1. What are some types of scientific investigations?

2. A process for science
Scientists always start with a question to investigate.
A good question is one that can be answered through investigation
After a question comes an investigation
Scientific Methods are the ways scientists investigate the world
The methods used change depending on what question you are answering
Experiments are investigations that are controlled by the scientist
At the end of the investigation a scientist draws their conclusion.
The conclusion may answer the question asked or might create new questions.

4. Explosive Observations
Some questions can only be answered through observation
Some things are too big or dangerous to experiment with
Repeated observations are used to answer questions
Repeated observations of things (such as geysers) allow scientists to make predictions of natural occurences.
Predictions are about future events
Even questions about animals may be answered through repeat observations.

5. Super Models
When you cannot observe something in real life, scientists will build a model.
Conclusions can be drawn from observing the model
Scientists constantly update models as they learn new things
Types of Models
Physical- Actual built model that can be manipulated
Computer Simulations- simulate real events
Drawing a diagram- connects ideas
What would be the best type of model to study an ant hill? Why?

6. How to excel in experimentation
An experiment is designed to answer a question
Even before you make a hypothesis about your question, investigate your topic a little to learn more about it
Hypothesis: What you think the results will be of your experiment.
Use your research to create the best hypothesis
Design your experiment
It needs to answer your question
Pick a variable to test
A variable is the thing that changes with each experiment
Warning- There are many variables in an experiment, you must keep all variables the same except the one you are testing.
Among your tests must be a control (the

7. What is a Control!?
Control is the portion that you are not performing experiments on. It is just there to serve as the blank state that experiments compare to. For instance, in a drug trial, the control group are giving placebos and data from the experimental group that actually took the drug will be compared to it to see effects

8. Identify:
You are performing an experiment where you freeze different substances with water in them. You want to see which will freeze the quickest. In the freezer you place 10 oz of orange juice in a plastic cup, 10 oz of milk in a plastic cup, 10 oz of apple juice in a plastic cup, 10 oz of water in a plastic cup, and 10 oz of alcohol in a plastic cup.
What is the variable you are testing? What are some of the other variables that you are controlling? What is your control test?

9. How to excel in experimentation
Carry out your procedure
Each time you repeat your procedure is called a trial
If you are not getting a consistent result, keep trying the experiment and see if you made a mistake
Always repeat your procedure several times to avoid mistakes
Record your data
Determine which charts or graphs best represent your data
Determine what visuals to use (pictures are always good)
Draw a conclusion from your data
It must be supported with evidence from your experiment
Determine if your hypothesis was correct
If it was not rethink your hypothesis and fix the experiment to test it again.
