Bellwork 10-2-2014Homework QuizFill in the blanks:

1. Alpha decay radiation emits an alpha particle that is also called helium. This element consists of 2 protons and 2 neutrons. The daughter element produced has 2 less protons and its mass is reduced by 4.

Ex. Chlorine-36 Phosphorus-32 + Helium-4

2. Beta decay radiation emits an electron with a mass of 0 and a atomic (proton) number of -1. A neutron is changed into a proton in the process. The daughter element produced has 1 more proton and the same mass.

Ex. Radium-222 Actinium-222 + electron-0

Fission and Fusion Basics

Fission: the splitting of one atoms nucleus into smaller parts to generate energy in attempt to power specific processes. Fusion: the combination of the nuclei of two atoms into one atom to generate energy in attempt ot power specific processes.

EfficiencyAn efficient process yields:

Energy gained > energy put inFissionRequires less energy than fusion but produces less energy output and we are running out of Uranium so it is not necessarily renewableFusionRequires 10x the energy in the core of the sun but can potentially produce more NET energy (5x more than fission)Safe, abundant and limitlessWe do not have enough tritium but we can breed it with sea water (deuterium) and fission of Lithium to make tritium

Group RolesEVERYONE: Quality Control

Researching - Assess group Contributing ideas members ideas, what

is being researched and written down

Facilitator: SpokespersonAssign individual roles (what to research, who is writing etc).Keep group on task

- Only one who talks to the teacher, ask questions to group members, stimulate good ideas

Step 1: Choose a Topic

Meet with your group and send the spokesperson to sign up for you nuclear energy process on the board. Once a topic is taken, you must choose something else!!

Key Pieces A – What is fission/fusion – how does it work?

What does the overall reaction look like?What common elements are involved?

C – What is this used for by us? What does it do for us?D – Efficiency

How much energy is gained from this process? How much is required to run it?Is more energy gained than used to power it?Usually given in eV or Joules

Step 2: ResearchYou will have the rest of the day to work with your group and research the topic you chose Research a-d(e) in step 2 on your handout

**Groups who have already had the intro should be done with at least A and B today. Others, part A

Make sure you keep track of the websites you visit for citations!! Recorder, write them down!

Exit Slip1. How successful were you in achieving your goal

today on a scale of 1-4? Explain why you chose the number you did.

4 = achieved my goal, feeling great about the work I did today.3 = I worked hard today but I did not accomplish everything I had planned2 = I did not work as hard as I should have and did not quite reach my goal1 = I was not productive today and did not come close to achieving my goal

Homework: IMPORTANT

Bring ALL chemistry work to school tomorrow for student lead conferencesDrop it off in my room in the morning so I can organize it by class period for parentsYour conferences will not be as useful to you if you do not have your work here for parents to see

Bellwork Quiz 10-9-2014If you were not here yesterday, get a research project

outline from the back counter and SILENTLY write down one goal you have for your research project with your group today after looking at the outline.

If you were here, answer the following questions, silently…1. Which reaction type did you have for the research

project, fission or fusion?2. Describe the process of fission OR fusion and how

it works.
