1 Grade Level: 10th Subject(s) Area: Bilgy Cell Divisin Unit Plan DAY ONE Cmputer & prjectr Cell Divisin PwerPint Cpies f ntes fr students (6 slides per page) Blank paper Netbks/cellphnes String (12 inch pieces, ne per student) Tilet paper & crepe paper Index cards fr Ticket-t-Leave Textbks Standard 4: Students understand the basic cncepts and principles f life science : Relate DNA, genes, & chrmsmes : Cmpare and cntrast the results f mitsis and meisis. Students will understand the steps f the cell cycle. Students will understand the relatinship between DNA and chrmsmes. Students will knw the fur stages f mitsis. Students will have a basic understanding f what happens during each stage f mitsis. Students will knw the end prduct f mitsis. Beginning Activity: Hw many cells are in the adult human bdy? Each student will text in their answer t Pll Everywhere. ( Students need t include their name and their answer. Check t see if anyne guessed the crrect answer. (100 trillin) If n ne guessed crrectly, write the crrect answer n the bard. Ask students leading questins t intrduce mitsis. Hw d we get s many cells? Are the cells the same? (muscle cells, skin cells, brain cells) Is the genetic material in the cells the same? Cell Divisin PwerPint Slides 1-4 Use ntes n slides t guide student discussin Hand ut sheets f paper (ne r a half-sheet per student) Have students make a diagram f the cell cycle Culd als insert a blank slide t draw cycle n s it is included in their ntes. Cell Divisin PwerPint Slides 5-7 Histne activity with string Hand each student a piece f string while they are wrking n their cell cycle drawings. Ask students t mdel DNA (string) wrapping arund a histne (their fist) Review key terms n the bard. Give students an index card with a cell vcabulary wrd n it t stick t the bard. Wrds: nucleus, centriles, nuclear envelpe, chrmatid, spindle fibers, cytplasm, chrmsme, cell membrane, centrmere Allw students t wrk tgether at their tables fr a few minutes befre they cme up t put their wrd n the bard.

2 While students are wrking n their vcabulary wrds, quickly sketch a cell n the bard. Students may use their bks r ld ntes t lk up the vcabulary wrds. Cell Divisin PwerPint Slides 8-13 Explain infrmatin slwly. Ask students t generate examples t cnnect the new vcabulary t things they knw (prphase=preparatin; metaphase=chrmsmes in Middle; anaphase=fighting sisters; telphase=telephne shape) Mitsis Skit Give students slips f paper with assigned rles. Need t have tw centriles All ther students will be paired as chrmatids. In a class with an dd number f students, ne student can help with the nuclear envelpe and spindle fibers. Use tilet paper fr the nuclear envelpe. Use string fr the spindle fibers Rearrange tables s that they frm a circular shape; they will be the cell membrane. PwerPint Slide 14 Ticket-t-Leave: Write dwn the 4 stages f mitsis in rder and ne questin yu still have. Remind students that they will have a quiz tmrrw. Check fr understanding thrughut the class perid by asking questins and bserving students wrk. Ticket-t-Leave at the end f class. Further assessment given n unit test. Reflectin:

3 DAY TWO Cmputer & prjectr Cell Divisin PwerPint Ores (6 fr every 4 students) Sprinkles (lng, rundish nes) Cpies f Ore Lab Quizzes Standard 1: Students understand the unifying cncepts and prcesses f science : Explain hw mdels can be used t illustrate scientific principles. Standard 4: Students understand the basic cncepts and principles f life science : Relate DNA, genes, & chrmsmes : Cmpare and cntrast the results f mitsis and meisis. Students will mdel the steps f mitsis with Ore ckies. Students will understand hw cell divisin is regulated. Students will knw the tw types f cancer tumrs. Students will brainstrm a list f carcingens. Mdeling Mitsis Activity Give students cpies f the lab Explain instructins. Students cannt eat any f the ckies until they have had the teacher check f all f the stages f mitsis. Review the definitin f a limitatin. Divide students int grups f fur; hand sanitize befre starting lab. Distribute ckies and sprinkles n paper twels. Discuss lab as a class. What were the limitatins? Give students a few minutes t review ntes. Mitsis/Cell Cycle Quiz Cell Divisin PwerPint Slides Use ntes n slides t guide student discussin. Check fr understanding thrughut the class perid by asking questins and bserving students wrk. Lab Questins Quiz n mitsis Further assessment given n unit test. Reflectin:

4 MITOSIS QUIZ NAME 1) Stage f mitsis when sister chrmatids are pulled apart 2) Hlds sister chrmatids tgether a. Anaphase b. Chrmsme c. Centrmere d. Histne 3) What stage f mitsis is shwn? 4) What is happening in number three? 5) Stage f mitsis when the chrmsmes line up in the center f the cell 6) True r False: Each half f a chrmsme is a centrmere. 7) The nuclear envelpe breaks apart during what stage f mitsis? Bnus: Hw many chrmsmes are in a human cell?

5 DAY THREE Cmputer & prjectr Cell Divisin PwerPint Cpies f vcabulary wrksheet List f terms t prject n bard Standard 4: Students understand the basic cncepts and principles f life science : Relate DNA, genes, & chrmsmes : Cmpare and cntrast the results f mitsis and meisis. Students will have a basic understanding f asexual reprductin. Students will knw the difference between smatic cells and gametes. Students will be able t define hmlgus chrmsmes. Students will understand the difference between diplid and haplid. Students will understand the difference between asexual and sexual reprductin. Cell Divisin PwerPint Slides Use ntes n printed cpy Vcabulary Wrksheet Students will wrk with partners t write vcabulary wrds, a basic definitin, a trigger wrd, and draw a picture t help them learn the terms. Vcabulary wrds t prject: Asexual reprductin Binary fissin Budding Cell differentiatin Smatic cells Gametes Hmlgus chrmsmes Autsmes Sex chrmsmes Sexual reprductin Fertilizatin Haplid Diplid Tell students that we will be playing a vcabulary review game tmrrw. Check fr understanding thrughut the class perid by asking questins and bserving students wrk. Vcabulary wrksheet. Further assessment given n unit test. Reflectin: Culd be mdified fr students with learning disabilities by writing in the terms.

7 DAY FOUR Cmputer & prjectr Cell Divisin PwerPint Index cards with vcabulary wrd n ne side, nn-matching definitin n the ther side. Use wrds frm yesterday s lessn. Shebx t drp vcabulary wrds int Timer/stpwatch/cell phne Index cards fr Ticket-t-Leave Standard 4: Students understand the basic cncepts and principles f life science : Cmpare and cntrast the results f mitsis and meisis. Students will demnstrate understanding f vcabulary wrds. Students will be intrduced t the prcess f meisis. Dr. Werner s Vcabulary Game: Class will be split int tw teams (13 students per team). Set up the classrm s that there is rm t mve frm ne end t the ther. The drpbx fr vcabulary wrds will be a ne end, the active team at the ther end. The nn-active team will be encuraged t pay attentin and listen s they knw the wrds/ definitins. Each student n the active team will receive an index card. N talking between the students befre the game starts. The teams will be timed. Student A will start the game by reading the definitin n the card. This student will stand next t the drpbx. Student B, the student with the matching definitin, runs t the drpbx and reads their definitin. Student A ges back t the active grup, but keeps their card (their definitin hasn t been read yet). After Student C cmes up t match Student B s definitin, Student B puts their card in the bx. Teacher checks fr accuracy f matching vcabulary/definitins. Faster team wins. Cell Divisin PwerPint Slides Relate the stages in meisis t the stages f mitsis. Ticket-t-Leave Name at least tw differences between mitsis and meisis. Include ne difference that we talked abut that wasn t n the PwerPint. Check fr understanding during vcabulary game. Ticket-t-Leave Further assessment given n unit test. Reflectin:

8 DAY FIVE Cpies f meisis flipbk Textbks Stapler Scissrs Clred pencils, markers, etc. Standard 4: Students understand the basic cncepts and principles f life science : Cmpare and cntrast the results f mitsis and meisis. Students will demnstrate understanding f the steps f meisis by making a flip bk. Shw example f a cmpleted flipbk. Distributed flipbk templates Each stage has several pages, s shw hw the chrmsmes, spindle fibers, etc. mve arund in the cell. Need t include nuclear envelpe, chrmsmes (tw pairs f hmlgus chrmsmes wuld prbably wrk best), centriles, and spindle fibers. Label these parts n yur first picture. Use the same clrs fr them thrugh the whle bk. Number yur pages befre yu cut them ut s they dn t get mixed up. Write a brief descriptin f each step n the page that labels that step. Bks will be graded n inclusin f nuclear envelpe, chrmsmes, centriles, and spindle fibers. Students will als receive credit fr describing what happens in each step. Further assessment given n unit test. Reflectin:
