| 00:24 | going to be observing and exploring crickets and what it | |
| 00:28 | has to do and going to have to do with | |
| 00:31 | our with our With our food chain . Okay so | |
| 00:37 | we're developing our food chain . Please turn to page | |
| 00:40 | 19 in your journals . Now , what we're going | |
| 00:46 | to do is we're going to get our materials managers | |
| 00:50 | and I've got a tray of objects and let's show | |
| 00:52 | you those objects first . Okay I'm going to you're | |
| 00:56 | going to get materials managers are going to get a | |
| 01:00 | tray and on the trail . You've got a container | |

| 01:11 | . Okay . You're also going to get for magnifying | |
| 01:17 | glasses . Okay wow . Once this is on your | |
| 01:22 | table , mm . Yeah the materials managers can come | |

| 03:49 | me why . Okay , Isabelle , I think a | |
| 03:54 | creek , it's not an integer because insects , most | |
| 03:57 | insects have six legs and crickets only have four . | |
| 04:00 | Okay . Okay . So you think it only has | |
| 04:03 | four ? Does uh , does anyone want to add | |

| 04:38 | , It sucked me in jail and I think it's | |
| 04:41 | an insult because it has six legs . Um , | |
| 04:44 | they needed like somewhere to live like in grass and | |
| 04:48 | also , and they need to like I saw you | |
| 04:50 | so they can dig on the ground . Okay . | |
| 04:52 | All right . Well with that in mind . And | |
| 04:55 | guys , you've had awesome and uh , conversation and | |
| 04:59 | good feedback . Excuse me . And also has some | |
| 05:03 | tennis . Okay , good , good , good . | |

| 05:12 | you to take your magnify IRS and your eyes and | |
| 05:14 | we're going to observe carefully . You're going to do | |
| 05:17 | numbers one and two . That means you are going | |
| 05:20 | to draw your , going to absorb the crickets in | |
| 05:22 | your container . You're gonna draw a large picture of | |
| 05:26 | one of the crickets and then you're gonna use your | |
| 05:29 | chart at the bottom there and you're going to answer | |
| 05:34 | question to Do you think a quick it is an | |
| 05:36 | insect ? Why or why not ? So you're gonna | |
| 05:38 | have to prove it with your drawing And don't forget | |
| 05:42 | to label when you draw . Way you have to | |
| 05:52 | wait . Did you look at your chart ? Can | |
| 06:08 | you find everything ? Can you find everything on the | |
| 06:12 | way A I like the way you're starting your drawing | |
| 06:20 | . Remember to label your drawings , go ahead and | |
| 06:23 | start your drawing finish your drawing hunt . I want | |
| 06:29 | it turned around . There we go . Did you | |
| 06:35 | check and make sure that it has everything that's on | |
| 06:38 | the chart ? Yes , you did . Yeah . | |
| 06:43 | Okay . Can you draw it for me ? Draw | |
| 06:47 | and label label the parts for me ? I like | |
| 06:51 | the way you're using your chart to help you with | |
| 06:54 | your good job . What you're gonna do is like | |
| 06:57 | you're going to draw a line like this and write | |
| 06:59 | what that part is . You're going to draw a | |
| 07:01 | line like this and and write down the word for | |
| 07:05 | that part . Okay , So you're gonna name all | |
| 07:06 | the parts for me . Okay , boys and girls | |
| 07:13 | give me five . Look at me and give me | |
| 07:16 | five . Look at me and give me five . | |
| 07:19 | I like the way your hands are free . I | |
| 07:23 | like that . All eyes are on me , right | |
| 07:26 | , Isaiah . Right . Drake . Thank you . | |

| 11:49 | abdomen . Good job . Now one thing that a | |
| 11:54 | lot of you and I noticed that uh drake had | |
| 12:00 | these on his um drawing and notice there is another | |
| 12:10 | extension here . Does anyone look at your look carefully | |
| 12:13 | at your uh cricket ? Does yours have this ? | |
| 12:19 | It looks like a stick on the end there . | |
| 12:21 | Does it have that extension at the end ? Some | |
| 12:26 | will some won't yeah some will some won't raise your | |
| 12:35 | hand . If you're a cricket raise your hand . | |
| 12:39 | If you if you have a cricket that has that | |
| 12:41 | extension raise that raise your hand . You might not | |
| 12:46 | have won . And that's okay . Um Okay look | |
| 12:50 | up here . Put your crickets down look up here | |
| 12:55 | . Okay this is called . And over depositor . | |
| 13:02 | This is an over posit or what that does . | |
| 13:04 | That's on females . And it's a tube . And | |
| 13:08 | what that tube does is it delivers the eggs , | |
| 13:12 | the eggs go through that tube and they delivered in | |
| 13:16 | the ground . Okay . And so that's how they | |
| 13:19 | deliver their eggs , their little babies , their little | |
| 13:22 | eggs . Okay . Uh huh . For fertilization and | |
| 13:27 | growth . Okay so that's an over posit . Er | |
| 13:31 | Now if I want you to turn to page 19 | |
| 13:38 | you're going to answer three and four because you're gonna | |
| 13:42 | look to see if you can find the following body | |
| 13:44 | parts on your cricket . If you don't have it | |
| 13:46 | labeled on your cricket , please label the body parts | |
| 13:50 | . Okay . Yes , I still have my classroom | |
| 13:53 | from earlier . I'm one of those two lines on | |
| 13:57 | the back of them . Okay . Those um or | |
| 14:01 | like Celia there their little hairs . Their little hairs | |
| 14:06 | . And what they do , what do you think | |
| 14:07 | they might do ? Mhm . How would it help | |
| 14:12 | them in case they get lost ? Okay . He | |
| 14:18 | is right that their sensors he is right that their | |
| 14:21 | sensors so they can feel uh fuel . And plus | |
| 14:25 | it helps . Have you heard the crickets make the | |
| 14:27 | noise when they rub their legs ? Okay . That | |
| 14:30 | also helps in that too because it's got the little | |
| 14:33 | uh they had the little hairy parts on those back | |
| 14:36 | legs . And um it is the males that make | |
| 14:41 | the noise not the females because one is going to | |
| 14:48 | sing . Uh they want to compete for the females | |
| 14:52 | and so they want to say I'm the prettiest singer | |
| 14:56 | . So they're going to do that . Okay . | |

| 15:14 | your group and we're going to let the leaders do | |
| 15:18 | that . The leader in each group is going to | |
| 15:20 | have that job and you're going to just gently touch | |
| 15:25 | it . I'm not gonna do it for you because | |
| 15:26 | I want you to observe what happens when you just | |
| 15:29 | gently touch the intent . You're not gonna stab it | |
| 15:31 | . You're just gonna gently touch that antenna . Okay | |
| 15:36 | , gently touch that antenna and see what you're doing | |
| 15:40 | . No , just one person look . But you | |
| 15:43 | need to observe what he does . Please write down | |
| 15:50 | your observations , put the lid back on the container | |

| 17:30 | antenna ? When we was trying to touch the and | |
| 17:36 | I mean , the cricket with the pencil kept on | |
| 17:39 | running away in circles and , and we didn't get | |
| 17:44 | the touch it because it kept on jumping . Well | |
| 17:48 | , we touched it a couple of times , but | |
| 17:49 | when we actually did touch it , there were sometimes | |
| 17:53 | we touched it a couple of times that it stayed | |
| 17:55 | still and we tried to touch it again during the | |
| 17:57 | second time . I tried to touch it ran off | |
| 18:00 | . Okay . All right , Nice job . Okay | |
| 18:03 | . I would like my materials people to come up | |
| 18:08 | here . What you're going to do , what the | |
| 18:11 | material managers are going to do when they get back | |
| 18:15 | to their , uh , desks . They're going to | |
| 18:19 | fold their their piece of construction paper in half . | |
| 18:24 | They're going to make a tent . It's gonna look | |
| 18:26 | like a tent . And we're going to see what | |
| 18:30 | happens when we put this little tent inside the container | |
| 18:37 | . What do you think the cricket will do ? | |
| 18:39 | First of all , I want you to turn to | |
| 18:41 | someone in your group and I want you to within | |
| 18:44 | your group . Talk about you going back , talk | |
| 18:46 | about what you think might happen When this is in | |
| 18:49 | there . Give Me five . Give Me five . | |
| 19:01 | Give Me five . What do you think will happen | |
| 19:07 | ? Didn't what do you think will happen when the | |
| 19:11 | tent is placed inside the container ? What do you | |
| 19:16 | think ? I thought they would just go inside of | |
| 19:19 | it and hide ? Okay . All right , jay | |
| 19:25 | . I think it might be trying to um smelled | |
| 19:28 | or get the sense or something to figure out what | |
| 19:31 | it is . Because most of the crickets do do | |
| 19:35 | that in cases like a case is like a danger | |
| 19:39 | or something . Okay . Do you think he'll go | |
| 19:42 | inside it or go on top of it or what | |
| 19:45 | do you think he'll do ? I think he's gonna | |
| 19:47 | gonna shine . Okay . All right . All right | |
| 19:51 | , let's observe . Please put these you can open | |
| 19:55 | up the k just have your friends have the team | |
| 19:57 | do it together and make sure put the lid back | |
| 20:01 | on top so that the cricket doesn't hop out . | |
| 20:05 | Okay ? Now give it a few minutes . Let's | |
| 20:08 | see what happens after a few minutes . Just just | |
