16. Scientific method What is the scientific method?
The scientific method is a method that is used to find answers to questions about the world around us.

17. Scientific method Is there only one scientific method?
Some versions have more steps, while others may have only a few. However, they all begin with the identification of a question or problem to be answered based on observation of the world around us. The scientific method provides an organized method for conduction and analyzing an experiment.

18. Parts of sci. method Part #1: Ask the Question (Problem)
Scientific questions are testable, which means:
They cannot be a yes or no question.
You must be able to run an experiment to test the question.

19. Parts of sci. method Part #2: Gather Information (Research)
You should ask yourself: What do I know already? What do I not know?
Gather information about the problem before you experiment.

20. Parts of sci. method Part #3: Form a Hypothesis (Prediction)
A hypothesis is a prediction about the outcome of an experiment.
A hypothesis is usually an “if-then” statement.
A hypothesis must be testable through an experiment.
If I do this, then this will happen
Example: If I chew 1 piece of big red and 1 piece of 5 gum and record the average size of bubble each produces after 3 trials, then 5 gum will produce the biggest bubble.

21. Parts of sci. method Part #3 continued: Form a Hypothesis
Dependent vs. independent variable
1. Dependent variable: (“the effect variable”)
It is what is being studied
it is what you measure and what is being affected (the effect).
2. Independent variable: (“the cause variable”)
It is what you are changing in the experiment
It is what is affecting the dependent variable

22. Parts of sci. method Part #4: Test the Hypothesis (Experiment)
An experiment is a clear step-by-step procedure used to test a hypothesis.
There are 3 Main Parts of an Experiment
Materials = List the quantity and names of supplies and equipment used for the experiment
Procedure = step-by-step process on how experiment was performed
Results = You must clearly and accurately record the data you collect.
Remember, more data you collect, the more reliable your results. REPETITION is key!!!!

23. Parts of sci. method Qualitative Observation (QL)= descriptions
Part #5: Make Observations (Record Data)
Observations are things that you can see, hear, taste, smell and touch (the 5 senses).
Qualitative Observation (QL)= descriptions
Quantitative Observations (QN) = measurable things

24. Parts of sci. method You can analyze your results by doing:
Part #6: Analyze the Results (Analysis)
You can analyze your results by doing:
Calculations
Percentages
Averages
Tables
Graphs - bar, line, piece

25. Parts of sci. method Part #7: Draw Conclusions (Discussion)
It is a statement that sums up what you have learned from an experiment.
In this section include these 5 things:
Restate the lab’s problem
Summarize your results
State if your hypothesis was correct, incorrect, or inconclusive.
Suggestions to improve experiment
Explain how information gained in lab can be applied to real-life situations and how does it relate to major scientific principles, classnotes, or text

26. Parts of sci. method Summarize all the parts of your experiment
Part #8: Communicate Results (Publication)
Summarize all the parts of your experiment
You can create different types of write-ups:
Lab worksheet
Lab report
Science journal
Science Poster

27. Parts of sci. method Part #8: Communicate Results (Publication)
This summary should include the following things:
Introduction/Background Research
Problem
Hypothesis
Materials
Procedure
Observations
Discussion (Analysis of results)
Conclusion
References

28. Scientist observed that white mice that were fed seeds appeared to grow more than mice given vegetables. The scientists hypothesized that the protein in the seeds was responsible for the growth. They designed an experiment to test this hypothesis. They divided 200 mice of the same age, size, health, and sex into two groups of 100 mice each. The mice were kept under identical conditions for 14 days. One group was given a diet low in protein. The other group was given a normal protein diet. The mass of each mouse was recorded daily for 14 days.
 1. What conditions were kept constant in both groups of mice? 
2. What was the independent variable? 
3. What was the dependent variable?
4. What was the problem that the scientists were investigating?

Mr. Brown, who lived with his wife, kept their apartment very clean. He waxed the floors every day and vacuumed all carpet. He also dusted all furniture. One day, he discovered bites on his arm. He does not understand where they came from since he does not have bugs in his house. Where did the bites come from?

34. Environmental Science Classwork
Read/re-read pages 12 – 20. Answer the Lesson 2 Assessment on page 20.

35. During Classwork Time Stay focused on the assignments you are given.
Do the questions INDEPENDENTLY (on your own).
Keep the noise level down.
Ask THREE before you ask ME.
You may put earphones on and listen to music quietly as you do your work.
You must finish a certain number of questions (depends on the person) by the end of the period.

36. Quiz Expectations
Absolutely no phones, iPads, or any other electronic devices.
No talking or noise-making
No making signs
Only look at your paper
If you have a clarifying question, SILENTLY raise your hand. DO NOT ASK ME FOR ANY HINTS.
Stay seated at ALL TIMES. If you need something, RAISE YOUR HAND.
Failure to follow any of the above will lead to your exam being voided.
DO YOUR BEST! You got this.
