What is Science?

Science is a process we use to answer questions about what we OBSERVE.

OBSERVATIONS

When you observe you become aware of something by using your senses: smell, sight, sound, touch and taste.An observation is a statement describing a fact.

OBSERVATIONS

When you observe you become aware of something by using your senses: smell, sight, sound, touch and taste.An observation is a statement describing a fact.

On your own paper, record 5 observations about this classroom.

Qualitative vs. Quantitative

• Observations can be qualitative or quantitative.

• Qualitative observations cannot be measured.Examples: red, hot, beeping noise

• Quantitative observations can be measured. Examples: 72 degrees, 18 centimeters, 45 mph

Quantitative or Qualitative?

• The room is cold.

Quantitative

Record 2 qualitative and 2 quantitative observations on your paper.

Record 4 observations. Label each qualitative or quantitative.

But I can’t see (hear,smell,touch or taste) it! What do I do?

There are some things that cannot be observed.

Details of Planets and Stars

Can you think of some ways scientists have solved this

problem?

Scientists often use inferences.

Inferences cannot be directly observed.

They require thought!!

When you infer you make educated guesses and judgements based on your observations.

An inference is a statement based on your interpretation of the facts.

Based on your previous observations, what do you think happened here?

And here?

Observation vs. InferenceObservation Inference

There is a car on the side of the road.

The plant is drooping and the soil is dry. The room smells and all the students are covering their faces.

The car is on the side of the road because it ran out of gas.

The teacher forgot to water the plant.

Someone ate tacos for lunch.

Look at these two sets of animal tracks.

Let’s Practice!

What can you infer about these people?

What is he thinking?

Why isn’t she using a fork?

Where are they? Do they know each other?

What happened here?

What do you think he is going to say?

What can you infer?

How does she feel?

What happened?
