Chapter One Biology Review
• Name the steps of a scientific experiment.
• Dr. Herc• D= Define problem• r.= research• H.= Hypothesis• e.= experimental setup• r.= results• c.= conclusion
• Why should the problem be worded as a question?
• You are setting out to solve a question that you are curious about.
• Why is important to be curious in science?
• Curiosity leads to asking questions.
• What is inference?
• The ability to figure problems out before you start because you already have a world of experience in your life up until now.
• Is observation accurate? Why?
• No many people see and perceive differently.
• What is research?
• Collecting information about the topic of the experiment from other valid sources before you start an experiment.
• Why is it important to have a repeatable experiment?
• If the same conclusion is obtained then it becomes a scientific fact.
• What is a theory?
• Something that has probably occurred because there is a large body of evidence that shows is probably did.
• Explain what the two types of variables are.
• Independent is what is being manipulated.• Dependent is what occurs because of the
independent variable.
• What is the difference between qualitative and quantitative data?
• Qualitative is gathered through observation and quantitative is numerical.
• Qualitative can be recorded as a chart.• Quantitative can be recorded as a graph.
• What is the correct way to record a conclusion?
• State WHY you got the results that you did.
• What are the characteristics of living things?
• 1. Cells• 2. Reproduction• 3. Use energy• 4. Adapt• 5. Grow and develop• 6. Evolve
• Do all cells have DNA?
• yes
• Define growth.
• The increase of mass in an organism.
• What are the two types of reproduction?
• Sexual and asexual• Sexual requires gametes that fuse to form a
zygote.• Asexual spits and divides into two new cells.
• Why is reproduction in an organism important?
• It reassures the generation of species.
• What is the difference between a stimulus and a response?
• A stimulus is what affects an organism and response is the result.
• Give an example of an organism that develops.
• A mealworm turns into a beetle=metamorphosis.
• What are the four things we will be measuring in the science lab?
• Length• Mass• Volume • Temperature
• What is the basic unit of measure of length?
• meter
• What is the basic unit of measure of volume?
• Liter
• What is the basic unit of measure of mass?
• Kilogram or gram
• What is the basic unit of measure of temperature?
• Celsius
• How many centimeters are there in the meter stick?
• 100
• How many millimeters are there in the meter stick?
• 1,000
• How many meters does it take to measure a kilometer?
• 1,000
