Grab binders handouts begin the Do Now 35

Grab binders & handouts, begin the Do Now 3/5 DO NOW 1. The same radioactive poison, Polonium (Po), that was used to kill the Russian spy was rubbed on the pen you are using to write. Are you concerned? Why or why not? 2. List any positive AND negative applications of radiation you can recall.

Energy Sources Jigsaw Directions: • 30 minutes to complete • Group of 4 • Each person selects 1 energy source article to complete a jigsaw for • Group members present notes to peers • When finished call over Ms. Herndon to receive materials for the second step DO NOT write on the articles!

The world can't afford another Fukushima or Chernobyl nuclear disaster Greenpeace Quick Facts: - There is nothing "peaceful" about all things nuclear. The risks from nuclear energy are real, inherent and long -lasting. - November 2000 - the world recognized nuclear power as a dangerous and unnecessary technology - April 2001 - United Nations Sustainable Development Conference refused to label nuclear a sustainable technology in April 2001.

• • Chernobyl Disaster When – April 1986 Cause – nuclear reactor malfunction - largest uncontrolled release of radioactive waste into the environment - release of radioactive materials lasted for 10 days Location – Chernobyl, Ukraine Affected countries – Ukraine, Belarus, Russia Main radioactive wastes: Iodine – 131 Cesium – 137 Radioactive materials settled down in dust and debris, but lighter materials were carried by wind across countries Caused 28 deaths within 3 months; plant is still in use today

Long-lasting Effects of Nuclear Power Meltdowns • As you watch the following Greenpeace video, add any pitfalls you hear about from the videos to the Pitfalls column on your T-Chart

Fukushima Daiichi Nuclear Melt Down • Location: Japan • When: March 2011 • Cause: natural disaster (earthquake & tsunami)

Fukushima Daiichi Nuclear Melt Down • Initial uncontrolled radioactive leakage, then deliberate venting to reduce risk of explosion • Trace amounts of radiation found throughout the world: Iodine – 131 Cesium – 137 • Large amounts of radioactive materials found in the Pacific Ocean • Radiation released = 1/10 the released amount seen during the Chernobyl Accident • Radioactive materials contaminated the nation’s food spinach fish milk beef • August 2011 – still leaking low levels of radiation, areas surrounding nuclear power plant can remain uninhabitable for decades

Figure 1. Fukushima Nuclear Meltdown Radiation Dosage

Benefits vs. Risks Stations! Directions: Answer the following questions based on Figure 1. Fukushima Nuclear Melt Down Radiation Dosages. According to Figure 1, during what time frame was the largest release of radiation observed? A) Based on Figure 1, what was the largest radioactive dosage rate seen during the Fukushima nuclear power plant melt down? B) When did this large dosage occur?

Benefits vs. Risks Stations! • • 6 stations 6 minutes at each station Leave data at the stations If finished before 6 minutes is up, check your answers against your group members. DO NOT move forward until told to do so. • You are turning in this packet to Ms. Herndon for credit

Exit Ticket 6 Complete Exit Ticket 6 silently and independently. At the bottom of your Exit Ticket Answer the following questions: 1. What are some effects of being exposed to radiation? 2. Would you support the use of Nuclear Power? Why or why not? When finished with your exit ticket submit it, as well as the stations work, to the class bucket and put away your binder.
