A cool science and engineering challenge for curious kids.

Speaking of science fairs, if you know of kids (grades 5-12) in the San Francisco Bay Area who are looking for a challenge, this one might be of interest:

It is not too late to participate in this year’s Tech Challenge. The Tech Museum of Innovation’s 21st annual Tech Challenge is designed to get at the heart of innovation for young people and is geared to the California Math, Science and Language Arts standards. This year’s Tech Challenge focus is on the need for safe clean drinking water. One in five people in the world do not have regular access to safe drinking water. The challenge: design a simple device to move water from the stream up to the village. With no electricity available, the flow of the stream needs to power the water mover.

An intriguing problem, no? Here are the challenge details:

Follow-up: why did the cheating poll for frosh engineering students have those answers?

In an earlier post, I shared the responses freshman engineering students had made (via electronic clickers) to a few questions I asked them during an ethics lecture I was giving them.
My commenters are pretty sure I left out options in the multiple choice that should have been included.
In this post, I consider some of those other options, and I try to explain my thinking in formulating the questions and the possible responses the way I did.
(Also, I’ll include the questions themselves, since the Quimble polls I used to present them in the original post seem not to be working at the moment.)

What freshman engineering students think about cheating.

In the freshman introduction to engineering class, where I am teaching the ethics module, the students have electronic clickers with which to respond in real time to (multiple choice) questions posed to them in lecture. I took advantage of this handy technology to get their responses to a few questions on cheating. I’m presenting the questions here in poll form so you can play along at home:

var all_polls = document.getElementsByClassName(‘quimble_poll_div’);
for (var i = 0; i < all_polls.length; i++) {
all_polls[i].style.width = '500px';
}

var all_polls = document.getElementsByClassName(‘quimble_poll_div’);
for (var i = 0; i < all_polls.length; i++) {
all_polls[i].style.width = '500px';
}

var all_polls = document.getElementsByClassName(‘quimble_poll_div’);
for (var i = 0; i < all_polls.length; i++) {
all_polls[i].style.width = '500px';
}

(In the event that Quimble is down and the poll is thus inaccessible, you can view the questions in this follow-up post.)
What do you suppose the students said?
