Week of April 12                                                                                       Chemistry (Blocks A, B, and C)

Begin class with 10 minutes of silent reading.  Students will write summaries of their readings in their Reading Journal.  Have students begin Lab 21-2: How Does Microwave Radiation Affect Seeds?  Discuss the types of radioactivity on pages 744-760.  Use Basic Concept Transparency 58: Types of Radioactivity to help illustrate the concept and have students do the worksheet by the same name.  Show video: A Look At Radiation.  Video is in VCR.

Learning Standard: 2.8 Describe alpha, beta, and gamma particles; discuss the properties of alpha, beta, and gamma radiation; and write balanced nuclear reactions.

Benchmark: Compare and contrast alpha, beta, and gamma radiation and apply the concept of half-life of a radioactive element.

Assignment:

Read pages 744-760.  Do Section 21.1: Types of Radioactivity Study Guide.

Begin class with 10 minutes of silent reading.  Students will write summaries of their readings in their Reading Journal.  Discuss nuclear reactions and energy on pages 761-767.  Use Basic Concept Transparency 59: Fission and Fusion to illustrate the concepts and have students do the worksheet by the same name. Show “Controlled” and “Uncontrolled” reactions animations at: http://www.visionlearning.com/library/flash_viewer.php?oid=2746.   Show Nuclear Power Plants PowerPoint Presentation and have students do miniLAB 21-2: A Nuclear Fission Chain Reaction on page 763.

Learning Standard: 2.9 Compare nuclear fission and nuclear fusion and mass defect.  2.10 Describe the process of radioactive decay as the spontaneous breakdown of certain unstable elements (radioactive) into new elements (radioactive or not) through the spontaneous emission by the nucleus of alpha or beta particles.  2.11 Explain the difference between stable and unstable isotopes.

Benchmark: Compare and contrast nuclear fission and nuclear fusion, compare and contrasts alpha, beta, and gamma radiation, demonstrate equations that represent the changes that occur during radioactive decay, and distinguish between stable and unstable isotopes.

Assignment:

Read pages 761-767.  Do Section 21.2: Nuclear Reactions and Energy Study Guide.

Begin class with 10 minutes of silent reading.  Students will write summaries of their readings in their Reading Journal.  Discuss nuclear tools on pages 768-779.  Use Basic Concepts Transparency 60: Sources of Radiation to show where radiation is found in the environment and have students do the worksheet by the same name.  Show the video: Managing Radiation.  Video is in VCR.  Complete Lab 21-2: How Does Microwave Radiation Affect Seeds?

 

Learning Standard: There are no learning standards that apply to this section.

Objectives: Distinguish the biological effects of radiation and the units used to measure levels of exposure and illustrate medical and nonmedical uses for radioactivity.

 

Assignment:

Read pages 768-779.  Do Section 21.3: Nuclear Tools Study Guide.

Begin class with 10 minutes of silent reading.  Students will write summaries of their readings in their Reading Journal.  Review for tomorrow’s test.  Students should complete Chapter 21: Nuclear Chemistry Chapter Review and Assessment in class.  They may then check their answers on the computer at: http://www.quia.com/tq/239676.html.

 

Learning Standard: Use a range of exploratory techniques.

Benchmark: Summarize the material covered this week in order to prepare students for tomorrow’s test.

 

Assignment:
