cress seed orientation in microgravity project cress seed orientation in microgravity project The directions say "The micropyle on each seed should point downward, in the direction of the arrow." Does this mean the micropyle is "down" as in parallel to the arrow, or literally pointing towards the arrow (so the seeds on the sides are at an angle)? Or perhaps it means "down" as pointing to the base of the petri plate when it is sitting flat on the table? Thanks for clarifying this. Re:… Read more

Re: Specific Heat Capacity Question Re: Specific Heat Capacity Question (Sorry, didn't read the guidelines as well as I thought! Updating this post with proper grammar.) Hey! This is probably not that great of a question, but I'm unsure where else to ask - I'd ask my teacher, but we're in the midst of winter break right now. In this ScienceBuddies project, the q=mCpΔt equation has Cp as specific heat capacity, which the project states is .001 when converting to kCal. However, in class and… Read more
