Earth Science

1
What is Science?

• Earth Science
• Mr. Gautschi
• Room E151

2
Agenda

• Objectives
• Thought Question
• Group Brainstorming Activity
• Note Taking Taking Notes
• Vocabulary
• Understanding Metric Conversion

3
By the end of the Lessons you should be able to

• Explain and define the different steps of the
  scientific method.
• Identify and use SI units used to measure mass,
  length and volume.
• Convert between metric units (e.g. kg
  g).
• Describe the different types of variables (I/D)
• Compare and contrast qualitative and quantitative
  observations
• Decide whether or not a statement is a hypothesis.

4
Thought Questions (read em, write em, do em)

• Define the following words using your own terms
• Science
• Technology
• Why do students take notes?

5
Cornell Notes

• Note taking is an art form. Notes should allow
  the student to find and acquire information
  quickly and easily.
• Cornell notes not only help to keep information
  organized but also allow students to reflect on
  the information being presented to them.

6
Vocabulary

• Scientific Method-the process that scientists use
  to solve problems and answer questions the
  following are the steps of the scientific method-
• Identify a Problem/Ask a Question- after you do
  this you want to gather as much info as possible
  to help create an informed hypothesis
• Form an Educated Hypothesis (must be testable)
• Design an Experiment (tests the hypothesis)
• Make Observations during experimentation
• Analyze/Display Data (tables, calculations
  graphs)
• Come to a Conclusion (Reject or accept
  hypothesis)
• Communicate Your Results (put info into your
  lab-book including colored diagrams)

7
Vocabulary (Continued)

• Hypothesis- A prediction that can be tested
• Control- The standard used to compare with the
  outcome of a test the base line
• Variable- The factor(s) that is/are tested in an
  experiment the part of the experiment that
  changes
• Theory- An explanation of things or events based
  on many observations (explains Why things
  occur)
• Law- A reliable description of nature based on
  many observations and vast amounts of scientific
  data (explains How things occur).

8
Observation Application

• Quantitative- a determined or estimated amount
  involving the measurement of an object
• The 500 kg lion has 6 cm long claws at the end of
  each of its 18 toes.

• Qualitative- an intelligible description or
  feature by which a thing may be identified
• The cute, fuzzy, tan colored lion has sharp teeth
  and a long tail.

Application- new use to which results are put or
new techniques developed
9
Two Types of Variables

• Dependent Variables- affected by the change in
  the independent variable. The new value of the
  dependent variable is caused by and depends on
  the value of the independent variable.

• Independent Variables- a variable that is
  manipulated by the experimenter

Example Does the height a ball is dropped change
the number of bounces it will make? The height is
the Independent Variable and the number of
bounces is the Dependent Variable
10
Vocabulary (Continued)

• SI-The International System of Units
• also known as the metric system.
• Mass grams
• Length meter
• Volume Litre
• Temperature Celsius or Kelvin
• The metric system is used because it is easy to
  convert data sets/units

11
The metric system is a base ten system

Checking for Understanding

• Which of the following are examples of a
  hypothesis?
• Einstein was the smartest scientist of his time.
• All dogs are blue.
• Ice melts faster when salt is poured on it.
• Which SI Unit would you use to measure the
  following?
• Your weight
• How far it is from your house to school
• The temperature outside
• How much water there is in a cup
