1. DO the 2nd and 3rd graders need to know the spellings too, i mean would they be checked on spellings as well
No. As long as the word is recognized by the grader, it will be graded as correct. The only exception is if the spelling is so mangled that it cannot be recognized - then we cannot tell if it is correct or not, in which case we will mark it as wrong.
2. Is the plan to have the planetarium test yet ?
I may not understand this question completely. There is a dome test portion of the event, on the day of the event. Because the museum of natural history is closed this year, it is not clear whether we will be able to have a practice in a planetarium before the event.
3. I have 2 kids in each grade, Are they both expected to write answers together or do they get separate answer sheets ?
A team collaborates on a single answer sheet.
4.Are they allowed to carry any material or hand written info , i do understand they are allowed to carry the scientific calculator .
No material can be brought into the event. A scientific calculator should be brought to the event for 4th and 5th grade teams.
