2. Chemistry Do Now 3-19-19 Key Put oxygen-18 through 2 alpha decays.
188O  42He + 146C  42He + 104Be
Put oxygen-18 through 2 beta decays.
188O  0-1e + 189F  0-1e Ne
Put nitrogen-15 through an alpha decay then a beta decay.

3618Ar  42He S
3215P  0-1e S
3717Cl  3315P + 42He
3717Cl  3718Ar + 0-1e

3. Objective(s)
Students will know how does radiation impact everyday life by taking notes, reading articles and completing a worksheet
Mastery Level: 75% or better on the article questions and worksheet

4. Reminders i-Ready testing ends this Friday, March 22, 2019.
3rd Quarter ends on April 3, 2019 (11 school days).
Due to death in my family, I will be out the rest of the week. I will leave work for you to do each day. Please do not cut class or ignore the work left for you to complete; it will count towards your 3rd quarter grade. I will see you on Monday!

5. Engage
Students watch the video: The Most Radioactive Places on Earth (by Veritasium runtime = 11:17). As they watch the video, students will answer questions.

6. Radioactive Decay - RECAP
Radioactive decay results in the emission of either:
an alpha particle (a), 42He nucleus + energy
a beta particle (b), 0-1 e (electron) + energy
or a gamma ray(g), no particle, just energy

7. An Overview of Nuclear Decay
Helium nucleus or α particle
Electron or β particle
Gamma radiation

8. Extend/Evaluation
PART 1: Students develop their own visual model of each type of radioactive decay (alpha, beta, gamma), focusing on the particles involved and the penetration ability for each.
PART 2: Students will read about diagnostic applications of nuclear medicine or about therapeutic applications of nuclear medicine from the Radioisotopes Brochure from the NRC. Students should record what they believe are three key points or facts from their assigned section. Students then form groups of 4 containing 2 students who read about therapeutic applications and 2 students who read about diagnostic applications. In their groups, students share what they have learned in order to compose a group public service announcement (PSA) brochure about the benefits of nuclear chemistry in medicine.

9. Evaluation Exit Ticket Question
What happens to particles and energy during:
Alpha radioactive decay?
Beta radioactive decay?
Gamma radioactive decay?
