Could you pass 8th grade science??

I teach 8th grade science in California and this is not a California Standards Based 8th grade science test. If it was, I would have done better. 8th graders in California have to know all about Motion (graphing, d=rt, velocity, vectors), Forces (newton’s laws, f=ma, etc), density (archimedes principle, d=m/v, floating and sinking), Structure of matter (atoms, compounds, crystals and polymers), Astronomy (galaxies, stars, astronomical units and light years, planets), Reactions (law of conservation of matter, endo and exothermic reactions, pH of solutions), Chemistry of living systems (carbon, DNA, lipids, etc), and the Periodic Table (regions of PT, structure of atoms, properties of substances). 8th graders are basically learning what I learned in high school Physics and Chemistry. Even though the subject matter is more difficult, I am glad we are challenging our kids today - they can live up to it.

OMG, WHEN did they teach that in high school? I don’t remember any of that! I guess I’ll have to take the Lincoln & Mercedes back to the dealers, cuz I ain’t smart enough to drive 'em, being just a dumb old plumber working in the trenches.

Ranchwife,
You are saying you teach THAT to the “average” California 8th grader??.

Mark
PS: I graded a “C” . Guessed wrong on a few, like, gaseous planet???

Joe, You may be ignorant but your NOT OLD!!! :lol: :lol:
Try the Test again!!!

I’m ashamed, I missed one, and I was a high school science teacher for 35 years. My only excuse is that I’ve been retired for seven years.

Bob … :?

Marco~
Yes!! I wish there was some way to post one of my tests and have you all try to take it.

Have a good day!

I paid the smart-<expletive deleted> tax. I said that the final velocity of the item dropped was 0 m/sec because it would have come to rest when it hit. It DID specify a landing in the question. Oh well, I was just sharp enough to cut myself…

I am happy to say that I scored 100%. It is a fairly easy science quiz. All basic stuff.

Semper Fi!

Vt= the Square Root of (2mg divided by p x A x Cd).

Where Vt=Terminal Velocity
m=mass of the falling object
g= gravitational acceleration at the Earths surface
Cd = drag coefficient
p= density of the fluid the object is falling through
A= the objects cross-sectional area.

For that problem, it comes out to 100m/sec.

Semper Fi!

I think it’s impressive that we have so many people on this board with such varied backgrounds. I have two customers with Phd’s who routinely call me to “fix the mechanical stuff” which they just cannot seem to grasp. The Phd in Chemistry was impressed that I could change the flush valve in hit toilet in 15 minutes. He had worked on it all morning, and was totally frustrated. I was impressed that he knew what neutralized the chemical that spilled on my garage floor so I could stop the damage that was occurring.

If you did not fair well on the test, keep in mind that we each have our own unique gifts that we can share in different ways. A science test simply validates knowledge in that one area.

Everyone who passed the science test with 100% still has to pay $.55 for a Senior Coffee at McDonalds, just like the one who scored 50%. Life has a way of balancing it all out.

Welcome to the space age fellows! The kids of today are going to be living in the world of Star Trek, literally. Somewhere in our schools right now is the first commander of the first manned mission to Mars. In order for mankind to continue to explore, as is our nature, we have to leave this rock. Doing that in a meaningful manner requires new technologies, that requires science, that comes from more advanced mathematics.

You’re right about that. If I go to Ace Hardware (where one of my sons work), they will not even sell me a paint brush unless they call the house and get an OK from my wife. I am not allowed to work on our cars, my motorcycles or anything mechanical. Strange, because I have no trouble with electronics, computers, guns, bows, guitars and tying flies. We all have our strengths and weaknesses.

Semper Fi!
