Metric System
Know how to convert one type of unit into another.

7. Name the four main types of basic metric units.

8. Meter - Length
Liter - Volume
Gram - Mass
Celsius - Temperature

9. Convert
25.6 cm = __?__ Km
K H D B D C M

10. 25.6 cm = _______ Km How did we get that? K H D B D C M 0.000256

11. What are the steps of the scientific method?
What is important about a hypothesis?

12. Observation Problem/Question Hypothesis Experiment Data Analysis
Scientists observe the world and want to know why things happen
Observation
Problem/Question
Scientists develop an “If, then” statement. Scientists must be able to TEST their hypothesis
Hypothesis
Scientists test their hypothesis and collect data
Experiment
Scientists look at their data
Data Analysis
Was the hypothesis supported or not supported?
Why or why not?
Conclusion
Report Findings
Scientists want others to know and they can also test the findings

13. What is a Zero Treatment Control?
What is a CONTROL group?
What is a Zero Treatment Control?
What is an Experimenter Selected Control?

14. What is a Zero Treatment Control?
What is a CONTROL group?
Used as a COMPARISON tool for your data. It does NOT get the IV.
(such as the plant that gets normal amt of light)
What is a Zero Treatment Control?
Control group gets NO treatment Ex: No jumping jacks and measure pulse vs. 100 jumping jacks and measure pulse
What is an Experimenter Selected Control?
The experimenter chooses the control. Ex: Regular dog food and dog growth vs. New improved dog food and dog growth

15. What are VARIABLES?

16. What are VARIABLES?
Things that are changed in an experiment

17. What is the INDEPENDENT VARIABLE?
Normal Sun 1 Hr of Sun 2 Hrs Sun 3 Hrs of Sun
Measuring plant height (growth) after 7 days.
What is the INDEPENDENT VARIABLE?

18. I.V. = Amount (Hrs) of Sun given to the plants
What “I” change in the experiment.

19. What is the DEPENDENT VARIABLE?
Normal Sun 1 Hr of Sun 2 Hrs Sun 3 Hrs of Sun
Measuring plant height (growth) after 7 days.
What is the DEPENDENT VARIABLE?

20. D.V. = The height of the plants after 7 days
The “D”ata collected.

21. What is the control in this plant experiment?

22. Plant that got
Normal Sun
Experimenter selected control

23. What could be some constants in this plant experiment?

24. CONSTANTS These items all stay the same from one plant to the next
Soil
Amount of water
Type of plant
Size of container
CONSTANTS
These items all stay the same from one plant to the next

25. What is DATA?

26. What is DATA?
Information collected from conducting an experiment.

27. What is QUANTITATIVE DATA?

28. Quantitative Data that is measured and numbers are obtained
Observations
Hint: Quantitative has an “N” for NUMBERS

29. What is QUALITATIVE DATA?

30. Qualitative Data obtained using 5 senses
Observations
Color, sound, taste, etc.

31. What is a THEORY?

32. What is a THEORY?
A well tested hypothesis that is supported by repeated testing.

33. What are the 8 Characteristics of Life?

34. What are the 8 Characteristics of Life?
Metabolize gain and use energy (food)
Made of at least 1 or more cells
DNA (Universal Genetic Code) Genetics
React to environment (Put on coat when cold)
Adapt/Evolve- Adjust to your environment (More fur in cold climates)
Homeostasis – Maintain stable internal environment
Grow and Develop (Baby to adult to old man)
Reproduce – must do this for species to survive

35. Name the levels of living things largest to smallest

36. Biosphere = All areas of earth with life
Ecosystem = Living and non-living in an area
Community = Different species in an area
Population = Same species (organisms) in an area
Organism = Group of organ systems make up this
Organ system = Group of organs working together
Organ = Group of tissues working together
Tissue = Group of cells working together
Cell = SMALLEST LIVING THING!!!
Molecule = Units that make up cells NOT LIVING

39. What is the main definition of a species?

40. What is the main definition of a species?
Must be able to reproduce and produce fertile offspring.

41. What is metabolism?

42. Process of gaining and using energy
What is metabolism?
Process of gaining and using energy

43. What is …

44. What is …
Keeping a stable internal environment such as temperature or pH.
