Mrs. Einstein

List 5 safety rules in the laboratory.

3. Objectives 1. SWBAT review safety procedures.
2. SWBAT explain their preconception of biology and biological scientists.

4. Do Now-
What is biology?
What topics do you study in Biology? List at least 5 topics.

5. Biology Study of life or once living things
Study the structure of living things and how they interact with one another
Study of how living things function

6. Think – Pair - Share What is a biologist?
Where does this type of scientist do his or her work?
Draw one!

7. Biologists… Study the diversity of life Research diseases
Develop technologies
Improve agriculture
Preserve the environment

8. Do Now How is biology used in a supermarket?
List at least 3 different ways.

9. 1.3 Nature of Science (pg. 16- 21)
Science is a body of knowledge based on the study of nature.
Scientific inquiry is both a creative process and a process rooted in unbiased observations and experimentation.

10. What is Science? Which of the following are considered science?
Astrology
Ornithology
Marine Biology
Religion
Zoology
Pseudoscience-

11. THE CUBES! FIRST RULE: Do not touch the cubes!
Let’s brainstorm: What questions do you have about the cubes?

12. The cubes Cont. What is on the bottom of the cube?
What is evidence? What does the word mean?
Using data (observations), try to convince me and your classmates what is on the bottom of the cube. Provide evidence!

13. Pick up the cubes… Go ahead!
There is no way of knowing the absolute answer to a scientific question.
WHAT? MRS. EINSTEIN? ALL THAT FOR NOTHING….
Nature of Science

14. Scientific Investigations
Let’s list the steps we went through in our scientific investigation

15. Do Now
List the steps of the scientific method

16. OBJECTIVES SWBAT identify the steps of the scientific method
SWBAT define and identify independent and dependent variables
SWBAT define and identify control and experimental group

17. An example experiment…
Who likes to cook???
How do you cook spaghetti?

18. 1. Ask a Question Scientific inquiry begins with observation.
Science inquiry involves asking questions and processing information from a variety of reliable sources.

19. Short Demo on …..

20. Observation vs. Inference
Observation- direct way of gathering information in an organized way.
Inference- taking observations and making a logical conclusion

21. Do Now
Try to list the steps of the scientific method!

22. Let’s make some observations and inferences!
Finding Nemo

23. Do Now
Explain why a virus is NOT considered alive.

24. Objectives 1. SWBAT practice making observations.
2. SWBAT differentiate between observations and inferences
3. SWBAT identify and practice the steps of the scientific method.

25. 2. Form a Hypothesis
Hypothesis - a testable explanation of a situation.
Hypothesis that are supported through experiments and data are then accepted in the scientific community.

26. 3. Collect the Data
Biologist conducts an experiment, (a phenomenon in a controlled setting to test a hypothesis).

27. 4. Controlled Experiments
1. Experimental Group- group that is being manipulated
2. Control Group- group you keep the same (all variables are constant)

28. 5. Experimental Design
Independent variable—only one factor in a experiment that can change
Dependent variable—results from or depends on changes to the independent variable

29. Think – Pair - Share
Identify : control group, experimental group, independent variable, dependent variable, constants
Food Scientists are working together to develop a better tasting sweet mint Trident gum. Each person sampling the gum gets ONE original sweet mint and ONE sweet mint with added spearmint to try to improve taste. The tasters did not know what they were trying and had to record their results.

30. 6. Data Gathering Data - information gained from observations.
Quantitative data - measurements of time, temperature, length, or other factors.
Qualitative data - descriptions of what our senses detect.

31. Data
I want you gather qualitative and quantitative data from this picture.

32. 7. Analyze the Data
A graph of the data makes easier to interpret.

33. Graphing
Analyze this graph.
Reach a conclusion!

34. 8. Report Conclusions
Conclusions are published so other can review the results and discuss the merit of the experiment.

35. 1 1 2 3 4 5 6

36. Do Now:
A new medicine is out on the market that helps people retain information better (smart pill). In a recent study, one group was given the smart pill and the other group was given a placebo (sugar pill).
Identify: 3 constants, control group, and experimental group
Explain why researchers found the need to have two different groups

37. Do Now:
A new medicine is out on the market that helps people retain information better (smart pill). In a recent study, one group was given the smart pill and the other group was given a placebo (sugar pill) both groups were graded on a math test.
Identify:
Control Group:
Experimental Group:
Independent Variable:
Dependent Variable:

38. DO NOW-Identify the following terms: identify the problem, hypothesis, experiment, independent variable, dependent variable, and create a conclusion
The leaves on my tomato plants were turning yellow. I was not sure what to do. I decided that maybe they were not getting enough sun. I moved one plant into the sun and left the other one where it was. I recorded the different shades of the leaves (yellow, yellow-green, and green).

39. Objectives
1. SWBAT identify and practice the steps of the scientific method.
2. SWBAT work in groups to identify control group, experimental group, hypothesis, conclusion, independent, and dependent variables.
3. SWBAT analyze a graph.
