Vocab
This is the term for a testable statement. This may also be called an educated guess.
Hypothesis
This is term is the first step of the scientific method.
Make an observation and ask a question.
These are the basic building blocks of all living things
Cells
In our lab, we are trying to understand the effects of pH on the growth and development of grass. Which group would be considered our control group (why is it the control group).
This is the term for the type of data that is measured using descriptive language, such as colors
Qualitative data
This is the term for the most well-supported explanation for a broad range of natural phenomena.
Theory
This term is the second step of the scientific method.
Create a hypothesis.
This process is the creation of new organisms from existing ones.
reproduction
In our lab, we are trying to understand the effects of pH on the growth and development of grass. Which variable would be the dependent variable?
The growth and development of the grass.
Name at least one of the goals of science.
To provide natural testable explanations of events in the natural world
To understand patterns in nature
To use data to make useful predictions and explanations about natural events
This is the term for the variable that is purposely changed or manipulated in an experiment.
Independent or Manipulated variable
This term is the third step of the scientific method.
Design and perform an experiment.
Despite external changes, organisms maintain a stable internal condition through this process.
Homeostasis
In our lab, we are trying to understand the effects of pH on the growth and development of grass. What would be considered the independent variable of the grass? How is it altered?
The pH of the soil. It is altered by manipulating the amount of salt (acid) and baking soda (base).
What must scientists do before they publish their research in a scientific journal?
Repeat the experiment and get the results peer-reviewed.
This is the term for the variable that is measured, or responds to change in an experiment.
Dependent or responding variable.
This is the term for the fourth step of the scientific method
Collect and analyze data
This is the scientific term for an organism's reaction to a change in its environment.
Response to stimuli
This is the term for the group in our lab that has had its variables manipulated.
Experimental group.
This genetic component is passed from parent to offspring during reproduction.
DNA
This is the term for the type of data that uses numerical information and measurable information to make informed decisions.
Quantitative data
This is the term for the fifth step of the scientific method.
Come to a conclusion, repeat experiment and communicate the results.
A tadpole becoming a frog or a seed sprouting into a tree are examples of this two-part process.
Growth and Development
This is the term for the type of data we will be collecting when measuring the amount that the grass has grown.
Quantitative data
Characteristics of Life: Over many generations, a species changes its heritable traits to better survive in its environment, a process known as this.
Evolution
