The only person you should try to be better than is the person you were yesterday.

1. Choose a book from our bookshelf in the back of the room (you may also read your own book if you have one with you).

2. Read silently at your desk until 8:40 am.3. At 8:40 am, please, silently put away your

books, take out a pen or a pencil and a sheet of paper.

Catalyst September 2, 2014Write the homework down in your science

notebook and in your agenda.Homework: Complete your review worksheet

DUE TOMORROW.Directions: 1. You will have 5 minutes. 2. Look at the decorations in this room. 3. Write down as many things that you notice as

you can about the decorations. You can include colors, shapes, common themes, similarities, differences, etc.

Do your homework, and win prizes!!!

Please set-up your notebook like this:

Notes: Scientific Skills September 2• When you see writing in PURPLE, that means it is

something you need to WRITE DOWN.

• Example:– The scientific method includes the steps that all

scientists take to make sure they get accurate results.– The first step of the scientific method is to identify the

problem.

What sentence would you write in your notes?

What is the Scientific Method??

Questions come from observations!

What is an observation?

• Observation – something that you notice using your 5 senses (touch, taste, sight, sound, smell)

Example?

Observation Race!!

Rules:• You will have 1 minute.• At your desk, you will write down as many

observations as you can about our class and our classroom.

• Keep writing until the timer goes off!!• You cannot repeat the same observation more

than once.• The student with the most observations wins

a table group point!!

Observation vs. Inference

Observation:• Uses your 5 senses

to describe something

Inference:• Uses your

observations to make an educated

guess or a prediction

Observation vs. Inference• Observations can be turned into inferences. • Example:– Observation: It is colder in Mr. Davis’s room

than in Ms. McNeirney’s room.– Inference: Mr. Davis’s air conditioner might be

set to a colder temperature than Ms. McNeirney’s.

Your turn!• You will have 30 seconds. • Choose one observation that you wrote

down during our observation race. • Turn it into an inference.

Volunteers?

Practice!!• My Observations:• I hear music and people yelling.• I smell cotton candy, popcorn, and hamburgers.• I see a lot of people.

• Inference = ?

Practice!

When I say go, come up with one observation and

one inference with a partner at your table.t

Write your observation and your inference in your notebook! sets of animal tracks.

Now what do you think?

Make 1 OBSERVATION.Make 1 INFERENCE.

Now what do you think?

Make 1 OBSERVATION.Make 1 INFERENCE.

Quantitative vs. Qualitative• Scientists use their observations and inferences to

collect data. • There are 2 important categories of data.–Quantitative – can be measured, deals with

numbers (think: quaNtitative = Numbers)

–Qualitative – describes things that can be observed but cannot be measured; qualitative information does not use numbers

For each picture write one quantitative observation or question and one qualitative observation.

For each picture write one quantitative observation or question and one qualitative observation.

Think-Pair-Share• On the next slide, there will be observations

and inferences. • By yourself or with a partner at your table,

identify whether each statement is an example of qualitative or quantitative data.

• All partners must write down the example AND the answer in his or her own notebook.

• You will have 3 minutes to record your answers. I will call on students randomly, so be sure you have something to share.

Qualitative or Quantitative?

1. Sailfish can swim up to 67 miles per hour. 2. Adult sloths, elephants, hippos and rhinos

are the only mammals that cannot jump.3. Penguins can jump up to 9 feet. 4. I think that baby otters are cuter than baby

parrots.

Let’s put our knowledge to the test!•

http://studyjams.scholastic.com/studyjams/jams/science/scientific-inquiry/scientific-methods.htm

• When you watch this video, be on the look out for the observations and inferences that the characters make.

• Pay special attention during the experiment and the conclusion to what kinds of qualitative and quantitative data the characters gathered.

Check Your Learning!You will answer the questions on the next slide in your notebook:

- 1’s will answer all odd number questions.- 2’s will answer all even number questions.

• You MUST answer all of the questions in complete sentences, and you must RTQ!–Who can remind me what it means to RTQ

(restate the question)?

Check Your Learning!

1. What did Mia observe about hummingbirds that led her to create an experiment?

2. What was her inference about the bird feeders?

3. What other word did they use for inference? (Hint: It was one of the steps.)

4. Give an example of qualitative information that they tested.

5. Give an example of quantitative information that they tested.

Share Out!

• You will have 2 minutes to share your answers with your partner.

• Make sure that you both agree that the answer is correct.

Volunteers?

The bigger picture…• We are about to express opinions. • During this activity, we will remember:– There are no right or wrong answers. We are all

entitled to our own opinions.– We will listen and contribute respectfully.– Everyone will participate. – We should be building off of what people said by

starting our sentences using:• “I agree with ________, because…”• Or “I disagree with ________, because…”

Take a Stand!

• Which is more important, qualitative or quantitative data?

• Should an experiment have just qualitative or just quantitative data?

• What are the benefits of using quantitative data?

• What are the limits of using quantitative data?
