1. Name at least 1 specific example of each
type of mountain.

4. What is another name for the Great Plains?
This ball was once a glowing mass
Of mixed and superheated gas,
Till it cooled to liquid, shrank in girth,
Solidified and turned to earth.
For several thousand endless ages
It muddled through its early stages
Of heat, eruptions, floods, and quakes
And other infant bellyaches.
Surviving all such pains and notions,
It settled down as land and oceans.
In eras that are known as “glacials”
The planet then got several facialsWhich filled its unbecoming dimples
And leveled off some rocky pimples.
If, sometimes, there’s a recrudescence,
It’s due, no doubt, to adolescence,
But in the main, we are now able
To say the Earth is fairly stable
And, in most geologic features,
Better balanced than its creatures.
By Joseph S. Newman

 Study
for Chapter 1 Test!!!
In your notebooks, answer the following
question:
 What is the scientific method? If you are
not sure, take a guess!!!
Objective:
 List and describe steps used in the
scientific method.
The Scientific Method
How do scientists do what they do?
Well, YOU know because you’re a scientist too!
Observation is an important part –
in fact it’s the part at the very start.
For it’s observation that causes you to wonder why
earthworms do what they do and clouds form in the sky.
Your hypothesis is a “best guess” based on what you know
about how things work – now you’re ready to go!
Experimentation lets you test the hypothesis you’ve made –
to see if your best guess can make the grade.
And because variation is found in nature everywhere,
repeated trials should be done, and done with care.
And don’t forget to decide what variables you’ll test.
You change the independent variables, but not the rest.
Recording your data is very important, too;
so you can analyze the results and others can
repeat what you do.
When you’ve summarized your results
and your experiment is done,
You’ll have more information about nature
and you’ll have some fun.
So, now you know that the scientific method is really
cool,
and that scientists don’t just measure – they RULE!!!
Determine the problem
2. Make a hypothesis
Test your hypothesis or a prediction
that can be tested
4. Analyze your results
5. Draw conclusion
1.
3.
Science is my thing today.
When you do science – here’s the way:
First ask questions – why or how?
Then hypothesize – do it now!
Experimentation is next in line.
You get results that are SO fine!
Analyzing data comes up next.
Then graph your data, to show it best.
Being a scientist – it’s a trip!
It’s not square – it’s really hip!
1.
What are the five steps in the scientific
method?
2.
Define the term hypothesis.
3.
When completing a __________, using
the scientific method becomes helpful.
