If you answer please give a rationale.
Which of the following would have the capacity of 1 milliliter?
a.water bottle
b.paper clip
c.1 DROP from an eye dropper.
d. small fingernail.

"Capacity" means the amount of a substance that a container or vessel is "capable" of holding.
So I would say the eye dropper, since a paper clip and a fingernail wouldn't hold a liquid, and a water bottle would be capable of holding much more than a ml.

If you were to read more carefully....
c. 1 drop from an eye dropper, not an eye dropper.

I did read it carefully. 1 drop from an eyedropper would be much closer to 1 ml than any of the other options.

paper clip - I can bend it into a shape that will hold 1ml using capillary forces.
I have really really tiny hands.

Probably d. small fingernail. Because the fingernail (otherwise known as keratin) is made from the human body which is made of about 70% water. I believe a milliliter is about 20 drops, I could be wrong. We had this question in elementary school, trick question.

Either the Jolly Green Giant's eye dropper or Tom Thumb's water bottle.

a. Water bottle
Water bottle has a much greater capacity than 1ml so it certainly has the capacity for a smaller volume of 1ml. An eye dropper might have the capacity for 1ml but a single drop? Not likely. Volume of a paper clip or small fingernail would seem to be less than 1ml so they are unlikely choices. I can see where a more sophisticated solution involving a paper clip or fingernail might be possible but since the question is directed towards elementary aged kids, it's probably meant to be a simple exercise in recognition of the volume of 1ml.

The "answer" is C.
C can't really be the answer for two reasons. 1. The question states that the answer will have CAPACITY. While a drop has mass and area it does not have any capacity. Does a bowling ball have capacity?
2. One hanging drop of water is 1/20 ml not one ml as the question implies.
When I brought this to the attention of my son's teacher she told me she would speak to the "Science Cadre" and revise it for next year.
Then, I got an e-mail from the cadre
representative that flat out defends the question and answer," This would be the most logical response since it is the closest to hold a milliliter (SIC)", I wrote to the principal and the board. The only response that I have received so far is that the "District Science Coordinator" is reviewing my question.
The "science cadre" should take more time writing clear,cogent and fact based test questions and less time defending faulty questions with twisted logic and garbage.

If that was the case then hundreds of developments that make no sense on paper would have been discounted before they were even conceived.. Sounds like crap and smells like crap and is being feed to our children.
Enjoy that stadium. Maybe our kids will be qualified to cut the grass there.

Your point is correct - capacity is generally defined as the maximum amount that something can contain (such as the new stadium has a new seating capacity of 5,000). So, if the question had been about the eye dropper, it would have been fine, but since it was the liquid it is incorrect.
Sounds like the person who developed the question doesn't want to lose face by admitting it was a poorly designed question. A shame for both the kids and the test creator.

As a parent, if I sincerely felt my children were not receiving a quality education attending the schools within the district I lived, I would not hesitate to move, send them to a private school, or home school them! I am new to this forum, but from the posts I have read I get the distinct feeling that safety and quality are lacking in your opinion. I would NEVER subject my children to such an inferior education if I had such strong beliefs! I guess I am wondering ... Why do you allow your children to suffer in such an unsafe and low quality system?

Are we cross? If I thought we couldn't be friends I just don't know if I could bear it.

I'm your huckleberry! I have no reason to be cross ... and consider you neither friend nor foe! I am just sincerely curious how a parent could be so seemingly distraught about his child's education (to the point of only being able to cut stadium turf) and not make a change. My guess is that the school must not be quite as bad as it is portrayed!

I've been wondering the same thing myself for quite some time. If I was sooooo dissatisfied with my children's education specifically in AISD, I'd do something about it.

This reply is to the thread in general. Yes, the question is poorly worded. One poorly worded question hardly indicts an entire program. I have seen enough from the OP to believe that the tone of his message to the science coordinator probably immediately put him/her on the defensive, hence the defensive response. That is human nature. I think we have bigger fish to fry

I had many tests in college where the professor purposely worded questions this way and instructed the class to choose the most correct or least wrong answer.
I've also run across numerous such situations in professional certification testing.

You are correct. One poorly worded question is not the end of the world. It was the defense of the question and the statement regarding ...logical and reasonable answers that are the biggest issue with me.
