Bell Ringer1. Choose an Earth Science branch. List how

some of its studies relate to Earth’s spheres.

2. Explain how features in each of Earth’s spheres are changing over time.

3. Describe a situation in which two or more of Earth’s spheres are interacting.

* Refer to pages 1-10 to assist you in answering your questions.

What is Earth Science?Earth Science: the scientific study of our

planet, the Earth.

It encompasses all sciences which focus on the Earth, and uses physics, geology, geography, meteorology, mathematics, chemistry, and biology.

What is Earth Science?The Earth sciences generally recognize four

"spheres" of study of the Earth:

the lithosphere (land)The hydrosphere (water)The atmosphere (air)The biosphere (life)

Earth Science in our lives…

Morning, noon and night we encounter Earth Science!For example: I wake up in the morning and use a

bar of soap (minerals from the earth)

Take 10 minutes and create a timeline from—

morning----------------afternoon---------------night

Find at least 5 things in your life that involve earth science

EES in Daily TimelineMy example:

Morning:

I drive my car to school = burning gas, fossil fuels from earth

Afternoon:

On my way home, I drive on the paved road

Evening:

I need running water to brush my teeth before bed

•You have probably learned that the scientific method is the way scientists approach their work. •The scientific method: is a series of steps that help to investigate a question.

•Scientists use data and evidence gathered from observations, experience, or experiments to answer their questions

The Scientific Method

Hypothesis vs. Prediction

Predictions - statement made describing a possible explanation that will occur in the future

Ex: I think I’m going to get an A in Earth and Environmental Science this semester.

Hypothesis - testable statement that explains natural phenomena. It describes a cause and effect relationship (not just "educated guesses").

• ALWAYS in the “if, then” format

Ex: If I do all of my work and study, then I will get an A in Earth & Environmental Science this semester.

Hypothesis vs. Prediction

Prediction or Hypothesis?

What’s under the box?

Prediction or Hypothesis?

If I study longer, then I will get better grades.

Writing A Proper HypothesisUsing the “If / Then” Method

Writing your HypothesisIF (independent variable), THEN

(dependent variable) Independent Variable = waterDependent Variable = plant growth

Example: If I water the plant, then it will grow.

What Makes a Hypothesis Good?

Components of a good Hypothesis: It explains the problem It is testable (therefore it CANNOT be about

supernatural or mystic events) It is as simple as it can be, while still fulfilling the

first two items

Write your own hypothesisA dog owner wants to test how exercise affects

how his dog sleeps. The owner predicts that the dogs exercise will correlate with the number of ours he sleeps. He was careful to give his dog the same amount of food on the days he did the experiment.

Write a hypothesis for the dog owner.

Theory vs. Scientific LawScientific Theory – is a well-substantiated

explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation.

Scientific Law – A statement based on repeated experimental observations that describes some aspects of the universe.

Time to put those new hypotheses and predictions to the test…
