    in groups (4-5 students) Laboratory: look slides of bone tissue with microscope: each group writes a report-The students use what they have learned at home
Notes:
Students already know how to use the microscope ;they can use what they learned at home. Teacher observes groups working and helps them, if necessary. The classis is "flippped"

    In groups students prepare a power point presentation with advice for astronauts and for people to prevent osteoporosis students can use prezi
Notes:
Students are used to working in groups: the groups (5 students each) have already been formed. The students and the teacher do as in the Collaborative work - Towards a healthy city (look at resources)

Students evaluate their work with a Peer Evaluation Form http://www.lapresenter.com/coopevalpacket.pdf Teacher uses a Grading Rubric to evaluate power point presentation http://txla.org/sites/tla/files/groups/YART/docs/2015SPOTHigh-Fehlbaum_AcademicProgram_PowerPointRubric.pdf Teacher uses a grading rubric to evaluate student's work. For a summative assessment the teacher can assess whether all of the outcomes have been achieved by all students with tests and/ or open questions
