The way the rules are written under 3.b "The launching force must be entirely supplied by the gravitational potential energy from a falling mass less than or equal to 3.5kg (Div C); 5kg (Div B).... This leads me to believe that whatever mass is in use at the time of launch must fulfill the wei...

A lot of people seem to not know about this, but Science Olympiad will often post FAQs about unclear parts of the rules. In Air Trajectory this year, this FAQ states that manually supporting the weight with a string or other form of cable is not a valid trigger device. This means that if you let go ...

I've been working on a spreadsheet recently that automates many parts of tournament scoring in Science Olympiad, and it's finally finished. From creating a scoresheet for release to generating a slideshow for award ceremonies to making histograms of individual events, the spreadsheet has a lot of us...

should I worry about scientific name synonyms? Right now I have common name synonyms on my notes, but I'm wondering if I should put these (listed on wikipedia) - I'll use balsam fir as an example. Pinus balsamea L. Abies balsamifera Michx. Peuce balsamea (L.) Rich. Abies hudsonia Bosc ex Jacques Pi...

Hi all, for trajectory when we launch, can our launcher shoot towards the diagonal of the square restriction, or must it shoot towards a face? I have asked around, and no one has said that this diagonal orientation is illegal, but they have noted that they have never seen anything other than the re...

Hey y’all! I was the event supervisor for Trajectory C at last weekend’s Seven Lakes Invitational. Firstly, congratulations to all of the teams that competed! The quality of devices that I saw was incredible, and I could tell that a lot of work went into each aspect of your devices. Overall, I felt ...

This was answered in last year's forum here.
If I understand this right, your board is your tee holder, and that would mean that it is fine to be within the 10 cm.

Next question: What is a relay and how does it work? A relay is an electrically controlled switch, kind of like a transistor. It can work in multiple ways, but one way (the most common way?) is for it to use an electromagnet. The electromagnet controls the switch by moving a conductor into position...
