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
