1.
What are the 7 characteristics of life and give an example of an animal, plant,
bacteria, or other living thing using these traits.
• All living things have cells/contain DNA
•
•
All living things respond to stimuli
•
•
Ex: dogs grow from a puppy to adult
All living things are able to reproduce
•
•
Ex: dogs eat dog food in order to get nutrients
All living things grow and develop
•
•
Ex: dog’s average temperature needs to stay between 100-102oF
All living things need metabolism
•
•
Ex: dog wagging tail or scratching ears
All living things maintain homeostasis
•
•
Ex: a dog has cells that can be viewed under a microscope
Ex: dogs can birth a litter of puppies
All living things evolve
•
Ex: dog’s show common ancestors with other animals
• What are the three domains of life?
• Archaea
• Bacteria
• Eukarya
• What does it mean if something is a theory?
• It is a highly tested experiment that the results can be replicated
by many scientists and is generally accepted in science.
• What are the steps to the scientific method?
• Observation  question  form a hypothesis  test with
experiment  data and analysis  conclusion  theory
• What is the organization from cells  organism?
•
Cells  Tissue  Organ  Organ system  Organism
• What is the definition of ecology?
•
The study of relationships and interactions of organisms in their ecosystem
and environment
• What is a hypothesis? What can it lead to?
•
A hypothesis is an educated guess that can be tested and be supported or
rejected. It can lead to a theory
• How can you tell if an experiment is controlled or not?
•
In order for an experiment to be controlled you need a control group and an
experimental group.
•
What type of graph/chart is best used to show percentages of a whole?
• Circle graph/Pie Chart
•
When should you use a bar graph?
• A bar graph is best used when comparing data with other numbers or categories.
•
When should you use a line graph?
• A line graph is best used when plotting data over a period of time.
•
•
Explain the differences between the independent and dependent variable.
• An independent variable is what is being tested.
• A dependent variable is the results or response to the experiment.
•
•
What are the three important parts of a graph that should always be included?
• Title you graph
• Label your axis
• Set your intervals or plot your data
• What is a control group? What is an experimental group?
• A control group is not changing in any variable, the results are
known, and are compared to the experimental group
• An experimental group changes in one variable and is compared
to the control group
• What is the difference between the independent and dependent
variables?
• The independent variable is what is being tested and how the
control group and experimental group differ.
• The dependent variable is the data from the experiment – the
output from the experiment
