Presentation Transcript

  1. Objectives • Learn Lab Safety • Identify Lab Equipment • Write Lab Reports • Learn Graphing Techniques • Contrast Theory and Hypothesis • Review Metric System • Learn common characteristics of Life Living Things

  2. A. Graphing Techniques Types of Graphs: BAR GRAPH • Use for “chunking” or ________ data • Show trends and ____________ • Does NOT allow ____________comparisons Grouping Compare Sizes Cause and effect

  3. Use for displaying __________ Does NOT allow ________________ comparisons A. Graphing Techniques Types of Graphs: CIRCLE OR PIE GRAPH Percentages cause and effect

  4. A. Graphing Techniques Types of Graphs: LINE GRAPH (scatter plot) • Used most often in ________ • Independent/ • Dependent Variable Comparison _______________ Science Cause and effect

  5. A. Graphing Techniques TWO VARIABLES WITH DIFFERENT SCALES

  6. A. Graphing Techniques: Cause and Effect Just because you can graph two things does not mean one _________ the other Causes What can you say about this? Thing 2 Number of Murders Thing 1 Ice cream sales

  7. A. Graphing Techniques: Remember • X is across, Y is up high • Independent = manipulated (cause) • Dependent = responding (effect) • Label x and y axis, title the graph • When time is a variable, it always appears on the X-Axis (Time is the ultimate independent variable; time waits for no one!)

  8. B. Metric System meter liter gram u = K H D u d c m ing ector oesn’t sually rink hocolate ilk

  9. B. Metric System – Sample Problems 1000g = ________ Kg 0.043 m = ___________ cm 0.23 Dg =________ g 15.25 cL = ___________ KL 345 m = ________ Km 101.34 Km = __________ mm 32 Dg = ________ mg 1.5 DL = ____________ KL 3.43 Hm = _______ dm 0.476 mL = _________ cL

  10. C. Studying Life What distinguishes a living thing from a non-living thing? The study of living things is called _____________ Biology

  11. Amoeba

  12. Paramecium

  13. Venus Flytrap

  14. Sea horses and leafy dragons

  15. Cephalopods

  16. A. What is Life? There are 8 characteristics of living things. Living things: 1. are made of basic units called cells. 2. are based on a common genetic code. Generally: DNA 3. obtain and use materials and energy.

  17. A. What is Life? 4. grow and develop. 5. reproduce. 6. respond to their environment. 7. maintain a stable internal environment (homeostasis) 8. taken as a group, change over time (evolve)
