1. Unit 1- Scientific Method/ Graphing/ Life By: Bridget Jackson, TJ Scott, Roxana Beladi, and Emma Kersey

2. Scientific Method Scientific Method is series of steps that is used to conduct an experiment. The steps are: 1.Purpose 2.Research 3.Hypothesis 4.Experiment 5.Analysis 6.conclusion

3. Scientific Method Purpose: Why is the lab is being conducted? What is trying to be discovered? What is the intent of the lab? The purpose gets the lab started…with the problem Research: Provides background information based on the purpose. Hypothesis is based off of this research. Extensive research is vital for better understanding of the lab.

4. Scientific Method Hypothesis: Educated guess on what the outcome of the experiment will be… Based on knowledge that you know and on what you find from your research. Experiment: A series of actions that will prove the hypothesis correct or incorrect, and it must be controlled. The experiment contains an independent (the variable that is manipulated) and dependent variable (relies on independent variable).

5. Scientific Method Analysis: This is to state the outcome of the experiment briefly. A graph or chart, according to the data, has to be shown to prove the outcome of the experiment. Also, any calculations, or qualitative data is shown in this area of the experiment. Conclusion: This part of the experiment is to explain what happened, why, and what could be a possible future experiment. This also explains the independent and independent variables, as well as analyzing the data.

A- Constant; Unconstant B- Dependent; Independent C- Control; Uncontrol D- Qualitative; Quantitative

7. 4) The analysis ____________. A- States the purpose of the experiment. B- States the series of actions that will prove the hypothesis. C- Develops a procedure. D- The outcome of the experiment. - 5) The conclusion come ____________. A- Before the research section. B- After the analysis section. C- In between the hypothesis and analysis sections. D- Before the purpose section. 6) What is the difference between a scientific theory and a hypothesis? A- Nothing B- A scientific theory has already been proven C- A hypothesis has not been proven D- B and C

8. Life

9. Characteristic of Life All living things: Are made up of cells Are made up of cells Have the ability to adapt Have the ability to adapt Can reproduce Can reproduce Are based on a universal genetic code Are based on a universal genetic code Are able to maintain a stable internal environment Are able to maintain a stable internal environment Grow and develop Grow and develop Evolve Evolve Obtain and use material and energy Obtain and use material and energy

10. Branches of Biology

11. Individual- individual living thing Population- group of organisms of one type that live in the same area. Community- populations that live together in a defined area. Ecosystem- community and its surroundings. Biome- group of ecosystems that have the same climate and similar dominant communities. Biosphere- the part of Earth that contains all biomes.

12. Fun-Size Quiz 2 1) What isn’t a characteristic of life? A- Can adapt to its surroundings B- Breathes oxygen C- Reproduces D- Has cells 2) What is alive? A- Fire B- Tree bark C- Clouds D- Mirror 3) If something unknown is found, how can you tell if it is alive or not? A- Check to see if it is breathing B- See if it moves C- Gives off heat D- See if it has cells

13. 4) What isn’t alive? A- Flower B- Bacteria C- Table wood D- Cells 5) What is the broadest level of organiztion of life? A- Biosphere B- Ecosystem C- Community D- Population 6) What is an ecosystem? A- Organisms living together in an environment B- Group of the same organisms C- All life D- Population

14. 7) Which are characteristics that fire has similar to living things? A- Moving B- Can spread or grow C- gives off heat D- needs energy to live 8) Which is an organism? A- A group of seals B- Many of the same species C- One ant D- Many ants

15. Graphing We will cover terms including Independent variable Dependent variable Qualitative data Quantitative data Examples of appropriate graphing

16. Graphing Independent Variable Definition: a factor in an experiment that a scientist purposefully changes; also known as a manipulated variable. The independent variable is graphed on the y-axis. Dependent Variable Definition: A factor in an experiment that a scientist wants to observe, which may change in response to the independent variable: also known as the responding variable The dependent variable is graphed on the x-axis.

17. Graphing Qualitative Data Definition: Data that is descriptive and involves characteristics that can not usually be described with numbers. Examples of qualitative data include color, shape, and mental or physical states. Quantitative Data Definition: Data that is described by numbers, obtained by counting or measuring. Examples of quantitative data include percentages, ratios, measurements, and averages.

18. Graphing Types of graphs typically used in science: Bar graph Line graph Pie Graph Scatter plot graph This graph above is a line graph. This graph above is an example of a bar graph

19. Fun-Size Quiz 3 1) Which axis does the independent variable go on? A- x-axis B- y-axis B- c-axis C- z-axis 2) Which is an example of quantitative data? A- A yellow frog. B- A squid. C- 3 squids. D- A jelly bean. 3) Which is an example of qualitative data? A- A yellow frog. B- A squid. C- 3 squids. D- A jelly bean.

20. 4) Which is a bar graph? 5) Which is a line graph? A B C D

21. In the graph below what is the dependant variable? A- Number of individuals B- Year C- number of dolphins seen in Santa Barbra D- 1996-2001
