- 2:58 pm
- Bugscope Teamhi ronit
- Bugscope Teamwelcome to bugscope
- TeacherHi My name is Ronit and I am the first grade teacher for this class at the Willows Community School. Currently the class is running late. They should be here soon
- TeacherHi cate
- TeacherI am new to this. It is my first time
- Bugscope Teamok well you have control of the microscope
- Bugscope Teamyou can click on a preset to the lower right if you want to move the microscope to a certain insect
- TeacherI will practice until the class comes in.
- Bugscope Teamyeah Welcome to Bugscope!
- Bugscope Teamyou can also drive around and change the magnification. with the navigation tools, you will have more control with the click to center
- Teacherhow do I stop it
- Bugscope Teamif you click to drive, you need to click to stop
- Teacheror reset
- Bugscope Teamif you get lost, click on a preset
- Bugscope Teamthat's why it is sometimes easier to use click to center to get around
- Bugscope Teamthe edge of the world
- Bugscope Teamthat is a screw in the stage
- TeacherI clicked on the preset but it keeps coming to this
- Teacherthe class has just arrived and sat down
- 3:05 pm
- TeacherWhat is that the class wants to know
Bugscope Teamit's a caterpillar. we don't know what kind though.
- Bugscope Teamit's upside down, the bottom is the head
- TeacherHow big is it really
- Bugscope Teamyou can tell they are insects because they have six legs
- Bugscope Teamit'
- Bugscope Teams a few mm long
- Bugscope Teamsee the micron bar in the lower left corner of the screen? that is 0.7 mm
- TeacherDoes the caterpillar have hair all over
Bugscope Teamyes, you will find that all insects have hair on them, some more than others. The hair on insects are called setae, since they arent mammals
- Bugscope TeamPlease try another preset when you want, and let us know which one keeps taking you off the stage.
- Bugscope Teamsee the answer to the left?
- Bugscope Teamthe setae are useful in giving the insects information on what is going on around it, like taste/smell and touch
- Bugscope Teamwhich preset was that?
- Teacherwhat part is that
- Teacherthe class wants it to stop so they can see
- 3:10 pm
- Bugscope Teamthat was the antenna of the beetle
- Bugscope Teamand this is the underside of its head
- TeacherSo now we are lloking at beetles?
- Teacherlooking
- TeacherWhat kind of beetle?
Bugscope TeamI think this is a ground beetle of some sort- basically a black beetle
- TeacherWe have been studying mealworms. They turn into beetles. We tasted mealworms today, different flavors
Bugscope Teamwow were any of them good?
- TeacherIs it the bottom side?
- Bugscope Teamreally they come in flavors?
- Bugscope Teamyes this is the underside of the head
- TeacherWe tried cheddar cheese, BBQ and Mexican spice
- TeacherYes they enjoyed tasting them
- Bugscope Teamwe put most insects on the backs, because usually the backs are just smooth and uninteresting
- Bugscope TeamCate would like the BBQ ones.
- Bugscope Teamyeah probably :) as long as they arent squirming
- Bugscope TeamIs this something your school district is trying out?
- Bugscope Teamand i cant tell what they are haha
- Bugscope Teamgood protein
- TeacherWE ordered them from a special place that sells edible insect snacks
- Bugscope Teamwow
- TeacherWhat are the feathery parts next to the legs of this beetle
Bugscope Teamthose are accessory mouthparts
- Bugscope Teamthe things that look like legs are palps
- 3:15 pm
- Bugscope Team'cause this is just the head! it is a large beetle
- Bugscope Teamthe jointed things are the antennae
- TeacherWhat do the palps do?
Bugscope Teamthey taste and move around the beetle's food
- Bugscope Teamthey have little taste buds at the tips, and the taste buds let the beetle know if it would like to eat that particular thing
- Bugscope Teampalps are legs, in a way -- they are modified legs, but way back in time so we don't think of them as legs
- TeacherWe have never seen palps or heard of them from all our books that we have read so far
- Bugscope Teamsee the jaws -- also called mandibles?
- TeacherWe know they have mandibles to grab
- TeacherDoes this beetle have wings?
Bugscope Teamuse click to center to drive down the body and see if we see any wings
- Bugscope Teamthe two sharp-looking crossed things beneath the palps (from our perspective) are the mandibles
- Bugscope Teamcool!
- 3:20 pm
- Bugscope Teamnow we see the thorax
- Bugscope Teamand the edge of one of the legs!
- Bugscope Teamthere are little scales, it looks like, on the surface of the thorax
- Bugscope Teamif they are scales, they are not from the beetle but likely from a moth or butterfly
- TeacherColin wants to know what the big round thing in the middle of the thorax is?
Bugscope Teamyeah we got some of these insects from a collection that an entomologist had
- Bugscope Teamyou can drive down a little more and you will see!
- Bugscope TeamThe base of the leg is called a 'condyle.'
- Bugscope Teamnow we can see that the body of this beetle is jointed, almost like that of a click beetle
- TeacherIt looks like a jointed thorax, is that correct?
- Bugscope Teamyes!
- Bugscope Teamuh oh!
- TeacherWe are heading down to see the last set of legs
- Bugscope Teamyou can sort of guess where that hole came from
- TeacherWE are just discussing it but can you fill us in?
- TeacherSome of us think that you drilled a hole and took the insides out
- Bugscope Teamit's from a pin that went through the body
- Bugscope Teamso in a way it was a drilled hole
- 3:25 pm
- TeacherBefore they pin an insect do they need to drain the inside of an insect?
Bugscope Teamthey usually just poke it and don't bother to drain it
- Bugscope Teamif you wanted you could follow one of the legs out to the claws
- Bugscope Teamwhen we prepare insects that are alive, we freeze them, then we just let them dry out on their own
- TeacherWe are trying to make our way to the end of the legs to see the claws
- TeacherCan you help us get there and we will wait
- TeacherThank you
- Bugscope Teamthe arms/legs are sort of the same, and they have a condyle, a femur like we do, a tibia like we do (but not a fibula), and then the forearm segments are called 'tarsi.'
- 3:30 pm
- Bugscope Teamthere can be four or five tarsi, and at the end is the claw
- TeacherThank you Scot and Cate. This was a lot of fun and very informative. We have to go to our All School Meeting but we will visit again. Can we come and see another class doing their session?
- TeacherThis is really cool
- Bugscope Teamthanks for using bugscope
- Bugscope Teamwe don't have any other classes today... ;(
- TeacherAre the legs made from bone
Bugscope Teamthe legs are made of chitin, on the outside
- TeacherBut we can look on the schedule and see what is coming up, right?
- Bugscope Teamyou can come and log in whenever we have another session and check out what's going on. the upcoming sessions can be seen from the main bugscope page
- Teacherthank you again, hope to see you soon. bye
- Bugscope Teaminsects do not have bone, so even though I told you the segments have names like human bones, they are not bones
- Bugscope TeamThank You!
