II. Problem Solving Steps:
A. The order of steps:
1. Identify the problem
- Write out the problem your trying to solve, or the question
to be answered in a clear and specific manner.
2. Collect information
- Information can be obtained from books, magazines, the internet, television, or people.
a. A credible source:
- a source that is backed by a respected organization and known to be true.
3. Form a hypothesis:
- Write out an educated guess as to what you think the results to the experiment will be.
4. Test your hypothesis:
- Develop and test your hypothesis with a properly structured experiment.
5. Form a conclusion
- Accept your hypothesis to true, or reject it and explain what you have found.
- If you accept it as true you must repeat it many times to prove it.
6. Report your results
- Report what you have found to others so they may learn from your experiment.
III. The Experiment:
A. The subjects in the experiment:
1. Control Subject:
- The subject in the experiment that remains unchanged from its natural form.
(elephant + water = control subject)
2. Experimental Subject:
- The subject in the experiment that has had something done to it that is
different than normal.
(elephant + pepsi = experimental subject A)
(elephant + coffee= experimental subject B)
B. Variables:
1. Controlled Variables:
- all of the conditions and differences that can occur between the subjects.
(amount of sun, water, food, temperature, age...)
2. Independent Variable:
- What the experimenter changes or does different to the experimental
subjects.
- There should only be one independent variable.
(What you give the elephant to drink.)
3. Dependent Variable:
- What happens as a result of the independent variable. What your are measuring.
(The elephant that drank the pepsi slept 3 hours less than the control.)
(The elephant that drank the coffee had explosibe diarrea all night and the
control subject did not)
C. Safety in the science lab.
1. The most important rule is to always tell the teacher if anything happens.
IV. Collecting Data
A. Recording your results
1. Observations:
-Dependent variables that you observe using your 5 senses.
2. Inferences:
- Ideas or conclusions that you come up with based on reasoning.
B. Data Table:
1. you first start by filling out the subjects.
2. Next you label the columns.
3. Fill in the data you receive. Add a total column if needed.
C. Graphing Data received:
1. Bar Graph:
- Always used to show a comparison between 2 or more subjects.
a. Steps to make a bar graph:
1. make a title.
2. Title the X & Y axis
3. Label the x and y axis
4. Create a key
5. Fill in the data from the table.
2. Line Graph
- Always used to show results that are taken over a certain time period.
a. Steps to make a line graph:
1. Title and axis titles.
2. label x and y axis. (Time is on the x axis.)
3. Create your key.
4. Plot the points on the graph.
5. Connect the dots.
D. Forming a conclusion:
1. Was your hypothesis correct.
2. What do you observe.
3. What can you infer.
4. What could you have done difr
