 Do you drink bottled water exclusively over tap water, or do you prefer tap water to bottled water?  *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.” IN YOUR NOTES SECTION!

 It’s cleaner  Tastes better  More natural WHAT ARE SOME CLAIMS YOU’VE HEARD ABOUT BOTTLED WATER VS TAP WATER?

 

HAVING A SCIENTIFIC MIND! 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 yells “JUMP!” at the frog and the frog jumps one meter.  Then he cuts off one of the frog’s legs, yells “JUMP!” and the frog jumps half a meter.  Then he cuts off another of the frog’s legs, yells “JUMP!” and the frog jumps a fifth of a meter.  Then he cuts off a third leg, yells “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 carefully 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! WHAT DO YOU THINK?

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. IMPORTANT POINTS FOR TODAY
