
What is work?
An electric charge in motion. (electrons in motion usually in a wire)
What is an electric current?
This is the term we use to describe the manipulated variable or factor that the experimenter intentionally changes.
What is the independent variable?
This chart is best to use when you are trying to compare parts of a whole. It does not show changes over time.
What is a pie chart?
A nuclear reaction that invlolves the splitting of a heavy nucleus into a lighter nucleus.
What is nuclear fission?
Arkansas Tech University
What is OBU football's latest foe?
These are the negative particles found in atoms.
What are electrons?
An educated guess or prediction for what might happen in an experiment.
What is a hypothesis?
The independent variable is located on this axis.
What is the x axis?
Thorium-234 has a half-life of 24 days. If there was 100 g of Thorium-234 to begin with, how much is left after 48 days?
What is 25 grams?
This is an example of electrical energy being changed to radiant energy.
What is a lamp or a light bulb that is turned "on"?
The energy produced when a coiled wire is spun around a magnet.
What is electrical energy?
Read the following experiment and state a good hypothesis. I am doing a test to see if there is a connection between how long you run and how fast your heart beats. I will be performing an experiment where a person will run for a 1 minute and I will check their heartbeat. Then they will run for 2 minutes and I will check their heart rate. I will do this up to 6 minutes and see if there is a connection.
What is...If I increase the amount of time I run, then my heartbeat will increase.
The dependent variable is located on this axis.
What is the y axis?
In this type of reaction, two smaller nuclei combine to form a larger nucleus, releasing tremendous amounts of energy. It's also the type of reaction that occurs in stars.
What is fusion?
October 2 - October 5
What is Tiger Tunes/Homecoming?

What is the number of class days have we had (MWF classes) this semester?
Find the independent and dependent variables in the following experiment: If you increase the number of times you practice shooting free-throws, then you will increase your chances of making a basket every time.
What is Independent- practice shooting free throws, Dependent- making baskets.
This graph displays data either horizontally or vertically and allows viewers to compare items displayed.
What is a bar graph?
In this process, energy in the form of heat from the release of splitting uranium atoms turns water in a primary loop into steam. This steam goes on to heat a secondary loop of water. This heated water converts to steam which moves a turbine to generate electrical energy.
How a nuclear power plants work?
The energy conversion occurring when a candle is burning.
What is chemical energy transforming into radiant energy (thermal/heat + light).
Biomass, hydropower, geothermal, wind and solar are all examples of this.
What are renewable energy resources?
