Re: Science Olympiad at Penn Invitational 2019

Hi, I am not in your area, but have a general question on fossils. Since you wrote a fossils test, I am wondering where you get the information on temporal range of fossils for the answer key and what is considered main resource for regional/state/national test. We checked several resources and not...

Re: Science Olympiad at Penn Invitational 2019

Hey everyone! I was one of the event supervisors for Fossils and this was my first time writing a test, so any feedback and criticism would be super helpful. Hope that you guys liked the tournament!

Re: Robot Arm C

First of all, good luck to all the teams competing in New York! Could I ask that someone post the raw scores from today's event? I was supposed to compete today, but my school wouldn't let us travel to Syracuse because our school had a snow day on Friday. I just wanted to see how my arm would compar...

Re: Materials Science C

Just wondering, do we have to learn calculus for this event? I'm a junior, so I take calculus next year, but I noticed that derivatives are used to determine creep while differentials are used to determine viscosity. In other words, do we have to compute numerical for creep or viscosity, or are we g...

Re: Robot Arm C

Just out of curiosity, if an item is fully supported by an end effector, which is fully supported by the goal cartons, does it count? In other words, can transitivity apply to the objects, end effectors, and goal cartons. Thanks!

Re: Simple Machines B/Compound Machines C

I understand that, but the problem is that the ratio between d1 and d2 is that the mass of the bar prevents finding an equal ratio. I've tried tests with 2 known masses, and I found measurements to create equilibrium with 2 200g masses, but not 2 20g masses. Does anybody else know how to figure out ...

Re: Simple Machines B/Compound Machines C

I've done simple machines in middle school, but does anyone knew how to calculate the ratio between 2 masses with the compound lever? My problem is that the mass of the arm of the class 2 lever complicates the equation(l1*w1 = l2*w2) without knowing at least one mass.
