What is the science and study of life.
One characteristic of life is when an organism responds to this.
What is stimuli.
When a new organism is made and created, it is known as this.
What is reproduction.
In a scientific investigation, after the question is defined, the next step is most likely this.
What is to form a hypothesis.
Scientists can do this over and over again to a good experiment.
What is repeat it.
What life function is associated with an organism ingesting another organism? (It starts with an "n")
What is nutrition.
This is the substance needed for aerobic respiration, and when it is not present, anaerobic respiration occurs.
What is oxygen.
This is the basic unit of life that all organisms have. They can have one or many.
What is a cell
The first step to forming an experiment is this.
What is making observations and forming a question.
When doing an experiment, you want to keep a group that has no change occur to it to compare with the experimental group. This group is called...
What is the control group
When creating a graph, the x-axis represents the independent or dependent variable?
What is the independent variable?
The life function that is responsible for the coordination and control of all life activities in an organism is known as this. (Think of homeostasis)
What is regulation
What level of organization in the human body is made up of cells and makes up organs?
What is tissues.
True or false; When conducting an experiment, your data should support your hypothesis to make your experiment valid.
False; good experiments can disagree with the hypothesis once you collect and compare the data.
I am trying to find out if playing video games before bed makes it harder to sleep at night. So Mr. Murphy (I) plays video games for 15 mins before bed every night and measures how long he stays asleep. He does this for 1 week. He then reads or relaxes 15 mins before bed and measures how well he sleeps. He does this again for 1 week. He compares the results.
What is the independent variable in this experiment?
What is the video game playing before bed or not.
Would a living or non-living object have metabolic processes occuring?
What would be living.
Which term refers to the maintenance of a stable internal environment in an organism?
What is homeostasis
Over many years, when a species undergoes a gradual shift of traits and adaptations and changes, it is knows as this.
What is evolution.
The part of the experiment that includes reviewing the data and forming an idea or statement based on the data is this.
What is a conclusion.

What is the dependent variable in this experiment?
What is how well he sleeps.
What is genetics.
An organism that creates its own food through a process known as photosynthesis or chemosynthesis. (Plants are this type of organism)
What is an autotroph
Type of transport, or movement of molecules, from an area of low concentration to high concentration, This requires energy.
What is active transport.
A scientific study showed that the depth at which algae were found in a lake varied from day to day. On clear days, the algae were found as much as 6 meters below the surface of the water, but were found only 1 meter below the surface on cloudy days when there was less sunlight. Create a hypothesis that best explains these observations?
What is light intensity affects the growth of algae.
I am trying to find out if playing video games before bed makes it harder to sleep at night. So Mr. Murphy (I) plays video games for 15 mins before bed every night and measures how long he stays asleep. He does this for 1 week. He then reads or relaxes 15 mins before bed and measures how well he sleeps. He does this again for 1 week. He compares the results. He finds out that he sleeps on average 45 mins less a night after playing video games compared to when he does not.
What could be a conclusion to this experiment?
Potential answers:
- Video games make him sleep less
- Reading/relaxing might make him sleep more
- He might need to measure this more nights to conform his conclusion of videogames affecting his sleep.
