Thinking Like a Scientist
Name three of the seven steps of the scientific method.
What is ask a question, do background research, form a hypothesis, conduct an experiment, collect data, analyze and interpret data, draw conclusions, and report your findings?
Energy due to motion is _________ energy, while stored energy is __________ energy.
What is kinetic, potential?
The type of energy transformation that occurs when a rollercoaster goes from the top of the tallest hill to the bottom.
What is gravitational potential energy --> kinetic energy?
The definition of matter.
What is anything that has mass and takes up space?
An interaction between organisms in which one hunts down and feeds on the other.
What is predation?
The variable that is changed in an experiment.
What is an independent variable?
The two factors that affect potential energy.
What is mass and height?
The type of energy transformation occurs when you turn on the toaster.
What is electrical energy --> thermal energy?
The three subatomic particles that make up atoms along with their charges.
What is protons (+), neutrons (0), and electrons (-)?
How the amount of water affects the number of organisms in an ecosystem.
What is more water likely indicates more organisms while less water would result in less organisms living in the ecosystem?
The variable that is measured in the experiment.
What is a dependent variable?
The energy stored in batteries is an example of what specific type of potential energy?
What is chemical potential energy?
The type of energy transformation that occurs when you turn on the TV.
What is electric energy --> light (radiant) and sound energy
The number of atoms of each element and the total number of atoms in the compound Ba(SO4)3.
What is Ba=1, S=3, and 0=12 with a total=16?
How carrying capacity and limiting factors are related.
What is the amount of limiting factors in an ecosystem determines the carrying capacity?
Identify the independent and dependent variables from the following scenario:
Students measured the temperature at different depths in Lake Superior and found that the temperature varied.
What is the independent variable is the depth, while the dependent variable is the temperature of the water.
As you sled down a hill, how does the kinetic and potential energy of the system change?
What is potential energy decreases and kinetic energy increases?
Type of energy transformation occurs when you turn on a battery powered flashlight.
What is chemical potential energy --> light (radiant) energy?
Both H2O (water) and O3 (ozone) are molecules, but only water is a compound. Why is that?
What is ozone cannot be a compound because it consists of three atoms of the same element?
What is a lack of resources, high population density, increased competition, and an unhealthy environment?
The height of bean plants depends on the amount of water they receive.
Name two controlled variables for this scenario/experiment.
What is the amount of sunlight, the location of the plant, the type of soil used, the size of the pot, etc.
Look at the picture drawn on the board. At what point is the kinetic energy increasing?
What is point B?
In energy transformations, waste energy is always produced. What type of energy is waste energy?
What is thermal energy?
Give two examples of heterogeneous and homogeneous mixtures.
Answers will vary.
Many species cannot live at high altitudes due to the lack of oxygen and extreme cold. Is this an example of a density-dependent or density-independent factor that could affect a population?
What is density-indepedent?
