4. Objectives Objectives for the afternoon  another lesson from modeling chemistry with a few modifications  sharing my experiences with modeling

5. The lesson: Relative Mass  Content objectives: counting by massing and relative masses as the basis of the periodic table.  Language objectives: accurately follow oral directions given in English to complete the lab; use appropriate science terms and complete English sentences to complete the conclusion to the lab; speak in English using appropriate science terms while completing the lab and during the post lab discussion.

6. 5 - 7 Science Standards  1.1.2 conducts scientific investigations safely using appropriate tools and mathematics to gather, analyze & interpret data.  1.1.3 identifies relationship between evidence and logical conclusions.  1.1.4 communicates scientific procedures, results and explanations.  1.3.2 evaluates the work of others  7.2.1 …replicates historic experiments to understand principles of science…

7. 8-12 Science Standards  1.1.3 correctly uses the appropriate tools and mathematics in scientific investigations.  1.1.4 actively engages in conducting an inquiry…  1.1.5 reports and defends the design, results and conclusions of the investigation.  2A.2.2 understands the periodic table ….  7.3.1 demonstrates an understanding of the history of science.

8. ESOL Standards  1. The student listens to spoken English to develop communicative competence in academic language use.  2. The student speaks in English in academically appropriate ways.  4. The student writes technical text in English to achieve academic success in the content areas.

9. Clarification of Terms  Direct relationship = Directly proportional  When one quantity (variable ) changes, the second quantity (variable) changes in the same way.  Quantities and measurements have two parts: a number (magnitude) and a label or unit.
