What reactions created the different elements in a cell phone?¶
Learning Objectives:¶
- Explore the origin of the elements by modeling nuclear reactions, specifically nuclear fusion.
- Identify the differences between alpha decay and beta decay.
- Describe characteristics and equations of nuclear fission and nuclear fusion.
- Compare and contrast alpha, beta, and gamma radiation.
Warm-up:¶
- Attendance
- Open Student IMT Unit 5, make sure all lessons are complete.
IN-CLASS WORK:¶
- Open L5.4 Student Sheet , make a copy and add to your google drive
- Last part of class work on practice problems
- End class with review - what was learned today?
OUT-OF-CLASS WORK:¶
- Open IMT for Unit 5 and make sure all sections for lesson 4 are complete.
- Make sure student sheet L5.4 is complete and complete Edpuzzle on schoology.

Review: #1 How does this image support your learning from our last class?
2 What is the difference between nuclear fusion and nuclear fission?¶
Part 1 - Activity: Play Nuclear Quest and Answer Questions
Part 2: Nuclear Quest and Types of Radiation Go over answers from Nuclear Quest Game Using the Types of Radiation video and help from your teacher, complete the table below.
| Type of radiation/particle | Particle or Energy? | Greek Symbol | Isotopic Symbol | What stops it? |
|---|---|---|---|---|
| Alpha | Particle | \(\(\alpha\)\) | He | Paper, clothes |
| Beta | Particle | \(\(\beta\)\) | e | Aluminum, plastic |
| Gamma | Energy | \(\(\gamma\)\) | NA | Lead, Concrete |
| Neutron | Particle | NA | NA | Lead, Concrete |
Part 3 - Equations showing each reaction:
Nuclear Fusion: Use the image to the right to fill out the blank ‘--’ spaces below
1-H + 1-H → 2-He + Ɣ energy
2-He + 2-He →11H + 11H + 2-He + Ɣ (energy)
Nuclear Fission: Use the equation below to complete blank spaces in the image to the right 92235U +01n →92236U →56144Ba +3689Kr + 301n + Ɣ
PRACTICE PROBLEMS:
NEXT STEPS: Reflect on today’s question: What reactions created the different elements in a cell phone? Open up the IMT for this unit, complete all boxes for lesson 4 Make sure all parts of the L5.4 student sheet are complete and complete the check for understanding on Schoology. See agenda on schoology for review resources!
