Do Now: Write a detailed account of

what happened in the cartoon.

Tracking Our Mastery

We will be tracking how much we learn

throughout the year, so we can create goals.

1. Complete the mastery worksheet for the inquiry pretest

2. Update the mastery tracker in your notebooks for

Inquiry/Lab Safety/ and Procedures

3. Room should sound like a NINJA

Divide the number correct, by the total number of

questions for each category to find the percentage.

Observation vs. Inference

What is an Observation?1)

Qualitative observation:

Example:

Quantitative observation:

Example:

Make an observation about the

classroom.

Scientific Method

Scientific Method:

Observation

Qualitative: Descriptive – color, texture,

odor

Ex: My phone is running slower than my

friend’s phone

Quantitative: Numerical – 3.5 m, 65.7mL

Ex: My phone has 50 more apps than

my friend’s phone

Observations

The plant is green.

The piece of metal is orange.

It is raining outside.

The car alarm is beeping 5 times

per minute.

The wall has a 2m crack in it.

The room feels humid.

Observations & Inferences

Turn and talk with your partner

Make at least 5 observations

about the picture below

Inference

A conclusion drawn using observations and

reasoning

NOT a fact you can detect using one of the

five senses

An explanation of your observation

Example: When you entered the room, you

observed someone standing in the front of

the room, then inferred that is the teacher.

Influences

Several things can influence our

observations and our inferences

–Experience

–Knowledge

–Emotion

–Attention to detail.

Example

I observe that I see a swimming pool

I observe that my dog feels wet

I infer that my dog jumped in the water

Example

I observe that Nick is yawning

I observe that Nick has his head on his

desk

I infer that Nick did not get enough

sleep last night

OBSERVATIONS

That plant is extremely

wilted.

The car stopped running

INFERENCES

That plant is extremely

wilted due to a lack of

water.

The car stopped running

because it was out of

gas.

It’s important that we observe things

closely, because our observations may

trick us. That’s why scientists use tools

to gather their data.
