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 • Ex: a dog has cells that can be viewed under a microscope

•All living things respond to stimuli • Ex: dog wagging tail or scratching ears

•All living things maintain homeostasis • Ex: dog’s average temperature needs to stay between 100-102oF

•All living things need metabolism• Ex: dogs eat dog food in order to get nutrients

•All living things grow and develop• Ex: dogs grow from a puppy to adult

•All living things are able to reproduce• 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
