*Think about why you pick either option!

Write 4-5 sentences!

DO-NOW (WRITE IT IN YOUR “DO-NOW” SECTION!)

I NEED 4 PEOPLE TO SHARE THEIR RESPONSES!

“Evaluate the reasoning in arguments in which fact and

opinion are intermingled or when conclusions do not follow

logically from the evidence given.” (MN Science Standards)

What the heck does that mean?

LEARNING OBJECTIVE

“Our goal is to take a scientific claim

and see whether it makes sense. We

will be able to take a statement and

figure out whether it is opinion or fact.”

Science is about discussions!

Scientists cannot be stubborn when it comes to their data.

IMPORTANT POINT

Scientists cannot be stubborn when it comes to their data.

Science is all about proving your data wrong!

IMPORTANT POINT– WRITE IT IN YOUR NOTES!

In science, it’s a lot easier to prove

something WRONG than it is to prove something right.

What is a “logic?”

-Raise your hand quietly if you think you have a definition!

Logic: Logic is the science of reasoning. Logic helps people decide whether something is true or false.

DEFINITION OF THE DAY (WRITE IN YOUR BINDER)

No reptiles have fur. All snakes are

reptiles. No snakes have fur. 

But Mr. Herath….

WHAT DOES THIS HAVE TO DO WITH SCIENCE?!?!?

A good scientist is like a good detective. You have to figure out all of your clues, figure out what’s important and what’s not, and come up with a conclusion!

Mr. Whelan yel ls “JUMP!” at the frog and the frog jumps one meter.

Then he cuts off one of the frog’s legs, yel ls “ JUMP!” and the frog jumps half a meter.

Then he cuts off another of the frog’s legs, yel ls “JUMP!” and the frog jumps a fi fth of a meter.

Then he cuts off a third leg, yel ls “ JUMP!” and the frog does not jump. He yells “JUMP!” again, and the frog does not jump.

“Aha!” he says. “ I have my result!” So he careful ly writes in his lab book: “When three legs are removed, a frog becomes deaf.”

A BAD SCIENCE JOKE… *GROAN

What’s a better conclusion to reach?

WHAT DO YOU THINK?

Raise your hands!

A BAD SCIENCE JOKE… *GROAN

Science is based on arguments. Scientists love to prove each other wrong, since it gives them the best possible answers!

Scientists use logic to help figure out if something makes sense. Logic is the use of reasoning to make sure something makes sense or not.
