It's About Time C

[Science Zone]

Hi, this is my first year trying out It's about time, and I would like to know that if anybody can tell me that if there any impound for it's about time or not. I just want to make sure that there are no sign up for time slot. The time is already designated for us. That would be all thank you

The rules say that there should be an impound, however, it's up to your regional or state director whether or not they want to implement it. In my state, MA, we have impound and we sign up for a 10 minute time slot. I would contact your director for the details.

What region are you in?

Hey I was thinking about building an escapement for a pendulum and I wanted to use metal gears but does this go against the part in the rules where it prohibits using commercial parts of timepieces?

Any thoughts would be appreciated.

From the clarifications page:

# It's About Time

(section: 3 / paragraph: b / line: 1)
* 11/29/2009 - 14:32 Are we allowed to buy gears and escapements to build our time piece?

Yes, as long as the parts bought are not explicitly made / sold for use in time keeping devices. For example, an escapement that is sold as a replacement part for the grandfather clock would not be allowable, whereas a generic gear sold for use in a toy car would be allowable.

Can i get a practice test for It's about time. thanks in advance

Here's the best I've got: http://www.scioly.org/wiki/2009_Test_Ex ... About_Time

Here's an idea that my school might end up using at states.

A Stirling Engine converts ambient heat into kinetic energy in a flywheel via volumetric changes in a cylinder, and a temperature differential between a hot and a cold chamber. If you built a Stirling engine (very precisely, or course, since they are notoriously persnickety to build) and embedded the cold chamber in a cooler of ice, and focused a parabolic mirror onto the hot chamber, the resulting difference in temperature should be enough to get things moving. All you'd need to do was come up with a way to gear it down to read the time more accurately. So essentially, you'd impound a camp oven and a cooler of ice : )

Any thoughts?

When you say "camp oven" are you refering to the parabolic mirror or something else? Can a parabolic mirror heat something from flourescent lights?

Well, that's one thing we're going to test, whether a arabolic mirror can be focused on a 60 or 70 Watt bulb at several feet and have a noticeable difference. It could be that the ice itelf is enough
