Nuclear Chemistry Lesson Plan


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.


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


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.
