- 9:52 am
- Bugscope Teamjust starting setup for today's session
- 9:57 am
- TeacherNo worries...getting the kids settled. Did you understand the samples?
- Bugscope Teamyes thanks for labeling the bags :)
- 10:02 am
- 10:14 am
- TeacherDid the samples match up correctly?
- Bugscope Teamthey seem to be perfect
- Bugscope Teamperfetto
- Bugscope Teamplease let us know if you have an preferences for today
- Bugscope Teamthis is the crime scene evidence
- TeacherSweet! They are chomping at the bit!
- 10:22 am
- TeacherIf you will start with the crime scene that would be super. They are filling out evidence collection forms and then a form to sketch a sample of each suspect.
- TeacherI am going to start geting them to the computers...is that ok?
- Bugscope Teamyes go right ahead!
- Bugscope Teamcool!
- TeacherDo the kids login as 'guest'?
- Bugscope Teamthey can
- Bugscope Teamor Students if that is available
- Bugscope Teamit doesn't matter if they are on as guest or student
- Bugscope Teamsometimes, for some reason, the Student option is not available
- TeacherI don't see it in the drop down.
- Bugscope Teamyeah so Guest, which is presumably there...
- 10:27 am
- TeacherWe refreshed and the student option appeared. :)
- Bugscope Teamhi everybody!
- Bugscope Teamsweet
- StudentHello Cate! Good Morning
- Bugscope TeamHello Everyone!
- Bugscope Teamthis is the crime scene evidence sample at relatively low magnification
- Bugscope Teamthese are all live images from the samples that are in the microscope
- StudentIs this the pictureof the shoelace
Bugscope Teamyes! you can see the way the fabric is woven
- Studentwhats that stuff that looks like dots
Bugscope Teamsomeone on your side can investigate, take the magnification up, to see what those dots might be
- StudentIs that dirt?
Bugscope Teamthere might be some dirt on there, but most of those specks are pollen grains
- Bugscope Teamlooks like the perp was walking through a garden or something
- StudentThose pollen grains may have gotten into the shoe because The evidence may be from the two jocks, Thugston and Jockette
- Bugscope Teamis Jockette a woman?
- Studentyes she is
- StudentHe was hiding in a bush, kind of like a garden
Bugscope Teamwow that could be helpful
- Studentyes she is.
- 10:33 am
- StudentInever realized how big pollen was
- StudentWow! 592x magnified!
- StudentIs this the pollen up closer in bigger magnification?
- StudentAre those strings thread from the shoelace?
- StudentIOn the form it says that a woman called a complaint of someone stomping her garden. that mught be the pollen
- Bugscope Teamthey are still realyl small. You don't get this magnified with standard light microscopes
- Studentin the evidence one of the witnesses said her flowers were trampled, so that could be the reason for pollen on the shoelace
- Studentso what are thoes things that look like dotes on the pollon.
Bugscope Teammaybe you could take the magnification up to see
- StudentThey're pollen grains
- Studentwhat is that?
- Studentis this still the shoelace
- StudentWhat is this?
Bugscope Teamthe flattened basketballs are pollen grains found on suspect A
- StudentIs this like crumbs that fell and landed on the shoelace?
- StudentIt looks like a rock
- Studentoh, this is the pollen grain!
- StudentSo this is a gumdrop or a basketball
- Studentits the pollen
- Studentwait, the the big thing in the middle is pollen ?
- Bugscope Teamwe can see that the pollen grains are inside those two larger pieces of vegetation
- Studentwhats that big wall looking thing.
Bugscope Teamthe strings are parts of the shoeslace. the big parts are part of the plant that the pollen came from
- Bugscope TeamI think those are anthers.
- StudentSo it's part of a plant?
- StudentWhat are anthers?
- StudentWhat are anthers?
- Studentwhats an anther?
- 10:38 am
- Studentso its the plant stuck in the shoelace
- Bugscope Teamanthers are the parts that stick up in the middle of the flower and often have lobes on them -- they are full of pollen
- StudentOoh, because whoever's shoelace this is was in the woman's garden, & thats why there is pollen & vegetation on it
- Bugscope Teamif you walk through grass even you could get pollen on you
- StudentVery fascinating
- TeacherI believe there should be grass pollen &/or seeds on all samples. Remember you are looking for something different that would match the crime scene to one of the suspect samples.
- Bugscope Teamyour teacher is right
- Bugscope Teamthere are different pollens on the samples. you have to try to match up what suspect sample seems to match the crime scene evidence
- Studentis this part of the shoe lace or is this another piece of pollon because it looks like there is less pollon on it than the shoe lace.
- Studentso this explains about the women complaing about her garden, this is the anther of her flowers.
- Studentoh makes sence now.
- Studentokay, so it doesnt matter what sample it is because they all have pollen because they were all found in the dit?
- StudentIt looks like there is alot of pollen on this sample
- Bugscope Teamthis was on suspect b
- Studentthis shoelace looks smoother than the last
- Bugscope Teamthey have football shaped pollen grains
- StudentIs that normal?
- Bugscope Teamit could be, but I would focus more on the kinds of pollen you see
- 10:44 am
- Studentthey must have ran though the bush because they have more pollen
- Studentand its football shaped!
- Studentyes i beleive so
- Studentit looks like hair\
- StudentThere is alot of pollen.
- StudentThe pollen on here looks different from suspect a .
- Studentdo they come in different sizes and shapes
Bugscope Teamyes they do! Some are football shaped like here. Some may look more like deflated basketballs. And some may look spikey (which is what ragweed looks like)
- Bugscope Teamwe've seen pollen like those football-shaped ones before
- StudentThe pollen is very numerous here
- Studentis this suspect b
- StudentThis looks more oval-Shaped and less pointed tip than suspect b and a
- StudentThere is a numerous amount of pollen
- Studentso does that mean that they were walking on differentplaces/
- Studentwhat plant dfo they come from is it on most plants
- StudentWhat is this?
- StudentThis looks like a cell?
- StudentIs this a peice of pollen?
- Bugscope Teamthis is a pollen grain trapped in the shoelace
- Bugscope Teampollen comes in different shapes and sizes
- Studentit looks like a pea in a fork
- StudentThe pollen from sample A and C look similar
Bugscope Teami think you are right.
- StudentSample B is the only one that is distinctively different from the others.
- StudentThe woven parts of sample B and the crime scene evidence look similar
- Studentwhat about there color
Bugscope Teamwe could see the color before we put these samples in the sputter coater and coated them with gold-palladium
- 10:49 am
- StudentSo now we know that it is probably not suspect a.
- StudentThe shoelace's length is about 2mm, is that correct?
Bugscope Teamall of the shoelace samples were closer to 9 or 10 millimeters, but we actually cut some of them smaller so they would fit on the stub
- Studentokay, thanks
- Studentits fabric
- StudentWhat is that stringy looking stuff?
Bugscope Teamthose are the fibers of the threads that the shoelace is woven from
- Studentoh so do they come in different colors and sizes?
Bugscope Teampollen can be different colors and sizes. We can only tell sizes in this microscope, though, because everything is in black and white
- StudentThis looks similar to sample B
- StudentWhat are the things that look like is ripping off paper like
- StudentThis sample looks a lot like sample B
- StudentThank you!
- TeacherWe are switching now.
- StudentAre the fibers on the shoelace torn ?
Bugscope Teamthe fibers were cut; if we were to look at the ends, we would see that they have been crushed by a blade, like scissors, and that seems to indicate that they may be some kind of polymer
- StudentThank you have a very nicce day~
Bugscope TeamThank You!
- Teacher8th Period begins
- 10:54 am
- Bugscope Team8th Period? Goodness, what time did you start school today?
- TeacherThey are all here...this is just how they are grouped.
- Bugscope Teamsuper cool!
- Bugscope Teamare Thugston and Jockette there too?
- TeacherI can't get suspect A...
- Bugscope Teamwe can't get it either -- Cate is driving directly there
- Bugscope Teami think it all works now
- TeacherOk. That looks good. They are ready to sketch now.
- Bugscope Teamthis, now, is Suspect A sample, high mag
- Studentit looks like teeth
Bugscope Teamyes like teeth!
- StudentWhy do the circle things have dents
- 11:00 am
- Studentis it cells or something?
Bugscope Teamthese are pollen grains on suspect a's shoelace
- Studentdirt or pollen?
- TeacherRemember we are looking at a piece of shoelace. What might you find on your shoes, other than poop?
Bugscope Teambits of food from messy eating?
- StudentAre the things that look like blood cells pollen?
Bugscope Teamyes they are! pollen comes in different shapes and sizes
- StudentIs there alot of pollen in the shoelace?
- Studentit looks like corn
- StudentAt first i thought they were red blood cells.
Bugscope Teamthey look a lot like red blood cells, which are biconcave discs about 8 to 14 microns in diameter
- Studentare we looking in between the fabric?
Bugscope Teamthere is a piece of the plant these pollen grains are sitting in and then the long stringy things here are the shoelace fabric fibers
- Bugscope Teamhuman red blood cells do not have nuclei, but those of birds do
- Studentwhat is in this?
Bugscope Teamyes! more pollen!
- StudentSo for suspect b, the pollen is stuck in the fabric?
- Studentwhy does it look diferent than the last one if they are both the same material?
- StudentWhat are the smaller particles?
Bugscope Teamjuju and perhaps other types of pollen
- Studentwhat are the pore like things?
- Bugscope Teamlily pollen looks a lot like the football-shaped pollen grains we see now
- 11:05 am
- Studentthey look like they are floating
- StudentDoes that mean that the suspect could have run through some kind plant
- Studentcorn agian?
- Studentlooks similar to b
- Studentis that hair in the back?
- StudentThat looks like the pollen we saw in suspect a's sample
- Studentthe object toward the bottom, What is that?
Bugscope Teamthere are fibers that make up the threads, and there is one tiny gumdrop-like pollen grain that also resembles a mold spore, and there are football-shaped pollen grains
- Studentwhat are those lines coming off the hair
- StudentIm guessing the little sphere looking object is more pollen.
Bugscope Teamyes it is pollen
- Bugscope Teampollen can look different on different plants
- Studentwhy does the pollen look totally different under the microscope?
- Studentdoes the lack of pollen symbolize less physical activity than the other suspects?
- Bugscope Teamsome can be spikey, some can be football shaped, and some can be like deflated basketballs, for instance
- Studentit's hair and polin
- Bugscope Teamso this pollen looks more like a football
- Studentsome of the strands have stuff coming off of it like on the far right what is that stuff?
Bugscope Teamthat was, I believe, smaller bits of the polymer the threads are made of, as thin as spider silk
- Bugscope Teamthe hair is really fibers on the shoelace
- Studentoh, ok
- Studentthat looks kind of like suspect b
- Studentthis looks like a mixture of all of the types of pollen we've seen so far
- 11:10 am
- StudentThe little objects on the strands, is that some kind of pollen?
Bugscope Teamthe oval shaped things are the pollen. There is some dirt and other plant fibers here too
- Studentthe cells on the pollen is very distinct]
- Studenthave a great day, Bye.
- Studenthave a good day bye
- StudentIt looks like B
- Bugscope Teamhope you had fun!
- Bugscope Teamoh no where are you going?
- Bugscope Teamwhere's Thugston and Jockette?
- Bugscope Teamokay Bye!
- Teacher5th period
- Bugscope Teamso on these different samples you might see different shaped pollen grains
Bugscope TeamHello Group 7E!
- Bugscope Teamnot all pollen grains will look alike
- 11:15 am
- Studentwhat are those things in the middle?
- StudentThe corn shaped things are pollen grains?
- StudentSo this is A shoe string?
Bugscope Teamthis is on the A shoestring
- Bugscope Teamthe deflated balls are the pollens
- StudentWhat type of pollen?
- Bugscope Teamthey are actually sitting in a little bit of a piece of plant right now, and the plant is sitting on the shoestring
- Studenthow come the clumps in between are seperated?
Bugscope Teamif you took the magnification down lower it might make more sense
- StudentIs that dirt in between the fibers?
- Studentwhat is the crevasse to the left of the pollen
- StudentPollens, so does that mean the suspect this is from could have been near plants?
- StudentWhat is that cave looking thing on the left?
Bugscope Teamit's part of the anther
- StudentWhats an anther?
- Bugscope Teamnow you can see what we are looking at
- Studenti cant even tell what is
- Bugscope Teamthe strings are the fibers of the shoestring
- StudentIst that still the shoe lace?
- Studentwhat is this rough looking thing
Bugscope Teamthat is the anther that the pollen grains are sitting on
- StudentIs this Shoe String "B"?
Bugscope Teamwe are on A
- StudentWhat is the fibers around it?
- Bugscope Teaman anther is the part of the flower that sticks up in the middle
- Student so the rough looking thing is the pollen right?
- Studentwhat are those speggetti type things?
Bugscope Teamthose are the fibers the threads are made of
- TeacherMoving to Suspect B
- Studentwhat is in the middle of the strings
Bugscope Teamwe can see that the two things resting among the fibers are plant material
- Studentthese are also pollen right?
- Studentwhat are the dots
- Studentis that also pollen?
- StudentAre those bug eggs?
Bugscope Teamthose are pollen grains, but I have seen fruitfly eggs that looked similar to these
- StudentIs this hair?
Bugscope Teamno it's the fibers that make up the individual threads in the shoelace
- StudentAre those little specks by the pollen dust? Or more pollen?
- StudentOh, okay Cate.
- 11:21 am
- StudentWhat are the round things?
Bugscope Teamthose are pollen grains that look like lily pollen
- Studentis there dirt in between the shoe strings?
Bugscope Teamyes there is some dirt there
- Studentis that the shoelace?
- Bugscope Teamfruitflies like rotting fruit
- StudentIn one of the pollen grains, it looks as if one is opening? what is it?
- Studenthow come some of the pollen grains are open?
- StudentWhy do the pollen grains look scaley?
- StudentDo fruitflies hang out near little bushes or flowers?
Bugscope Teamnot unless they are in warm areas and the bushes or flowers produce fruit that would attract the fruitflies
- Studenthow come the pollen is rough looking
Bugscope Teamlikely it helps the grains maintain their shape and also helps them stick to things
- Studenthow did the pollen get in the shoe lace?
Bugscope Teamsomeone must have been walking on flowers? or they work at a florist
- StudentWhere does the pollen come from?
- Studentthe bush or flower
- TeacherLily pollen? Can you speculate what type of pollen the other sample was?
Bugscope Teamthat is not something we have seen before
- Bugscope Teamyou can get pollen on you from just walking in grass or plants sometimes
- Studentwhat is that
- Studentis the shoe lace torn
- StudentWhat pollen is that?
- Studentwhat is that big chunk
- Studentis that dried pollen
- Studentwhy is it all tangled up
- Bugscope Teamthis is a big pole of pollen and plant fibers
- StudentIs the shoelace tangled or something?
- Studentwhat is theplant looking stuff
- Studentlooks like seeds? between the strings
- Bugscope Teampile*
- Bugscope Teamthis is a clump of fibrous plant material that has pollen in it
- Studentdoes moisture keep the fibres and pollen together?
- TeacherWe are now on Suspect C
- StudentWhat type of plant pollen is that?
- StudentWhat's a fibrous plant?
- Studenthow would pollen collect like that?
- StudentWhat type of plant fibers?
Bugscope Teambecause the pollen is in it, those fibers may be part of the anthers of whatever kind of flower that is
- 11:26 am
- Studentthis means they were near flowes?
- Studentwhat are those lottle dots bettwen the strings
- Bugscope Teami don't know what plant this came from
- Studentwhat kind of plant is this pollen from
- Bugscope Teamthe pollens looks like squishy balls
- StudentIs the pollen sticky?
- Studentso it could be any plant. right?
- StudentWhat are anthers?
Bugscope Teamanthers are the tip top part of the stamens that produce pollen in a flower
- Studentis this crushed?
- Studentare these strings that keep the pollen stuck to it
Bugscope Teamthese are the shoelace fabric fibers
- Bugscope Teamyou can see how the pollen grains can easily get tangled in it
- Studentlooks like b
- StudentWhat are the specs?
Bugscope Teamthe specks are pollen grains
- StudentIs this pollen to?
- Studenthow did they get in between the threads?
- Student Can fibers trap everthing?
Bugscope Teamit's easy for something this small to get stuck in it
- Studenthow would fiber stick to thing easily or would it only react to types of fabric?
- Studentit seems like there is more pollen
- Studentis this still the same pollen?
- Bugscope Teamthis is pollen found at the crime scene
- StudentIt looks like it is trying to come out of the thread
- StudentThe pollen here looks like the pollen on B. Is it the same type?
- Studentdo the indents in the pollen help it to stay in one place?
- Studenthow come some of the pollin has stuff sticking out
- Studentcan this pollen be felt by our hands
- StudentThis looks the most like B, hmmmmm...
- StudentIs this the same pollen as the one in sample b?
- Studentlooks like b. Is that the same type of pollen from suspect B?
- StudentWhat type of pollen?
Bugscope Teamwe do not know for sure what type of pollen this is, but it looks very much, to us, like pollen that comes from lilies
- Bugscope Teamwe are on the crime scene shoelace. If it looks like B, then maybe that tells you something
- 11:31 am
- Studentit looks very similar to the lace on "b"
- Studentis there an area that would have more pollen than another?
Bugscope Teamthe anthers will have more pollen than any other flower part
- Studentif the srings get riped will the polen be able to get out
- StudentLillies are plants right?
Bugscope Teamyes they are plants with cool-looking flowers
- Studentwill the pollen always get stuck there, or will it get blown away?
Bugscope Teamit could get blown away
- TeacherRemember we had numerous pieces of evidence. You must consider the hair samples, the circumstantial evidence at the crime scene, the handwritng samples, and the statement from the librarian. We must also not forget motive.
- Studentlike whatkinds of flowers
- Studentit loks like some ofthe fibers are torn
- Studentthis was found outside right?
Bugscope Teamit seems likely it was found outside
- StudentDo some pollen grow?
- TeacherThank you always Bugscope team! I believe we now have the information we need to solve our crime.
- Studentit looks like the fiber is torn
- Studentthank you!
- Studentthank you so much have a nice day
- StudentThank you!
- Studentthank you
- Studentthank you so much
- StudentBye and Thank you very much!
- Bugscope Teamwe have our own ideas now
- Studentthank you very for your time
- StudentThanks scot for ansering my questions!
- StudentThank You goodbye!
- Bugscope Teamit does look torn
- StudentThank you for your awsomeness!
- StudentThank you bugscope team, I would love to do this some other time!
- Studentthank you for your help
- StudentGoodbye, and thank you!
- Bugscope Teamthis was fun for us!
- StudentThank you so much, you where very helpful. I think I know who the criminal is now. You're awsome!
- Studentus too
- Studentit was fun for us to!
- Bugscope TeamGood bye, everyone!
- Bugscope TeamBye!
- Bugscope Teamabientot!
- Bugscope Teamau revoir
- Bugscope Teama bientot
- 11:36 am
- Studentsee ya!
- Bugscope Teamô
- Bugscope Teamsee ya!
