Objectives SWBAT differentiate between

observations and inferences SWBAT take awesome science notes!

Why Do We Take Notes?

Taking notes helps us to learn Notes are a useful tool

If you don’t remember an answer, and you have good notes, you can find the answer in your notes.

When you review your notes, you get the big picture—how what you learn builds up over time and how it all fits together.

What Makes Good Notes Good? Good notes are written in your own words.

Good notes only contain information that helps YOU understand the material.

Good notes can be scanned quickly, so that you can easily find exactly what you’re looking for.

The Jhaveri© Method

Developed by world-famous scientist, Dr. Jhaveri.

Take a piece of paper, and fold the left side in toward the middle. The left side should be one-third the width of the paper.

Write name of lesson and date on top.

Key Points

All our lessons have 2-5 key points: the big, most important things that I want you to learn.

In the left column of your paper, we will write key points. In PowerPoints, key points will always

be red.

Key points go here!!!

Supporting Details

Supporting details are everything that help you remember key points.

On the other side of your paper, write down supporting details in your own words. YOU CHOOSE what to write down. Only write

down what will help YOU remember the key points.

Write supporting details in your own words. They’re only there to help YOU, so you need to make sure they’re in words YOU can understand.

Why Do We Do This?

Immediately tell the difference between super important facts (key points) and the things that help you understand them (supporting details).

Writing supporting details in your own words ensures that your notes are written in sentences that make sense to you.

Easy to find facts. Find the key point that the fact is about,

Boxing 1/14/09Muhammad Ali was born “Cassius Clay” in 1942. He changed his name when he found religion in 1964, and joined the Nation of Islam. Few people know the name “Cassius Clay,” but almost everyone knows the name “Muhammad Ali.” He is widely regarded as the most famous, and greatest, fighter of all time. As an amateur boxer, Muhammad Ali won an olympic gold medal, though he later threw it into the Ohio River after being refused service at a “whites-only” restaurant. This was the first, but not the only, of Muhammad Ali’s political acts. As the heavyweight champion of the world, Ali chose to go to jail rather than fight in the Vietnam War. Ali famously said, “I ain’t got no quarrel with them Viet Cong… they never called me n*g**r.” Ali was later allowed to fight again, when the New York State Supreme Court ruled that he had been imprisoned unjustly. He immediately fought to reclaim his heavyweight title, but lost—the first of his professional career.

Boxing 1/14/09Boxing is a

combat

sport

Boxing is the

world’s oldest

sport

Two people fight for 12 rounds.

Goal = knock opponent out.

If no one is knocked out, whoever has the most points wins.

There are 4

basic punches

in boxing

We’ve found 7000 year old drawings of boxing matches in Iraq.

Became part of Olympics in 688 B.C.

Jab = quick punch, front hand

Cross = powerful punch, rear hand

Hook = semi-circular punch

Uppercut = vertical punch

Always talkin’ ‘bout what you got…Look at the beakers on my desk.

In groups, you have 5 minutes to write down as many statements about them as you can.

Observation

Key Point #1: An observation is gathering information about the world through our five senses Examples:

I see that Mr. Jhaveri’s eyes are bloodshot

I hear that the music is loudI smell that poo is stinkyI taste that chocolate is sweetI feel that ice is cold when I touch it

Inference

Key Point #2: An inference is a belief made about an observation Examples

I see that Mr. Jhaveri’s eyes are bloodshot. I infer that he did not sleep much last night

I hear that the music is loud. My parents probably want me to turn it down

I smell that poo is stinky. So I bet that I should not rub it on my body

Mr. Jhaveri should give chocolate to students as a reward, because chocolate tastes sweet.

I feel that ice is cold. So I believe that it will cool down my cold drink

The Difference

Key Point #3: Observations are facts, and can’t be wrong. Inferences are beliefs, and can be wrong.

Example: Michael leaves the movie theatre, and sees that the ground is wet. So Michael thinks that it rained.

Observation: Andrew knows this by his sense of sight. Can’t be wrong.

Inference: explains the observation. But could there be any other reasons???

“Beyonce looks good”

Not an observation!!! It is not a fact that

Beyonce looks good. Some people disagree.

This is an inference!!! Whoever said this

believes that Beyonce is attractive because of facts: she has clear skin, shiny hair, an hourglass figure, etc.

Back it up like a pick-up truck Go back to your beaker sheet. Fold a new piece of paper in half.

Sort the statements into observations on the left and inferences on the right One sheet per person Do this on your own Can I get some volunteers to share their observations and inferences?

Candle Demonstration

Observe. What do you notice? Infer. What can you guess, based

on your observations? OH SNAP! What just happened?

Observations, please! OK, now give me some

inferences!

Observation or Inference? Part I This kid looks like a dork. The cowboy hat is brown. Cake tastes delicious. The bandana is red. I believe it is his birthday.

Observation or Inference? Part II Make five observations about the

classroom, and three inferences based on those observations.

Observations Inferences1. 1.2. 2.3. 3.4.5.

Key Point Wrap-up

Key Point #1: An observation is gathering information about the world through our five senses

Key Point #2: An inference is a belief made about an observation

Key Point #3: Observations are facts, and can’t be wrong. Inferences are beliefs, and can be wrong.

Exit Questions

In your own words, describe the difference between an observation and an inference.
