### Nuclear Chemistry Lesson Plan

#### Content

Half-life or a Radioactive isotope

Half-life, radioactive, nuclide, decay

#### Goals / Aims of The Lesson Plan

1.Determine half-life by looking at a diagram

2.Plot a graph of radioactive decay

3.Interpret graph of half-life sequences.

#### Objectives

1. Describe the type of decay a radioisotope undergoes

2. Solve problems that involve half-life

3. Simulate the decay of a radioisotope

4. What are groups in a periodic table? How may are there?

5. What are periods in a periodic table? How many are there?

6. How many known elements are there?

#### Materials and Aids

graph paper, ruler, penny, textbook, drawing; computer w/interactive textbook

### Procedure

**A. Introduction-**

Read pg. 799 & look up vocabulary words radioactive, radiation & radioisotopy & infer that radio means "to send out in all directions"

**B. Development-**

1. Use Elmo to define vocabulary

2. Passout Venn and Cycle diagrams & explain how to read them

3. Students will develop a diagram based on a data chart of half life times
and sequences.

**C. Practice-**

1. Interpret diagram

2. Flip a penny to simulate radioactive decay

3. Plot data collected & make a labeled graph

**D. Independent Practice-**

1.Read pgs. 803-809

2.Do Interpreting graphs pg 805

3. We will get into chemical decomposition of nuclear reactions next class.
(Reminder for me)

**E. Accommodations (Differentiated Instruction)-**

1. G T - Explain & use exponential ideas

2. $1000 prize poster

3. Interpret 25-3 to make inferences about half-life

**F. Checking for understanding-**

1.Have students hold up plotted graphs to check

2.Section assessment - Students will take a 10 question quiz the beginning
of next class period.

**G. Closure-**

1.Review shape of graph

2. Vocabulary review

**H. Evaluation-**

1. Ticket or not- what is the half-life of carbon 14

2. Interactive textbook questions and refer to CFU section of this lesson
for quiz information.

**I. Reflection-**

Every time kids hear the word "Nuclear" they are scared. Maybe rightly so, but I hope to show them the power of Nuclear chemistry. We don't have enough highly motivated futurists in Nuclear Chemistry. Maybe I can help develop one.
