4. Inductive reasoning is basically an educated guess. Scientists use experience and knowledge to figure out and explain scientific results or questions.
5. A control group has no independent variable, but an experimental group, or groups, does/do. This means that you change something in the experimental group to see how it affects the dependent variable, but in a control you change nothing.

4.There are 2 broad types of reasoning: Deductive and Inductive.
Deductive is top/down thinking from general to specific
Inductive is bottom/up thinking from specific to general.
Observe—Find the pattern—Test your hypothesis—Form your theory.
5. Control group is held constant and variables do not change. Unknown to group they are given the placebo (sugar pill) and nothing should happen to them.
They should not get well.
Experimental group is giving the changing variables to see what happens. This groups is given the new antibiotic pill to see and observe if they get well.
1. body tube, revoling nose piece, objectives, diapharms, light source, ocular lens, arm, stage, coarse adjustment nobe, fine adjustment knob, base.
2. light- enlarge images up tp 1000 times their normal size. ocular is multipled by the magnification of the objectives lens being used.
electrons- transmits electron beams through a thin slice of a specimen to produce an image, speciman othen coated with golden atoms.
3. 1.Make an observation—using the five senses
2.Asking Questions
3.Form a hypothesis-an educational guess – “If then”
4. reasoning from detailed facts to general principles
5. Contol group is th group that is not really being tested and te experimental group is have data and test run to see the product really being tested is good or bad
1. body tube, revolving nose peice. low power objective, medium, high, stage clips, diaphragm, aluminator, eyepiece, arm, stage, course adj knob, fine adj knob.
2.an electron microscope uses beams of electrons and a light microscope uses beams of light.
3.ask a question, do the research, make a hypothesis, do the expirment, record charts and data,write a conclusion.
4.inductive reasoning is when u reasons with a specific case and bring up a general rule
5.the control group is what stays the same and the experimental group is is what is tested.
1.Eye piece revolving nose piece low power objective medium power objective and high power objective stage clips diaphram arm stage light source base
2.A light microscope uses a light source but a electron microscope has beams of electrons focused by magnetic lenses.
3.Ask a Question Do Background Research Construct a Hypothesis Test Your Hypothesis by Doing an Experiment Analyze Your Data and Draw a Conclusion
Communicate Your Results
4.reasoning from detailed facts to general principles
5.controled group is what ever being tested and the experimental group is what is being tested
1. List the parts of the microscope.
Body-piece, revolving nosepiece, low power objective, medium power objective, high power objective,stage clips diaphragm, light source, eyepiece, arm, stage, course adjustment, fine adjustment, base
2. What is the difference between a light microscope and an electron scanning microscope?
A light microscope enlargers an object and focuses in on it with two lenses and magnifying power while a electron microscope works to produce a 3-D view of the object.
3.List the steps, in order, of the scientific method.
make an observation, ask a question, for a hypothesis,set up an experiment and test it, collect data, form a conclusion.
4. Explain the meaning of “inductive reasoning”?
The ability a scientist has to draw information from knowledge and experience to make an explanation.
5. What is the difference between a control group and an experimental group?
The control group is a constant or something that has stayed the same or been used before. The experimental group is the new way or new product being used.
