Perfect Paragraph

Try to have consistent tenses when writing. 

Good paragraph! I'd just watch out for the use of the present tense in scientific writing. 

This is a godd paragraph because it show cases actions that were taken that received a response from the spider. However, the personal use of "I" was used, and in scientific writing we should try and withhold any human interaction. Instead, try phrasing around what you did. Instead of saying " I shined a light" say " a light was shined", or instead of " I can't be sure without magnification" use " magnification is needed for clarity".

I liked the way you painted a picture in the reader's head of the spider.  The only comment I have is to try to connect one sentence to the next.  At one point you say "This stopped after 10 minutes, and the spider is now hanging on its web again."  Although it does seem repetitive to say "the spider's rapid movements stopped after 10 minutes..." scientific writing calls for clear pronoun usage.  It does seem silly but technically you could be referring to dropping the container when you say it stopped after 10 minutes.  There are some examples of how to use clear pronouns on page 23 of the Writing in the Biological Sciences book.  Also, there is some rule about not starting a sentence with "This" but that may not be true anymore.  I really liked your paragraph, though! Keep it up!
