Science, Grade 6; 112.19. Science, Grade 7; 112.20. Science, Grade 8 (3) Scientific investigatin and reasning. The student uses critical thinking, scientific reasning, and prblem slving t make infrmed decisins and knws the cntributins f relevant scientists. The student is expected t: (A) in all fields f science, analyze, evaluate, and critique scientific explanatins by using empirical evidence, lgical reasning, and experimental and bservatinal testing, including examining all sides f scientific evidence f thse scientific explanatins, s as t encurage critical thinking by the student; (B) use mdels t represent aspects f the natural wrld such as a mdel f Earth's layers Lessn bjective(s): Students will learn abut pllinatin. Students will learn abut different pllinatrs and their characteristics. Students will design a flwer t attract a specific pllinatr. Differentiatin strategies t meet diverse learner needs: The teacher shuld ask students whether they prefer t read r watch vides t learn abut cncepts; then have students learn in their preferred learning style. Hwever, the teacher may assign students certain methds t imprve their skills. Fr example, if a student prefers reading, teachers may have them watch a vide and take ntes t imprve their listening skills. ELL students and students with learning disabilities shuld have multiple frms f instructin including visual and written instructin sheets as well as a verbal instructin and demnstratin. ENGAGEMENT (5 minutes) Teacher asks class what is pllinatin?. Class watches Ht Science Cl Talks #107 The Buzz Abut Bees with Dr. Shalene Jha (frm 3:44 4:35) available at www.htsciencecltalks.rg. Teacher asks class t share different types f fds, fruits r vegetables that depend n pllinatrs. Teacher can use pllinatr.rg/list_f_pllinated_fd.htm t find a list f fds that depend n different pllinatrs. Sme cmmn items that depend n pllinatrs include cffee, tmates, almnds, chclate! EXPLORATION (20 minutes) Class divides int six teams; each grup will research different pllinatrs. Each team will present a 3-minute presentatin abut their pllinatr and characteristics f plants they pllinate. EXPLANATION (35 minutes) Teams present a 3-minute presentatin abut pllinatrs and characteristics f plants they pllinate. Teacher highlights physical characteristics f pllinatrs as well as physical plant adaptatins that make it easier fr pllinatrs t pllinate plants. If time allws, watch An Orchid s Trap vide frm Nat Ge Wild shwcasing bees and rchids, 1

Using the infrmatin already prvided, grups design a mdel f a flwer that will attract that specific pllinatr. Teams must include a pster f the specific flwer characteristics that will attract their specific pllinatr including scent, clr and physical structures. Psters and mdels are displayed in a gallery walk. Each team evaluates the designs f three ther teams using the rubric prvided. EVALUATION (10 minutes) Mdels and psters are displayed in a gallery walk. Each team evaluates three ther teams designs using the rubric included.
