1. Science Skills

2. Scientific Method
An organized plan for gathering, organizing & communicating information
Used for problem solving or to explain an observation

9. Scientific Method Vocabulary
Observation – obtaining information through 5 senses (qualitative/quantitative)
Hypothesis – a proposed answer to a question
If …. then because . . .
Variable – any factor in an experiment that can be changed

10. Controlled Experiment
An experiment in which one variable (IV) is deliberately changed, all other variables are kept constant
Independent Variable (IV) – causes change in another variable (what I change)
Dependent Variable (DV) – changes in response to IV (what you measure/your data)
Control Group (C) – does not get manipulated
Experimental Group(s) – gets manipulated
Controlled Variables (CV) – all variables kept constant in an experiment

11. Time to practice
Hypothesis worksheet
IV/DV worksheet

12. SI – International System of Units
aka Metric system
Length – straight-line distance between two points (meter – m)
Mass – quantity of matter in an object (gram – g)
Volume – amount of space an object occupies
(l x w x h = m3 (cubic meters))
Density – ratio of mass : volume (kg/m3)
Temperature – measure of thermal energy Kelvin (K)—Celsius (C)

14. Metric Mania
Lets put your skills into practice….

15. Data Table Put the following information into a data table.
Mrs. Walston wanted to figure out which type of dog had a faster average while running the mile – A pit-bull or a golden retriever.
The pit-bull had the following time – 10min, 8.5 min, and 9 min.
The Golden Retriever ran 9.5 min, 8.0 min, and 9 min.

16. Practice
Let’s make sure you have it!

17. Scientific Data and Analysis
GRAPHING:
Scientific Data and Analysis

18. GRAPHING: Line & Bar Graphs
Have an x-axis (horizontal) and a y-axis (vertical)
Each axis is a scale ranging from lowest number (data value) to highest

19. GRAPHING All Line and Bar Graphs Need: Title that describes graph
Labeled and Numbered X and Y Axes

20. GRAPHING
Bar Graphs
Compare measurements, amounts, changes

21. GRAPHING: Group Bar Graph
Also compares groups of data
NEEDS A KEY

22. GRAPHING
Line Graphs
Show a relationship between TWO factors– excellent for showing changes, trends, patterns over time/depth.
Allow you to graph more than one set of data on a single graph
MOST IMPORTANT: allow you to answer “IF/THEN” questions

23. Figure 21: Mass vs. Volume of Water – DIRECTLY PROPORTIONAL, as one value increase, the other value increases.
The slope tells the relationship between the variables.

24. Figure 21: Distance vs. Light Intensity – INVERSELY PROPORTIONAL, as the x-value increase, the y-value decreases.

25. GRAPHING: Multiple Line Graph
Compares different sets of data
NEEDS A KEY

26. WHAT IS WRONG WITH THESE GRAPHS?!
GRAPHING
WHAT IS WRONG WITH THESE GRAPHS?!

27. THE X AND Y AXES ARE NOT LABELLED!!!!

28. What makes a great title?
NO TITLE!!!!!!!
What makes a great title?

29. Y AXIS IS NOT NUMBERED

30. X AXIS HAS NO VALUES!!!!
