Since I've covered the big science story of the week in several other posts, I figured I'd combine the Review/Preview with the Fun Website of the Week this time out.
Week Two involved more review, and a greater understanding of the key elements of a controlled experiment, namely the manipulated and responding variables. REMEMBER: the manipulated variable is what the scientist changes, and the responding variable changes as a result. MORE
This week we will be reviewing metric measurement, and we will have homework on Monday and Wednesday. I also offered an extra opportunity to earn effort points - bring in a real-world example of the metric system in use! MORE
Topic: What do you think of the metric system? Should the US convert like Canada?
Fun Website of the Week:
Sandlot Science - lots of really cool optical illusions!

variables confuse the living mess out of me. They all mean almost the same thing ut they are different!!! It makes me mad but everytime i guess i get em right. and the metric system...been there done that past that test with flying colors but that was in math not science so that really scared me. Convert like Canada? Is the government really thinking that? Wow...First Letting President Bush live through his first inaguration.... or that thing after the election we're he says he swears to god....whatever...those government officials dont know a kitten from a nuclear bomb. Anyways why would we change. we have one of the best systems of measurements in the world. that and all the units are the right size..foots inches yards...yadayadayada. And they dont have thaat confusing hecta deci centi crap either. Changing our system to the metric system would make EVEN MORE confusing than life already is!!!! No wonder why George Bush's Approval rating is going down.. Bah No one ever liked him anyway. Yet no one liked al gore or john Kerry. Now Hilary Clinton wants to follow her husbands path in presidency!!!! You know...i thought his path had something to do with cheap motels...or is that just me?
ANYWAYS our unit system needs to stay the same or else they shall all be hurt in some way!!

Okay, I can't read half of your post, but the other half is just ridiculous. 1 meter equals 10 decimeters, 100 centimeters, and 1000 millimeters. Easy.
One mile equals something like 1048 yards, which equals somehting like 5948 feets, which equals some insane amount of inches. The Metric system uses an easy 1-10-100 system while the Customary system uses all sorts of confusing crap that don't match.
And, what does any of this have to do with our idiotic president?
ok whoa whoa whoa whoa whoa whoa!!!! Im saying IF our president did that....pay attention...anyways...ms green made it hard and stuffs....ur lucky u didnt have her..i think u didnt..whatever..ms green had a work sheet that made it easy but i lost it. anyways...how do u remember that stuff? also.... i cant remember the order of the hecta centi deci..blah blah blah...

Hello, folks!
First, no one in the current administration is suggesting that we just convert to metric overnight (at least not that I have heard). It's been debated since Jimmy Carter was president (back in the bad old 70s). Canada just did it - went metric. We have metric measurements in medicine and soda bottles, but not in many other things - in some we are "bilingual" - like temperatures posted on bank signs. I was told in fifth grade (1975) that this was the "wave of the future" - well, I'm still waiting on jet cars that fly like the Jetsons, and a colony on the moon like the movie "2001."
On remembering the metric system:
Try Kangaroos Hopping Down Mountains Drinking Chocolate Milk - the first letter of each word corresponds to a metric prefix. K for kilo, h for hecto, and so on.
Another nice thing is that the prefixes are consistent whether you are measuring liquids, length or mass - no ounces, inches, or pounds to worry about.
For another argument in favor - read the linked article about how the Mars Orbiter mission as a failure due to a measuring error:

hay mrsq. its been a while since i checked the blog, but when i did i was delighted to see that there is a study guide type thing posted on the blog. it appears that it will come in handy when studying for your test and quizes.thanks
luke the cook
Delighted! Such large words for you, Lucas!
Just Kidding.
STEVE IRWIN DIED!!!! in a freak stingray accident while filming a documentary on "the oceans deadliest creatures" I cant beleive he died, it's rather depressing to tell you the truth. I know this isn't exactly "science" related but he really was an important person.
^gabysutton
Yeah....I heard just a few minutes ago...
Dang, I am so freaking sick. My head is throbbing, I feel hot/cold, my nose is stuffed, and my throat hurts...
PAMPER ME!
Gabby and Gabriel (and everyone else, too)...
I also just heard about Steve Irwin dying (I heard it on the radio on my way home from the store). It is VERY sad, and very much science related! He was a wonderful example of how learning about the world could be fun and entertaining.
It was truly a freak accident - the stingray barb actually put a hole on his heart. While stingray stings are very painful, they are not usually fatal.
I'm putting together a full post about it - look for it later on today.
Keep his wife and kids in your thoughts!
How can pluto not be a planet anymore?? This is simply crazyness. i think they should make the other objects like pluto (pluto planets) planets and then pluto is still a planet. it would be so much better. have they come up with a name for the type of thing pluto is?? its not a planet or a crator or anything else so what is it?? that is weird.
<3 allison levy
I wonder if that since Pluto is so far out in space it could be a planet to another sun or other type of powerful star
Should the US convert over to the metric system?-
yes, i really think that we should! my reason being that we are so differnt from all the rest of the world. the metric system is what is used practically everywere excep here. what if i moved to england and didnt know how to measure anything? the metric system is also used in scince. if the US converted to the metric system, it would benefit greatly!
i wonder how different its gonna b with kids in younger grades who just learnd the9 planets and nowhaving 2 foet about the last 1..pluto
Allison - your idea of making Pluto and other objects like "planets" is actually what was originally proposed. If the IAU had done that, we would have three new planets: Charon (Pluto's moon), Ceres (currently an asteroid), and 2003 UB313 (nicknamed Xena).
I like the new definition - Pluto was always different - the new definition explains why. It will still have a special place becuase of it's role in the debate!
Ashley, I wonder what the kids will think, too! This is kind of minor though, compared to some of the changes scientists have discovered throughout history. Can you imagine being a kid in the 1400s, learning that the world was flat, and that everything revolved around the Earth, only to wake up and find that the Earth was round and went around the sun?
Yikes - I think that would be harder to learn!
Sarah - I agree, we've waited too long to make the change - it's a global economy, and we need to think on a global scale!
I think that we should, at some point within a few years, convert to the metric system. We would then be with the rest of the world, and it would not be as confusing as to have to know BOTH systems.
Nick - I agree 100%!!!
Mrs.Q. and Nick, that would confuse me converting to the metric system, I dont need any more confusion in my life!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Loren
Haha the optical illusions are so cool
Loren - part of why the metric system is so confusing is that kids are taught one way, and then all of a sudden, they need to learn a new way! If we just taught one, it wouldn't be confusing (and metric is the easier of the two).
