Re: Crave the Wave B
Hello. So I’ve been studying waves, and I don’t understand the difference between the medium and the actual wave. I get that the medium is what the wave moves through, but then what’s the actual wave? I’ll use the slinky coil as an example. When u vibrate your hands on one end, a wave passes throug...

CDC says this is cohort, but i dont think this is an epidemiological study. INsi...

Re: Remote Sensing C
Does anyone know what to expect from RemSen tests this year? I try to learn conceptually and have a great background in Earth science, so I'm hoping to do well, but I'm afraid my weakness will just be memorization of terms, satellites, etc. The rules seem to be ideally geared towards more conceptua...

Re: Circuit Lab B/C
Ok, here are some easy ones since I can't think of any hard ones: 1) What direction do electric field lines created by a stationary proton point? 2) Do ferromagnetic metals retain their magnetic property? If not, state what needs to happen for its magnetic property to be "activated." 3) A...

Re: Disease Detectives B/C

Interpret your result. 6.95? The people who ate the pork is more likely than not to get the illness Yep! You can ask ...

Re: Pennsylvania 2021
Thoughts on PA teams at rustin (based on superscore): Springhouse was above all the other PA teams by a decent amount (260 vs 384 points) I was surprised about how well Mountain View did, they beat Eagle View by a significant amount (last year, Eagle View was slightly better than them) I don't real...

Re: Pennsylvania 2021
Been 2 years since I last competed at Rustin... amazing that's it's gone from a 60 team invitational to 125 teams this year. Looks like it'll be close between Kennedy and Jeffrey Trail in div B, but I haven't been keeping track of many div B teams this year. If only tournaments could be this many t...
